LEONARD P. STARK, District Judge.
Pending before the Court is Defendant Blackberry Corporation's ("Defendant" or "Blackberry") Motion for Judgment on the Pleadings filed pursuant to Federal Rule of Civil Procedure 12(c). (D.I. 75) ("Motion") Blackberry contends that claims 31-38 of U.S. Patent No. 6,185,681 ("'681 patent")
MAZ Encryption Technologies LLC ("Plaintiff' or "MAZ") sued Blackberry on February 22, 2013, alleging infringement of the '681 patent. (D.I. 1) The '681 patent is entitled "Method of Transparent Encryption and Decryption for an Electronic Document Management System" and relates to transparently integrating encryption and decryption functionality into an electronic document management system ("EDMS"). ('681 patent at Abstract) The PTO conducted an ex parte reexamination of the patent, which resulted in cancellation of original claims 1-30 and addition of claims 31-38. (D.I. 1-1 Ex. A, Ex Parte Reexamination Certificate ("Reexamination Certificate"))
The parties completed briefing on Defendant's Motion on May 27, 2015. (D.I. 76, 83, 87) The Court issued a Memorandum Opinion on claim construction on June 30, 2015. (D.I. 93)
The parties filed Daubert and summary judgment motions on April 22, 2016. (D.I. 155, 157, 159, 161, 164) Prior to a hearing on the parties' Daubert and summary judgment motions, the Court ordered the parties to submit supplemental briefing on Defendant's§ 101 Motion in light ofrecent decisions by the Court of Appeals for the Federal Circuit addressing§ 101. (D.I. 208) The parties completed supplemental briefing on Defendant's Motion on July 22, 2016. (D.I. 209, 210, 211, 212, 213, 214) The Court heard oral argument on the parties' Daubert and summary judgment motions and on the recent§ 101 cases on August 17, 2016. (D.I. 219 ("2016 Tr."))
Pursuant to Federal Rule of Civil Procedure 12(c), a party may move for judgment on the pleadings "[a]fter pleadings are closed — but early enough not to delay trial." When evaluating a motion for judgment on the pleadings, the Court must accept all factual allegations in a complaint as true and view them in the light most favorable to the non-moving party. See Rosenau v. Unifund Corp., 539 F.3d 218, 221 (3d Cir. 2008); see also Maio v. Aetna, Inc., 221 F.3d 472, 482 (3d Cir. 2000). This is the same standard that applies to a Rule 12(b)(6) motion to dismiss. See Turbe v. Gov't of Virgin Islands, 938 F.2d 427, 428 (3d Cir. 1991).
A Rule 12(c) motion will not be granted "unless the movant clearly establishes that no material issue of fact remains to be resolved and that he is entitled to judgment as a matter of law." Rosenau, 539 F.3d at 221. "The purpose of judgment on the pleadings is to dispose of claims where the material facts are undisputed and judgment can be entered on the competing pleadings and exhibits thereto, and documents incorporated by reference." Venetec Int'l, Inc. v. Nexus Med., LLC, 541 F.Supp.2d 612, 617 (D. Del. 2008); see also In re Burlington Coat Factory Sec. Litig., 114 F.3d 1410, 1426 (3d Cir. 1997) (explaining that any documents integral to pleadings may be considered in connection with Rule 12(c) motion). "The issue is not whether a plaintiff will ultimately prevail but whether the claimant is entitled to offer evidence to support the claims." Burlington Coat Factory, 114 F.3d at 1420. Thus, a court may grant a motion for judgment on the pleadings (like a motion to dismiss) only if, after "accepting all well-pleaded allegations in the complaint as true, and viewing them in the light most favorable to plaintiff, plaintiff is not entitled to relief." Maio, 221 F.3d at 482 (3d Cir. 2000).
The Court may consider matters of public record as well as authentic documents upon which the complaint is based if attached to the complaint or as an exhibit to the motion. See Oshiver v. Levin, Fishbein, Sedran & Berman, 38 F.3d 1380, 1384 n.2 (3d Cir. 1994). The Court may also take judicial notice of the factual record of a prior proceeding. See Oneida Motor Freight, Inc. v. United Jersey Bank, 848 F.2d 414, 416 n.3 (3d Cir. 1988). Ultimately, a motion for judgment on the pleadings can be granted "only if no relief could be afforded under any set of facts that could be proved." Turbe, 938 F.2d at 428.
Under 35 U.S.C. § 101, "[w]hoever 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." There are three exceptions to § 101's broad patent-eligibility principles: "laws of nature, physical phenomena, and abstract ideas." Diamond v. Chakrabarty, 447 U.S. 303, 309 (1980). Pertinent here is the third category, "abstract ideas," which "embodies the longstanding rule that an idea of itself is not patentable." Alice Corp. Pty. Ltd. v. CLS Bank Int'l, 134 S.Ct. 2347, 2355 (2014) (internal quotation marks omitted). "As early as Le Roy v. Tatham, 55 U.S. 156, 175 (1852), the Supreme Court explained that `[a] principle, in the abstract, is a fundamental truth; an original cause; a motive; these cannot be patented, as no one can claim in either of them an exclusive right.' Since then, the unpatentable nature of abstract ideas has repeatedly been confirmed." In re Comiskey, 554 F.3d 967, 977-78 (Fed. Cir. 2009).
In Mayo Collaborative Servs. v. Prometheus Labs., Inc., 132 S.Ct. 1289 (2012), the Supreme Court set out a two-step "framework for distinguishing patents that claim laws of nature, natural phenomena, and abstract ideas from those that claim patent-eligible applications of those concepts." Alice, 134 S. Ct. at 2355. First, courts must determine if the claims at issue are directed to a patent-ineligible concept — in this case, an abstract idea ("step 1"). See id. If so, the next step is to look for an "`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' ("step 2"). Id. The two steps are "plainly related" and "involve overlapping scrutiny of the content of the claims." Elec. Power Grp., LLC v. Alstom S.A., 2016 WL 4073318, at *3 (Fed. Cir. Aug. 1, 2016).
At step 1, "the claims are considered in their entirety to ascertain whether their character as a whole is directed to excluded subject matter." Internet Patents Corp. v. Active Network, Inc., 790 F.3d 1343, 1346 (Fed. Cir. 2015) (emphasis added); see also Affinity Labs of Texas, LLC v. DIRECTV, LLC, 2016 WL 5335501, at *3 (Fed. Cir. Sept. 23, 2016) ("The `abstract idea' step of the inquiry calls upon us to look at the `focus of the claimed advance over the prior art' to determine ifthe claim's `character as a whole' is directed to excluded subject matter."). Claims implemented purely in software are not necessarily directed to patent-ineligible abstract ideas under step 1. See Enfish, LLC v. Microsoft Corp., 822 F.3d 1327, 1335 (Fed. Cir. 2016) ("Software can make non-abstract improvements to computer technology just as hardware improvements can...."); id. ("We thus see no reason to conclude that all claims directed to improvements in computer-related technology, including those directed to software, are abstract and necessarily analyzed at the second step of Alice, nor do we believe that Alice so directs."); see also id. at 1338 ("[W]e are not persuaded that the invention's ability to run on a general-purpose computer dooms the claims."); id. at 1339 ("Much of the advancement made in computer technology consists of improvements to software that, by their very nature, may not be defined by particular physical features but rather by logical structures and processes.") (emphasis added).
At step 1, the Federal Circuit has distinguished claims that are "directed to
Courts should not "oversimplifiy]" key inventive concepts or "downplay" an invention's benefits in conducting a step-1 analysis. See id. at 1337; see also McRO, Inc. v. Bandai Namco Games Am. Inc., 2016 WL 4896481, at *7 (Fed. Cir. Sept. 13, 2016) ("[C]ourts `must be careful to avoid oversimplifying the claims' by looking at them generally and failing to account for the specific requirements of the claims.") (quoting In re TLI Commc'ns LLC Patent Litig., 823 F.3d 607, 611 (Fed. Cir. 2016)). "Whether at step one or step two of the Alice test, in determining the patentability of a method, a court must look to the claims as an ordered combination, without ignoring the requirements of the individual steps." McRO, 2016 WL 4896481, at *7.
At step 2, the Federal Circuit has instructed courts to "look to both the claim as a whole and the individual claim elements to determine whether the claims contain 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." McRO, 2016 WL 4896481, at *7 (internal brackets and quotation marks omitted). The "standard" step-2 inquiry includes consideration of whether claim elements "simply recite `well-understood, routine, conventional activit[ies].'" Bascom Glob. Internet Servs., Inc. v. AT&T Mobility LLC, 827 F.3d 1341, 1350 (Fed. Cir. 2016) (quoting Alice, 134 S. Ct. at 2359). "Simply appending conventional steps, specified at a high level of generality, [is] not
However, "[t]he inventive concept inquiry requires more than recognizing that each claim element, by itself, was known in the art." Bascom, 827 F.3d at 1350. In Bascom, the Federal Circuit held that "the limitations of the claims, taken individually, recite generic computer, network and Internet components, none of which is inventive by itself," but nonetheless determined that an
The "mere recitation of a generic computer cannot transform a patent-ineligible abstract idea into a patent-eligible invention" under step 2. Alice, 134 S. Ct. at 2358. "Given the ubiquity of computers, wholly generic computer implementation is not generally the sort of additional feature that provides any practical assurance that the process is more than a drafting effort designed to monopolize the abstract idea itself." Id.
The Supreme Court has instructed that, "in applying the§ 101 exception, [courts] must distinguish between patents that claim the building blocks of human ingenuity and those that integrate the building blocks into something more, thereby transforming them into a patent-eligible invention." Alice, 134 S. Ct. at 2354 (internal citation and quotation marks omitted). The "concern that drives the exclusionary principle [i]s one of pre-emption." Id. That is, where a patent would preempt use of "basic tools of scientific and technological work," i. e., "[l]aws of nature, natural phenomena, and abstract ideas," the patent would "impede innovation more than it would tend to promote it, thereby thwarting the primary object of the patent laws." Id. (internal quotation marks omitted).
The Federal Circuit has considered the issue of preemption at both steps 1 and 2. For example, in McRO, 2016 WL 4896481, at *9, in support of its conclusion that a claim was patent-eligible under step 1, the Federal Circuit held that limitations of a claim "prevent[ed] preemption of all processes for achieving automated lip-synchronization of 3-D characters." In Bascom, 2016 WL 3514158, at *7, in support of the Court's conclusion that claims reciting "a specific, discrete implementation of the abstract idea of filtering content" were patent-eligible under step 2, the Federal Circuit explained that the claims did not preempt "all ways of filtering content on the Internet."
The parties dispute which burden of proof applies in deciding questions of patent eligibility under § 101. Plaintiff cites a vacated Federal Circuit opinion in support of its position that a clear and convincing standard should apply. (D.I. 83 at 8) (citing Ultramercial, Inc. v. Hulu, LLC, 722 F.3d 1335, 1342 (Fed. Cir. 2013), cert. granted, judgment vacated sub nom. WildTangent, Inc. v. Ultramercial, LLC, 134 S.Ct. 2870 (2014) ("[A]ny attack on an issued patent based on a challenge to the eligibility of the subject matter must be proven by clear and convincing evidence.")) Defendant argues that the clear and convincing standard should not apply, because patent eligibility is a question of law, "subject to a lesser evidentiary burden." (D.I. 87 at 1) (citing In re Bilski, 545 F.3d 943, 951 (Fed. Cir. 2008))
Patent eligibility is a question of law. See Rapid Litig. Mgmt. Ltd. v. CellzDirect, Inc., 827 F.3d 1042, 1047 (Fed. Cir. 2016). Whatever evidentiary standard should be applied would only apply to subsidiary "questions of fact and not to questions of law." Microsoft Corp. v. i4i Ltd. P'ship, 564 U.S. 91, 114 (2011) (Breyer, J., concurring).
Here the parties agree that there are no disputed questions of fact relevant to Defendant's Motion. (2015 Tr. 3, 36) Thus, the Court's decision is made purely as a matter of law and does not turn on questions of fact, obviating the need for the Court to choose a particular standard of proof. See Rosenau, 539 F.3d at 221.
The parties agree that claim 31 is representative of all claims of the '681 patent for purposes of the Court's§ 101 analysis. (2015 Tr. 10, 36) Claim 31 recites:
(Reexamination Certificate at 1:21-58)
Step 1 requires the Court to consider whether the claims are directed to a patent-ineligible abstract idea. Viewed as a whole, claim 31 describes a process that enables frictionless, "behind-the-scenes" encryption — when a user closes or saves a file, the invention automatically obtains an appropriate encryption key, encrypts the file, and saves the encrypted file in an EDMS. According to the specification of the '681 patent, the claimed invention is a
Defendant argues that claim 31 is directed to conventional elements that are "combined in the same manner as in the prior art." (See, e.g., D.I. 211 at 3) This argument raises a fundamental problem with Defendant's choice to bring its § 101 challenge under Rule 12(c). As noted above, the parties agree that there are no disputed issues of fact relevant to Defendant's Motion and, therefore, have not "presented" evidence "outside the pleadings" that might trigger Rule 12(d)'s requirement that the Court treat Defendant's Motion as a motion for summary judgment under Rule 56. Fed. R. Civ. P. 12(d). Defendant could have filed a motion for summary judgment instead of a motion under Rule 12,
Viewed in light of the patent's specification, and the current record before the Court, claim 31 is
The patent's specification describes problems associated with "typical" prior art encryption systems, such as incompatibility with EDMS systems and general difficulty of use. (See '681 patent at 3:54-4:9) The '681 patent purports to solve these problems using a method that the PTO determined was non-obvious over references considered during the ex parte reexamination of the patent. (See D.I. 77 Ex. 5 at 13-14) For example, claim 31 recites use of two tables, one for pairing documents with key names and one for pairing key names with key values. Separation of the two pairings has functional significance, as explained in the specification. The specification further explains that a "smart card 265 preferably is used to keep the encryption and decryption keys
Defendant proposes at least five different articulations of the abstract idea to which, in Defendant's view, claim 31 is directed: (1) "storing and accessing keys used to encrypt/decrypt documents," (2) "organizing and storing information safely," (3) "us[ing] computer technology to ... stor[e] and access[] keys," (4) "data manipulation," and (5) "storing and accessing data (filenames and encryption keys) in a logical tabular format." (D.I. 76 at 5, 16-17) Plaintiff argues that "Defendant's inability to identify a single abstract idea to which the '681 Patent is directed demonstrates the impropriety of its allegations." (D.I. 83 at 10) In response, Defendant argues that it was merely describing the same abstract idea in several different ways. (D.I. 87 at 6-7) ("The supposed `five abstract ideas' ... are simply five different ways of expressing the same abstract idea of `organizing and storing information safely.'")
Regardless of whether Defendant's five articulations are viewed as different or the same, they each run afoul of the Federal Circuit's guidance in Enfish that courts should not "oversimplif[y]" key inventive concepts or "downplay" an invention's benefits in conducting a step-1 analysis. 822 F.3d at 1337; see also McRO, 2016 WL 4896481, at *7. "Whether at step one or step two of the Alice test, in determining the patentability of a method, a court must look to the claims as an ordered combination,
Significant "individual steps" in claim 31 were added during reexamination, including the above-described use of tabular association of documents with "key names" and "key names" with "key values." (See D.I. 77 at 13-14) (summarizing exchange between applicant and examiner regarding "key name <—> document association" limitation added to overcome obviousness rejection) These limitations were added to distinguish the claimed invention from the "key-directory association" found in the prior art and are evidence that claim 31 is "directed to a specific improvement to the way computers operate" rather than an abstract idea. Enfish, 822 F.3d at 1336. Defendant's broad articulations of abstract ideas do not capture what claim 31 is "directed to" because they do not take into account the two separate tables used to distinguish claim 31 over the prior art. Although not every difference between a purported invention and the prior art is necessarily relevant under a § 101 analysis, here it is plain from the reexamination prosecution history (with support in the specification) that the two-table limitations added during reexamination are sufficiently important that they must be included in any accurate description of the nature of claim 31 as a whole. See Affinity Labs, 2016 WL 5335501, at *3 ("The `abstract idea' steps of the inquiry calls upon us to look at the `focus of the claimed advance over the prior art' to determine if the claim's `character as a whole' is directed to excluded subject matter.").
Defendant tacitly acknowledges the significance of the two-table limitations in arguing that, "[w]hen stripped away of all the concepts that previously existed in the prior art, the only novel concepts identified by the patentee are (1) key name — file association in the first table and (2) key name — key value association in the second table." (D .I. 76 at 15) Defendant states that "[t]hese are quintessentially abstract concepts." (Id.) Defendant's approach of "stripping away" concepts alleged to be in the prior art to expose only the "novel concepts," completely shorn of their surrounding context, was expressly rejected in McRO. "[A] court must look to the claims as an ordered combination, without ignoring the requirements of the individual steps." McRO, 2016 WL 4896481, at *7. Viewed as an ordered combination, claim 31 recites a specific implementation of transparent encryption, not a computer implementation of an abstract idea.
Defendant argues that the claimed invention is patent ineligible because "each step in the asserted claims could be analogously performed by a human, rather than a computer." (D.I. 76 at 15) Defendant postulates that "the storage and utilization of filenames, key names, and key values recited in the patent claims is no different substantively than how an old hotel would store and keep track of the keys to its patrons' rooms." (D.I. 76 at 15) Defendant continues:
Moreover, encryption is a relatively sophisticated, computer-implemented method of protecting data, unlike the simple, human-executable method described in Defendant's analogy. As described in the '681 patent's specification, "Encryption is a process of scrambling data utilizing a mathematical function called an encryption algorithm, and a key that affects the results of this mathematical function. . . . With most encryption algorithms, it is nearly impossible to convert cipher text back to clear text without knowledge of the encryption key used." ('681 patent at 3:17-24)
In addition, the entire exercise of comparing the invention in claim 31 to a human-executable series of steps is relatively unhelpful in this particular case, because the specification of the '681 patent so clearly identifies the claimed invention as "improv[ing] an existing
Finally, Defendant argues that the method in claim 31 is "merely a form of data manipulation" like others that have been found to be patent-ineligible. (D.I. 76 at 16) (citing Digitech Image Techs., LLC v. Elecs.for Imaging, Inc., 758 F.3d 1344, 1350 (Fed. Cir. 2014); Content Extraction & Transmission LLC v. Wells Fargo Bank, Nat. Ass'n, 776 F.3d 1343, 1351 (Fed. Cir. 2014)) The Digitech and Content Extraction cases are distinguishable. ill Digitech, the Federal Circuit held that a claimed method was "`so abstract and sweeping' as to cover any and all uses" of a particular concept. 758 F.3d at 1351 (quoting Gottschalk v. Benson, 409 U.S. 63, 68 (1972)). There is no evidence here that claim 31 is similarly "abstract and sweeping." Instead, the specific tabular limitations narrow the claim to a particular implementation of transparent data encryption. Claim 31 does not
The claims at issue in Content Extraction "merely recite[d) the use of ... existing scanning and processing technology to recognize and store data from specific data fields such as amounts, addresses, and dates." 776 F.3d at 1348. The Content Extraction Court held that "[t]he concept of data collection, recognition, and storage is undisputedly well-known. Indeed, humans have always performed these functions." Id. at 1347. As already discussed above, claim 31 is not analogous to a human-executable process, unlike the claims in Content Extraction. Moreover, claim 31 is directed to more than pure data manipulation. It is directed to a
For the foregoing reasons, the Court concludes that representative claim 31, and therefore all asserted claims 31-38, are not directed to an abstract idea.
As indicated inMcRO, 2016 WL 4896481, at *9, the preemption-focused question of whether a claim disproportionately ties up use of underlying ideas covered by the claim may be considered in connection with an analysis at step 1. The specific implementation in claim 31 raises fewer preemption concerns than the broader, original claims of the '681 patent which were rejected during reexamination. Defendant has not produced any evidence to support any preemption concerns. Consequently, the preemption consideration confirms the Court's conclusion at step 1 that claim 31 is not directed to an abstract idea. See id. ("There has been no showing that any rules-based lip-synchronization process must use rules with the specifically claimed characteristics.").
Plaintiff proffers expert testimony in support of its position that claim 31 is patent-eligible. (D.I. 84 Ex. 2 (Expert Declaration of Dr. Craig Wills)) Because Defendant's Motion must be evaluated under Rule 12, the Court does not weigh Plaintiffs expert testimony in its ultimate decision. Nevertheless, the Court notes that (1) Plaintiffs expert opines that "many other unclaimed system architectures and methods are available to address the purpose of the claimed invention [in claim 31]" (D.I. 84 Ex. 2 ¶ 13) and (2) Defendant offers no expert testimony to rebut Dr. Wills's opinions in this regard. Hence, if the Court were to factor in the extrinsic evidence, this would only further support the Court's conclusion that the claims are patent eligible.
Because the Court resolves the § 101 challenge at step 1, the Court does not need to consider whether the claims also involve an inventive concept. However, the Court notes that it opined during the 2016 hearing that "[i]t does appear that [Defendant's] obviousness defense is quite strong." (2016 Tr. at 133) This assessment of Defendant's obviousness case is relevant under step 2 because "[c]ourts have found guidance in deciding whether the allegedly abstract idea (or other excluded category) is indeed known, conventional, and routine, or contains an inventive concept,
The Court ultimately denied Defendant's motion for summary judgment on obviousness, holding that a reasonable jury could find that a person of ordinary skill in the art would not reasonably expect success in combining Defendant's asserted prior art references. (2016 Tr. at 132-33) In Bascom, 827 F.3d at 1350, the Federal Circuit cited a lack of any "reason to combine the limitations as claimed" as a basis for rejecting the district court's analysis related to obviousness, which was undertaken to support the district court's § 101 conclusion (by showing that claim limitations were found in the prior art). The Federal Circuit instructed that "[t]he inventive concept inquiry requires more than recognizing that each claim element, by itself, was known in the art." Id.
Thus, while the Court continues to view Defendant's obviousness arguments as relatively strong, Defendant's identification of each limitation in the prior art, by itself, would be insufficient under Bascom to render Plaintiff's claims patent-ineligible, even had the Court not already determined that the claims are not directed to an abstract idea.
For the reasons stated above, on the record before the Court in connection with Defendant's Motion, claims 31-38
