The FRL team has deep experience in proceedings before the Patent Trial and Appeal Board in the United States Patent Office, regularly ranking among the most active law firms at the patent venue. We regularly represent patent owners, including our clients in district court and ITC matters, in inter partes review and ex parte reexamination proceedings.
Our team has been ranked consistently among the top 20 “busiest” PTAB groups in the United States by Legal Metric, involved in more than 100 proceedings annually for both patent owners and petitioners.
