PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Proceedings overview
There are no AIA trial proceedings on file for US patent 11632413. This indicates that the patent has not been challenged through inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) review at the Patent Trial and Appeal Board (PTAB) as of May 29, 2026. This means all claims of the patent are currently untested by PTAB proceedings, leaving them open to challenge.
Strategic summary
All claims (claims 1-15) of US patent 11632413 remain untested by AIA trial proceedings at the PTAB. This means there is no estoppel landscape established through prior PTAB decisions, and all prior art grounds (e.g., under § 102 or § 103) are theoretically available for a new petitioner to assert in a future IPR or PGR, assuming statutory timing requirements are met. The absence of PTAB challenges for a patent issued in April 2023 suggests either that the patent has not yet been widely asserted, or that potential challengers have not identified strong grounds for invalidation via PTAB proceedings.
Recommended next steps
Since there is no PTAB activity on file for US11632413, a defendant facing assertion of this patent would start with a blank slate regarding PTAB challenges.
- Evaluate prior art: Conduct a thorough prior art search to identify potential grounds for invalidation, focusing on novelty (§ 102) and obviousness (§ 103), which are the permissible grounds for IPRs. Given the patent's focus on adaptive bitrate streaming and smoothing quality transitions, prior art in multimedia streaming, network protocols, and video processing would be particularly relevant.
- Consider filing an IPR petition: If strong prior art is found, filing an IPR petition could be a viable defensive strategy. The statutory deadline for filing an IPR is one year from the date of service of a complaint alleging infringement of the patent (35 U.S.C. § 315(b)).
- Monitor for future filings: Continuously monitor PTAB dockets for any newly filed petitions against US11632413, as this landscape can change rapidly once a patent begins to be asserted.
- Review claim scope: Carefully analyze the independent claims (1, 13, 14, 15) and their dependent claims to understand the full scope of protection and to identify any potential weaknesses that could be exploited in an IPR.
