Mark Lezama is a litigation partner in our Orange County office focusing on patent and technology-related disputes.
Mark represents patent owners and accused infringers alike, in jurisdictions all across the country. He approaches litigation thoughtfully, working with clients to position their cases for meaningful victories. In a contract case involving a patent license, Mark obtained for his client a court-ordered injunction requiring the licensee to honor its agreement and withdraw its challenges to his client’s patents at the Patent and Trademark Office. When the licensee appealed, Mark obtained an affirmance from the Ninth Circuit for his client. In another case, Mark obtained key evidentiary rulings for his client early on, laying the groundwork for the court to rule that his client did not infringe just six months into the case. Mark builds on courtroom successes like these by planning and taking strategic steps out of court for his clients, including pursuing inter partes review by the Patent Trial and Appeal Board. He also counsels on patent-portfolio strategy, patent-infringement and validity assessments, and licensing transactions.
Owing to his strong background in mathematics and computer science, Mark’s practice encompasses a wide variety of technologies, including such diverse fields as quantum computing, mobile apps, computer networks, cryptography, optics, medical devices, thermoelectrics, internal-combustion engines, and surf systems for sport boats.
Mark is currently serving as a lawyer representative to the Ninth Circuit Judicial Conference and as a member of the Local Rules Advisory Committee for the Central District of California. Mark’s connection to the Central District dates back to his first summer as a law student, when he externed for the Honorable Rosalyn M. Chapman.
Mark chairs the firm’s Diversity Committee and is a past President and board member of the Orange County Coalition for Diversity in the Law. He has also served as a mentor with the Foundation for Advancement of Diversity in IP Law.
