Strategic summary

All claims of US patent 10823576 remain untested in AIA trial proceedings, as the sole filed IPR (IPR2025-01603) was denied institution. The patent has not been narrowed through IPR.

Regarding the estoppel landscape, pursuant to 35 U.S.C. § 315(e)(2), Avidbots Corporation (the petitioner in IPR2025-01603) and its privies are estopped from asserting in any other USPTO proceeding or in any civil action any ground that they raised or reasonably could have raised during the IPR. This means that if a defendant being asserted against is Avidbots Corporation or in privity with them, they would be barred from using the prior art grounds presented in IPR2025-01603. For other potential defendants, the specific prior-art grounds are not publicly available in the provided data.

There are no apparent pattern signals such as multiple IPRs filed by the same petitioner on this patent or aggressive PTAB appeal strategies by the patent owner, given the single proceeding and its disposition. The petitioner, Avidbots Corporation, is listed in the proceeding.

Recommended next steps

Since IPR2025-01603 was denied institution, there are no active trial-stage milestones. The absence of instituted PTAB activity means that the claims of US10823576 have not been subject to a full review by the PTAB. Potential defendants not estopped by IPR2025-01603 may consider filing their own IPR petition if relevant prior art is identified.
