NITA L. STORMES, Magistrate Judge.
Plaintiff Ameranth, Inc. and defendants OpenTable, Inc., Wanderspot, LLC and Best Western International, Inc.
After the original case was filed in August 2011, and before it was consolidated for pretrial purposes with over 30 other cases, Ameranth served amended preliminary infringement contentions (PICs) on the original defendants on June 18, 2012.
On October 4, 2012, 30 cases were consolidated with the original case, 11cv1810. This court held an initial Case Management Conference (CMC) for all consolidated cases on November 14, 2012, and a second CMC on February 20, 2013. Following the second CMC, the court issued an order setting forth a schedule for Ameranth to serve infringement contentions and accompanying documents on a staggered schedule on the various defendant groups. Dkt. No. 345, p.3. According to the PLR, a party claiming patent infringement must serve separately on all opposing parties a "Disclosure of Asserted Claims and Infringement Contentions." PLR 3.1. The ICs served in the consolidated action on defendants OpenTable, Wanderspot and Best Western are the subject of this dispute.
In the ICs, Ameranth asserts direct infringement claims against Defendants based on their make and use of online and mobile reservations systems. Alternatively, if the court determines that the direct infringers are actually the consumers who book reservations or the restaurants that accept such reservations on the systems, then Ameranth asserts that Defendants are indirect infringers because they provide and operate the system components described in the ICs to other persons and promote their use in a manner designed to infringe the patents.
The issues in this discovery dispute concern the extent of specificity required by this district's PLR to adequately assert infringement contentions. While this court is aware that some judges here have addressed this issue either directly (see, e.g., Case No. 10cv2618-H (KSC), Dkt. No. 175, Order Denying Defendants' Request to Strike Plaintiff's Preliminary Infringement Contentions), or peripherally (see, e.g., Case No. 12cv739-JLS (NLS), Dkt. No. 57, Order Denying Motion for Partial Summary Judgment), it is not aware of any Southern District case that evaluates the persuasive authority of the case law from the Northern District of California concerning the required specificity for ICs.
The purpose of local patent rules is to streamline discovery and "provide structure to discovery and enable the parties to move efficiently toward claim construction and the eventual resolution of their dispute." Am. Video Graphics, L.P. v. Elec. Arts, Inc., 359 F.Supp.2d 558, 560 (E.D. Tex. 2005) (citing Network Caching Tech. v. Novell, Inc., 2002 U.S. Dist. LEXIS 26098, *12, 2002 WL 32126128, *5 (N.D. Cal. Aug. 13, 2002)). Such rules streamline discovery by "replac[ing] the series of interrogatories that accused infringers would likely have propounded in [their] absence." Solannex, Inc. v. MiaSolé, Inc., 2013 U.S. Dist. LEXIS 56672, *5-*6, 2013 WL 1701062, *2 (N.D. Cal. April 18, 2013). Patent local rules are "designed specifically to require parties to crystallize their theories of the case early in the litigation so as to prevent the shifting sands approach to claim construction." O2 Micro Int'l, Ltd. v. Monolithic Power Sys., 467 F.3d 1355, 1364 (Fed. Cir. 2006) (internal quotations and citation omitted).
Infringement contentions have a specifically defined purpose:
Apple Inc. v. Samsung Elecs. Co., 2013 U.S. Dist. LEXIS 91450, *35-*36, 2013 WL 3246094, *3 (N.D. Cal. June 26, 2013).
Ameranth argues that the court should deny Defendants' arguments for these reasons: (1) other Defendants already challenged the sufficiency of the ICs in the partial summary judgment motions and lost; (2) OpenTable's challenge is late because Ameranth served amended ICs on OpenTable on June 18, 2012 and OpenTable never challenged them; (3) the ICs are sufficiently detailed and comply with PLR 3.1; (4) Defendants cannot simultaneously fail to produce discovery relevant to the issues in the ICs and complain about the sufficiency of the ICs; and (5) its ICs meet the requirements of PLR 3.1.
Ameranth argues that Defendants attempt to circumvent the district judge's denial of two partial motions for summary judgment concerning Ameranth's PICs as to the `325 and `850 patents. Defendants argue that the summary judgment rulings do not render this issue moot. They point out that Ameranth relied not only on its PICs but also an expert declaration and other citations to documents and source code. Ameranth counters that the court did not factor in the expert declaration or extrinsic evidence in ruling on the sufficiency of the PICs.
Second, Defendants argue that those summary judgment motions concerned only the `325 and `850 patents. Ameranth responds that the same level of detail already determined to be sufficient is used in ICs for the `077 claims.
Finally, Defendants argue that the additional disclosure obligations in this motion, including disclosures related to the doctrine of equivalents, the different versions of the accused systems, and alleged indirect infringement, do not render the issues in this motion moot. Particularly, disclosures regarding indirect infringement were added to the PLR on December 4, 2012, over two months after briefing for the summary judgment motions was complete.
In the orders, Judge Sammartino found that Ameranth's PICs were sufficient and that Defendants should not further challenge them until after claim construction. See, e.g., Case No. 12cv729, Dkt. No. 55, p.12. But she framed the issue as being one of claim construction rather than sufficiency of the of the PICs:
Case No. 12cv739, Dkt. No. 57, p.10; see Case No. 12cv729, Dkt. No. 55, p.12. Further, Judge Sammartino relied on expert evidence to make her decision:
Case No. 729, Dkt. No. 55, p.12.
Given the additional grounds raised in this motion, and Judge Sammartino's framing of her ruling as an issue for claim construction rather than sufficiency of ICs as well as her reliance on expert evidence, this court does not believe those orders dispose of all the issues presented in this motion.
Ameranth originally served ICs on OpenTable in 2012 in the non-consolidated action. It argues that OpenTable's current objections in the consolidated action should be deemed untimely because it did not object to those original 2012 ICs. The court finds that OpenTable's current challenge to the 2013 ICs is timely. These newly-served ICs include a new patent and disclosures related to direct infringement, which were not required until six months after the 2012 ICs were served. Also, Ameranth agreed to extend the deadline for OpenTable to file this motion.
Ameranth argues it complies with the plain language of PLR 3.1e and properly asserts the doctrine of equivalents. The rule requires that each IC contain this information:
PLR 3.1e.
Ethicon Endo-Surgery v. U.S. Surgical Corp., 149 F.3d 1309, 1315 (Fed. Cir. 1998) (internal quotations and citation omitted).
For each claim element, Ameranth included this blanket statement: "If this element is not found to be literally present, it is present under the doctrine of equivalents." See, e.g., ICs to OpenTable, Ex. 1, p.19. Ameranth takes the position that PLR 3.1e simply requires a patentee to identify without further elaboration those claim elements it contends are present under the doctrine of equivalents. Whether it can actually proceed on that theory as to any claim element, according to Ameranth, is a question to be resolved in the future. This court disagrees.
In this court's view the questions of whether, how and when Ameranth should assert doctrine of equivalents theories in its contentions are questions to be answered now, and not in the future. At least one court in the Northern District of California has rejected a patentee's request to reserve the right to assert an infringement theory based on the doctrine of equivalents until after claim construction, stating that "under no reading of the Patent Local Rules do they provide for a place holder to assert future claims of infringement." Fr. Telecom, S.A. v. Marvell Semiconductor, Inc., 2013 U.S. Dist. LEXIS 63823, *17, 2013 WL 1878912, *6 (N.D. Cal. May 3, 2013).
As noted by the court in Apple, the purpose of infringement contentions is to alert the alleged infringer which theories the patentee believes its pre-filing investigation supports. Therefore, a patentee should provide its doctrine of equivalents theories at the beginning of the case if it has a good faith basis to assert them. Apple, 2013 U.S. Dist. LEXIS at *37; 2013 WL 3246094 at *4 (footnote omitted). The Apple court noted:
Id. at *36; *3. The Apple court further cautioned that "absent a change in circumstances (and the diligence of the party who needs to amend), a change in theory after the case has progressed is unjustified." Id.
As to the specificity required for asserting an infringement theory under the doctrine of equivalents, there used to be some uncertainty in the law. Practically all the case law in this circuit comes from the Northern District of California and analyzes a patent local rule almost identical to the PLR 3.1e at issue here.
Several other Northern District cases expressly require a limitation-by-limitation analysis. Nazomi Communs., Inc. v. Nokia Corp., 2013 U.S. Dist. LEXIS 85618, *19, 2013 WL 3146796, *5 (N.D. Cal. June 18, 2013) (simply stating that to the extent an element is not literally infringed the accused product "embodies the claim element or limitation under the doctrine of equivalents" is insufficient to comply with the PLR); Rambus Inc. v. Hynix Semiconductor Inc., 2008 U.S. Dist. LEXIS 123187, *41-*42 (N.D. Cal. Dec. 29, 2008) (finding grounds to grant summary judgment of non-infringement under the doctrine of equivalents because plaintiff did not comply with PLR and only provided a boilerplate reservation as opposed to a limitation-by-limitation analysis); GN Resound A/S v. Callpod, Inc., 2013 U.S. Dist. LEXIS 40402, *17-*18, 2013 WL 1190651, *6 (N.D. Cal. March 21, 2013) (requiring an element-by-element analysis) accord CSR Tech., Inc. v. Freescale Semiconductor, 2013 U.S. Dist. LEXIS 17502, *25-*26, 2013 WL 503077, *8-*9 (N.D. Cal. Feb. 8, 2013).
This court is not aware of any case in the Southern District that addresses this issue of whether blanket assertions of the doctrine of equivalents satisfies the PLR or whether a limitation-by-limitation specificity is required. However, ample and recent case law from the Northern District squarely answers this question. Based on the similarity to the Northern District's rule, the number of recent and persuasive cases coming from that district, and the policy behind patent local rules to "crystallize . . . theories of the case early in the litigation," O2 Micro Int'l, 467 F.3d at 1364, this court finds good cause to follow the decisions coming out of the Northern District regarding assertion of the doctrine of equivalents. See NessCap Co. v. Maxwell Techs., Inc., 2008 U.S. Dist. LEXIS 3357, *4, 2008 WL 152147, *1 (S.D. Cal. Dec. 5, 2007) (Major, J.) (relying on published and unpublished cases interpreting the patent local rules from the Northern District of California and Northern District of Georgia as persuasive authority).
Defendants argue that Ameranth failed to identify or describe any acts by the alleged indirect infringers that contribute to direct infringement. To describe indirect infringement, Ameranth must comply with this rule:
PLR 3.1d (emphasis added).
Ameranth's contributory infringement allegations largely mimic the statutory elements of contributory infringement:
See, e.g., ICs to OpenTable, Ex. 1, pp.12-13. In comparison, the statutory elements of contributory infringement read:
35 U.S.C. § 271(c).
Boilerplate language that simply tracks the elements required to show contributory infringement and that does not specify how the selling contributes to infringement of the asserted claims "does not suffice." Creagri, Inc. v. Pinnaclife Inc., LLC, 2012 U.S. Dist. LEXIS 158540, *16, 2012 WL 5389775, *3 (N.D. Cal. Nov. 2, 2012) (Grewal, J.). But Ameranth argues it also includes descriptions of specific acts. For example, as to OpenTable, it states: "intentionally encouraging direct infringement," "provides instruction and direction regarding the use of the Accused System," "widely advertises and promotes use of the OpenTable Reservation System by consumers in the media and on OpenTable's website(s)." Jt. Mtn., p.3. As to Wanderspot, Ameranth describes its indirect acts as "intentionally encouraging indirect infringement," and "provides instruction and direction regarding the use of the Urbanspoon Reservation and Table Management System." Jt. Mtn., p.4.
While an accusing party must "crystallize" its theory and "identify how . . . products infringe with as much specificity as possible with the information currently available to it," the party need not provide concrete evidence along with the ICs or "point[] to the specific structures within the accused product that embodies the claim limitations." Solannex, U.S. Dist. LEXIS 56672 at *12-*13, 2013 WL 1701062 at *4 (Grewal, J.). Even if some of the ICs closely mirror the claim language, those ICs are adequate if the cited factual support is specific and sufficient to put the accused party on notice. Id.
Here, Ameranth includes some basic descriptions of acts of indirect infringement. See, e.g., Ex. 1, p.12. But they are not sufficient and do not explain the facts relied upon. For example, Ameranth refers to Exhibit 100 but does not provide the court with a copy of that exhibit or explain what facts in that exhibit support a theory of contributory infringement. Ameranth must amend its allegations of contributory infringement to properly disclose the facts it has that support that theory.
Ameranth asserts that it identified all accused versions of Defendants' systems to the extent reasonably possible with systems that are comprised of multiple aspects and components, and do not have overall "version numbers" or "version names" or other simple identifiers. Ameranth argues that differences between "versions" of the accused products are minimal "bug fixes" that do not alter the infringing nature of the accused product. It asserts that it identified the accused versions temporally, by their functional aspects, and in some cases, by their components' version names or numbers.
Defendants argue that Ameranth includes a single claim chart for the most current version of each of the asserted claims, yet tries to accuse all previous versions of Defendants' systems without specifically identifying them. Defendants ask that Ameranth be compelled to provide a separate chart or otherwise show that the accused previous versions are the same as or reasonably similar to the charted version.
To comply with the requirements of PLR 3.1 and promote the purpose of forcing an accusing party to "crystallize" its infringement theories, an opposing party should not be "forced to guess which versions of its products infringes the patent." Bender v. Freescale Semiconductor, Inc., 2010 U.S. Dist. LEXIS 91281, *5-*6, 2010 WL 1689465, *3 (N.D. Cal. Apr. 26, 2010) (quotations and citations omitted). Further, the purpose of PLR 3.1 is to be "nit picky." InterTrust Techs. Corp. v. Microsoft Corp., 2003 U.S. Dist. LEXIS 22736, *8, 2003 WL 23120174, *4 (N.D. Cal. 2003)).
While Ameranth says it identified the accused versions temporally, by their functional aspects or by their version names or numbers, it must at least state how the accused previous versions are the same or reasonably similar to the charted version, or else provide a separate chart for each version. In other words, it must amend its ICs and explain how each mode allegedly infringes.
Ameranth says that using the latest versions of the mobile applications, it provided charts alleging that the accused systems meet each of the asserted claim limitations. It cited to public and non-public documents (where available) and stated, to the best of its ability, where each element of the asserted claim is found within the accused system. Defendants argue that Ameranth's ICs are not particular because they do not identify where and how many claim limitations are allegedly found with the accused systems.
The rule requires that for each opposing party, the IC include:
PLR 3.1c.
Defendants ask the court to follow the Northern District's interpretation of the analogous PLR in that district and require Ameranth to describe how the accused systems practice the asserted claims. In opposition, Ameranth asserts that the "how" is a topic to be addressed by experts following claim construction. It argues that PLR 3.1c does not require it to describe with any degree of specificity how the accused system practices the claimed elements.
Infringement contentions that mostly copy the language of the patent claim are insufficiently vague. Network Caching Tech., LLC v. Novell, Inc., 2002 U.S. Dist. LEXIS 26098, *16-*18 (N.D. Cal. Aug. 13, 2002). An accusing party must link any cited evidence regarding the accused system to the IC. Id. at *18 (noting reliance on defendant's marketing literature was insufficient because it was not specifically linked to the IC); see Tessenderlo Kerley, Inc. v. Or-Cal, Inc., 2012 U.S. Dist. LEXIS 52486, *7, 2012 WL 1253178, *2 (N.D. Cal. Apr. 13, 2012) ("Broad inferences cannot stand in place of factual information"). Specifically regarding claim charts, an accusing party must provide the level of detail required to meet the "reverse engineering or its equivalent" standard. InterTrust, 2003 U.S. Dist. LEXIS 22736, *8, 2003 WL 23120174, *2-3. To comply with this standard, the asserting party must explain its theory of how the product infringes the claim element. GN Resound A/S v. Callpod, Inc., 2013 U.S. Dist. LEXIS 40402, *11, 2013 WL 1190651, *4 (N.D. Cal. Mar. 21, 2013). It must "articulate the precise way in which it believes the products to be infringing." Tessenderlo, 2012 U.S. Dist. LEXIS, *11, 2012 WL 1253178, *4.
Next to each identified claim, Ameranth attempts to identify the location of elements of the claim within the accused instrumentality, and cites to third party news articles, commentaries, online blogs and marketing materials. Jt. Mtn., p.18; See, e.g., ICs to OpenTable, Ex. 1, p.13. It does not cite to any source code. Defendants argue that citing to portions of the code would allow Ameranth to identify, with reasonable particularity:
Jt. Mtn., pp.18-19. In the case of OpenTable, Ameranth had access to their source code for several months before serving amended ICs, so this information should be readily available.
Ameranth admittedly does not explain "how" the accused systems practice the claimed elements. Jt. Mtn., p.9. The court finds that PLR 3.1c requires more. Ameranth must amend its ICs to link the cited evidence to its claims, and provide the level of detail required to meet the "reverse engineering or its equivalent" standard. See InterTrust, 2003 U.S. Dist. LEXIS 22736, *8, 2003 WL 23120174, *2-3. What this means is that Ameranth must identify with specificity where in the accused system the alleged infringement occurs and how the claim elements are met.
For good cause shown, the court follows the persuasive authority of the Northern District in interpreting analogous patent local rules and
