Unified Patents PTAB Data v. Xifi Networks R and D Inc.

This inter partes review (IPR) proceeding, IPR2025-01206, involves Unified Patents PTAB Data as the Petitioner challenging US Patent 11950105, owned by Xifi Networks R and D Inc. Unified Patents is a membership organization that seeks to deter Non-Practicing Entities (NPEs) by proactively filing IPRs against patents they consider "bad," often those asserted in district court litigation. Xifi Networks R and D Inc. is a wireless technology, product, and solutions company focused on WiFi broadband internet access, which develops and patents technology aimed at enhancing wireless performance. However, Xifi Networks R and D Inc. is also actively asserting a portfolio of wireless networking patents, including US 11950105, against major operating companies like Samsung in district court, indicating a patent assertion entity (PAE) strategy in this context.

The patent at issue, US Patent 11950105, is titled "Systems and methods for multi-link operations in a wireless local area network." It generally relates to foundational wireless communication technologies, specifically for multi-link WiFi operations. This patent is one of eleven asserted by Xifi Networks R and D Inc. in a patent infringement lawsuit filed against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the Eastern District of Texas (Case 2:24-cv-01057). The accused products in that parallel litigation include Samsung's electronic devices—such as smartphones, TVs, laptops, tablets, and wearable devices—that implement multi-link WiFi operations functionality, particularly referencing Wi-Fi 7 standards.

The IPR is currently "Pending - Instituted" at the Patent Trial and Appeal Board (PTAB), meaning the Board has determined there is a reasonable likelihood that at least one challenged claim of US Patent 11950105 is unpatentable, and a trial has commenced. The PTAB provides a specialized, administrative forum for challenging patent validity based on prior art, often serving as a faster and more cost-effective alternative to district court litigation. The institution of this IPR is notable because it directly targets a patent actively asserted in significant district court litigation against a major electronics manufacturer, underscoring Unified Patents' strategy to use IPRs to challenge patents asserted by entities perceived as NPEs. A successful IPR could result in the cancellation of claims, significantly impacting Xifi's ability to enforce the patent in the ongoing infringement case. The panel of Administrative Patent Judges assigned to this IPR includes Scott A. Daniels, Jameson Lee, and Stacey G. White.

Key Legal Developments and Outcome for IPR2025-01206

This Inter Partes Review (IPR) proceeding, IPR2025-01206, involves U.S. Patent 11,950,105. According to the case metadata, Unified Patents PTAB Data is the petitioner, and Xifi Networks R and D Inc. is the patent owner. However, public records indicate that Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. are the petitioners in this IPR, challenging Xifi Networks R&D, Inc. as the patent owner. Consistent with operating rules, this summary will refer to Unified Patents PTAB Data as the petitioner, while acknowledging the conflicting public record.

Filing & Initial Pleadings:

• Petition Filing: On July 3, 2025, a petition for inter partes review was filed challenging claims 1-30 of U.S. Patent 11,950,105. The grounds for the challenge were based on obviousness under 35 U.S.C. § 103, citing prior art references Chincholi, Riggert, and Clegg.
• Patent Owner Preliminary Response and Discretionary Denial Request: On July 21, 2025, Xifi Networks R&D, Inc. (the Patent Owner) filed a request for discretionary denial of institution. This request argued that institution would be inefficient given parallel district court litigation and that the petition relied extensively on questionable expert testimony.

Parallel District Court Litigation:

• Complaint Filing: A parallel patent infringement lawsuit, XiFi Networks R&D, Inc. v. Samsung Electronics Co., Ltd. et al, Case No. 2:24-cv-01057-JRG, was filed by Xifi Networks R&D, Inc. against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the U.S. District Court for the Eastern District of Texas on December 17, 2024. U.S. Patent 11,950,105 is among the patents asserted in this litigation.
• Discovery and Trial Schedule: The district court established a case schedule, setting a trial date for October 19, 2026. The parties were actively engaged in discovery as of July 2025.
• Claim Construction: An amended joint claim construction statement was filed on February 27, 2026, in preparation for a claim construction (Markman) hearing scheduled for April 29, 2026, in the district court case.

Pre-trial Motions of Substance (PTAB):

• Institution Decision: Despite the Patent Owner's request for discretionary denial, the IPR was instituted. The exact date of the institution decision is not explicitly detailed in the provided search snippets, but the status given in the prompt indicates that institution occurred. The filing of the petition on July 3, 2025, and the Patent Owner's arguments against institution in July 2025, suggest the institution decision would have been issued around early 2026, typically within six months of the preliminary response.

Outcome / Present Posture:

• Current Status: The IPR, IPR2025-01206, is currently listed as "Pending - Instituted." This means the PTAB has determined that the petitioner, Unified Patents PTAB Data (or, as per public records, Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc.), has shown a reasonable likelihood that at least one challenged claim is unpatentable, and the trial phase of the IPR is underway. No final written decision or termination due to settlement has been found in the available search results as of the current date. The district court litigation remains active with a claim construction hearing held in April 2026 and a trial scheduled for October 2026.

It appears there is a discrepancy in the provided case metadata regarding the plaintiff for IPR2025-01206. According to the institution decision for IPR2025-01206, the petitioners are Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc., while Xifi Networks R&D, Inc. is the Patent Owner. The case metadata states "Unified Patents PTAB Data" as the plaintiff. Given the direct information from the institution decision, Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. are the petitioners in this IPR.

Therefore, the counsel for the plaintiff(s) (Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc.) would be associated with those entities, not Unified Patents PTAB Data, based on the provided search results. Without a direct docket sheet or specific appearance information for this particular IPR from a reliable source, the exact counsel of record for Samsung in IPR2025-01206 cannot be definitively identified from the current search results. General searches for "Unified Patents PTAB Data IPR counsel" indicate that Unified Patents often uses outside counsel from firms like Erise IP and Haynes and Boone, LLP, in addition to their in-house counsel such as David Seastrunk and Roshan Mansinghani for various IPR proceedings. However, these examples are for other IPRs filed by Unified Patents, not for IPR2025-01206.

Therefore, specific counsel for the plaintiff(s) in IPR2025-01206 cannot be identified from the current information due to the conflicting plaintiff information and lack of specific attorney appearances for Samsung in this particular IPR.

(the Patent Owner in this inter partes review), is provided by Robins Kaplan LLP. This information is drawn from a closely related IPR, IPR2025-01204, which also lists Xifi Networks R&D, Inc. as the Patent Owner.
