Proceedings overview
As of May 31, 2026, there are no publicly available records from the USPTO Open Data Portal or general web searches indicating any AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method review) against US Patent 10,523,350. Therefore, all claims of the patent remain untested by PTAB challenges.
Strategic summary
Currently, all claims of US 10,523,350 are UNTESTED by AIA trial proceedings. This means that a potential defendant has full flexibility in bringing any available prior art grounds, including those that were or could have been raised in a PTAB petition, without facing estoppel under 35 U.S.C. § 315(e)(2). The absence of PTAB activity can be a signal, as well-asserted patents often become targets for IPRs. Given the recent litigation filing by ContentNexus LLC in April 2026, it is possible that PTAB petitions may be filed in the near future.
Recommended next steps
If facing assertion of US 10,523,350, a potential defendant should consider initiating an AIA trial proceeding (e.g., an Inter Partes Review) to challenge the patentability of the asserted claims. The prior art analysis provided previously, particularly the U.S. Patent No. 4,025,851 to Haselwood et al., suggests strong grounds for challenging claims related to embedding instructions in the vertical blanking interval to trigger operations (e.g., Claim 49 and Claim 112). A detailed analysis of the patent claims against known and newly discovered prior art would be crucial to identify the strongest grounds for a petition.
