PTAB challenges

Proceedings overview

There is currently one active Inter Partes Review (IPR) proceeding on US Patent 10,313,077, which has been instituted and is currently in the trial phase. This means that the patent's claims are actively being challenged, and no claims have been invalidated or sustained by a Final Written Decision yet, leaving the ultimate defensive posture uncertain.

IPR2025-01069 — [[[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) et al.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.%20et%20al.) v. Wilus Institute of Standards and Technology Inc.

• Type: Inter Partes Review
• Filed: 2025-06-05
• Status: Trial Instituted. The PTAB has decided to proceed with a trial on the merits of the challenges.
• Judge panel: The specific judge panel information for this IPR is not publicly available yet through the provided sources as of the latest update.
• Petition grounds: The petition was filed by Samsung Electronics Co., Ltd. et al. against claims of US10313077. The specific claims challenged, prior art references cited, and statutory bases (§ 102 for novelty and/or § 103 for obviousness) are typically detailed in the institution decision. This information is not explicitly provided in the initial prompt or readily available in a summary form without accessing the institution decision document.
• Institution decision: Instituted. The petition was granted a trial, indicating that Samsung Electronics Co., Ltd. et al. demonstrated a reasonable likelihood that at least one challenged claim is unpatentable. The institution decision would outline the specific claims and grounds for which trial was instituted. The exact date of institution is not provided in the prompt but occurred sometime before the "last modified" date of 2026-04-01.
• Final Written Decision: Not yet issued. The proceeding is still in the trial phase.
• Settlement / termination: No settlement or termination has been publicly reported; the IPR remains active.
• Appeal: Not applicable, as no Final Written Decision has been issued.
• Defensive value: This active IPR creates uncertainty regarding the validity of the challenged claims. A defendant facing assertion of this patent will need to monitor this proceeding closely, as an invalidation of claims would significantly weaken the patent owner's position. Conversely, if claims are sustained, it would strengthen the patent's validity against similar challenges.

Strategic summary

Currently, all claims of US 10,313,077 are "untested" by a final written decision from the PTAB. IPR2025-01069 is in the trial stage, meaning a decision on the merits of the challenged claims is pending. Until a Final Written Decision is issued, the full scope of which claims might be canceled or sustained remains unknown.

The estoppel landscape will only take effect after a Final Written Decision. If a Final Written Decision eventually issues and finds certain claims unpatentable, Samsung Electronics Co., Ltd. et al. (and their privies) would be estopped under § 315(e)(2) from asserting invalidity grounds they raised or reasonably could have raised in the IPR regarding those claims. For other potential defendants, the prior art grounds raised by Samsung in this IPR remain potentially available until a FWD is issued; however, they may be influenced by the outcome of this IPR.

Regarding pattern signals, only one IPR has been filed on this patent, and it is still active. Unified Patents, a defensive aggregator, is listed as having provided "Unified Patents PTAB Data" for this case, suggesting their involvement in tracking or potentially facilitating the challenge.

Recommended next steps

As IPR2025-01069 is active and instituted, a defendant should closely monitor the proceeding. Key upcoming milestones include the oral hearing (if requested) and, most importantly, the statutory one-year deadline for the Final Written Decision from the date of institution. While the exact institution date isn't provided in the prompt, the last modified date of 2026-04-01 indicates the trial is well underway. Accessing the publicly available documents for IPR2025-01069 on the USPTO PTAB E2E system (https://portal.unifiedpatents.com/ptab/case/IPR2025-01069) is crucial to determine the specific claims challenged, the prior art asserted, the institution decision date, and the PTAB's reasoning for instituting the trial. This information will inform any defensive strategy against US 10,313,077.
