Prosecuting patent applications before the Patent and Trademark Office is a substantial part of the firm’s practice. Our partners are widely recognized experts in this area. Legal issues in our cases involve questions of validity, infringement, and enforceability. In addition to obtaining and litigating U.S. patents, our attorneys prepare patent validity and infringement opinions, obtain patents under the laws of many foreign countries, and prepare and negotiate contracts for the exploitation and protection of patented and unpatented ideas, products, and services.
