Strategic summary
As of 2026-05-29, there are no AIA trial proceedings (IPR, PGR, or CBM) recorded for US patent 9215275 in the USPTO ODP API or found through web search. This means all claims of the patent (claims 1-15) are currently untested by AIA trial proceedings.
The absence of PTAB activity could be a signal that the patent has not been extensively asserted, or that prior art challenging its validity has not yet been identified or brought forth in an AIA trial. For a defendant facing assertion, this means there are no estoppel limitations under § 315(e)(2) from prior AIA trials, and all prior-art grounds remain available for potential challenges, such as in an IPR petition or district court litigation.
Recommended next steps
If facing assertion of US patent 9215275, a defendant should consider a thorough prior art search to identify potential grounds for an AIA trial challenge (e.g., an Inter Partes Review). The absence of prior PTAB challenges means this patent has not yet been "hardened" through such proceedings, potentially making an IPR a viable defensive strategy.
