  Marc Döring



Marc has over 20 years’ experience of handling IP disputes, specialising in patent litigation and co-ordinating global patent enforcement and defence cases. Marc graduated with a degree in Biotechnology before going on to study law. His patent litigation experience covers a wide range of technologies including hi-tech, mechanical engineering, chemical and medical devices, with a particular focus on pharmaceutical and biologics patent litigation including blockbuster small molecule litigation against generic companies, antibodies and immunotherapies.

Clients and peers describe Marc as “A superb all-round litigator, a master tactician who engages in the fine technical details of the case” (Chambers & Partners 2018); "We always know we have a fight on our hands when he is on the other side, and he is pragmatic - he knows which battles to fight." (Chambers & Partners 2019); a “superb litigator who combines top-level litigation nous with boundless charm” (Legal 500 2018), and “A life sciences virtuoso who relishes a bet-the-firm battle” (IAM Patent 1000, 2018).

He is recommended as a Leading Individual for IP/Patent Litigation by The Legal 500 (‘Hall of Fame’), Chambers & Partners, The International Who's Who of Patent Lawyers, The International Who's Who of Life Sciences Lawyers, MIP's Expert Guide to the World's Leading Patent Law Practitioners, MIP Stars Handbook, IAM Patent 1000 and London Super Lawyers.

Marc writes and speaks on intellectual property issues regularly. He is also a member of The Lawyers' Christian Fellowship.
