Career

William is a specialist patent barrister with key expertise in handling patent litigation in both the life sciences and telecommunications sectors, with particular specialism in biotechnology and FRAND disputes.

William has broad experience of biotechnological patent disputes from small molecules (e.g. Gilead v Idenix, Gilead v Nucana, Accord v RCT, Aspire v Alcon) to proteins/antibodies (e.g. Regeneron and Bayer v Amgen and others, Eli Lilly v Genentech, Takeda v Hoffman La Roche). William’s biochemistry background has provided a strong footing for this practice in biotechnological patents, where he has particular experience of litigating technically complex major patent disputes often with multi-jurisdictional issues.

He has also been involved in a significant number the major FRAND disputes which have occurred in the UK Courts including Philips v ASUS, Philips v TCL, Mitsubishi and Sisvel v Oneplus and others, Lenovo v Interdigital (both in the High Court and on appeal), Philips v OPPO and Panasonic v OPPO.
