IPR2026-00083 — [[[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. Levaughn Denton

• Type: Inter Partes Review
• Filed: 2025-11-03

• Judge panel: Not publicly available in the provided information.
• Petition grounds: Not publicly available in the provided information.
• Institution decision: Denied (2026-04-06) — The status indicates a discretionary denial.
• Final Written Decision: Not applicable as institution was denied.
• Settlement / termination: Not applicable as institution was denied.
• Appeal: Not applicable as institution was denied.
• Defensive value: The patent owner successfully defended against this IPR petition, resulting in a discretionary denial of institution.

Strategic summary

All claims of US10656906 are currently SUSTAINED and UNTESTED by a Final Written Decision, as the single IPR filed, IPR2026-00083, was denied institution on discretionary grounds. This means the patent has not been narrowed through PTAB proceedings.

Regarding the estoppel landscape, Samsung Electronics Co., Ltd. et al. (and their privies) are likely barred by § 315(e)(2) from raising any ground they raised or reasonably could have raised in IPR2026-00083. For other potential defendants, all prior-art grounds remain available as there has been no institution or final written decision on the merits of the patentability challenges. The absence of an instituted IPR means the patent claims have not been formally adjudicated for patentability against prior art by the PTAB.

The filing of IPR2026-00083 by Samsung Electronics Co., Ltd. et al. indicates that at least one entity found the patent to be of sufficient concern to warrant a challenge. However, the discretionary denial suggests that the petition itself may have had procedural or substantive weaknesses that led the Board to decline review, rather than a full affirmation of the patent's merits.

Recommended next steps

As a defendant, it is important to understand the specific reasons for the discretionary denial of IPR2026-00083. While the detailed reasoning is not available in the provided information, obtaining the institution decision for IPR2026-00083 from the USPTO PTAB Decisions portal would be a critical first step to understand the Board's rationale and identify any potential weaknesses in the petition that could be avoided in a new challenge.
