One of the nation’s largest full-service intellectual property law firms, Cantor Colburn is ranked the #3  U.S. utility patent law firm by IP Law360, and the fastest growing patent law firm by Juristat. By providing strategic counsel on all aspects of intellectual property law, we help our clients enjoy maximum benefits from their valuable intellectual property assets.

We routinely are asked by our clients to provide opinions with regard to pending patents and patent applications. These opinions vary from validity, infringement, non-infringement, and clearance or right-to-practice issues, to ensure that our clients are able to navigate existing patent portfolios as well as enforcing their own patent portfolios. We provide a tailored and balanced approach to each individual client’s needs in order to avoid unnecessary time and money developing new products.

We are invested in the success of a diverse group of clients, ranging from high-tech start-ups to some of the largest companies in the world. Many of these clients are industry leaders who entrust us with their patent opinion work, knowing that our focused approach supports their efforts to bring new products to market with minimal risk of infringement.

Training in a wide number of technologies gives our attorneys the insight and perspective needed to provide clients in cutting-edge industries such as biotechnology, pharmaceuticals, chemicals, computer science, and telecommunications with strategic, informed counsel. By combining legal experience with technical knowledge, they are uniquely able to generate opinions that align precisely with individual client business objectives.

We prepare opinions in a number of sizes and formats, ranging from memos and relatively short letters to summary opinions, which include extensive and detailed analyses with multiple exhibits, as called for by the specific situation.
