IN RE SUBPOENA OF QUALCOMM Case No.: 3:25-cv-03197-DMS-VET ORDER DENYING MOTION TO COMPEL THIRD-PARTY INTELLECTUAL VENTURES II LLC, SUBPOENA AND GRANTING Plaintiff, MOTION TO SEAL v. [ECF Nos. 1, 4, 5] TESLA, INC., Defendant. Before the Court is Intellectual Ventures II LLC’s (“IV”) Motion to Compel Rule 30(b)(6) Testimony and Document Production from Third-Party Qualcomm Incorporated. (“Motion to Compel”). ECF No. 4. Therein, IV requests that the Court either transfer the Motion to Compel to the Western District of Texas or, alternatively, compel Qualcomm Incorporated (“Qualcomm”) to designate a witness to testify pursuant to Federal Rule of Civil Procedure 30(b)(6).1 ECF No. 4 at 2–5.2 IV’s related Motion to File Document Under Seal (“Motion to Seal”) is also before the Court. ECF No. 5. 1 Unless otherwise indicated, all references to a “Rule” are to the Federal Rules of Civil Procedure. 2 Page numbers for docketed materials refer to those imprinted by the Court’s electronic For the reasons set forth below, the Court DENIES the Motion to Compel and GRANTS the Motion to Seal. A. Factual Background The Motion to Compel arises from a patent infringement action between IV and Defendant Tesla, Inc. (“Tesla”), pending in the Western District of Texas, Intellectual Ventures II LLC v. Tesla, Inc., Case No. 1:24-cv-00884-ADA (the “Underlying Litigation”). ECF No. 4 at 2–3. IV alleges that Tesla infringes several patents through its use of Qualcomm chips and software enabling connectivity. Id. IV also asserts that Qualcomm has sole possession of certain source code and technical documents required by IV in the Underlying Litigation. Id. According to Qualcomm, Tesla is not its direct customer. ECF No. 8 at 7. Rather, Qualcomm sells chipsets and accompanying software to another company, Quectel Wireless Solutions Co., Ltd. (“Quectel”). Id. Quectel loads Qualcomm’s software onto Qualcomm chips before installing the chips into cellular modules that Quectel then sells to Tesla for use in Tesla vehicles. Id. at 6–8, 13–14. Thus, Qualcomm states, it does not know what version of Qualcomm’s software Quectel loads onto the chips, or, indeed, whether the software is unmodified once installed in Tesla vehicles as a component of Quectel’s cellular modules. Id. B. The Parties’ Discovery Dispute 1. Rule 45 Subpoenas to Qualcomm On May 12, 2025, IV served Qualcomm with a Rule 45 subpoena to produce 17 categories of documents and testify on 18 topics. See ECF No. 4-2 (Ex. 1 at 7, 17–21). IV served Qualcomm with amended Rule 45 subpoenas on May 16, 2025 and November 3, 2025, respectively. ECF Nos. 4-3 (Ex. 2), 4-4 (Ex. 3). The three subpoenas are substantially similar apart from the addition of Topic No. 19 (“authentication and correlation of source code”) to the November 3, 2025 subpoena, and thus IV’s latest subpoena includes a total of 17 requests for documents (“RFP”) and identifies 19 deposition topics (hereinafter the “Subpoena”). ECF No. 4-4 (Ex. 3 at 19–21). In response, Qualcomm timely objected on various grounds to each RFP and Topic Nos. 1 through 18. See ECF No. 8-5 (Ex. B). Qualcomm also notified IV that it was unsure which version of its software Quectel ultimately loaded onto the modules Quectel sold to Tesla, and this information could not be identified without “a valid build ID.” ECF No. 8 at 7. IV subsequently provided information purportedly “relevant to Quectel modules and information related to the IDs” but no actual build IDs. Id. In response, Qualcomm offered IV software build IDs that Qualcomm’s engineering team thought “might have been” used by Quectel.3 Id. Qualcomm also allowed IV to review the relevant software source code for those build IDs at Qualcomm’s secure facility over several dates between July 28, 2025 and October 8, 2025. Id.; ECF No. 4 at 3. 2. Meet and Confer Efforts On October 2, 2026, IV requested to meet and confer regarding scheduling a Rule 30(b)(6) deposition. ECF Nos. 8 at 7; 8-11 (Ex. H). The parties met and conferred telephonically on October 22, 2025. ECF No. 8-3 (Decl. of D. Waslif at ¶ 12). During those discussions, IV clarified that the purpose of the deposition would be to authenticate the source code produced by Qualcomm and correlate it with the Qualcomm chips identified by IV. ECF No. 8 at 8. Qualcomm proposed, rather than arranging a deposition, to provide a correlation chart and for IV and Tesla to stipulate to the authenticity of Qualcomm’s source code as a Qualcomm business record. ECF No. 4 at 3. IV subsequently sought Tesla’s agreement to stipulate to (i) the authenticity of the source code and (ii) “that [the source code] correlates to the chips in Tesla’s vehicles.” ECF No. 8-14 (Ex. K at 2) (IV email to Tesla, dated October 23, 2026). Tesla confirmed that it agreed in principle but

3 Qualcomm notes that this list represented its engineers’ “best educated guess” based on their prior communications with Quectel and a list of Quectel chips IV identified as having been installed in Tesla vehicles. ECF No. 8 at 7 n.3; see also ECF No. 8-1 (Decl. of N. Subramanian at ¶¶ 3–4). Qualcomm cautions, however, that it has no “means to verify whether such software builds were indeed loaded unmodified on to Quectel stated that it first wanted to “review the correlation information” provided by Qualcomm. ECF No. 8-15 (Ex. L at 2) (Tesla email to IV, dated October 27, 2026). Qualcomm provided IV and Tesla with the correlation chart on October 28, 2025. ECF Nos. 4 at 3, 4- 8 (Ex. 7 at 2). On November 4, 2025, Tesla informed IV that it had reviewed the chart, had no objection to stipulating to authenticity, and requested that IV provide a proposed stipulation. ECF No. 8-17 (Ex. N at 2). On November 6, 2025, IV provided a proposed stipulation that, according to IV, had Tesla stipulating “that the code produced is relevant to the Qualcomm chips provided in Tesla vehicles and is utilized in Tesla’s vehicles.” ECF No. 4 at 3–4; see also ECF No. 4- 9 (Ex. 8 at 2) (IV email to Tesla and Qualcomm attaching draft stipulation).4 On November 13, 2025, IV produced a second draft of the proposed stipulation. ECF No. 8 at 8. This draft of the proposed stipulation states, inter alia, that the Qualcomm source code described in the Joint Stipulation is “representative for all Tesla automotive vehicles that include Quectel cellular modules incorporating Qualcomm’s . . . chipsets” and that Qualcomm’s source code for certain chipsets “is used in Tesla vehicles without any modification by Tesla.” Id.; ECF No. 8-19 (Ex. P at 2–5) (draft stipulation). Tesla responded on November 18, 2025 that it did not know to what extent Qualcomm’s source code was representative of the software in Tesla’s vehicles and was not “in a position to stipulate that Qualcomm’s source code is [installed] unmodified” by Quectel. ECF Nos. 8 at 9, 8-20 (Ex. Q at 2). This Motion to Compel followed.5 ECF No. 4. On December 19, 2025, Qualcomm sent IV and Tesla a custodial declaration authenticating as Qualcomm business records (i) the non-source code documents Qualcomm produced to IV; (ii) the hardware source code produced by Qualcomm and
