PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US Patent 11184652, which is currently pending institution. This gives a defendant a nuanced defensive posture; while no claims have been invalidated, the patent is actively being challenged, suggesting a potential future narrowing of scope if the IPR proceeds to trial and a Final Written Decision.

IPR2026-00366 — Pinterest, Inc. v. OpenTV Inc.

• Type: Inter Partes Review
• Filed: 2026-05-22
• Status: Pending. The petition has been filed, and the PTAB will now determine whether to institute the inter partes review.
• Judge panel: Not yet publicly available or assigned, as the proceeding was very recently filed.
• Petition grounds: Not yet publicly available from a general search, as the proceeding was very recently filed. These details are typically contained within the petition, which is not immediately indexed in detail by public search engines for new filings.
• Institution decision: Not yet issued. A decision on institution is typically due within six months of the filing date.
• Final Written Decision: Not yet issued, as the proceeding has not been instituted.
• Settlement / termination: Not applicable at this early stage.
• Appeal: Not applicable at this early stage.
• Defensive value: This proceeding indicates that Pinterest, Inc. is challenging the patent. For a defendant facing assertion of this patent, it signals a potential vulnerability in the patent, and the outcome of this IPR could significantly impact the patent's enforceability. However, as it is currently pending, no claims have been invalidated or confirmed patentable, so the direct defensive value for specific claims is yet to be determined.

Strategic summary

Currently, all claims of US Patent 11184652 remain UNTESTED by a Final Written Decision in a PTAB proceeding. The patent has not been narrowed through IPR.

The estoppel landscape is currently limited. If the IPR (IPR2026-00366) is instituted and proceeds to a Final Written Decision, Pinterest, Inc. (and its privies) would be estopped under 35 U.S.C. § 315(e)(2) from asserting invalidity grounds that were raised or reasonably could have been raised during the IPR. For a defendant currently being asserted against, this means that prior-art grounds not raised in the IPR, or those that could not have been reasonably raised (e.g., due to different legal standards or newly discovered art), would still be available. As the IPR has just been filed, the specific prior art and statutory bases challenged by Pinterest are not yet publicly known without access to the full petition.

There are no clear pattern signals at this extremely early stage, as only one IPR has been filed on the patent. This is the first known IPR filed against US11184652, with Pinterest, Inc. as the petitioner.

Recommended next steps

As IPR2026-00366 is pending, the key milestone to watch is the institution decision deadline, which is approximately 2026-11-22 (six months from the filing date of 2026-05-22). If the IPR is instituted, then the trial stage will begin, with a Final Written Decision generally due one year after institution.

It is advisable for a defendant to monitor the progress of IPR2026-00366. Accessing the petition, once it becomes publicly available in the USPTO PTAB E2E system, would provide crucial details regarding the claims challenged, the prior art relied upon, and the specific invalidity grounds asserted by Pinterest, Inc. This information would be vital for understanding the potential impact on the patent's claims and informing any defensive strategy.

There is one AIA trial proceeding on file for US Patent 11184652, which is currently pending institution. This means no claims have been invalidated or sustained by the PTAB yet. While the patent is actively being challenged, the bottom-line defensive posture is that the patent's claims remain untested by an IPR Final Written Decision.

IPR2026-00366 — Pinterest, Inc. v. OpenTV Inc.

• Type: Inter Partes Review
• Filed: 2026-05-22
• Status: Pending. The petition has been filed, and the Patent Trial and Appeal Board (PTAB) will now evaluate whether to institute the inter partes review.
• Judge panel: The judge panel has not yet been publicly assigned for this recently filed proceeding.
• Petition grounds: The specific claims challenged, prior art asserted, and statutory bases (§ 102 / § 103 / § 112) are not yet publicly available through general search results for this newly filed IPR. These details would typically be found in the full petition filed with the PTAB.
• Institution decision: Not yet issued. The PTAB typically issues a decision on institution within six months of the petition's filing date.
• Final Written Decision: Not yet issued, as the proceeding has not been instituted.
• Settlement / termination: Not applicable at this very early stage of the proceeding.
• Appeal: Not applicable at this stage.
• Defensive value: This active IPR signals that Pinterest, Inc. is challenging the validity of US Patent 11184652. For a defendant facing assertion of this patent, it indicates a potential vulnerability in the patent's claims. However, since the proceeding is in its earliest stages, no claims have been definitively invalidated or upheld, so the direct defensive value for specific claims is not yet established.

Strategic summary

All claims of US Patent 11184652 are currently UNTESTED by a Final Written Decision in a PTAB proceeding. The patent's scope has not been narrowed through IPR.

The estoppel landscape is presently limited. If IPR2026-00366 is instituted and reaches a Final Written Decision, Pinterest, Inc., and parties in privy with it, would be estopped under 35 U.S.C. § 315(e)(2) from asserting invalidity grounds that were raised or reasonably could have been raised in the IPR. For a defendant currently facing assertions, this implies that prior-art grounds not included in this IPR (or those that could not have been reasonably raised) would still be available for a challenge. As the IPR has just been filed, the specific grounds and prior art being challenged by Pinterest are not yet publicly known.

There are no discernible pattern signals at this time, as IPR2026-00366 is the sole recorded PTAB proceeding for this patent. The petitioner, Pinterest, Inc., is initiating the first known IPR challenge against OpenTV Inc.'s patent 11184652.

Recommended next steps

Given that IPR2026-00366 is an active and pending proceeding, the critical upcoming milestone is the institution decision deadline, which is expected around 2026-11-22 (six months from the filing date of 2026-05-22). If the IPR is instituted, a trial will commence, with a Final Written Decision typically due within one year of institution.

For a defendant interested in this patent, it is recommended to closely monitor the progress of IPR2026-00366. Accessing the full IPR petition via the USPTO PTAB E2E system, once available, is essential to understand the specific claims being challenged, the prior art cited, and the invalidity arguments made by Pinterest, Inc. This information will be crucial for evaluating the strength of the patent and formulating a robust defensive strategy. There is no Final Written Decision to quote or link to at this juncture.
