Polsinelli has one of the most experienced trademark, advertising and design litigation practices in the U.S. Over the last 10 years, Polsinelli’s group has handled hundreds of trademark, advertising and design cases in federal courts from coast to coast. In addition, our attorneys regularly represent clients in arbitrations, in the Courts of Appeals, and in administrative proceedings such as those pending in front of the United States Patent and Trademark Office Trademark Trial and Appeal Board (“TTAB”), the Patent Trial and Appeal Board (“PTAB”) and the International Trade Commission (“ITC”). We have deep experience across a broad range of industries, from small brick-and-mortar retail establishments to large, multinational technology companies. Our clients are similarly diverse, ranging from small startup companies up to some of the largest, well-known brands in the world.

Polsinelli both enforces and protects brands and designs while defending against frivolous or overreaching enforcement efforts of others. We handle matters ranging from simple cease and desist letters to developing complex anti-counterfeiting and policing programs. We have represented clients in administrative matters such as those dealing with exclusion orders in the ITC, challenging and defending trademark registrations before the TTAB and the seizure of counterfeit goods by the U.S. Customs and Border Patrol. We are also adept at handling cross-border cases, as well as working with local counsel to handle matters in foreign countries around the world. Matters include claims arising from:

  • Trademark and trade dress infringement
  • Trademark dilution
  • False and misleading advertising
  • Design patent infringement
  • Domain name disputes
  • Unfair competition
  • Anti-counterfeiting and black market goods
  • Cybersquatting and domain issues
  • Trademark licensing disputes
  • Border-seizures

Over the years, design patents have become hotly litigated in diverse industries including user interfaces, consumer products, fashion, medical equipment and mechanical devices. This is in part because of their broad application to numerous products, but also because of the additional damages generally unavailable in regular utility patent disputes. Polsinelli has extensive experience representing clients in design patent cases.
