Turhan Sarwar is an experienced intellectual property attorney with a practice encompassing litigation and post-grant proceedings at the trial and appellate levels, IP portfolio development and licensing, and counseling regarding the prosecution of domestic and international patent and trademark applications.

Turhan has extensive experience with litigation strategy and procedure in federal and state courts, proceedings before the Patent Trial and Appeal Board (PTAB), and investigations before the US International Trade Commission (ITC). His litigation skillset covers cases from start to finish—including complaint and answer drafting, managing discovery, taking and defending depositions, working with expert witnesses to develop technical arguments, managing parallel PTO proceedings such as inter partes review (IPR), claim construction and summary judgment strategy, drafting and arguing motions, trial witness preparation, settlement negotiations, drafting licensing agreements, and appellate briefing.

Clients regularly turn to Turhan for advice related to patent prosecution, including analyzing office actions and applicant responses, drafting claims, and identifying areas for IP development within portfolios to align existing patent families with market shifts and evolving business strategies. He also oversees development of trademark portfolios for small businesses and start-ups, including through registrations, supplemental registrations, and oppositions.

Prior to practicing law, Turhan was a consultant at a biometrics consulting and integration firm conducting technology research for individual biometric modalities (fingerprint, iris, etc.), industry research for identity management and security applications, and feasibility and vulnerability analysis of specific biometric deployments for government and commercial clients.
