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 (Inter Partes Review, Post-Grant Review, or Covered Business Method) currently on file for US Patent 9846887, nor were any surfaced through web search. This indicates a strong defensive posture for a defendant, as the patent claims have not been challenged or narrowed at the PTAB.
Strategic summary
As there are no PTAB proceedings on file for US Patent 9846887, all claims of the patent (claims 1-20, as listed in the patent text) remain untested and are presumed valid. There is no estoppel landscape established by prior PTAB trials. This means that a potential challenger would have the full range of prior art grounds under 35 U.S.C. §§ 102 and 103 (for IPRs) or additional grounds under 35 U.S.C. §§ 101, 112 (for PGRs, if applicable) available to them if they chose to file a petition. The absence of PTAB activity suggests that the patent has not yet been significantly asserted in litigation, or that prior assertions have not prompted an IPR challenge.
Recommended next steps
Since no PTAB activity exists for US Patent 9846887, a defendant facing assertion of this patent would start from a clean slate regarding PTAB challenges.
- Evaluate prior art: Conduct a thorough prior art search to assess the patentability of the asserted claims under 35 U.S.C. §§ 102 and 103. This is a critical step to determine the viability of an IPR petition.
- Monitor for future PTAB filings: Keep an active watch on PTAB filings for US Patent 9846887 through the USPTO's P-TACTS system, as new petitions can be filed at any time, subject to statutory deadlines.
- Consider filing an IPR: If strong prior art is identified, initiating an IPR could be a strategic move to challenge the patentability of the claims. The decision to file should weigh the potential costs, benefits, and the specific facts of the alleged infringement.
