Proceedings overview
There are no AIA trial proceedings on file for US patent 6,961,310 as of the most recent ingest from the USPTO ODP API, and no additional proceedings were found via web search. This indicates that the patent has not been subjected to IPR, PGR, or CBM challenges, which provides a defendant with a less "hardened" patent to potentially challenge through such avenues.
Strategic summary
As of today, May 29, 2026, all claims of US patent 6,961,310 are UNTESTED by AIA trial proceedings. The absence of PTAB activity means there is no estoppel landscape established under § 315(e)(2). Therefore, a defendant being asserted against this patent would have all prior-art grounds available to them for a potential IPR challenge. There are no patterns of aggressive PTAB appeals by the patent owner or involvement of defensive aggregators like Unified Patents to report.
Recommended next steps
Since no PTAB activity exists for US6961310, a defendant facing assertion of this patent should consider initiating an Inter Partes Review (IPR) to challenge the patent's validity. This patent has not been subjected to the scrutiny of an AIA trial, meaning its claims have not been previously vetted and confirmed as patentable by the PTAB. The absence of prior challenges suggests that an IPR could be a viable defense strategy.
