A registered patent attorney, I followed my decade of engineering experience at a Fortune 100 company with more than 25 years of legal practice in law firms, a major scientific research institution and public corporations, most recently as worldwide director of intellectual property for Microsoft Services.
In my practice now, while I serve clients of all sizes, my focus is particularly on the needs of the individual inventor and entrepreneurial start-up. My goal for each client is to craft cost-effective strategies for developing, strengthening and enforcing the client's valuable intellectual property portfolio.

Rock Star IP attorney
Anthony Claiborne goes above and beyond the call of duty. He not only provides prudent and practical advice, but a calm and compassion that pulled me down from the ceiling during a very angst ridden IP contract negotiation.
