Case Overview and Background: Wilus Institute of Standards and Technology Inc. v. Samsung Electronics Co., LTD., et al.

This patent infringement litigation, Case No. 2:25-cv-00070, was filed in the U.S. District Court for the Eastern District of Texas on January 23, 2025. The plaintiff is Wilus Institute of Standards and Technology Inc., identified as a Patent Assertion Entity (NPE). The defendants are Samsung Electronics Co., LTD. and Samsung Electronics America, Inc. This case has been consolidated with a related action against HP Inc. (Case No. 2:25-cv-00069) into a lead case, 2:25-cv-00069-JRG-RSP.

While the prompt initially identified U.S. Patent 12004262 as at issue, court documents and related proceedings consistently point to U.S. Patent No. 11,664,926 (the "'926 Patent"), along with related patents such as U.S. Patent 10,820,233 and U.S. Patent 10,931,396, as being asserted by Wilus against the defendants. The '926 Patent generally relates to wireless communication methods and devices, specifically involving techniques for efficient data transmission in wireless communication systems. The accused products, services, or technology are Wi-Fi 6 (802.11ax) enabled devices, such as routers and other consumer electronics manufactured by Samsung and HP Inc.

The case is currently before District Judge Rodney Gilstrap and Magistrate Judge Roy S. Payne in the Eastern District of Texas, Marshall Division. This venue is notable for patent litigation due to its historical reputation as a "rocket docket" with an accelerated trial schedule and a perceived plaintiff-friendly environment. Judge Gilstrap, in particular, has a significant number of patent cases on his docket and is often referred to as the country's "busiest patent judge." A trial date for the consolidated litigation is set for August 17, 2026, with claim construction briefing scheduled for January 2026 and a claim construction hearing for February 26, 2026. The case is also notable for its linkage to multiple Inter Partes Review (IPR) proceedings at the Patent Trial and Appeal Board (PTAB), where defendants are challenging the validity of the asserted patents, including the '926 patent, related to Wi-Fi 6 technology. This highlights the common strategy of major technology companies to challenge patent validity at the USPTO concurrently with district court litigation.

Key Legal Developments and Outcome for Wilus Institute of Standards & Technology, Inc. v. Samsung Electronics Co., LTD., et al.

This patent infringement litigation, Case No. 2:25-cv-00070, was filed in the Eastern District of Texas by Wilus Institute of Standards & Technology, Inc. (WILUS) against Samsung Electronics Co., LTD., and Samsung Electronics America, Inc. (collectively, "Samsung"). The case is currently active and proceeding towards a scheduled trial.

Chronological Legal Developments:

2025-01-23: Case Filing & Initial Pleadings
Wilus Institute of Standards & Technology, Inc. filed a complaint for patent infringement against Samsung Electronics Co., LTD. and Samsung Electronics America, Inc. in the U.S. District Court for the Eastern District of Texas, Marshall Division (Case No. 2:25-cv-00070). The complaint alleges infringement related to Wi-Fi 6 technology.

2025-03-25: Case Consolidation
Case 2:25-cv-00070 was consolidated for all pretrial issues with a related case, Wilus Institute of Standards and Technology Inc. v. HP Inc. (Case No. 2:25-cv-00069), before Chief Judge Rodney Gilstrap. Case 2:25-cv-00069 serves as the lead case for pretrial matters. Other cases filed by Wilus against ASUSTek were also consolidated before Judge Gilstrap.

Post-Filing: Answer and Counterclaims
Samsung filed an answer to the complaint, which included counterclaims addressing the obligations of both WILUS and Sisvel International S.A. to license the patents-in-suit on fair, reasonable, and non-discriminatory (FRAND) terms. This is part of a broader set of pre-trial proceedings aimed at narrowing the issues to be decided at trial.

2025-06-13: Docket Control Order & Trial Scheduling
A First Amended Docket Control Order was issued in the consolidated lead case (2:25-cv-00069-JRG), setting a jury selection date for August 17, 2026, in Marshall, Texas. This trial date is considered a firm deadline, "a deadline that cannot be changed without an acceptable showing of good cause." The order also set deadlines for disclosing final invalidity theories, prior art references, and equitable defenses by the defendant (7 days before jury selection), and plaintiff's final election of asserted claims (10 days before jury selection).

2026-03-06: Pre-trial Motions of Substance (Motion for Partial Summary Judgment on FRAND)
Wilus brought a motion for partial summary judgment arguing that the defendants' (Samsung and Askey) alleged bad-faith negotiations justify suspending Wilus's RAND obligations. Samsung is opposing this motion, contending that FRAND obligations remain binding regardless of negotiation conduct. Askey is challenging the motion on procedural grounds, arguing that bad faith and FRAND suspension were not properly pleaded or relevant at this stage, and that the request is premature for summary judgment. The outcome of this motion could significantly impact the remedies available at trial, potentially exposing implementers to higher, uncapped patent damages if Wilus's position is accepted.

Claim Construction (Markman):
As of the current available information, there is no specific Markman hearing outcome detailed for the patent(s) asserted in this particular case (2:25-cv-00070) or its consolidated lead case (2:25-cv-00069). However, Markman hearings for other patents in related litigation before Judge Gilstrap have been mentioned, such as for U.S. Patent 9,171,268 in case 2:25-cv-00782-JRG.

Discovery Milestones:
Specific detailed discovery milestones with strategic significance beyond the general schedule outlined in the Docket Control Order are not publicly available in detail from the search results. However, the Docket Control Order itself provides key dates for the exchange of contentions. Plaintiff served infringement contentions on May 14, 2025, and Petitioner (Samsung) served invalidity contentions on July 9, 2025.

Parallel PTAB IPR/PGR Proceedings:

Several Inter Partes Review (IPR) proceedings have been initiated by Samsung against patents asserted by Wilus, including:

• IPR2025-01165 was filed by Samsung Electronics Co., Ltd. on June 24, 2025, against U.S. Patent No. 11,664,926, which is asserted in the consolidated district court litigation (2:25-cv-00069 and 2:25-cv-00070). Wilus, as the patent owner, filed a request for discretionary denial of institution, arguing that the district court trial is set for August 17, 2026, which is nearly five months before the anticipated Final Written Decision (FWD) date of January 12, 2027, for the IPR. This argument suggests a stay of the district court litigation pending IPR outcome is unlikely given Judge Gilstrap's precedent in similar situations.
• IPR2025-00934 was filed by Samsung Electronics Co., Ltd. against claims 1-9 of U.S. Patent No. 11,159,210 B2, with an institution decision issued on November 3, 2025. This patent is also related to Wilus's litigation.

The prompt mentions US Patent 12004262 as being at issue. While the search results extensively cover the Wilus v. Samsung and Wilus v. HP consolidated cases (2:25-cv-00070 and 2:25-cv-00069) and their associated IPRs, the specific patent 12004262 has not been explicitly identified as being asserted in these particular consolidated cases from the provided search snippets. The IPRs and litigation details predominantly mention patents 11,664,926 and 11,159,210 in the context of Wilus's Wi-Fi 6 related assertions. Therefore, without further information, it cannot be confirmed that US Patent 12004262 is at issue in case 2:25-cv-00070.

Outcome:
The litigation is ongoing, with a jury trial currently scheduled for August 17, 2026. The outcomes of the various pending motions, including Wilus's motion for partial summary judgment regarding RAND obligations, will shape the course of the trial. The parallel IPR proceedings, particularly the request for discretionary denial, highlight a key strategic aspect where the timing of the PTAB's final decisions relative to the district court trial date is a significant factor. The final disposition (settlement, dismissal, judgment, or appeal) is yet to be determined.
