Intellectual Property Litigation

Intellectual Property Image

When representing clients in the enforcement of their intellectual property rights, our lawyers pursue the most cost-effective approach to resolving disputes based on their understanding of client business needs, legal issues, technical matters, the potential risks and costs of litigation. Our clients include companies and technologies in biotechnology, life sciences, pharmaceuticals, medical and surgical devices, semiconductor manufacturing and computers and software. 

Clients regularly seek our counsel when competition increases in a way that requires legal advice relating to advertising and unfair competition disputes, and when enforcement, cease and desist or defensive actions may be required.  We have extensive experience resolving a wide range of disputes involving trademarks, service marks and domain names, including claims of counterfeiting and infringement. 

We regularly prosecute and defend against claims of: infringement, misappropriation and counterfeiting of all intellectual property assets, including patents, trademarks, trade dress, trade secrets, copyrights, licenses and domain names. We are experienced at handling complex disputes related to ownership, unfair competition and business practices, false advertising, contracts, computer technology and software matters.

We have extensive trial experience before state courts, federal district courts, and the Court of Appeals for the Federal Circuit, and are skilled at handling all phases of litigation, including temporary restraining orders, preliminary injunctions, seizures, declaratory judgment proceedings, trials and appeals.
