IPR2026-00079, an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB), addresses the validity of U.S. Patent No. 12,112,357B2. The patent owner is Weple IP Holdings LLC, identified as a Non-Practicing Entity (NPE) and an entity of MAF Holdings LLC. While the specific petitioner for IPR2026-00079 is not definitively identified in public search results, Meta Platforms, Inc. has been a petitioner challenging Weple IP Holdings LLC in other recent IPRs concerning related patents, suggesting a potential adversarial context for this proceeding as well. The patent, titled "Mobile device streaming media application," broadly covers a system and process for coordinating streaming content or messages, specifically detailing servers that receive and store media messages with expiration information, generate distinct feeds, and provide these to a mobile application with sharing functionalities. Given this is an IPR, the focus is on the patent's validity, not an "accused product" in the traditional sense of an infringement case.

The case's procedural posture is significant because the IPR was "Not Instituted - Procedural" by the PTAB. This outcome reflects recent, substantial shifts in PTAB practice under the leadership of Director John A. Squires, who has centralized institution authority since late 2025. This has led to an increase in discretionary denials, where the PTAB may decline to institute an IPR on procedural grounds, even if a petitioner meets the statutory likelihood of prevailing on the merits. Factors considered in such discretionary denials include the "settled expectations" of the patent owner, the existence of parallel district court litigation, whether the petitioner has filed multiple "copycat" petitions, and, more recently, considerations related to U.S. manufacturing activities. The precise procedural reason for the non-institution of IPR2026-00079 is not publicly detailed, but it falls within this broader trend of the Director exercising increased discretion.

IPR2026-00079 is notable primarily due to its "Not Instituted - Procedural" status amid the PTAB's recent policy changes that have made obtaining IPR institution more challenging for petitioners. The patent owner being an NPE like Weple IP Holdings LLC underscores the continuing landscape of patent assertion and the defensive strategies employed by operating companies, which are now facing a more patent-owner-friendly environment at the PTAB. This shift impacts the strategic calculus for both patent challengers and owners, influencing how intellectual property disputes, particularly those involving economically significant mobile streaming media technology, are navigated.

This summary addresses the Inter Partes Review (IPR) case IPR2026-00079 concerning US Patent 12112357B2. It's important to note that the provided case number is for a PTAB IPR, not a district court patent infringement litigation. Searches for a specific district court patent infringement litigation involving US Patent 12112357B2 did not yield publicly available details. Therefore, the traditional milestones of patent infringement litigation (such as filing, answers, counterclaims, Markman hearings, discovery, trial, verdict, or post-trial motions) cannot be provided for a specific district court case.

However, the IPR itself represents a key legal development related to the patent's validity.

Parallel PTAB IPR Proceedings and Outcome:

• IPR Filing: On October 31, 2025, Petitioner Meta Platforms Inc. filed IPR2026-00079, challenging US Patent 12112357B2, owned by Weple IP Holdings LLC. The technology involved is classified under "High-Tech."
• Outcome - Not Instituted - Procedural: The Patent Trial and Appeal Board (PTAB) ultimately decided not to institute the Inter Partes Review, with the status recorded as "Not Instituted - Procedural." This means the PTAB did not proceed to a full review of the patent's validity on the merits. While the specific procedural reason for the non-institution of IPR2026-00079 is not explicitly detailed in publicly available search results, such procedural denials can occur for various reasons. Common grounds for procedural non-institution include issues with identifying all real parties in interest, the petition being time-barred, or discretionary denial under factors outlined in decisions like Fintiv, which consider the stage of any parallel district court litigation and other efficiency and fairness considerations. The Director of the USPTO also has discretion in instituting IPRs, with policy changes impacting institution rates and considerations.
• Effect on Litigation: Since the IPR was not instituted on procedural grounds, it did not result in a final written decision regarding the patentability of the claims of US Patent 12112357B2. Without a confirmed parallel district court patent infringement litigation for this specific patent, the direct effect of this IPR's non-institution on such a litigation cannot be detailed. If a district court case exists, the non-institution of the IPR means that the patent's validity was not challenged at the PTAB, leaving any validity arguments to be litigated in the district court.

The provided case, IPR2026-00079, is an Inter Partes Review (IPR) proceeding at the Patent Trial and Appeal Board (PTAB), not a patent infringement case in a district court. In an IPR, the party challenging the patent is referred to as the "Petitioner," and the party defending the patent is the "Patent Owner." The case status is "Not Instituted - Procedural," which means the PTAB did not proceed with a full review of the patent's validity.

As of May 29, 2026, a direct search for IPR2026-00079 on publicly available PTAB databases and legal news sources has not yielded specific information regarding the Petitioner's counsel of record. The general search results primarily focus on recent procedural changes at the PTAB, such as the Director's increased role in institution decisions and a shift in IPR filing trends.

Without the petition for IPR2026-00079 or a specific institution decision, which would typically name the counsel, the identities of the attorneys representing the Petitioner cannot be definitively determined from publicly accessible information at this time. Filings for non-instituted IPRs may not always be as extensively indexed or reported as instituted cases.

The current task is to identify the counsel of record representing the Patent Owner (the equivalent of a "defendant" in a district court case) in IPR2026-00079. As previously established, this is an Inter Partes Review (IPR) at the Patent Trial and Appeal Board (PTAB), not a district court patent infringement case. The case status is "Not Instituted - Procedural," which means the PTAB did not proceed with a full review of the patent's validity.

As of May 29, 2026, a comprehensive search of publicly available PTAB databases and legal news sources, including the USPTO Open Data Portal and Unified Patents portal, for IPR2026-00079 did not yield specific information regarding the Patent Owner's counsel of record. The "Not Instituted - Procedural" status typically indicates that the IPR petition was dismissed on procedural grounds, potentially before a Patent Owner's preliminary response was due or fully evaluated, and thus before formal appearances by Patent Owner counsel might be extensively recorded or widely reported in public databases.

Without the specific docket entry for IPR2026-00079 or a decision that names the Patent Owner and their representatives, the identities of the attorneys representing the Patent Owner cannot be definitively determined from publicly accessible information at this time. Filings for non-instituted IPRs are less frequently indexed or reported in detail compared to cases that proceed to institution and trial.
