Patent Disputes

Patents allow businesses to safeguard their innovations. But when patent disputes arise, they can be substantively and legally complicated and may involve multiple tribunals. Patent holders who must enforce their patents in federal district courts are increasingly required to overcome invalidity challenges before the Patent Trial Appeal Board (PTAB), which is part of the U.S. Patent and Trademark Office.

PTAB challenges can involve inter-partes review, post-grant review, or covered business method review. Petitioners bring PTAB challenges because they can be an efficient way to defeat patent claims earlier in the process than traditional litigation. Therefore, experienced patent litigation counsel must handle these disputes.

Dunlap Bennett & Ludwig has extensive experience representing patent holders in federal district court, PTAB proceedings, federal appellate courts, and International Trade Commission proceedings. We were voted one of the Top 100 Intellectual Property Law Firms in the United States by IP Watchdog in 2019.

Our experience in patent litigation

Dunlap Bennett & Ludwig has significant experience litigating and resolving patent disputes in a variety of industries. Our law firm acted as lead amicus counsel in the recent TC Heartland decision, won three preliminary injunctions in federal patent cases over the last few years, and prevailed in a federal appeal where the PTAB had ruled against the underlying patent. We also have a winning record when it comes to federal appeals.

Our law firm has successfully handled patent disputes by staffing federal district court and PTAB proceedings with overlapping attorneys. This saves time, improves efficiency, and creates a team that can take on new developments in the case as a unified front.

All of our patent litigators are registered patent attorneys and have a deep understanding of patent law and procedure. They have engineering backgrounds and can understand complex technology, cross-examine technical experts, and turn complicated information into stories that engage federal district court and PTAB judges.
