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.

Anthony was very helpful preparing our PPA. He gave me a good explanation of the process and listened to my needs. I appreciated that he had clear milestones for progress.

Anthony took the time to completely understand the scope and nuances of my invention. He used his engineering and understanding of patent law to guide my application, adding value but not overstepping. I feel fortunate to have met him, and have him on my team.
