David Clonts provides strategic guidance and counseling in all aspects of intellectual property and technology protection and disputes, including patent and technology litigation, technology transactions, licensing, and inter partes reviews, with a special focus on the technology, medical device, and telecommunications sectors. Having worked as a programmer and engineer prior to beginning his legal career, David offers the firsthand experience and knowledge needed to speak with authority to technical experts, engineers, the jury, and the court.
