David E. Wigley, Ph.D.: Attorney with Eversheds Sutherland (US) LLP


David Wigley, Ph.D. combines his legal experience with years of academic research in chemistry to develop intellectual property strategies that protect both established and fledgling businesses. David focuses mainly on the IP rights of companies involved in chemical, pharmaceutical, materials-related and polymer technologies. Based in Eversheds Sutherland (US)’s Intellectual Property Practice Group, he works to secure, maintain, license and enforce the IP rights of clients. His track record includes prosecuting patent applications and developing opinions regarding validity/invalidity, infringement/non-infringement and freedom to operate issues.

David, a former professor of chemistry at the University of Arizona, was research director of a program in chemical synthesis and catalysis funded by the U.S. Department of Energy and the National Science Foundation. That experience allows David to leverage a broad understanding of the technology industry and develop IP strategies that align perfectly with the client’s business strategies. He also has proven to be instrumental in IP due diligence related to his clients’ corporate transactions. David is registered to practice before the U.S. Patent and Trademark Office.
