How We Live Our Values: Ambition

I am committed to helping my clients achieve their commercial goals by applying a razor-sharp focus to every aspect of their intellectual property strategy. I take pride in identifying opportunities and potential risks within patent portfolios to ensure each client is protected and positioned for growth. My goal is always to align IP with business objectives and help create real, measurable value over the long term.

In My Own Words

What I find most rewarding about my role as a patent attorney is helping clients turn innovation into meaningful commercial success. It is incredibly fulfilling to know that my work contributes directly to a company’s ability to grow, attract investment and stay competitive in its market. Whether I am drafting a patent, advising on portfolio strategy or navigating complex freedom-to-operate issues, I see the impact.

I am driven by the opportunity to support businesses at every stage. From early-stage start-ups bringing a first product to life to established companies looking to expand or acquire new technologies, I love being part of the strategic conversation. I work closely with clients to understand not only their inventions but also their broader commercial goals, and I tailor every piece of advice to help them move confidently in that direction.

For me, IP is never just about legal protection. It is a powerful business tool. Seeing clients succeed, knowing that a considered patent strategy has played a part, motivates me every day. Being able to simplify the complex, offer clarity and give clients the confidence to take their next steps is what I find most rewarding.
