Industry focus
At the heart of my patent law practice is a commitment to client-first advocacy. I believe that every invention is more than a technical achievement—it’s a reflection of human ingenuity and ambition. My role is to translate that vision into robust legal protection, guiding clients with clarity, strategy, and unwavering dedication to their goals.
How I represent clients at Schwabe
I am a scientist-turned patent attorney with in-house experience. I understand both the challenges inventors face in bringing their ideas to life and the importance of aligning IP strategy with business objectives. I help clients navigate the complex world of patent prosecution, ensuring their inventions in life biotechnology, medical devices, and chemistry are protected and positioned for success. With 10 years of experience before the USPTO, I’ve developed a deep understanding of the patent preparation, filing, and prosecution process, as well as patentability searches, invalidity opinions, and portfolio management. In a few short years, I’ve successfully secured approximately 120 patents worldwide, including 70 in the United States, for an industry client.
With extensive hands-on research experience in life sciences, biotechnology, and bioengineering, paired with over a decade in patent law, I bring a practical and solutions-driven approach to every project. From drafting applications to managing portfolios and addressing nuanced legal challenges, I’m committed to helping clients turn groundbreaking ideas into secured assets that drive their businesses forward.
