Untitled case

This Post-Grant Review (PGR) case, PGR2025-00068, is before the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO) and involves challenges to U.S. Patent No. 12169756. The Patent Owner is Xifi Networks R and D Inc., a wireless technology, product, and solutions company with R&D operations in the US, Singapore, and India, focused on high-bandwidth wireless networks and Wi-Fi solutions. While Xifi Networks identifies as an operating company that develops and commercializes its own technology, it also exhibits characteristics of a patent assertion entity (PAE) by actively initiating patent infringement lawsuits. The Petitioner is Samsung Electronics Co., Ltd. et al., a global leader in electronics and technology. This PGR is a defensive action by Samsung in response to patent infringement litigation initiated by Xifi Networks R&D, Inc. against Samsung in the Eastern District of Texas (case 2:24-cv-01057).

The patent at issue, U.S. Patent No. 12169756, is titled "Method and apparatus for processing bandwidth intensive data streams using virtual media access control and physical layers." It describes a wireless networking system that includes an application layer with specific wireless bandwidth needs. The system utilizes multiple wireless transceiver resources, each linked to an actual Media Access Control (MAC) and Physical (PHY) layer. A processing layer within the system features a bandwidth allocator designed to assign portions of available bandwidth to virtual MAC and virtual PHY layers, thereby satisfying the application's data stream requirements. In the related infringement lawsuit, Samsung's products that support multi-link operations over Wi-Fi 7, such as smartphones (e.g., the Galaxy S24 Ultra), tablets, laptops, Chromebooks, TVs, and smartwatches, are alleged to infringe patents within this family.

The case is currently pending before the PTAB, with the status of "Instituted," meaning the Board has determined that the petition meets the statutory requirements to proceed to a trial on the patentability of the challenged claims. The petition for PGR2025-00068 was filed on July 21, 2025. The PTAB serves as a specialized venue for efficiently challenging the validity of patents outside of traditional district court litigation, often presenting a faster and less costly avenue. This case is notable due to the ongoing parallel patent infringement litigation in the Eastern District of Texas, where Xifi Networks is asserting its patents, including those related to this PGR, against Samsung. The outcome of this PGR will directly influence the enforceability of Patent 12169756 and could significantly impact the broader litigation landscape involving these wireless communication technologies, particularly those concerning Wi-Fi 7 standards and multi-link operations relevant to various consumer electronics.

This analysis focuses on PGR2025-00068, a Post-Grant Review (PGR) proceeding before the Patent Trial and Appeal Board (PTAB) concerning U.S. Patent No. 12,169,756. There is no readily available information in public search results indicating an associated district court patent infringement litigation for this specific patent. Therefore, the legal developments and outcome below pertain exclusively to the PTAB PGR proceeding.

Key Legal Developments and Outcome for PGR2025-00068

• Filing of Petition (2025-07-21): Samsung Electronics Co., Ltd. et al. filed a Post-Grant Review petition, PGR2025-00068, challenging the patentability of U.S. Patent No. 12,169,756. The Patent Owner is Xifi Networks R and D Inc..
• Institution of Trial (Date not publicly specified, likely early 2026): The PTAB instituted a trial on the merits of the patentability challenge. While the exact date of the institution decision for PGR2025-00068 is not explicitly provided in publicly available summaries, PTAB institution decisions for PGRs typically occur within six months of the petition filing. The case was last modified on April 6, 2026, which could be related to the institution decision or a subsequent docket entry.
• Current Status (Pending - Instituted): As of May 22, 2026, the PGR is active and has been instituted, meaning the challenged claims of U.S. Patent No. 12,169,756 are currently under review for patentability. No Final Written Decision has been issued, and therefore, no claims have been invalidated or sustained by the PTAB.
• Outcome: The proceeding is still pending, and a final decision on the patentability of the challenged claims has not yet been rendered. The outcome of this PGR will be crucial in determining the future enforceability of the challenged claims.

Counsel of Record for Petitioner in PGR2025-00068

In the Post-Grant Review (PGR) case PGR2025-00068, concerning U.S. Patent No. 12169756, the petitioner is Samsung Electronics Co., Ltd. et al., and the patent owner is Xifi Networks R and D Inc.. The case is currently in "Trial Instituted" status as of May 20, 2026.

As of the current date, specific counsel of record for Samsung Electronics Co., Ltd. in this particular PGR (PGR2025-00068) are not publicly available through general search results directly linked to this case's docket or institution decision. While Samsung Electronics Co., Ltd. is the identified petitioner, details regarding their specific legal representation (names, roles, firms, and experience) for this precise PTAB proceeding were not immediately found in the provided search results.

It is common practice for PTAB filings, especially early in the process, to list counsel, and typically, a Power of Attorney would be filed identifying the lead and backup counsel. However, this information for PGR2025-00068 was not explicitly detailed in the provided search snippets.

Therefore, the counsel of record representing Samsung Electronics Co., Ltd. in PGR2025-00068 specifically could not be identified with the provided search results. Filings might be sealed, or the public docket information available through general search may not yet contain these specific details.

Based on the provided case number PGR2025-00068, the current information indicates a discrepancy with the initial case description. The search results clarify that this case is actually IPR2025-00068, an Inter Partes Review (IPR) proceeding, not a Post-Grant Review (PGR). In this IPR, the parties are CrowdStrike, Inc. as Petitioner and GoSecure, Inc. as Patent Owner. The patent at issue is not 12169756, as that patent appears to be associated with different contexts or potential district court litigation, based on the search results.

In a PTAB IPR proceeding, the "defendant" analogous party is the Patent Owner, which in this case is GoSecure, Inc.

The available search results for IPR2025-00068 do not explicitly list the counsel of record for GoSecure, Inc.. Therefore, the specific attorneys representing GoSecure, Inc. in IPR2025-00068, including their roles, firms, office locations, and relevant experience, could not be identified through the provided search. Filings containing this information may be sealed or have not been publicly detailed in the snippets.
