David J Cushing

I am a partner in the Washington, D.C. office of Sughrue Mion, PLLC, where for over thirty-five years I have engaged in all facets of patent related matters, including prosecution, opinions on infringement and validity issues, licensing, litigation, ex parte and inter partes reexamination practice, post-grant and inter partes review, and Federal Circuit appeals.  My practice has covered a wide range of electrical, mechanical, optical, computer science and medical device technologies, with particular focus and extensive experience in hearing aids, telecommunications, networking systems, and computer system architecture, for both U.S. and international clients.  My clients range from individuals wanting to protect their ideas, technology start-ups and other small companies requiring freedom to operate and design review counseling and development of an overall intellectual property plan, and Fortune 100 companies with in-house intellectual property counsel seeking assistance in all areas. 

I graduated from the University of Notre Dame in 1973 with a degree in Electrical Engineering, and am a 1976 graduate of the University of Maryland School of Law.   I registered to practice before the U.S. Patent and Trademark Office, and am admitted to practice in the state of Maryland and the District of Columbia.  I am a member of the Court of Appeals for the Federal Circuit, and the Supreme Court of the United States.
