IP litigation boutique Powell Gilbert LLP has quickly established itself as a major success story, winning some significant new clients - including US-based Dartmouth College - since its formation by a group of ex- Bristows partners. Strongest on life sciences and technology sector patent litigation, it represented Yeda - the Israeli Weizmann Institute of Science’s technology transfer arm - in a patent entitlement dispute brought against Sanofi-aventis and ImClone, resulting in a House of Lords decision in Yeda’s favour and a subsequent settlement. Clients of Tim Powell, who led this work, praise his ‘excellent’ response times and availability, and his ‘profound’ knowledge of the industry', as well as the firm’s ‘highly skilful’ associates and ‘very good achievements for reasonable prices’. Simon Ayrton leads the soft IP practice, clients confirming that ‘his experience in IPR matters is' very satisfying’. Alex Wilson wins praise for the cultural understanding that enables him to successfully coordinate litigation throughout Europe.
