WILLIAM M. CONLEY, District Judge.
This patent dispute presents a question of first impression with respect to the subject matter eligibility of a urine or other biological sample for drug screening and compliance protocols under 35 U.S.C. § 101, as well as related issues of enablement under § 112. The analysis is made more challenging by the state of flux in the treatment of competing goals inherent in § 101 challenges in recent years, and even in recent months. See Mayo Collaborative Services v. Prometheus Laboratories, Inc.,
Here, plaintiffs Ameritox, Ltd., and Marshfield Clinic, LLC allege that defendant Millennium Health, LLC infringes two of their patents: U.S. Patents No. 7,585,680 ("the '680 patent"), purporting to describe a method for drug screening and compliance protocols for one sample of urine from a patient on a prescribed medication regimen; and 7,785,895 ("the '895 patent"), purporting to describe a similar method for one biological sample generally. (See Am. Compl., Exs. A, B (dkt. ##106-1, 106-2).) Defendant Millennium seeks summary judgment of non-infringement and invalidity as to both patents. (Dkt. #126.) The parties also ask the court to construe various terms common to both patents, including most notably "known normative data" and "quantifying the concentration." (Def.'s Opening Br. (dkt. #130); Pl.'s Opp'n (dkt. #172).) For the reasons that follow, the court will deny Millennium's motion for summary judgment of non-infringement and invalidity with respect to the '680 patent and grant the motion with respect to the '895 patent, finding the patent invalid for lack of enablement under § 112. For many of the same reasons, the court finds the '895 patent is vulnerable to the application of the exclusionary principle under § 101, while the '680 patent is substantially less so.
Plaintiff Marshfield Clinic is a health care and research organization. Marshfield is also the assignee of the patents-in-suit from the inventors, Dr. Michael Larson and Dr. Thomas Richards.
Plaintiff Ameritox Ltd. is in the field of pain medication monitoring, including a provider of urine drug testing ("UDT") services. Ameritox is the exclusive licensee of the patents-in-suit pursuant to an exclusive license agreement between Ameritox and Marshfield dated March 15, 2010. In exchange for an exclusive license, Ameritox agreed to make certain royalty payments to Marshfield and to use good faith commercial efforts to develop, market, and sell a drug testing service based on the asserted patents.
Ameritox tests urine samples on behalf of doctors, nurses, and other health-care providers who prescribe pain medications to treat chronic pain. (Am. Compl. (dkt. #106) ¶¶ 7.) Ameritox describes its UDT service as being able to "help clinicians assess whether patients are correctly taking medications and whether the prescription
On May 16, 2011, Ameritox launched its current Rx Guardian CD service, which Ameritox asserts is based on the patents-in-suit.
By comparing the patient's normalized value to a range of values for other clinical patients believed to be prescribed and taking the same medication properly, the health care provider can better assess whether a patient is likely to be taking the prescribed drug in a manner consistent with the prescribed regimen. The three steps outlined above largely truncate the steps outlined in claim 1 of the '680 patent, which states:
('680 patent at 21:9-32.)
The patents-in-suit have a priority date of August 28, 2003, and cover a method to monitor medication usage and to detect aberrant drug usage patterns, including overuse and under-use of prescribed medications. ('680 patent at ABSTRACT.) The patents share the same specification, which states that adherence to a prescribed medication regimen is important to the success of most treatments, "particularly in patients in drug abuse or chronic pain programs." (Id. at 1:21-24.) The specification further describes a number of sources used by health care professionals to monitor medication usage, including interviews with patients, medical records, pill counts, prescription monitoring programs, and testing of biological samples, such as urine. (Id. at 1:42-48, 15:11-15.) The specification also states that urine drug screens available in 2003 were limited to reporting a positive or negative result because of "the large amount of variability in urine drug concentrations, mostly due to variations in hydration and urinary output volume." (Id. at 1:50-53.)
Both patents highlight problems with purely "up or down" test results. In particular, so long as patients took some amount of medication, their test results were positive and patients who overused or underused their medications continued to receive the same prescription:
(Id. at 2:61-3:3 (emphasis added).) In light of the problems in the prior art, the specification goes on to state that:
(Id. at 3:17-19, 4:50-54) (emphasis added).) The specification thus describes a method to "improve" or "enhance" medication monitoring and seeks to identify aberrant drug use. (Id. at 3:17-19.)
The description of the invention is also reflected in the prosecution history, including the inventors' statement that:
The Patent Office agreed with the inventors' submission leading to issuance of both patents. The patents also survived two more recent reexaminations, with the Patent Office issuing: the first reexamination certificates for the patents-in-suit in May and June 2013, leaving each of the challenged claims intact and issuing additional claims, and a second set of reexamination certificates on May and July 2014 — again leaving each of the challenged claims intact. (See id., Ex. 1 (dkt. #129-1) pp. 27-30; id., Ex. 2 (dkt. #1292) pp. 26-29.)
There are several references cited in the prosecution history (and by the parties themselves) that constitute prior art so well known by the "scientific community" at the time of the invention that it assists in determining whether the combination of elements in '680 patent constitute inventive concept. See Mayo, 132 S.Ct. at 1298 (patent is invalid if any additional steps consist of well-understood, routine, conventional activity already engaged in by the scientific community). In reviewing these references, the court is mindful that when prior art is put into evidence — either existing as part of the prosecution history or cited in expert reports — the reference must be considered in its entirety, i.e., as a whole, including portions that would teach or steer away from the claimed invention. W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540, 1550 (Fed.Cir.1983).
One of the most relevant prior art references in this case is the George Article. S. George & R.A. Braithwaite, A Pilot Study to Determine the Usefulness of the Urinary Excretion of Methadone and its Primary Metabolite (EDDP) as Potential Markers of Compliance in Methadone Detoxification Programs, J. ANALYTICAL TOXICOL., Mar./Apr.1999, at 81-85. (See Mandel Decl., Ex. 43 (dkt. #129-43).) The authors of the George Article investigate urinary excretion to determine whether "methadone or EDDP could be a simple and noninvasive marker of methadone compliance." (Id. at 83.) Testing was specifically performed "to try to resolve the issue of whether urinary excretion could be used in place of plasma concentration as a mechanism to monitor compliance during methadone replacement therapy for opiate addiction." (Id. (emphasis added).)
The George Article was cited before the Patent Office, and it is also cited at length in Dr. Wu's expert report, opining that the patents were invalid on §§ 101, 102 and
(Orsulak Rebuttal Rept. (dkt. #118) ¶ 59.)
As Dr. Orsulak points out, the George Article "never compares the results from any of the 56 drug abusers to the 14 control subjects. Rather, to the extent any comparison is made, the George article only discloses comparing a patient's test result to earlier results from that same patient." (Id. at ¶ 86 (emphasis added).) "In other words, the George article discloses a straight historical results analysis, without any 95% inclusion range being involved, nor is any comparison to a known normative database disclosed." (Id.) Thus, the "only comparison disclosed in the George article is a single patient's test result to his/her own earlier test results." (Id.) These facts were not squarely controverted in Dr. Wu's opinion, nor is there anything else in the record that puts them into dispute.
The George Article offers further insights into what was well known at the time of the claimed invention:
(Mandel Decl., Ex. 43 (dkt. #129-43) 84-85.) In each respect, the George Article supports a conclusion that at the time of the invention, blood testing was the only reliable method to determine whether a patient was complying with a prescribed drug regimen.
Another article that reflects the state of the art is the Haddow Article. Haddow, J., et al., Replacing Creatinine Measurements with Specific Gravity Values to Adjust Urine Cotinine Concentrations, CLINICAL CHEM. 562 (1994). (See Expert Report of Roger L. Bertholf, Ph.D. ("Bertholf Rept."), Ex. H (dkt. #209-8).) The Haddow Article evaluates the use of creatinine and specific gravity values in a study of environmental tobacco smoke exposure in non-smoking children with asthma. (Id. at 562.) Haddow uses a regression analysis
"[A]lthough measuring creatinine measurements to reflect hydration" was known, Haddow teaches that it adds "complexity and cost when such measurements are applied in routine and clinical practice." (Id.) This is why "specific gravity (relative density) measurements in urine samples from children with asthma" were used to "provide information equivalent to that from creatinine measurements." (Id.) Moreover, Haddow does not involve drug treatment or compliance with a prescribed drug regimen and no known normative database is developed. (Id. at 562-64.)
For the purposes of identifying a person of ordinary skill in the art, the court agrees with Dr. Orsulak that the "relevant art of the subject matter claimed by the patents-in-suit is medication or therapeutic drug monitoring." (Orsulak Rebuttal Rept. (dkt. #118) ¶ 3.) Orsulak further opines that such a person would have a degree in a field "such as medicine, biochemistry, biology, clinical health psychology, clinical laboratory sciences, clinical toxicology, or pharmacology and several years of work experience related to medication or therapeutic drug monitoring, including drugs-of-abuse testing or substance abuse testing." (Id.) This characterization of the skilled addressee seems sensible; nothing in Millennium's materials alters this viewpoint; and the characterization is consistent with the field of the art applicable to the invention.
The disputed claims in suit — specifically claims 1, 2, 4-7, 10 and 16-18 of the '680 patent and claims 1, 4-5, 10-12 and 14 of the '895 patent — generally disclose a series of six steps that culminate in a final comparison step between the drug collected from a patient's urine sample to "known normative data" collected from a patient population. Neither party disagrees with this characterization. As such, the asserted independent claims of the '680 patent (claims 1 and 4) and the '895 patent are represented below.
Claim 1 of the '680 patent states:
('680 patent at 21:9-32 (terms in dispute have been bolded).)
Claim 1 of the '895 patent states:
('895 patent at 20:56-21:12.)
With regard to the disputed terms, the parties' preferred constructions are summarized in the following table:
Disputed Terms Plaintiff Ameritox's Preferred Defendant Millennium's Construction Preferred Construction "known normative data" (all Plain and Ordinary Meaning Known dose-specific data that is asserted claims) related to the population it is intended to predict "quantifying the concentration of Plain and Ordinary Meaning To the extent that this term can at least one test metabolite in the be construed, it means: predicting biological sample by comparing a the dosage taken by a patient ratio between the concentration from at least one test metabolite of the test metabolite from the in the biological sample by comparing patient to the set of known normative the ratio based on the data specific to the reference concentration of the test metabolite metabolite concentration" from the patient to the set (all asserted claims) of known normative data specific to the reference metabolite concentration
Millennium contends that the purpose of the patents is to quantify a specific dose. It argues that this purpose provides the proper context and is dispositive of what is meant by "known normative data." Similarly, with respect to the second disputed phrase — "quantifying the concentration" —
Analysis of patent infringement is a two-step process: "first, the scope of the claims are determined as a matter of law, and second, the properly construed claims are compared to the allegedly infringing device to determine, as a matter of fact, whether all of the limitations of at least one claim are present, either literally or by a substantial equivalent, in the accused device." Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1323 (Fed.Cir.2002); Split Pivot, Inc. v. Trek Bicycle Corp., 987 F.Supp.2d 838, 844-47 (W.D.Wis.2013).
Claim terms "are examined through the viewing glass of a person skilled in the art." Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed.Cir.2005). This provides an "objective baseline" from which to begin the claim analysis. Innova/Pure Water, Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1116 (Fed.Cir.2004). The inquiry is assessed at the time of the invention, where the words of a claim "are generally given their ordinary and customary meaning." Phillips, 415 F.3d at 1313.
Because an "ordinary and customary" meaning may not be readily apparent, and because "patentees frequently use terms idiosyncratically," courts look to the patent specification, the prosecution history, and pertinent extrinsic evidence to construe disputed claim terms. Id. at 1314. The specification is typically considered the "best source for discerning the proper context of the claims." Phillips, 415 F.3d at 1315; United States v. Adams, 383 U.S. 39, 49, 86 S.Ct. 708, 15 L.Ed.2d 572 (1966) (describing as "fundamental that claims are to be construed in the light of the specification"). But when using the specification for the purposes of context, the skilled addressee must not improperly import a limitation from the specification into the claims themselves. See Innova, 381 F.3d at 1117 (district court improperly read limitations from the specification into the claims); White v. Dunbar, 119 U.S. 47, 51, 7 S.Ct. 72, 30 L.Ed. 303 (1886).
Claim construction, therefore, requires a scalpel, not a sledgehammer because there is a thin line between interpreting the claims in view of the specification and improperly reading limitations from the specification into the claims. See Innova, 381 F.3d at 1117 (considering the contrasting nature of these axioms to be a "longstanding difficulty"); see also Componex Corp. v. Electronics for Imaging, Inc., No. 13-CV-384-WMC, 2014 WL 3556064, at *7 (W.D.Wis. July 18, 2014).
The term "known normative" data is referenced in element (b) and element (f) of claim 1. (See, e.g., '680 patent at 21:28-32.) The claim language expressly states that known normative data is "collected from a population that is on a prescribed medication regimen." (Id. at 21:16-17.) In the abstract, known normative data is
Millennium contends that the term known normative data is known "dose-specific data that is related to the population it is intended to predict." (Def.'s Opening Br. (dkt. #130) 20.) Millennium contends that its proposed construction is the only one that reflects the express function of the invention. That function, Millennium contends, is to determine the exact dosage taken by a patient (and thereby determining whether a patient is complying with the prescribed dosage). Much of Millennium's construction is based on passages and examples in the specification, with particular emphasis placed on the following passages:
Arguing that these passages reflect the purpose of the patents — "to predict the dosage taken by a patient" — Millennium contends that the claim language should be construed in accordance with that purpose. (Def.'s Opening Br. (dkt. #130) 24.) In addition, Millennium points to Example 1 for support. That example "describes how a drug metabolite/urine creatinine ratio in patients ... could be used to improve the ability of clinicians to predict appropriate use of prescribed medication, as well as detect and quantify inappropriate use." ('680 patent at 6:58:62.) Specifically, Example 1 describes the collection of UDT data from a population of seven patients on "a specified methadone dosing regimen." (Id. at 7:7-8.) Such data is reflected in Table III in each of the patents. Example 1 thus teaches a "regression model for the prediction of methadone intake," namely statistical analysis of "known normative data" to predict the dosage of methadone taken by a patient. (Id. at 9:31-33.) From this, Millennium concludes that because the example is the "only detailed disclosure of the claimed invention in the patents-in-suit," it is instructive and should dictate claim meaning. (Def.'s Opening Br. (dkt. #130) 30.) The court, however, rejects Millennium's construction for several reasons.
To succeed, Millennium ignores a "`bedrock principle' of patent law that `the claims of a patent define the invention.'" Phillips, 415 F.3d at 1312; see also Thorner v. Sony Computer Entm't Am. LLC, 669 F.3d 1362, 1365 (Fed.Cir.2012). Millennium also faces an uphill battle in negating the general rule that claims are given their customary and ordinary meaning. See Teleflex, Inc. v. 299 F.3d at 1325 ("We indulge a `heavy presumption' that a claim term carries its ordinary and customary meaning."). Specifically, courts should "only interpret a claim term more narrowly than its ordinary meaning under two circumstances: (1) when a patentee sets out a definition and acts as [its] own lexicographer, or (2) when the patentee disavows the full scope of a claim term either in the specification or during prosecution history." Aventis Pharma SA v. Hospira, Inc., 675 F.3d 1324, 1330 (Fed. Cir.2012) (internal quotation omitted). "The standards for finding lexicography and disavowal are exacting." Hill-Rom Servs., Inc. v. Stryker Corp., 755 F.3d 1367, 1371 (Fed.Cir.2014) (emphasis added). Neither of these circumstances applies
First, Millennium points to no definitive definition of "known normative data" in the specification that supports its construction. When the skilled addressee turns to the specification the only definition that even comes close to the disputed phrase is the phrase: "normative database." ('680 patent at 5:60-65.) Notwithstanding the fact that "normative database" is worded differently to "known normative data" (the disputed term), Millennium's reliance on the former falls flat because the definition of "normative database" simply states "a collected set of data that is related to a specific population it is intended to predict." (Id. at 5:58-60.) Contrary to Millennium's position, there is no mention of dose specific data or dose specific regimen. Because none of the definitions in the specification supply claim meaning, Millennium's proposed construction must be rejected. See Hospira, Inc., 675 F.3d at 1330; Aria Diagnostics, Inc. v. Sequenom, Inc., 726 F.3d 1296, 1301 (Fed.Cir.2013) ("Taken in context, this evidence does not support the trial court's interpretation, and certainly is not clear lexicography or disavowal.").
Second, there is no claim disavowal in the prosecution history. The best that Millennium can muster is the following passage:
(Def.'s Opening Br. (dkt. #130) 29 (emphasis altered).) Millennium's reliance on this passage is deficient for much the same reason as the first: the term normative database is used instead of the actual disputed term that is subject to the litigation (i.e., known normative data). But even if the proper disputed phrase had been referenced above, the passage still supplies little to support Millennium's position. Indeed, the passage creates more questions than answers due to the permissive language used. Said another way, the word "may" preceded by the phrase "manner consistent with the prescription" is hardly verbiage that disavows the full scope of a claim term. Neither phrase is "exacting." Stryker Corp., 755 F.3d at 1371. While Millennium argues that a person skilled in the art would equate the phrase "manner consistent with prescription" as meaning dose specific data, the court is not so convinced. Id. at 1372 ("Disavowal requires that the specification or prosecution history make clear that the invention does not include a particular feature.").
Third, Millennium provides no meaningful discussion for how references in the specification and the prosecution history narrowed claims scope to circumvent prior art. More specifically, nothing in the specification indicates that "dose specific data" is an essential feature of the claimed invention over the prior art. See Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 906-09 (Fed.Cir.2004) (distinguishing cases where the court narrowly construed an otherwise broad claim term).
To be fair, Millennium does argue that:
Here, no effort is made by Millennium to show that the inventors deliberately abandoned claim scope to traverse prior art, let alone refer to the specific prior art references that inventors were seeking to distinguish in the prosecution history to provide a basis for estoppel. Without such analysis, Millennium's construction is far less persuasive. It is rejected accordingly. Cf. Spectrum Int'l, Inc. v. Sterilite Corp., 164 F.3d 1372, 1379-80 (Fed.Cir.1998) ("By distinguishing the claimed invention over the prior art, an applicant is indicating what the claims do not cover.").
Fourth, Millennium's argument fares no better when it points to examples in the specification to construe the claims. Specifically, Millennium argues that known normative data must mean "dose specific" data because Example 1 expressly supplies such meaning when read in the context of both patents. To succeed in this argument, Millennium must again overcome the presumption that favors plain and ordinary meanings of claim terms. In Teleflex, the Federal Circuit held that the district court erred when it imported a limitation from the specification, thereby straying from the ordinary meaning of the claim term "clip" by requiring a "clip" to have a "single pair of legs," even though the only embodiment in the specification disclosed a clip having a single pair of legs. 299 F.3d at 1327-28 (emphasis added). Thus, in Teleflex, the only embodiment in the specification supported the alleged infringer's position — and the Federal Circuit still reversed.
Unlike Teleflex, multiple embodiments are provided in the '680 and '895 patents. Although Example 1 does provide a dose specific embodiment, other embodiments are not so confined. Ameritox directed the court to the following passage from the specification that is illustrative:
('680 patent at 3:6-18 (emphasis added).)
Even if all the embodiments described known normative data as including dose-specific data (and they do not), Millennium's construction would still stray impermissibly from the plain and ordinary meaning of the claim term. Teleflex states as much. 299 F.3d at 1325; see also Aria Diagnostics, Inc. v. Sequenom, Inc., 726 F.3d 1296, 1301 (Fed.Cir.2013) ("[E]ven if a specification has only one embodiment,
As the passage explains, the use of the phrase known normative data is deliberately juxtaposed with unknown data from the test metabolite. The juxtaposition is used to demonstrate that while the invention does require known normative data to provide a baseline from which to improve clinical urine testing, that data need not be a specific dosage. Indeed, had the patentee sought to limit the claim language in this way, it would have elected to do so. The lack of a limitation in the claims reinforces the case against a restrictive reading of the disputed term. See ACTV Inc. v. Walt Disney Co., 346 F.3d 1082, 1088 (Fed.Cir.2003) ("[T]he analytical focus of claim construction must begin, and remain centered, on the language of the claims themselves.").
More specifically, element (b) of claim one expressly states: "providing one set of known normative data specific to a reference metabolite, wherein the set of data is collected from a population that is on a prescribed medication regimen." ('680 patent at 21:16-17 (emphasis added).) Language in the embodiment above tracks key language in claim 1 of the '680 patent as demonstrated here, only strengthening Ameritox's construction-i.e., data that is not unknown, and certainly not limited to data that is dose specific. The view is fortified by the fact that when inventors knew how to specify dose in one of the patents' embodiments (Example 1), they did so. And by not doing the same in the claims, this tends to end the debate over the disputed term. (Compare '680 patent at 9:65-66 (specification using the term "prescribed dosage regimen"), with id. at 21:16-1 (claim 1 using the phrase "prescribed medication regimen").)
Accordingly, because of the claim language conforms with embodiments cited in the specification and because there is no clear scope disavowal, the court rejects Millennium's proposed construction.
Millennium argues that interpretation of step (f) is guided by the "intended purpose of the patents," which is "to predict or determine drug dosage taken by a patient." (Def.'s Opening Br. (dkt. #130) 44.) It follows, Millennium contends, "that any construction of the claim — specifically step (f)'s comparison between the patient's ratio to the known normative data from a population — must reflect the stated goal." (Id. at 45.) The court disagrees.
As an initial matter, the purpose of the patents is far broader than what Millennium maintains. Millennium's entire construction is predicated on the flawed assumption that that the patents' sole objective is to identify the specific dose of a patient.
When compared with pre-existing testing protocols, the state of the art sought to determine "a positive or negative result as to the presence or absence" of a drug. (Id. at 2:66-67.) In contrast, the '680 patent provides a method to "improve" and "enhance" medication monitoring and identify aberrant drug use. (Id. at 3:17-19.) While Millennium is correct in saying that courts look to the object or purpose of the invention, such analysis must be examined in the totality so to guard against the claims being pulled in different ways by the different embodiments in the specification. See White, 119 U.S. at 51-52, 7 S.Ct. 72 (patents are not "nose[s] of wax which may be turned and twisted in any direction by merely referring to the specification").
Millennium further contends that each of the examples indicate specific embodiments of the invention that seek to predict dosage based on the comparison applied in step (f). For reasons similar to that stated above, this argument must also be rejected. Two aspects of the claimed invention include: (1) "determine if the medication is utilized in a manner consistent with the prescription" and (2) "determine ... what the [patient's] potential dose may have been." (Mandel Decl., Ex. 24 (dkt. # 129-24) pp. 14-15; see also '680 patent at 3:20-27.) The first aspect can be accomplished with or without definitive prediction of dosage. While the second aspect uses dose-specific data, the patent stops short of claiming that the invention definitively predict ingested dose, simply stating that the invention may be used to approximate what the "potential" dose "may have been." The multiple aspects of the patent demonstrate that the asserted claims do not require dose-specific data. As such, the asserted patents are prime examples for why the Federal Circuit "repeatedly warn[s] against confining the claims to [the] embodiments" of the specification. Phillips, 415 F.3d at 1323; see also Teleflex, 299 F.3d at 1325.
Claim language that is narrow would only limit the patents to determining potential or approximate doses, not whether medication is being used in a manner consistent with the prescription. The claim encompasses both these embodiments. A broader purpose afforded to the patented invention reflected in the actual claim language ensures a plurality of embodiments that fall within the claims. This broad reading of the claims is further fortified by the fact that the word "dose" and "dose-prediction" appear nowhere in the asserted claims. Like the previous disputed term, the lack of a limitation in the claims reinforces the case against a restrictive reading of the disputed term here. See ACTV, 346 F.3d at 1088 ("[T]he analytical focus of claim construction must begin, and remain centered, on the language of the claims themselves.").
Accordingly, Millennium's request that the court read a definitive dose-prediction limitation into the asserted claims finds no
Summary judgment is warranted under Federal Rule of Civil Procedure 56 "if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law." Fed.R.Civ.P. 56(a). The moving party bears the burden of showing that the facts material to the motion are not in dispute. Celotex Corp. v. Catrett, 477 U.S. 317, 323, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). The nonmoving party may not avoid summary judgment merely by showing that some facts are in dispute; rather, it must establish that there are factual issues that might affect the outcome of the suit under governing law. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247-48, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). Although the court must "take all facts and reasonable inferences in the light most favorable to" the nonmoving party, Helman v. Duhaime, 742 F.3d 760, 761 (7th Cir.2014), the nonmoving party must still come forth with enough evidence to support a reasonable jury verdict in its favor, Delta Consulting Grp., Inc. v. R. Randle Constr., Inc., 554 F.3d 1133, 1137 (7th Cir.2009). Summary judgment is "not a dress rehearsal or practice run," but the "put up or shut up moment" in which a party must show what evidence it has to convince a trier of fact to accept its version of events. Nichols v. Nat'l Union Fire Ins. Co. of Pittsburgh, PA, 509 F.Supp.2d 752, 760 (W.D.Wis.2007) (quoting Schacht v. Wis. Dep't of Corr., 175 F.3d 497, 504 (7th Cir.1999)).
Because a patent is presumed valid, Millennium must prove invalidity by clear and convincing evidence. See Microsoft Corp. v. i4i Ltd. P'ship, ___ U.S. ___, 131 S.Ct. 2238, 2242, 180 L.Ed.2d 131 (2011). Thus, for Millennium to succeed in the instant motion for summary judgment, it must present clear and convincing evidence from which a reasonable jury could find that the patent is invalid. See Nystrom v. TREX Co., 424 F.3d 1136, 1149 (Fed.Cir.2005); see also CertusView Techs., LLC v. S & N Locating Servs., LLC, No. 2:13cv346, 2015 WL 269427, at *14 (E.D.Va. Jan. 21, 2015).
Section 101 of the Patent Act defines patentable subject matter: "Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title." 35 U.S.C. § 101. The section defines four categories of patentable inventions: processes, machines, manufactures, and compositions of matter. Despite these broad categories, § 101 does not encompass all products of human effort and discovery. For example, "laws of
The validity of many business and software patents has been called into question following the Supreme Court's decision in Alice Corporation v. CLS Bank International, ___ U.S. ___, 134 S.Ct. 2347, 189 L.Ed.2d 296 (2014).
In Alice, the Supreme Court articulated a "framework" for determining whether 35 U.S.C. § 101 is met. 134 S.Ct. at 2355 (citing Mayo, 132 S.Ct. at 1296-97). First, a court determines "whether the claims at issue are directed to one of those patentineligible concepts" — i.e., whether the claims are directed to laws of nature, natural phenomena, and abstract ideas. Id. Second, if the claims are directed to patent-ineligible concepts, the process sought to be patented must include an additional element or a combination of additional elements that constitute "inventive concept'" — i.e., "an element or combination of elements that is `sufficient to ensure that the patent in practice amounts to significantly more than a patent upon the [ineligible concept] itself.'" Alice, 134 S.Ct. at 2355 (quoting Mayo, 132 S.Ct. at 1294); see also Funk Bros., 333 U.S. at 130, 68 S.Ct. 440 ("If there is to be invention from [a discovery of a law of nature], it must come from the application of the law of nature to a new and useful end.").
Before applying the Alice framework to the patents-in-suit, a review of the Supreme Court's recent decisions in Mayo, which similarly dealt with drug level testing and diagnostic patents, as well as some of the post-Alice Federal Circuit decisions
The Supreme Court found that this is where the patent addressed a need, with claims directed to "processes embodying researchers' findings that identified these correlations with some precision."
To begin, the Supreme Court held that the "administering" step did not supply inventive concept because the "step simply refers to the relevant audience, namely doctors who treat patients with certain diseases with thiopurine drugs." Id. The "determining" step was treated with equal disdain because it simply "tells the doctor to determine the level of relevant metabolites in the blood, through whatever process the doctor ... wishes to use." Id. Justice Breyer found that step "nothing more [than] well-understood, routine, conventional activity previously engaged in by scientists who work in the field." Id. To support this conclusion, Justice Breyer cited admissions in the patent itself that the processes for determining the level of metabolites in a patient's blood were "well known in the art." Id. at 1298.
Next, the Court addressed the patentability of the combination of these steps. The Court found that "to consider the three steps as an ordered combination adds nothing to the laws of nature that is not already present when the steps are considered separately." Id. Justice Breyer's opinion distinguished the decision from the Court's previous holding in Diamond v. Diehr, 450 U.S. 175, 101 S.Ct. 1048, 67 L.Ed.2d 155 (1981). To Justice Breyer, nothing in Diehr suggests that the steps of the claimed process or their combination "were in context obvious, already in use, or purely conventional," as had been found to be true with respect to the claimed process in Parker v. Flook, 437 U.S. 584, 98 S.Ct. 2522, 57 L.Ed.2d 451 (1978).
Finally, Justice Breyer expressly addressed the risk of preemption, stating that "the Court has repeatedly emphasized the concern that patent law [must] not inhibit further discovery by improperly tying up the future use of laws of nature." Mayo, 132 S.Ct. at 1301. For this reason, Justice Breyer cautioned against patents that would "foreclose[] more future invention than the underlying discovery could reasonably justify." Id.
Since Mayo and Alice, the Federal Circuit has continued to develop the standard for what constitutes patentable subject matter. In particular, two recent decisions provide insights into what constitutes an "inventive concept" under Alice's second step. In DDR Holdings, LLC v. Hotels.com, L.P., 773 F.3d 1245 (Fed.Cir. 2014), for example, the Federal Circuit
More recently, the Federal Circuit examined whether gene sequences known as BRCA1 and BRCA2 could overcome a § 101 challenge. In re BRCA1- & BRCA2-Based Hereditary Cancer Test Patent Litig., 774 F.3d 755 (Fed.Cir.2014). The case involved Myriad Genetics, Inc. suing Ambry Genetics Corporation for infringement of U.S. Patent No. 5,753,441 and U.S. Patent No. 5,747,282. In the 1990s, Myriad had discovered the precise locations and sequences of the BRCA1 and BRCA2 genes, mutations linked to hereditary breast and ovarian cancers. Myriad was then able to determine the typical sequences of the genes most often found in humans (i.e., the "wild-type" sequence for each), as well as mutations that depart from these two sequences. Some mutations were harmless, while other mutations correlated with an increased likelihood of developing particular cancers. By testing for the presence of these mutations, doctors could determine whether a patient is particularly prone to developing breast or ovarian cancer.
As in the present case, the method claims involved comparison steps. Ambry, however, argued that Mayo was directly on point because these claims "simply identif[ied] a law of nature (the precise sequence of the BRCA genes, and comparisons of wild-type BRCA sequences with certain mutations of those gene sequences found in the test subject) and appl[ied] conventional techniques." Id. at 762. In a slight twist, the Federal Circuit declined to decide whether Mayo applied to the process patents "because the method claims suffer[ed] from a separate infirmity: they recite[d] abstract ideas." Id. In analyzing claims 7 and 8, the court noted that both were similar and dependent from claim 1. In applying the two-step framework of Alice, the court dissected the claims to a first set of paragraphs, "which describe the comparison of wild type genetic sequences with the subject's genetic sequence and correspond to the first step of Alice" and the second set of paragraphs, "which describe the techniques to be used in making the comparisons and correspond to the second step of Alice." Id. at 763.
Holding that the first paragraphs — the comparison step — amounted to an abstract idea, the court turned to the second paragraphs in claim 7 and claim 8, respectively. Id. The court found that the second paragraph of claim 7 described the way in which the "sequences are compared: they are compared by 1) hybridizing a BRCA gene probe and 2) detecting the presence of a hybridization product." Id. at 764. Similarly, the court said that "claim 8 requires 1) amplification of the BRCA1 gene
Id. (emphasis added).
Just as Justice Breyer tethered the notion of well-understood, conventional steps to "activity already engaged in by the scientific community" in Mayo, 132 S.Ct. at 1298, the Federal Circuit in BRCA1 tethered the notion of well-understood, conventional steps to "techniques that a scientist would have thought" to use when deciding to engage in experiments that were directed to the invention, 774 F.3d at 764 (emphasis added). Both of these articulations amount to the same concept: whether the scientific community would have thought to do something at the time of invention is very much dependent on what activities scientists had already been engaged in at the time.
Of course, the inverse concept also is true: if inventors engage in activities that run counter to scientific thought, those activities can hardly be considered conventional under § 101. This latter concept would similarly apply when a patent involves a combination of elements that the scientific community would not have thought to use or implement to deliver a new, improved and useful result. 35 U.S.C. § 100 ("The term `process' means process, art or method, and includes a new use of a known process."). Indeed, the new and useful result of a combination patent resides precisely in a combination that neither existed in the prior art, nor was the possibility of such a combination well known in the art at the time of the invention.
When invention is based on the combination of elements that cuts against the grain of scientific thought, this heightens the novelty of invention itself.
While not expressly referenced in the Alice framework, an underlying concern is general preemption. That concern was underscored in Mayo. As previously discussed, what lies at the core of preemption is the question of whether the patent "forecloses more future invention than the underlying discovery could reasonably justify."
To satisfy the framework laid out in Alice, therefore, the invention must "supply a "`new and useful'" application of the idea in order to be patent eligible." Alice, 134 S.Ct. at 2357; see also Le Roy v. Tatham, 55 U.S. 156, 159, 14 How. 156, 14 L.Ed. 367 (1852) ("There can be no doubt that, if this combination is new, and produces a new and useful result, it is the proper subject of a patent. The result is a new manufacture. And even if the mere combination of machinery in the abstract is not new, still, if used and applied in connection with the practical development of a principle, newly discovered, producing a new and useful result, the subject is patentable.").
In what amounts to a conspiracy of silence, while Millennium challenges both the '680 patent and the '895 patent under § 101, both parties focus their § 101 analysis narrowly on the more tailored '680 patent, likely because Millennium must prevail in its challenge with respect to both and plaintiffs are happy to argue § 101 using the stronger of its two patents. Because
At step one, the court determines "whether the claims at issue are directed to ineligible subject matter." Alice, 134 S.Ct. at 2355. Millennium argues that the claims as a whole are directed to an abstract idea, but places particular emphasis on element (b) and element (f) of claim 1 and the related claims. The latter recites a comparison "of a person's metabolite/creatinine ratio to `known normative data' (a population of metabolite/creatinine ratios)." (Def.'s Opening Br. (dkt. # 130) 63-64.) Ameritox counters by pitching the invention at a more specific level, arguing that the claims are directed "to quantifying a metabolite concentration by adjusting the concentration for the patient's hydration status and then statistically comparing the adjusted concentration to a set of known normative data."
The court finds Millennium's position more persuasive. While the skilled addressee would view comparative analysis of the invention as one that seeks to achieve a new and useful result over prior urine screening protocols, this new and useful result still rests upon an abstract idea, at least at some level. This finding is consistent with the recent BRCA1- decision, which also involved method claims. Specifically, the claims identified "a law of nature ([i.e.] the precise sequence of BRCA genes and comparisons of wild-type BRCA sequences with certain mutations of those genes found in the test subject) and applied conventional techniques" to determine a patient's propensity to cancer. See BRCA1-, 774 F.3d at 761. In finding in favor of the defendant, the BRCA1- court held that the comparative analysis of the invention "recite[d] abstract ideas." Id. at 762.
Because the present case involves a comparative analysis like that found in BRCA1, Millennium satisfies step one of the Alice framework. Id.; see also Bilski, v. Kappos, 561 U.S. 593, 611-12, 130 S.Ct. 3218, 177 L.Ed.2d 792 (2010) (characterizing abstract idea as "the concept of hedging" where claim limitations described initiating transactions and identifying market participants); Alice, 134 S.Ct. at 2356 (characterizing abstract concept as "intermediated settlement" despite claim elements reciting use of shadow credit records and debit records); buySAFE Inc. v. Google, Inc., 765 F.3d 1350, 1354-55 (Fed. Cir.2014) (holding that "[t]he claims are squarely about creating a contractual relationship" despite presence of more specific claim limitations); Ultramercial, 772 F.3d at 715 (holding that "the concept embodied by the majority of the limitations describes only the abstract idea of showing an advertisement before delivering free content" despite presence of other limitations).
But as Millennium must readily acknowledge and as previously discussed, it would be a rare case where a patent is not directed to ineligible subject matter under § 101. See Mayo, 132 S.Ct. at 1293 ("[A]ll inventions, at some level ... apply laws of nature, natural phenomena or abstract ideas."); cf. AutoForm Eng'g GMBH v. Eng'g Tech. Assocs., Inc., No. 10-14141, 2014 WL 4385855, at *3-4 (E.D.Mich. Sept. 5, 2014); Ameranth, Inc. v. Genesis Gaming Solutions, Inc., No. 11-00189, 2014 WL 7012391, at *6 (C.D.Cal. Nov. 12, 2014) (explaining that the cotton gin could
Holding that the claims are directed to an abstract idea, however, does not win the day for Millennium. As noted at the outset, an invention is not rendered ineligible simply because it involves an abstract idea. Applications of concepts "to a new and useful end" remain eligible for patent protection. Alice, 134 S.Ct. at 2354 (quoting Benson, 409 U.S. at 67, 93 S.Ct. 253). To meet this second step under Alice, claims directed to an abstract idea must contain an "inventive concept," that is "an element or combination of elements that is sufficient to ensure that the patent in practice amounts to significantly more than a patent upon the [ineligible concept] itself." Id. at 2355 (emphasis added).
Claim 1 of the '680 patent states:
('680 patent at 21:9-32.) For ease of reference, elements (a)-(d) will be described as the "detection" steps. Element (e) will be described as the "normalization" step. Element (f) will be described as the "comparative" step.
Millennium argues that the claims are conventional because they "direct medical professionals to measure the level of a drug metabolite, to normalize data via a creatinine ratio, and then to compare that value against the creatinine ratios of a population of individuals." (Def.'s Opening Br. (dkt. # 130) 78.) Millennium further argues that because these elements are conventional, the invention lacks an "inventive concept" beyond the abstract idea itself.
Ameritox's position is more nuanced. Ameritox argues that the claim elements are unconventional because the asserted claims are drawn to specific methods of monitoring medication through normalization and quantification of metabolites in a urine sample. Ameritox contends that these steps contain an inventive concept because the process described seeks to implement a novel solution to a pre-existing problem in the field. (Pl.'s Opp'n (dkt. # 172) 99.) Indeed, much of Ameritox's
First, when the invention is examined as an ordered combination, the combination of steps produces a new and useful result. 35 U.S.C. § 101 (the patent statute provides protection for "any new and useful process"). The instant case shares similarities with Diehr in this respect. In both cases, the subject patents are directed to abstract ideas that improve pre-existing technology. Specifically, like the rubber curing improvements taught in the Diehr patent, new improvements are similarly taught in the '680 patent (albeit with respect to drug compliance monitoring). Indeed, each additional step taught directs the skilled addressee to an invention that allows quantifiable analysis of urine samples to determine a patient's compliance with a prescribed drug regimen. This type of improvement in existing technology is the type of invention that the statute seeks to encourage, not dismiss. 450 U.S. at 183, 101 S.Ct. 1048; see also Alice, 134 S.Ct. at 2359 (looking at improvements in the "functioning" of a computer and the "technical field"); Bilski, 561 U.S. at 601, 130 S.Ct. 3218 ("Congress took this permissive approach to patent eligibility to ensure that ingenuity should receive a liberal encouragement.") (internal quotation marks omitted).
In DDR, Judge Chen similarly upheld under § 101 scrutiny, an invention that addressed the challenge of retaining website visitors that was specific to the internet, as opposed to the "performance of a business practice known prior to the `pre-internet world.'" DDR, 773 F.3d at 1257. Although the patent claimed a solution "rooted in computer technology," Judge Chen found the hybrid functionality of the invention constituted inventive concept. Id. This holding was reinforced by the fact that the claims addressed the problem of retaining website visitors otherwise instantly transported away from a website after "clicking" on an advertisement. Id. While the invention at issue in DDR was in the software field, that decision establishes that inventive concept can be established by something more than "conventional functioning" that targets and improves existing technological processes for a specific problem in field of the invention. Id.; see also Wavetronix LLC v. Iteris, Inc., No. A-14-CA-970-SS, 2015 WL 300726, at *6 (W.D.Tex. Jan. 22, 2015) (citing Alice, 134 S.Ct. at 2358).
Here, the '680 specification states that previous urine protocols were restricted in their application because they could only test for positive or negative results as to the "presence or absence of a drug metabolite in urine." ('680 patent at 2:64-67.) This problem was described as a "major difficulty" in the art because of the "large amount of variance in urine drug concentrations, mostly due to variations in hydration and urinary output volume." ('680 patent at 1:51-52.) In addressing the problem, the inventors coupled the normalization step with the comparative step, allowing for more accurate assessment of aberrant drug use. Nothing in Millennium's summary judgment materials rebuts what was plainly identified on the face of the specification as a problem in the field, nor directly rebuts the solution that the patent provided. This is telling.
Second, Millennium's analysis of the second Alice step to the '680 patent is flawed. As an initial matter, Millennium argues that the comparative step must be filtered out of the analysis when looking at a combination patent, because it is either a "known method" or "an unpatentable ... process." (Def.'s Opening Br. (dkt. # 130) 78.) But there is nothing in Alice suggesting that any steps are "filtered out" when considering a combination patent. To the contrary, the invention in Alice was considered as "a whole" when assessing the second step of the framework. 134 S.Ct. at 2359 ("Considered as an ordered combination [and] ... [v]iewed as a whole, petitioner's method claims simply recite the concept of intermediated settlement as performed by a generic computer." (internal quotations omitted, emphasis added)).
Alternatively, Millennium argues that instead of ignoring the comparative step, the detection and normalization steps must be discounted because they exist in the prior art, leaving only an abstract idea at the comparative step. (Def.'s Opening Br. (dkt. # 130) 78.) Essentially, Millennium appears to assert that any additional steps beyond the abstract idea do not elevate the claim to "inventive concept," because each step was either "established" or "conventional." (Id.) Not so under Alice.
Specifically, looking at the normalization step, Millennium merely relies on its proposed finding that: "Normalizing urine samples [had] been routine and conventional practice for over 40 years." (Dr. Alan H. Wu Invalidity Report ("Wu Invalidity Rept.") (dkt. # 115) ¶ 112.) To support this proposed finding, Millennium infers that because creatinine normalization was mentioned in the George article, someone skilled in the art would know to simply combine the normalization step with the detection and comparative steps. Millennium argues that this finding is also supported by Dr. Wu, who opined that for § 101 purposes, "neither the individual claim steps of the patented methods nor the series of claim steps in the patented methods are novel." (Id.)
In reviewing the experts' reports, however, there is nothing that supports a finding that the combination of the steps is routine and conventional.
When looking at a combination patent, what courts most want to know is: who would have thought to combine the known elements in the first place and why?
Third, and a close corollary of the second, evidence of combination helps to guard against hindsight bias. To ignore this concern would provide a `blank check' to all those who challenge patents without sufficient legal or evidentiary basis. Given that Alice now expressly requires that courts look at patented elements in combination when assessing inventive concept (as did Mayo), the concern of hindsight bias has as much relevance to a § 101 challenge as it does a § 103 challenge. See generally Mayo, 132 S.Ct. at 1299 ("at least the combination of those steps, were in context obvious, already in use, or purely conventional"). Where, as here, § 101 is effectively being used as a de facto § 103 challenge, some rational basis for combination must be proffered, particularly in a case like this where the patent has survived prosecution and two further rounds of re-examination, as plaintiffs point out (repeatedly) in briefing. See KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 417-18, 127 S.Ct. 1727, 167 L.Ed.2d 705 (2007) (noting the need to "be cautious of arguments reliant upon ex post reasoning"); Scientific Plastic Prods., Inc. v. Biotage AB, 766 F.3d 1355, 1362-63 (Fed. Cir.2014) (Moore, J., dissenting); W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540, 1553 (Fed.Cir.1983) ("To imbue one of ordinary skill in the art with knowledge of the invention in suit, when no prior art reference or references of record convey or suggest that knowledge, is to fall victim to the insidious effect of a hindsight syndrome wherein that which only the inventor taught is used against its teacher.").
Finally, having had the benefit of claims construction and viewing the claims through the lens of the skilled addressee, the court is well versed in the state of the art at the time of the invention. In many
Here, Millennium can point to no reference demonstrating the existence of or even suggesting the combination of the comparative step with the additional steps of the invention. And there is certainly nothing in the art that demonstrates that such a combination was well-known. This provides indicia that the '680 patent is inventive for § 101 purposes. See Mayo, 132 S.Ct. at 1297-99. Indeed, in Mayo, Justice Breyer explained that the invention in Diehr was patentable because the "ordered combination" of the steps of the claimed invention were "nowhere suggested" to be "in context obvious, already in use, or purely conventional." Id. at 1299; see also Oleksy v. Gen. Elec. Co., No. 06-C-01245, 2013 WL 3233259, at *5 (N.D.Ill. June 26, 2013) ("Oleksy's process is patentable despite its reliance on mathematical equation because of the way the equation is integrated into a process that also uses steps that are not obvious, already in use or purely conventional"); France Telecom S.A. v. Marvel Semiconductor Inc., 39 F.Supp.3d 1080, 1093, 2014 WL 1478850, at *8-9 (N.D.Cal.2014) (finding the claims are "narrow and they confine and tie down the otherwise abstract processes cited" and provide "`inventive concepts' that exceed the prior art, namely coding in parallel and a novel method of iterative coding").
Moreover, Millennium has failed to offer any evidence that someone in the scientific community would have even "thought" to combine the claimed elements. BRCA1, 774 F.3d at 764. For § 101 purposes, this makes the claims new and useful over the prior art. Id.; see also Diehr, 450 U.S. at 188, 101 S.Ct. 1048 ("[A] new combination of steps in a process may be patentable even though all the constituents of the combination were well known and in common use before the combination was made."); Ultramercial, 772 F.3d at 715 ("[A]ny novelty in implementation of the idea is a factor to be considered only in the second step of the Alice analysis." (emphasis added)); Parks v. Booth, 102 U.S. 96, 102, 26 L.Ed. 54 (1880).
As stated previously, the George Article is indicative of routine and well-known techniques at the time of the invention in the urine testing world. Not only was it frequently cited in the prosecution history, but both parties' experts rely upon the article for purposes of §§ 101, 102 and 103, and Millennium expressly put the article into evidence to support its position on § 101. The article also predated the invention by four years, making it indisputably well known before the patent's filing date. The purpose of the study as described in the George Article was to find a noninvasive way of testing for drug compliance.
If the seminal reference in the art at the time stated that blood sampling was by far preferable to urine normalization, because of the latter's unreliability, why would anyone in the industry have thought to use a normalization step for urine in drug protocols? Cf. BRCA1, 774 F.3d at 764 (addressing what a "scientist would have thought of" with respect to gene sequences). Regardless, a normalization step that others skilled in the art had rejected as unreliable can hardly be considered conventional in the § 101 context.
Because the inventors cut against scientific thought at the time of the invention, and because the invention targeted a specific problem in the field of urine testing, the court finds that there is sufficient inventive concept in the '680 patent for the purposes of meeting the threshold test of section 101. BRCA1-, 774 F.3d at 764; Ultramercial, 772 F.3d at 715.
While each of the reasons above address Millennium's section 101 challenge in isolation, Millennium also fails to proffer any meaningful evidence to support a finding of preemption for the '680 patent. See Helios Software, LLC v. SpectorSoft Corp., No. 12-081-LPS, 2014 WL 4796111, at *17 (D.Del. Sept. 18, 2014) (finding that because defendant "provided no support" the court could not find "that the patents-in-suit were drawn to [eligible subject matter]"). This further suggests that the limitations in the '680 patent do not have preemptive effect, something reinforced by
None of this can be said with respect to the '895 patent. On the contrary, the sweeping claim to "a method for quantifying at least one metabolite in at least one biological sample" refers to nothing more than the claimed discovery of a method for "quantifying the concentration of at least one test metabolite in the biological sample" against an unspecified and undisclosed "known normative data specific to the reference metabolic concentration." Unlike element (e) of the claims in the '680 patent, there is no teaching against the art well-known at the time with respect to the use of creatinine concentration in urine, no specification of a similar test metabolite in other biological samples, or unique relationships between at least one biological sample obtained from a patient and a set of known normative data specific to the referenced metabolite concentration. In short, the '895 patent merely deletes the limitation of the biological sample of urine leaving a sweeping claim to biological samples consisting of "blood, salvia, sweat, spinal and brain fluids." ('895 patent at 4:58-60.) Not only does the patent not provide enablement for biological samples other than urine under § 112 for reasons discussed below, but it amounts to nothing more than speculative claims that purport to preempt similar discoveries with respect to other biological samples. This would appear exactly the kind of preemption strongly disfavored by the United States Supreme Court because it "forecloses more future invention than the underlying discovery could reasonably justify." Mayo, 132 S.Ct. at 1301; see also Lemley, supra note 20, at 1329-30 ("The abstract ideas exception should disallow those claims to ideas unmoored to real-world applications, taking into account the extent to which the claim forecloses after-arising embodiment of the idea, the nature and extent of the prior art, and the level of disclosure by the inventor.").
Indeed, as detailed already, it is the very combination of integers in the '680 patent that supplies the inventive concept to that invention. By stark contrast, the '895 patent makes one of those elements redundant — namely element (e) — effectively seeking to broaden that patent because there is one less limitation that must be met when seeking infringement with respect to, for e.g., blood. Said another way, and to draw an analogy with a mechanical patent, element (e) provides a pivot point between the detection steps ((a) — (d)) and the comparative step (f) that is essential to invention described in the '680 patent. Rendering that pivot point irrelevant to the combination of the '895 patent — for example, because blood does not require creatinine-normalization — cuts away from the novelty and inventiveness of the patent itself, which in turn, cuts away from any justification for allowing the broad claim scope of the '895 patent. Mayo, 132 S.Ct. at 1301. Accordingly, without restriction to urine screening, the claims in the '895 patent are invalid under § 101, and for reasons that are foreshadowed here, invalid under § 112(a).
Regardless of the court's conclusions on claim construction and § 101, Millennium argues that the patents-in-suit are invalid under § 112. Specifically, Millennium argues that the claims of both patents are invalid under the doctrines of indefiniteness and enablement. Since both patents share the same specification, the court addressed the patents together, just as Millennium did in briefing.
Because the court has earlier found that the claims can be construed by a person having ordinary skill in the art, much of Millennium's indefiniteness argument falls flat, but the court will briefly address why, beginning with § 112 itself. Paragraph 2 of § 112 provides that a patent's specification must "conclude with one or more claims particularly pointing out and distinctly claiming the subject matter [that] the applicant regards as [the] invention." 35 U.S.C. § 112, ¶¶ 2. In Nautilus, Inc. v. Biosig Instruments, Inc., ___ U.S. ___, 134 S.Ct. 2120, 189 L.Ed.2d 37 (2014), the Supreme Court recently explained that under § 112, ¶ 2, "a patent's claims, viewed in light of the specification and prosecution history, [need only] inform those skilled in the art about the scope of the invention with reasonable certainty." Id. at 2129 (emphasis added). The Supreme Court further explained in Nautilus that indefiniteness requires a "delicate" balance:
Id. at 2128-29 (internal citations and quotation marks omitted). Accordingly, the definiteness requirement "mandates clarity," while recognizing that absolute precision is "unattainable." Id. at 2129.
Here, Millennium primarily challenges the validity of Ameritox's construction of a term in element (f) of each of the independent claims in the patents-in-suit — "quantifying the concentration." Millennium argues that under this now adopted construction, the independent claims are all rendered indefinite. Under § 112 ¶ 2, however, Millennium must provide clear and convincing evidence that the claims fail to provide reasonable certainty as to the scope of the patent. Microsoft Corp. v. i4i Ltd. P'ship, ___ U.S. ___, 131 S.Ct. 2238, 2242, 180 L.Ed.2d 131 (2011). That threshold has not been satisfied here, particularly in light of what is stated in the specification and the prosecution history.
With respect to the former, Example 1 provides a detailed summary of the invention, which is cross-referenced to Figure 4. The example explains how the claimed invention will "improve the ability of clinicians to predict appropriate use of prescribed medication" and "detect and quantify inappropriate use." ('680 patent at 6:58-62.) The inventors further teach how this is achieved with respect to element (f) via statistical analysis of normative data establishing "95% prediction intervals" to identify aberrant medication. (Id. at 6:30-35.) That data, as the specification suggests, can then be translated into prediction limits, which are depicted in Figure 4 of the patent:
('680 patent at FIG. 4.) The circles represent normative data. The black squares reflect "known outliers" or "aberrant results." The graph demonstrates that quantifying a urine sample quickly identifies instances of nonadherence. (Id. at 4:6-10; see also id. at 11:1112 ("The data used in this study was sufficient to yield a highly significant regression analysis that allowed the demonstration of known outliers.").)
Examples 2, 5, 6, 7, 8, 12, and the "Summary of the Invention," likewise describe ranges, confidence intervals, and regression equations, established from normative data to compare patient information and to "identify aberrant drug use patterns." (Id. at 3:2028, 45-54; id. at Exs. 2, 5, 6, 7, 8, 12.) These examples provide objective data that the skilled addressee could rely upon to determine the scope of the patented claims. Compare DDR, 773 F.3d at 1259-60 (finding that the term "look and feel" satisfied § 112 because it "had an established, sufficiently objective meaning in the art"), and Augme Techs., Inc. v. Yahoo! Inc., 755 F.3d 1326, 1340 (Fed.Cir. 2014) (finding that the term "receiving, by an ingest server, the unique identifier to the digital content" satisfied § 112 because it was "clear on its face"), with Interval Licensing LLC v. AOL, Inc., 766 F.3d 1364, 1370-71 (Fed.Cir.2014) (finding that the term "unobtrusive manner" was indefinite under § 112 because it was "highly subjective," "provide[d] little guidance to one of skill in the art," and "offer[ed] no objective indication of the manner in which content images are to be displayed to the user").
Moreover, when the skilled addressee views the prosecution history, she would readily appreciate the inventors' explanation that element (f) "allows statistical analysis of the drug metabolite level in the urine to determine if the medication is utilized in a manner consistent with the prescription or that the potential dose may have been." (Mandel Decl., Ex. 24 (dkt. # 129-24) pp. 14-15; id., Ex. 17 (dkt. # 129-17) p. 9.) The use of well-known statistical models in the prosecution history is consistent with the teachings in the specification itself — and, when read together, this would confirm to the skilled addressee with reasonable certainty both how the patented invention works and the
Millennium raises two more arguments that at least deserve mention. First, Millennium emphasizes the term "quantifying the concentration" is not "expressly defined anywhere in the specification or prosecution history of the patents-in-suit." (Def.'s Opening Br. (dkt. # 130) 30.) However, whether the inventors "expressly defined" a claim term is not the test for indefiniteness. See Bancorp Serv., L.L.C. v. Hartford Life Ins. Co., 359 F.3d 1367, 1373 (Fed.Cir.2004) ("The failure to define the term is, of course, not fatal, for if the meaning of the term is fairly inferable from the patent, an express definition is not necessary."). At some level, ambiguity resides in the claims of most (if not all) patented inventions, but as the Supreme Court explained in Nautilus, "[s]ome modicum of uncertainty is the price of ensuring the appropriate incentives for innovation." 134 S.Ct. at 2128-29.
Second, Millennium argues that the claims are indefinite because one of the inventors, Dr. Larson, misunderstood what was meant by the "quantifying" step at his deposition. While Millennium placed heavy emphasis on this point, the Federal Circuit has long recognized that an inventor, represented by counsel during the application process, may not understand the meaning of a precise claim in a patent as issued.
Markman v. Westview Instruments, Inc., 52 F.3d 967, 985-86 (Fed.Cir.1995) (emphasis added); see also Solomon v. Kimberly-Clark Corp., 216 F.3d 1372, 1380 (Fed.Cir.2000); Componex Corp. v. Electronics For Imaging, Inc., 2014 WL 5361946, at *8 (W.D.Wis. Oct. 21, 2014).
In light of the above, both the specification and the prosecution history supply enough notice so that the skilled addressee would understand the scope of the claims with reasonable certainty.
The enablement requirement provides that:
35 U.S.C. § 112(a) (emphasis added).
To be enabling, "the specification of a patent must teach those skilled in the art how to make and use the full scope of the claimed invention without `undue experimentation.'" MagSil Corp. v. Hitachi Global Storage Techs., Inc., 687 F.3d 1377, 1380-81 (Fed.Cir.2012) (citations omitted). "The enablement determination proceeds as of the effective filing date of the patent." Id. (citation omitted). "Enablement serves the dual function in the patent system of ensuring adequate disclosure of the claimed invention and of preventing claims broader than the disclosed invention." Id. (citation omitted, emphasis added). A court may consider the following factors when determining if a disclosure requires undue experimentation: (1) the quantity of experimentation necessary, (2) the amount of direction or guidance presented, (3) the presence or absence of working examples, (4) the nature of the invention, (5) the state of the prior art, (6) the relative skill of those in the art, (7) the predictability or unpredictability of the art, and (8) the breadth of the claims. ALZA Corp. v. Andrx Pharms., LLC, 603 F.3d 935, 940 (Fed.Cir.2010).
Millennium addresses enablement at two levels. On one level, Millennium argues that had the court adopted its proposed construction of element (f), then the claims in both patents are invalid for lack of enablement. Even accepting the court's construction, on another level, Millennium argues that the '895 patent is still invalid due to its failure to teach the claimed methods directed to non-urine biological samples. Since the court did not adopt Millennium's construction, the first argument obviously falls away, but the second of these arguments is persuasive.
As discussed earlier, one skilled in the art would readily appreciate that the claims in the '895 patent are not limited to urine samples, which contrasts starkly with similar claims in the '680 patent. Unlike that patent, the '895 patent claims expressly extend to other biological samples, including "blood, saliva, sweat, and spinal and brain fluids, or a combination thereof." ('895 patent at 4:58-60.) Tellingly, Ameritox neither disputes this contrast, nor explains how the '895 patent teaches the practice of the claimed invention as to any of these non-urine samples except in the broadest possible terms. The court finds this terminal to Ameritox's chances of succeeding with respect to the '895 patent. See, e.g., Liebel-Flarsheim Co. v. Medrad, Inc., 481 F.3d 1371, 1378-79 (Fed.Cir.2007) (holding that the patentee must provide a "reasonable enablement of the scope of the range" of the patented embodiments (emphasis added)); Gen. Elec. Co. v. SonoSite, Inc., 641 F.Supp.2d 793, 817 (W.D.Wis.2009) (explaining that although a patentee need not describe "how to make and use every possible variant of the claimed invention," where claims are "open-ended," the patent would need to be supported by "reasonable enablement of the scope of the range").
In basic patent parlance, the teaching of how to practice the claimed invention supplies the "quid pro quo of the patent bargain." Liebel-Flarsheim, 481 F.3d at 1380; see also Promega Corp. v. Life Technologies Corp., 773 F.3d 1338, 1347 (Fed. Cir.2014) (stating that the "scope of the claims" must be "commensurate" with the specification). In this respect, the '895 patent does not live up to its promise. The only biological sample in the specification is the same urine samples already disclosed and claimed in the '680 patent. Indeed, the bulk of the '895 patent is primarily directed to explaining how creatinine normalization plays a critical role in
Reinforcing the strength of Millennium's argument is the fact that applying creatinine normalization to other biological samples (e.g., blood) makes no sense. As Millennium's unrebutted expert report explained, hydration does not need to be accounted for in non-urine, biological samples, since fluids, like blood, do not reflect variations in hydration like urine. (Wu Invalidity Rept. (dkt. # 115) ¶ 100) (noting that, with respect to non-urine biological samples, "[t]he body already has a defense mechanism in place to prevent wide variation in hydration and dehydration").
While the enablement inquiry also allows assessment of the state of the art and the relative skill of those scientists involved in the industry, the patent fares no better when considering these sources at the time of the '895 patent filing. On the contrary, the lack of teachings in the specification is not saved by what was known outside the specification — i.e. what was common general knowledge or commonplace. When turning to these sources, the skilled addressee would find references such as the George Article that make no reference to how blood applies creatinine normalization to achieve more accurate results. Most likely, this is because, as Dr. Wu opines, it makes no difference since blood has built-in mechanisms to prevent wide variations in hydration. (Id.)
Not only is this not controverted in the parties' summary judgment materials, Ameritox goes so far as to say that the case is not about blood, it's about urine samples. Specifically, Ameritox concludes that because non-urine samples are not relevant to the other issues of this case — in particular, infringement — the court should ignore Millennium's contention that the '895 patent is invalid for lack of enablement. (Pl.'s Opp'n (dkt. # 172) 63-64.) At the same time, Ameritox seems to be conceding that the '895 patent is irrelevant to the current lawsuit, it neither offers to withdraw the patent from these proceedings nor cite law as to how the much broader claims of the '895 patent satisfy an enablement inquiry.
Instead, Ameritox relies principally (really exclusively) on Takeda Pharm. Co. Ltd. v. Zydus Pharm. USA, Inc., 743 F.3d 1359 (Fed.Cir.2014), for the proposition "that the enablement requirement is met if the description enables any mode of making and using the invention." Id. at 1369-70 (internal quotation omitted). More specifically, Ameritox contends that because Millennium does not dispute the "claims are ... enabled and operable with regards to urine ... [, t]hat is enough." (Pl.'s Opp'n (dkt. # 172) 105).
Just as Millennium's application lacked depth with respect to construction, Ameritox suffers from the same vice with respect to enablement on the '895 patent. First, Ameritox makes no effort to square what is said in Takeda — regarding use of the word "mode" — with the well-established rule that the patent must teach how to practice the full scope of an invention. See Wyeth & Cordis Corp. v. Abbott Labs., 720 F.3d 1380, 1384 (Fed.Cir.2013) (citing MagSil Corp., 687 F.3d at 1380-81) ("not enabled when ... one of ordinarily skill in the art could not practice their full scope without undue experimentation"); see also Edwards Lifesciences AG v. CoreValve,
To use the language of Takeda, if the putative mode does not provide means on how to make and use other embodiments of the invention, then it can hardly be considered a mode that allows the skilled addressee to "practice the full scope of the claimed invention." Edwards Lifesciences, 699 F.3d at 1309. This is precisely the case here: there is nothing in the evidence to show how the urine embodiment — Ameritox's putative mode — supplies enough information to the skilled addressee to make and use the invention with respect to samples of blood, saliva, sweat, spinal and brain fluid. Accordingly, the '895 patent is invalid for lack of enablement.
Second, Ameritox's two sentence "analysis" ignores that, as Millennium points out, the Takeda case is factually inapposite to the present. In Takeda, the defendant argued that because the specification only disclosed one method of measuring the drug particles' diameter to determine whether the invention was infringed, the patent did not enable the claims for other methods of measuring drug particles. 743 F.3d at 1369. "[B]ecause the patent identifie[d] laser diffraction as a viable measurement technique, and there [was] no dispute that a skilled artisan would know how to use laser diffraction to measure particle diameter," the Federal Circuit found that the patent "sufficiently enabled the full scope of the claims." Id. (emphasis added). Thus, to satisfy the enablement requirement, the patentee was only required to show that there was at least one mode to determine how differing embodiments (i.e., different sizes of a drug particle) of the invention could infringe.
The present patent claims differ in kind from the patent claims in Takeda in several respects. For instance, while the '895 patent extends to the use of blood samples to quantify drug metabolites, it cannot be said that blood (or any of the other biological samples) are being used as a universal measuring device, as laser diffraction was in the Takeda case. In particular, laser diffraction was a mode for measuring whether an infringing embodiment fell within the full scope of the claims. In contrast, here, each biological source represents an alternative embodiment of how the '895 patent can be implemented. Urine is one embodiment, while blood is another entirely. Because blood is not taught in the specification, blood stretches the scope of the '895 patent beyond its description in the patent. Saliva, sweat, spinal and brain fluids are further embodiments that each expand the scope further. Moreover, each of these biological samples are embodiments of the invention unto themselves, expanding the scope of the '895 patent far beyond what is disclosed in the '680 patent.
In expanding its scope dramatically, Ameritox was required to ensure that the disclosure was "commensurate" with the specification. Its failure to provide the necessary quid pro quo results in the '895 patent being held invalid. See Promega Corp. v. Life Techs. Corp., 773 F.3d 1338, 1347 (Fed.Cir.2014); Nat'l Recovery Techs., Inc. v. Magnetic Separation Sys., Inc., 166 F.3d 1190, 1195-96 (Fed.Cir.1999) ("[T]he public knowledge is enriched by the patent specification to a degree at least commensurate with the scope of the claims... [being] less than or equal to the scope of enablement.").
Similarly, there is nothing in the specification that teaches how creatinine-normalization can be combined with blood (much less other biological samples) to determine
A more apt case than Takeda is Liebel-Flarsheim Co. v. Medrad, Inc., 481 F.3d 1371 (Fed.Cir.2007). On appeal in that case, the patentee unsuccessfully argued as Ameritox does here that the teaching of one embodiment was enough for enablement purposes:
Id. at 1378. In construing the claims, however, the Federal Circuit concluded the claims in Liebel-Flarsheim were "not limited to an injector with a pressure jacket." Id. at 1379. And, therefore, "the full scope of the claimed inventions include[d] injectors with and without a pressure jacket." Id. (emphasis added).
As for the enablement question, and turning to the specification, the Federal Circuit then held that "nowhere does the specification describe an injector with a disposable syringe without a pressure jacket." Id. at 1379. In fact, the Federal Circuit noted, "the specification teaches away from such an invention." Id. When turning to the skilled addressee, the Federal Circuit found that "undue experimentation" would be required "to make and use the injector without a pressure jacket." Id. at 1380. Because the specification did not teach how to make an embodiment of the invention — an injector without a pressure jacket — and because the skilled artesian could not "fill the gaps," the Federal Circuit held the "claims were invalid for lack of enablement." Id.
Strong parallels exist between the present claims in the '895 patent and the claims in the Liebel-Flarsheim patent.
In sum, because of this fairly blatant overreach and because Millennium has demonstrated through clear and convincing evidence that the '895 patent captures far more than what is taught in the specification, the court grants Millennium's motion for invalidity as to the '895 patent pursuant to § 112(a) of the statute. See Edwards Lifesciences AG v. CoreValve, Inc., 699 F.3d 1305, 1309 (Fed.Cir.2012).
Finally, Millennium argues that each of the patents lack utility. Given that the '895 patent does not constitute eligible subject matter and is invalid for lack of enablement, this analysis will be strictly limited to the '680 patent. The threshold of utility "is not high: An invention is `useful' ... if it is capable of providing some identifiable benefit." Juicy Whip, Inc. v. Orange Bang, Inc., 185 F.3d 1364, 1365 (Fed.Cir.1999). To fail the utility requirement, the claims must be totally inoperable. See Brooktree Corp. v. Advanced Micro Devices, Inc., 977 F.2d 1555, 1571 (Fed.Cir.1992) ("To violate § 101 the claimed device must be totally incapable of achieving a useful result."). As previously discussed, Millennium fails to prove this is so here.
Millennium repeats its argument that the asserted claims are not useful because they require definitive dose prediction. Specifically, Millennium asserts that "it is scientifically impossible to predict or determine the dosage of medication taken by a patient from a metabolite/creatinine ratio", the patent lacks utility. (Def.'s Opening Br. (dkt. # 130) 59.) At the outset, Millennium's argument only succeeds if the court adopts its construction of element (f): "quantifying the concentration." That construction, as addressed earlier, was rejected, since it was founded on the flawed premise that the purpose of the patents was to provide a definitive dosage prediction. In order to provide such a result, the invention would have been required to teach the skilled addressee how to correct or adjust for all sources of variability in urine drug concentrations — not just through creatinine normalization.
Nowhere in the '680 patent is this promise made. In fact, the specification expressly acknowledges that the claimed method does not attempt to account for all sources of variability. ('680 patent at 11:11-19.) Because Millennium's utility argument is wedded to the erroneous premise that the invention seeks to predict dosage definitively, when it does not, its argument is rejected.
Contrary to Millennium's understanding of the' 680 patent, the claimed invention is directed to providing a method that allows for improvement in a doctor's ability to determine whether a patient has been taking medication as prescribed. As addressed earlier, and prior to the claimed invention, the only information gained from urine drug testing was the presence or absence of a drug (i.e., the urine samples could only provide for positive or negative testing result). The invention here does more than this; it provides doctors with information that allows assessment of whether a patient "has been using the medication in a manner which is consistent with the prescription." (Id. at 3:1719; see also id. at 4:50-54 (emphasis added).) The
On review of Millennium's briefing, there is nothing by way of evidence that establishes that the invention could not deliver on the new and useful improvements that are stated in the '680 specification. See Juicy Whip, 185 F.3d at 1365. This is Millennium's burden, even more so in the context of summary judgment.
Based on the undisputed positions of the parties on summary judgment and the rulings by the court above, there would appear to be just one arguable issue left for trial as to infringement: whether Millennium's RADAR Report infringes (f) of the '680 patent claims? Even more refined, there would appear to be a single factual dispute: whether the RADAR Report compares "a ratio between the concentration of the test metabolite from the patient to the set of known normative data specific to the reference metabolite concentration."
Even as to this narrow issue, Ameritox and Millennium both maintain that there is no material factual dispute, although they would draw opposite legal conclusions from those facts. Contrary to Millennium's position, however, the undisputed facts would seem to compel the conclusion that it infringes step (f) by use of the RADAR software:
Despite these undisputed facts, Millennium still argues in reply that there are two factual distinctions relieving it of any finding of infringement: (1) the health care provider, not Millennium, makes the comparison; and (2) an individual patient's doctor ultimately decides whether the comparison provided in the RADAR Report has any bearing on assessing a patient's over or under dosing based on a variety of other independent factors. (Def.'s Reply (dkt. # 183) 62-65.)
The first distinction would appear contradicted by the undisputed facts, since Millennium contracts and produces the RADAR Report that provides a comparison
The second distinction morphs with the first and strikes the court as equally meaningless, since the possibility that a doctor may ultimately decide to disregard whether an individual falls inside or outside the 95% confidence range established by the RADAR Report does not mean the report does not infringe, any more than a manufacturer of a thermometer could claim its product does not infringe because a doctor may discount the results of a low or high thermometer reading. Similarly, the fact that the "RADAR Report includes an explicit disclaimer, warning physicians that Millennium makes no interpretations regarding the patient through the RADAR Report" (Def.'s Reply (dkt. # 183) 72), does not mean the Report did not convey the comparison contemplated by (f) of the '680 claims.
Even so, only Millennium actually moved for summary judgment on infringement. Pursuant to Federal Rule of Civil Procedure 56(f), therefore, the court will give Millennium ten days to advise in a supplemental brief why summary judgment should not be entered against it on the question of infringement of the '680 patent. No further briefing or oral argument will be allowed except by express order of the court.
