As a general intellectual property lawyer, Dennis has a wealth of experience in working through complex issues and developing a comprehensive strategy that helps his clients meet their goals. As importantly, he is committed to communicating that strategy to his clients so they're better able to make informed business decisions.

Dennis is a shareholder in Merchant & Gould's Minneapolis office. He counsels a wide range of business clients from sole inventors and medium size companies to multinational corporations with extensive, worldwide patent estates. He counsels his clients on intellectual property issues relating to the development and strategic protection of products in the United States and abroad, handling infringement issues, contested matters, and licensing.

Dennis has considerable experience in preparing patent applications, handling clearance and infringement issues, and licensing. He also manages contested matters, including a very large number of European patent oppositions, and handles United States patent reexamination and interference matters. Prior to becoming an attorney, Dennis worked as a patent examiner at the U.S. Patent and Trademark Office, where his technical area of responsibility included polymer materials. This insider's edge helps him understand the burdens and obligations of the patent examiners and craft applications that are favorable to his clients' interests.

Dennis has considerable experience in the chemical engineering and chemistry technologies, including cleaning technologies, paper manufacture and processing, polymer chemistry and polymer processing techniques, detergents and surfactants, polymerization, extraction, distillation, water purification, metallurgy, paints, and adhesives. Areas of experience in the mechanical arts include medical devices, automotive accessories, material handling equipment, filters, and refrigeration systems.

Dennis represents children pro bono on behalf of the Children's Law Center of Minnesota. He is married and spends most of his spare time attending and participating in the various sports and activities of his four children.
