What Is Post-Grant Review?

A post-grant review, or PGR, is a trial proceeding where the patentability of one or more claims in a patent is reviewed.

The Patent Trial and Appeal Board (PTAB) is the branch of the U.S. Patent and Trademark Office that handles the trial proceeding. The post-grant review can be filed on any grounds that are available to dispute the validity of a patent claim, except for the following: failure to disclose the best mode requirement....Read more
