Gregor Grant

Gregor is an experienced hands-on patent litigator and Of Counsel at Marks & Clerk Law. 

“Gregor Grant is called upon for his expertise in patent litigation. He has achieved successful outcomes for clients in cases concerned with life sciences, hi-tech and mechanical engineering technologies.”
(Chambers & Partners)

With over 50 years’ experience in intellectual property law, Gregor is a “renowned litigator” (IAM Patent 1000) and has been “one of the leading lights in patent litigation for many years" (Chambers & Partners). He adds a wealth of knowledge and invaluable expertise to the firm’s patent litigation team, playing an active role in advising clients across all sectors.

His interest in patents stems from tinkering with bicycles and motorcycle engines. An early interest in all things mechanical branched out into life sciences and all fields of technologies, and other IP rights including copyright and designs.

Gregor has handled cases that include those in the fields of clinical diagnostics, stents and implants, pharmaceuticals and therapeutic antibodies, hydraulic lifting machines, high pressure valves, machine tools, food technology, food packaging, computer systems and electric motors. Many of these have had a multi-jurisdictional aspect.

Pursuing a career in IP rescued Gregor from an alternative career as an impoverished blues pianist. The music has not been forgotten...He plays keyboard in Marks & Clerk Law’s rock band "The Defendants”.
