Proceedings overview
There are no AIA trial proceedings on file for US patent 8915829. This indicates that the patent has not yet faced challenges through inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) review at the Patent Trial and Appeal Board (PTAB). For a defendant, this means the patent's claims are currently untested in an AIA trial setting, and therefore, an IPR-based defense remains a viable option.
Strategic summary
As there are no PTAB proceedings on file for US patent 8915829, all claims of the patent remain untested by AIA trial procedures. This means no claims have been canceled or sustained through PTAB review. Consequently, the estoppel provisions of 35 U.S.C. § 315(e)(2) do not currently apply to any potential petitioner. All prior-art grounds remain available for future challenges, should they arise. The absence of PTAB activity could suggest several things: the patent may not have been widely asserted in litigation, the asserted claims may be considered strong by potential petitioners, or it may simply not yet have attracted the attention of entities that frequently file IPRs.
Recommended next steps
Since there is no PTAB activity for US patent 8915829, a defendant currently facing assertion of this patent has a clear path to consider an AIA trial challenge. The absence of prior art grounds being tested means that a comprehensive prior art search and analysis could identify strong grounds for an IPR petition.
