Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE EASTERN DISTRICT OF TEXAS MARSHALL DIVISION W&WSENS DEVICES INC., § § Plaintiff, § § v. § CASE NO. 2:24-CV-00854-JRG § SAMSUNG ELECTRONICS CO., LTD. § and SAMSUNG ELECTRONICS § AMERICA, INC., § § Defendants. § MEMORANDUM OPINION AND ORDER Before the Court is the Renewed Motion to Transfer (the “Motion”) filed by Defendants Samsung Electronics Co., Ltd. (“SEC”) and Samsung Electronics America, Inc. (“SEA”) (together, “Samsung”). (Dkt. No. 58). In the Motion, Samsung moves to transfer this case to the United States District Court for the Northern District of California (“NDCA”). (Id. at 1). Having considered the Motion and its related briefing, and for the reasons set forth herein, the Court finds that the Motion should be DENIED. I. BACKGROUND On the April 16, 2025, Plaintiff W&Wsens Devices Inc. (“Plaintiff”) filed the Second Amended Complaint for Patent Infringement (the “SAC”). (Dkt. No. 52). In the SAC, Plaintiff accuses Samsung of infringing six (6) patents: U.S. Patent No. 12,243,948; U.S. Patent No. 12,087,871; U.S. Patent No. 11,621,360; U.S. Patent No. 10,468,543; U.S. Patent No. 10,446,700; and U.S. Patent No. 9,525,084 (collectively, the “Asserted Patents”). (Dkt. No. 52 ¶¶ 25–32). Generally, each of the Asserted Patents relates to Complimentary Metal-Oxide Semiconductor (“CMOS”) image sensors which “capture light and convert it into an electrical signal and are used in almost every smartphone and digital camera today.” (Id. ¶¶ 15, 33.) The SAC provides that Samsung of makes, uses, sells, and offers for sale within the United States, and imports into the United States, several infringing products. (Id. ¶ 44). Those products include Samsung’s CMOS image sensors and time-of-flight sensors (the “Accused Sensors”).

(Id.). Those products also include Samsung’s products which include the CMOS image sensors, such as Samsung’s Galaxy product line (the “Accused Smartphones”) (together with the Accused Sensors, the “Accused Products”). (Id.). II. LEGAL STANDARD “For the convenience of parties and witnesses, in the interest of justice, a district court may transfer any civil action to any other district or division where it may have been brought.” 28 U.S.C. § 1404(a). The question of whether a suit “might have been brought” in the transferee forum encompasses subject matter jurisdiction, personal jurisdiction, and propriety of venue. Viking Techs., LLC v. Assurant, Inc., 2021 WL 3520756, at *1 (E.D. Tex. June 21, 2021) (quoting

Hoffman v. Blaski, 363 U.S. 335, 343–44 (1960)). If this threshold burden is satisfied, the party seeking transfer must then establish that transfer is warranted in the interest of convenience. In evaluating a motion to transfer pursuant to § 1404(a), the Court considers the Fifth Circuit’s non-exhaustive list of private and public interest factors. In re Volkswagen AG, 371 F.3d 201, 203 (5th Cir. 2004) (“Volkswagen I”). The private interest factors include: (1) “the relative ease of access to sources of proof,” (2) “the availability of compulsory process to secure the attendance of witnesses,” (3) “the cost of attendance for willing witnesses,” and (4) “all other practical problems that make trial of a case easy, expeditious and inexpensive.” (Id.). The public interest factors include: (1) “the administrative difficulties flowing from court congestion,” (2) “the local interest in having localized interests decided at home,” (3) “the familiarity of the forum with the law that will govern the case,” and (4) “the avoidance of unnecessary problems of conflict of laws or the application of foreign law.” (Id.). While a plaintiff’s choice of venue is not an express factor in this analysis, the appropriate deference afforded to the plaintiff’s choice is reflected in a defendant’s elevated burden of proof.

In re Volkswagen of Am., Inc., 545 F.3d 304, 315 (5th Cir. 2008) (“Volkswagen II”). To support its claim for a transfer under § 1404(a), the defendant must demonstrate that the transferee venue is “clearly more convenient” than the venue chosen by the plaintiff. (Id.). Absent such a showing, however, the plaintiff’s choice is to be respected. (Id.). “When deciding a motion to transfer under § 1404(a), the Court may consider undisputed facts outside of the pleadings, such as affidavits or declarations, but must draw all reasonable inferences and resolve factual conflicts in favor of the non-moving party.” Hammers v. Mayea-Chang, 2019 WL 6728446, at *4 (E.D. Tex. Dec. 11, 2019) (collecting cases). III. ANALYSIS

(a) Whether this case could have been brought in the NDCA? The threshold inquiry is “whether the judicial district to which transfer is sought would have been a district in which the claim could have been filed.” Volkswagen I, 371 F.3d at 203. Plaintiff does not dispute that it could have brought this case in the NDCA as SEC is a foreign corporation and SEA has an office in Mountain View, CA. (Dkt. No. 58 at 5; see also Dkt. No. 62). Accordingly, the Court finds that Plaintiff could have brought this case in the NDCA. (b) Private interest factors The parties dispute whether the private interest factors weigh in favor of transfer. The Court addresses each of these factors in turn. (1) The relative ease of access to sources of proof First, Samsung argues that the relative ease of access to sources of proof favors transfer.

(Dkt. No. 58 at 5). As support, Samsung points to three (3) categories of sources of proof. (Id. at 6–10). The Court addresses each category below. (A) Samsung’s sources of proof In the Motion, Samsung argues that its own sources of proof are more easily accessed in the NDCA than the Eastern District of Texas (“this District”). (Dkt. No. 58 at 6–7). Samsung maintains that, while the “vast majority, if not all, of” SEC’s document custodians, technical documents, and physical evidence is in the Republic of Korea (“South Korea”), South Korea is closer to the NDCA than this District. (Id.). Samsung also asserts that third-party Samsung Semiconductor, Inc. (“SSI”) has technical documents relating to the function and operation of the

Accused Sensors in the NDCA. (Id. at 7 (citing Dkt. No. 58-2 ¶¶ 10–15)). According to Samsung, these technical documents are more relevant than those held by SEA in this District. (Id.; see also Dkt. No. 67 at 2). Plaintiff argues in response that Samsung’s sources of proof are centered in this District, not the NDCA. (Dkt. No. 62 at 4). Plaintiff asserts that SEA generates testing documents for the Accused Smartphones and financial records for its sales thereof in Plano, Texas. (Id. at 4–5). Additionally, Plaintiff argues that SEC’s sources of proof are equally accessible in both this District and the NDCA because those sources of proof are in South Korea. (Id. at 5, 7 (citation omitted)). The Court disagrees with Samsung. The Court notes that Samsung weighs SSI’s source of proof twice, once as a part of Samsung’s sources of proof and once as a third-party source of proof. (See Dkt. No. 58 at 7 (citing Dkt. No. 58-2 ¶¶ 10–15); Id. at 8). The Court declines to consider SSI’s sources here as doing so would allow “a single source of proof [to] . . . unduly influence the analysis.” AGIS Software Dev. LLC v. Huawei Device USA Inc., No. 2:17-cv-00513-JRG, 2018

WL 2329752 at *3 (E.D. Tex. May 23, 2018) (citation omitted). Additionally, SEC’s sources of proof do not weigh in favor of transfer. SEC’s sources are, by Samsung’s own admission, almost entirely in South Korea. (Dkt. No. 58 at 6–7).
