Arnold & Porter has extensive experience advising clients on the strategies and options available to both patent owners and petitioners in post-grant proceedings. These procedures provide faster approaches to evaluate patent validity, as well as strategic tools that can both limit and define issues before or during patent litigation and promote settlements. We cover all USPTO-conducted proceedings—inter partes reviews, post-grant reviews, derivation proceedings, ex parte reexaminations, reissues, and supplemental examinations. Our leading U.S. Patent Office practice, combined with our substantial patent trial experience, makes us well-suited to protect client interests in post-grant proceedings.
