Intellectual Property and Technology Law

DiMuroGinsberg understands what makes innovative companies tick. Our intellectual property (IP) lawyers are experienced and effective advocates with a pragmatic perspective informed by years of complex litigation experience involving a wide range of technologies and a keen understanding of the business world.

Led by Bernard J. DiMuro, Cecil E. Key, and Jay P. Kesan, our full-service IP practice is uniquely situated to advise clients working in dynamic industries where technology is rapidly advancing and the legal environment may be uncertain.

The IP attorneys of DiMuroGinsberg are widely recognized leaders in the IP world. Combined they have tried hundreds of cases serving as litigation and appellate counsel in federal district courts, before the International Trade Commission, (ITC) and before various U.S. Courts of Appeal. The DG Key IP team works diligently to minimize each client’s risks associated with litigation while providing top tier transactional representation. They serve clients in the areas of patent, trademark, copyrights and trade secrets.

Our attorneys have testified before Congress and the U.S. Patent and Trademark Office (USPTO) about developing IP issues; lectured at top universities; and been widely published in national newspapers, legal periodicals and peer-reviewed scientific journals. Our experience and contacts in government, academia and industry give us multi-faceted insights into the legal problems that our clients face when seeking to protect and capitalize on their valuable intellectual assets.

In addition to our record of success in representing clients before state and federal courts, the USPTO and the ITC, we draw on decades of experience in serving on the boards of entrepreneurial startups, working as scientists and engineers, and advising some of the world’s most successful technology companies.
