Position
William is an intellectual property lawyer with a particular focus on complex patent litigation and strategy in the telecommunications, electronics and life sciences areas.
He advises on patents in a broad range of technologies, but has recent experience with complex patent cases in the high-tech mechanical engineering, automotive, and telecoms (including mobile phones, internet, web and WiFi technologies) sectors. He has advised on some of the most complex patent cases in the UK courts, relating to software, biotechnology and vaccines and involving diverse legal issues, including entitlement and questions of ownership following an IP holder’s insolvency. He has significant experience in media and telecommunications matters involving competition, FRAND and SEP issues.
The majority of William’s cases are before the UK High Court but involve harmonisation with parallel proceedings in Europe (including in the EPO), the US and Asia. He has also acted for clients in confidential arbitrations and mediations. His commercial work involves advising clients in a diverse range of industries, including motor racing and interior design.
In 2020, William was named a Rising Star in the MIP IP Stars listings.
