How We Live Our Values: Ambition
I'm driven by curiosity, whether it’s exploring emerging technologies, evolving IP case law, or the strategic goals behind a client’s innovation. I don’t just want to understand how something works, but why it matters commercially. That way, I can help support an IP strategy that aligns with the client’s goals and delivers real value.
In My Own Words
The most rewarding part of my role is seeing the tangible impact that a well-structured IP strategy can have on a client’s success. Whether it is securing a patent that supports a product launch or winning an opposition that protects a client’s market position, I take pride in helping turn innovation into commercial reality. I also value mentoring the next generation of patent attorneys, sharing knowledge, building confidence, and supporting their growth into trusted advisors.
