David Kellis, a shareholder, practices in the areas of patent preparation, prosecution, and considered counseling on portfolio development and protection strategies.  David helps his clients realize the full potential of their intellectual property. “I work to provide options for my clients,” he says, “to give them the greatest flexibility to make decisions that implicate their intellectual property down the road.”  David’s experience spans multiple technology categories, including access control, aerospace, clean energy, consumer electronics, displays, LIDAR, medical devices, power machinery, RFID, software, textiles, vehicles, and vehicle wheels, among others.

In addition to securing domestic and international patent protection for his clients, David prepares patent validity, patent infringement, and freedom to operate opinions, and drafts technology-related agreements, including licensing agreements, collaborative development agreements, software agreements, and nondisclosure agreements.

David draws upon his experience with all phases of litigation in advising his clients. He has argued motions and participated in jury and bench trials; worked closely with technical experts, including concerning the preparation and defense of expert reports; taken and defended depositions around the country; and authored numerous pleadings, briefs, settlement agreements, and other litigation-related documents. “Litigation is where the rubber meets the road for patent rights, and the possibility of future litigation should inform decisions made early on in the patent lifecycle.  An understanding of how litigation works, not just in theory but in practice, facilitates better advice and better decision-making.”

David has taught patent law as an adjunct professor at the University of Colorado.  Before joining Sheridan Ross, David worked in the Colorado office of a national law firm. He also clerked for the Honorable Henry Coke Morgan, Jr. of the United States District Court for the Eastern District of Virginia, where he worked on both civil and criminal matters. David is currently working on a master’s in business administration, which will allow him to better understand his clients’ business needs and counsel clients within the context of those needs.
