David S. D’Ascenzo
Intellectual Property Attorney
David has been an intellectual property attorney since 1996 and feels privileged to work with the variety and caliber of clients who entrust him with their intellectual property needs. David respects the fact that the intellectual property arena is a complicated, expensive, and risky area and that clients often have only one opportunity to secure the proper protection and advice. He enjoys being an intellectual property attorney and believes that this sincere enthusiasm is reflected in his work and the many years that he has been fortunate to work with his current clients.
David’s intellectual property practice is about as varied as they come. His clients range from individual inventors and start-up companies to established, multinational corporations. He advises clients on the full spectrum of intellectual property law, from initial evaluations of inventions and potential trademarks, to worldwide licensing, defense, and enforcement of his client’s intellectual property rights. David’s practice includes substantial trademark and international components, as well as patent prosecution in such varied fields as fuel cells, sporting goods, petrochemical and gas generation, processing, and purification, tools, toys, firearms, and household chemical and electrical products. David has successfully prosecuted hundreds of patents and trademarks in the U.S. and foreign countries, and has litigated and otherwise enforced his clients’ rights on multiple occasions. He is an experienced negotiator and frequently counsels clients on such diverse topics as freedom to operate opinions, strategic acquisitions, licensing, international intellectual property, Customs and international treaties, and trademark and patent development strategies.

He is a former U.S.S.F. referee, has coached adult and youth teams, and currently enjoys coaching his children’s teams.
