Proceedings overview
There are no PTAB proceedings on file for US patent 8484736. This indicates that the patent has not been challenged in an AIA trial proceeding, which means all claims of the patent remain untested by this specific avenue. For a defendant, this means the patent is not hardened by surviving IPRs, nor have any claims been invalidated via PTAB.
Strategic summary
As of today, June 16, 2026, all 23 claims of US patent 8484736 remain patentable and untested by PTAB proceedings. No claims have been canceled, sustained, or otherwise altered by inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) proceedings.
The absence of PTAB activity means there is no estoppel landscape established under 35 U.S.C. § 315(e)(2). Therefore, a defendant currently being asserted against would not be barred from raising any available prior art grounds in a new IPR or other relevant proceeding, assuming they meet the statutory requirements for filing. There is no pattern of filings by any petitioner, nor has the patent owner pursued PTAB appeals. The absence of PTAB challenges for this patent, despite its issue date of July 9, 2013, could be a signal that it has not been extensively asserted, or that prior art challenges were not considered strong enough to warrant an AIA trial.
Recommended next steps
If you are a defendant facing assertion of US patent 8484736, the absence of PTAB activity means a challenge through IPR or other AIA trial proceedings remains an open strategic option. Your legal team should conduct a thorough prior art search to assess the patentability of the claims and determine if a strong petition can be filed. As there are no active proceedings, there are no upcoming trial-stage milestones to consider.
