Post-Grant
We use post-grant tools strategically to both challenge and defend patents on behalf of our clients.
Attorneys who practice at the PTAB must be skilled in both patent prosecution and patent litigation, as inter partes review and post-grant review combine elements of both practices. Fish’s post-grant practice group – which sits at the intersection of our top-ranked patent prosecution and patent litigation practices – excels in this forum. Fish has handled more proceedings at the PTAB than any other firm, making us well-positioned to win for our clients across all technologies.
Our attorneys do more than merely react to changes in the post-grant legal landscape; in many cases, we have pioneered new law that has had far-reaching impacts on post-grant practice nationwide.
Commensurate with our role as thought leaders in post-grant jurisprudence, we offer a number of innovative educational tools, including:
- Post-grant for practitioners, a series of webinars covering post-grant topics, including recent decisions, lessons learned, and practice tips and trends
- Fish post-grant radio, a series of podcasts covering developments in post-grant jurisprudence and related practice tips
- Annual post-grant report, a yearly report that examines significant case law and decisions by the PTAB and Federal Circuit, as well as trends and statistics concerning post-grant practice over the previous year
- Detailed case summaries, alerts, and news, including exclusive commentary and insights from members of our post-grant team
Clients come to Fish when they need to win at the PTAB.
We have been closely involved in the development of post-grant law since its inception. Our clients come to us because they know that we can craft novel, persuasive, and legally sound arguments that win at the PTAB and hold up in the Federal Circuit. We have represented a broad range of clients of all sizes and in all industries and have handled nearly every issue conceivable in post-grant law. Always at the cutting edge of the practice, our attorneys have been involved in some of the highest profile, precedent-setting post-grant matters ever heard at the PTAB.
Our post-grant practice is the perfect marriage of our preeminent patent prosecution and patent litigation practices.
Our skill in patent prosecution – filing an average of over 8,900 U.S. patent applications per year – allows us to capitalize on our detailed knowledge and understanding of the USPTO’s policies and procedures. Our extensive patent litigation practice – one of the most active nationwide – allows us to incorporate lessons learned over the course of over 140 years into our PTAB strategies. We also seamlessly coordinate post-grant proceedings with co-pending litigation, designing and implementing holistic strategies for success that take into account stays, estoppel, and discretionary denials. Many clients continue to work with us when appeals to the Federal Circuit are necessary, and we are often hired to handle post-grant appeals when a new perspective is needed.
When it comes to post-grant, Fish is unmatched.
