Go-to firm for life-sciences patent prosecution and opposition work in Europe. Unparalleled breadth of experience, technical background and insight. Impressive bandwidth.

Carpmaels has the legal and technical talent of a larger firm, but they seem to do a better job placing their people in a position to succeed for their clients. Moreover, the attorneys they have appear to have the right combination of effort and judgement (i.e. the wherewithal not to accept the first solution, but the self-awareness to know when to stop) which is very hard for in-house counsel to teach outside counsel.

Very strategic firm. They pay attention to what the clients’ real needs are and formulate a strategy to meet those needs.

Cameron Marshall is a formidable advocate and strategist in opposition work.

Daniel Wise is an excellent strategist and has the ability to engage in detailed aspects of a project while still maintaining perspective of the overall task. A creative problem solver.

Bruce Cockerton’s communications are always clear and informative and do not require follow-ups for clarification.
