A post-grant powerhouse.

Post-grant proceedings are an integral component of any comprehensive patent strategy, and Fish & Richardson is the undisputed leader in post-grant practice. Working with both petitioners and patent owners, our post-grant team has handled more proceedings than any other firm at the Patent Trial and Appeal Board. Fish is consistently ranked as the preeminent practice at the PTAB, we host the most innovative educational programs, and we are a founding and active member of the PTAB Bar Association.
