Opinion

R.N NEHUSHTAN TRUST LTD., Case No. 22-cv-01832-WHO

Plaintiff, ORDER GRANTING MOTION FOR v. LEAVE TO SERVE THIRD AMENDED INFRINGEMENT CONTENTIONS Re: Dkt. Nos. 110, 111, 114, 118 Defendant.

Plaintiff R.N Nehushtan Trust Ltd. (“RNN Trust”) has moved to amend its infringement contentions for the third time, based on information that it represents it gleaned after reviewing defendant Apple Inc. (“Apple”)’s source code, receiving documents that helped it better understand the source code, and conducting technical depositions. Mot. [Dkt. No. 111] 2:3-17. The motion is GRANTED.1 Patent Local Rule 3-6 allows for the amendment of infringement contentions by court order “upon a timely showing of good cause.” “Non-exhaustive examples of circumstances that may, absent undue prejudice to the non-moving party, support a finding of good cause” include “[r]ecent discovery of nonpublic information about the accused instrumentality which was not discovered, despite diligent efforts, before the service of the infringement contentions.” Patent L.R. 3-6. “The good cause inquiry is two-fold: (1) whether the moving party was diligent in amending its contentions; and (2) whether the non-moving party would suffer prejudice if the 1 I granted the parties’ stipulation to an expedited briefing schedule so that this motion could be decided before the September 1, 2023, deadline for expert disclosures. See Dkt. Nos. 95, 113. No motion to amend were granted.” Synchronoss Techs., Inc. v. Dropbox Inc., No. 16-CV-00119- HSG, 2018 WL 5619743, at *3 (N.D. Cal. Oct. 29, 2018) (citation omitted). “Diligence is the critical issue in the good cause determination” and consists of two subparts: “(1) diligence in discovering the basis for amendment; and (2) diligence in seeking amendment once the basis for amendment has been discovered.” Karl Storz Endoscopy-Am., Inc. v. Stryker Corp., No. 14-CV- 00876-RS, 2016 WL 2855260, at *3 (N.D. Cal. May 13, 2016) (citations and quotations omitted). The moving party bears the burden of establishing diligence, but the court has discretion to grant leave to amend “even in the absence of diligence so long as there is no prejudice to the opposing party.” Id. (citations omitted). Prejudice can be shown when there will be disruptions to the case schedule or other court orders, or when a party changes its infringement theories or requires its opposition to prepare additional defenses. See Synchronoss Techs., 2018 WL 5619743, at *5; see also Apple Inc. v. Samsung Elecs. Co., Ltd., No. CV-12-00630-LHK, 2012 WL 5632618, at *3 (N.D. Cal. Nov. 15, 2012). There are two sets of proposed amendments at issue. The first, and easiest to address, are those that Apple does not contest. These amendments largely add support (i.e., citations to deposition transcripts, source code, and technical documents) or further clarify RNN Trust’s existing infringement contentions. See, e.g., Mot., Ex. 19 at 2, 35, 146. The uncontested amendments are highlighted in green in Exhibits 19-24. See Mot. at 10:20-21, Exs. 19-24; see also Oppo. at 6:24-7:24. RNN Trust’s request to make these amendments is GRANTED. What remains are proposed amendments that fall generally into the following categories: (1) those articulating a theory of literal infringement regarding Claim 5 of U.S. Patent No. 9,642,002 (“the ’002 Patent”); and (2) those accusing the devices of infringing by way of: (a) determining how much memory is available on a device for a software update; (b) collecting a certain type of analytics; and (c) automatically updating apps on the device. See, e.g., Mot., Ex. 19 at 2, 35-36, 147, 166; Ex. 22 at 1, 38-39, 155.2 2 The proposed amendments in Exhibit 19 are representative of those in Exhibits 20 and 21. See generally Mot., Exs. 19-21. These amendments relate to claim language in the ’002 Patent and cut RNN Trust contends that it did not discover the need to “further refine its infringement theories” until it received nonpublic information from Apple: the source code, the technical documents, and the technical depositions. Mot. at 2:3-17. At a high level, Apple argues that: (1) RNN Trust was not diligent in discovering the basis for the proposed amendments, nor in seeking them; and (2) the proposed amendments focus on different processes than those underlying RNN Trust’s claims, necessitating the reopening of fact discovery that would prejudice Apple. See Oppo. at 1:10-3:6. RNN Trust was diligent in discovering the basis for its proposed amendments. Although Apple made its source code available to RNN Trust in September 2022, a review of the docket shows that RNN Trust told Apple that it would wait to inspect the source code until after claim construction. See Oppo. at 11:16-19; see also Dkt. No. 61 at 5:9-13. This makes sense given the inherent complexity and sensitivity of source code, the amount of code made available, and the strict parameters for reviewing it. See Dkt. No. 53-1 at 2:9-3:19 (explaining modifications to model protective order to protect the security of the source code at issue). RNN Trust sent its expert to review the source code on May 15, 2023, about six weeks after my claim construction order issued. See Dkt. No. 85; see also Mot. at 5:5-6. RNN Trust continued to act diligently in the weeks and months that followed. Two days after its expert began reviewing the source code, RNN Trust demanded from Apple “technical reference manuals” and other documents “describing the structure, function and operation of the produced source code components.” Mot. at 5:9-14 (citing Ex. 4). Thus began a back-and-forth between the parties over the sought-after documents, which included a meet-and-confer and representations from Apple

relate to the second patent at issue, U.S. Patent No. 9,635,544, and the three types of devices. See generally id., Exs. 22-24.

The parties have filed three motions to redact portions of the briefing and exhibits, and to seal certain exhibits. Dkt. Nos. 110, 114, 118. The motions are GRANTED. The parties’ requests are narrowly tailored, and compelling reasons exist for redacting and sealing these materials, which contain sensitive, confidential technical information about trade secrets. See Wisk Aero LLC v. Archer Aviation Inc., No. 21-CV-02450-WHO, 2022 WL 5007912, at *6 (N.D. Cal. Oct. 4, 2022) (citing In re Midland Nat’l Life Ins. Co. Annuity Sales Pracs. Litig., 686 F.3d 1115, 1119 (9th Cir. that there were no such records. See id. at 5:14-6:8 (citing Exs. 5-9). Although Apple produced three such documents among others on July 7, 2023, RNN Trust did not learn about their significance until the July 18 deposition of Erik Phillips, an Apple software engineer. See id. at 6:9-7:2. Apple’s argument that the basis for at least some of the proposed amendments could have been discovered earlier is unpersuasive. See Oppo. at 11:16-19, 12:17-13:4. Although publicly available sources and certain aspects of the source code may have provided some information at a high level, Apple overlooks details that, as alleged, were provided by RNN Trust’s better understanding of the source code, which did not occur until after the technical documents were provided and the depositions occurred. It also appears that this RNN Trust might have discovered this information sooner had Apple conducted discovery differently. RNN Trust was also diligent in seeking amendment. It filed this motion less than a month after the depositions took place and it realized the significance of the three documents in understanding Apple’s source code. See Dkt. No. 111. A month-long delay does not represent a lack of due diligence, particularly when part of that time was spent seeking additional documents, and meeting and conferring with Apple regarding the proposed amendments. See Mot. at 1:9-11, 8:3-22; see also Wisk, 2022 WL 5007912, at *4 (“The two-month delay between discovering the basis and filing this motion was reasonable, especially in light of Wisk notifying Archer before filing.”). Turning to prejudice, Apple argues that allowing the contested amendments would “necessitate reopening fact discovery”—which closed on August 2, 2023—“to allow Apple to develop defenses to the newly accused processes” by finding and disclosing new witnesses with sufficient knowledge to testify about these processes, producing relevant documents, and supplementing its interrogatory processes. Oppo. at 13:14-15:17; see also Dkt. No. 102. According to Apple, “[t]he delay and expense of reopening discovery is yet another form of prejudice that Apple should not suffer.” Oppo. at 15:15-16. Although prejudice may be shown when there will be disruptions to the case schedule, 1 Synchronoss Techs., 2018 WL 5619743, at *5. Apple would have additional discovery to 2 complete, but so would RNN Trust. If anything, the workload would be less for Apple in that it 3 already has an internal understanding of the processes at issue, which RNN Trust does not. 4 RNN Trust has also plausibly tied its proposed amendments to its existing infringement 5 theories, at least in a manner that suffices at this point. It is not unusual for a patentee to refine its 6 infringement theories after gaining access to nonpublic information such as source code. See 7 Wisk, 2022 WL 5007912, at *3 (“[I]t is unrealistic that a patentee would have a precise sense of its 8 infringement theory at the outset, particularly where the patentee may not have been able to get 9 access to the necessary information because it is hidden from view (for example, source code).”) 10 (citation and quotations omitted). RNN Trust’s proposed amendments seek to refine its 11 infringement theories based on the new information it gleaned about certain processes. Apple may 12 ultimately be able to show that these processes are not related to or otherwise do not infringe upon 13 the patented technology at issue. But that is an evidence-based question that will be answered 14 later. 15 In sum, RNN Trust has shown good cause to amend its infringement contentions. Its 16 motion is GRANTED. A Case Management Conference is scheduled for September 19, 2023, at 3 17 2:00 p.m. to discuss any resulting impacts to the case schedule. A Joint Case Management 18 Statement is due by September 12, 2023. 20 Dated: August 30, 2023 21 . \f 22 . 3 Wilham H. Orrick United States District Judge 24 25 26 27 28
