Protecting Intellectual Assets
We routinely interact with patent and trademark examiners in the U.S. Patent and Trademark Office, and secure and protect intellectual property rights around the world. Andrews Kurth intellectual property lawyers speak the business and technical languages of our clients. The whole focus of our IP counsel is securing for clients the maximum competitive advantage from effective exploitation and protection of their intellectual assets.
