David Kellis, a shareholder, practices primarily in the areas of patent preparation, prosecution, and counseling, although a significant portion of his practice is devoted to IP-related agreements. His 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.
Recognizing that every client is unique, David develops and implements a tailored intellectual property strategy for each client’s particular needs. He helps clients identify the specific types of protection that will be most useful for them while taking into account applicable budgetary constraints. As a lawyer with an MBA degree, David understands the complex balancing act his clients must maintain, and he often partners with clients throughout the portfolio development process to identify ways to optimize their portfolios.
In the patent development process, David helps his clients achieve peace of mind by preparing formal opinions regarding patent validity, patent infringement, and freedom to operate opinions. He also assists clients with the development and licensing of intellectual property, in connection with which he frequently drafts licensing agreements, collaborative development agreements, software licensing agreements, nondisclosure agreements, and other technology-related agreements.
In all aspects of client advising, David draws upon his extensive experience with complex litigation, including federal jury trials and appeals. David has a comprehensive understanding of the real-world implications of high-stakes litigation, which informs his advice and decision-making. In the course of representing his clients in patent, trademark, and breach of contract litigation, David has taken or defended dozens of depositions around the country, including of fact witnesses, expert witnesses, and 30(b)(6) designees.
Before joining Sheridan Ross P.C., 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 graduated with honors from Harvard Law School, where he served as a Senior Editor of the Harvard Law Review. He also holds a master’s degree in business administration from the University of Colorado and an undergraduate degree in mechanical engineering from Brigham Young University.
