Strategic summary

As of today, May 22, 2026, IPR2025-01422 is the only AIA trial proceeding on record for US patent 10751029. This proceeding is currently in the "Trial Instituted" phase, meaning the PTAB has determined that the petitioner, Caption Health, Inc. et al., has a reasonable likelihood of prevailing on at least one of the challenged claims. Consequently, the claims challenged in this IPR are currently undergoing scrutiny for patentability.

The estoppel landscape will depend on the eventual outcome of IPR2025-01422. If a Final Written Decision is issued that invalidates claims, the petitioner (Caption Health, Inc. et al.) and its privies would be estopped under § 315(e)(2) from asserting invalidity grounds that were raised or reasonably could have been raised in the IPR. For a new defendant, this means that prior-art grounds not asserted or instituted in this IPR may still be available for a future challenge. Without knowing the specific claims challenged and the prior art used, it's impossible to determine precisely which prior-art grounds remain available.

There is no discernible pattern of multiple IPRs by the same petitioner or aggressive PTAB appeals by the patent owner at this time, as only one proceeding is on file and it is still active. Unified Patents is listed as the petitioner in the PTAB case information, indicating a defensive aggregator is involved in this challenge.

Recommended next steps

As IPR2025-01422 is an active proceeding, a defendant should:

• Monitor the PTAB E2E system for updates on IPR2025-01422, specifically for the institution decision details (which claims were instituted and on what grounds) and the expected due dates for the oral hearing and the Final Written Decision. The PTAB typically issues a Final Written Decision within one year of institution.
• Once the institution decision is publicly available, analyze the instituted claims and grounds to understand the scope of the challenge.
• If the Final Written Decision invalidates claims, obtain the FWD from the USPTO PTAB Decisions portal (https://developer.uspto.gov/ptab-documents) and incorporate the findings into any defense strategy against assertions of US10751029.
