Mark Kramer
Mark is an experienced intellectual property (IP) lawyer advising on both contentious and non-contentious matters across the full range of IP rights. He joined Potter Clarkson in 2021 to lead the firm’s London solicitor team. His clients range from multinationals to start-ups and individuals, all of whom value his clear, commercially focused advice.
Mark supports clients across sectors as varied as financial services, automotive, green-tech, creative industries, FMCG and aviation, helping them protect, commercialise and enforce their IP.
He has significant non-contentious experience, working closely with clients and often in collaboration with the firm’s leading patent and trade mark attorneys. His work ensures that the contractual framework around a client’s IP supports their commercial and developmental goals. He also plays a key role in Potter Clarkson’s IP due diligence offering, supporting investors, acquirers and target companies.
Mark’s contentious experience spans the full range of IP rights. He has represented clients before the Court of Appeal, the High Court and the Intellectual Property Enterprise Court (IPEC). Much of his contentious work has an international focus, and he has considerable experience in leading and coordinating international disputes.

How We Live Our Values: Ambition
I’m driven to secure the best possible outcome in every situation, always with my client’s goals in mind.
In My Own Words
The day-to-day problem solving brings me back to the office every day, but the most rewarding part of my role is supporting early-stage businesses with the wit, the drive and the ideas to change the world.
Many of our clients at Potter Clarkson are rising to meet the health or environmental challenges that may, or indeed will, affect us all. It’s a pleasure to support them on that journey, and I hope that our advice has improved their odds of success.
