By gaining a thorough understanding of and focusing on your overall trademark and branding strategy, we provide advice on deal structures, branding strategies and enforcement experience to help identify and avoid pitfalls, while maximizing brand value.

Our attorneys have prepared and filed thousands of state and federal trademark applications. We coordinate the registration of marks in countries around the world. We also help establish branding and policing programs, usage guidelines and provide guidance on infringement issues.

We assist our clients in enforcing or defending their valuable trademarks or domain names. We enforce and respond to issues and conduct of negotiations on issues of infringement or other violations. We have also initiated or defended a wide range of administrative and court proceedings to enforce our clients' trademarks, trade dress and domain names. We handle the opposition and cancellation of third-party trademark applications and registrations before the Trademark Trial and Appeal Board of the United States Patent and Trademark Office. In addition, we have also defended clients against claims that their trademarks, trade names and domain names may be confusingly similar to third-party trademarks or trademark registrations.
