Post Grant Review

Closely mirroring IPR, Post Grant Review has the potential to expand and extend the already profound legacy of IPR.  PGR has a similar format to IPR, but with a higher cost, additional patentability challenges to implement, a more narrow timeframe to file, among other differences.  Many of the lessons of IPR can, therefore, be applied to PGR proceedings.  To date, however, few PGR proceedings have been filed, likely due, at least in part, to the limited population of patents that are eligible for PGR proceedings (only post-AIA) patents.
