Polsinelli’s Intellectual Property & Technology Litigation Practice takes a creative, strategic, and cost-effective approach to resolving intellectual property disputes for local, regional, national and global companies and individuals. The practice was recently named one of four 2016 "IP Powerhouses" in the nation by BTI Litigation Outlook. 

Across the firm's broader Intellectual Property practice that includes both transactional and litigation services, in 2016 we became one of the largest IP practices in the nation, with nearly 120 attorneys, patent agents and scientists dedicated to helping our clients solve their most complex issues related to the establishment and protection of their intellectual property.

On a national level, attorneys in the Intellectual Property & Technology Litigation practice have handled all stages of intellectual property litigation, including jury trials and appeals, and have trial experience in patent, trademark, copyright, false advertising, trade dress, trade secrets and unfair competition matters throughout the United States. We frequently litigate patent cases in the District of Delaware, the Eastern District of Texas, the Northern District of California, the Northern District of Illinois, and the International Trade Commission. Our attorneys have decades of collective experience in the highly-specialized area of Paragraph IV litigation under the Hatch-Waxman Act in key venues, and are experienced in all aspects of pharmaceutical technology. To achieve the best possible result for our clients, our trial lawyers collaborate with experienced patent prosecutors and scientists who have significant experience in technologies such as pharmaceuticals, medical devices, electronics, computer software, chemical processes, telecommunications, and mechanical devices.

We are devoted to intellectual property law, effectively enforcing and defending our clients’ rights in courts and other dispute resolution forums.
