My experience spans a broad range of IP rights including patents and SPCs, trade marks, copyright, database rights and domain names.

I have a particular interest in litigation in the life sciences field and have experience of patent and SPC proceedings before the UK Intellectual Property Office, Patents Court, Court of Appeal and Court of Justice of the European Union, including acting as lead assistant in Sandoz Ltd & Anor v G.D. Searle LLC & Anor and Master Data Center, Inc. v The Comptroller General of Patents.

I also advise clients on the management of their global trade mark portfolios and the enforcement of their soft IP rights, and have acted in various high profile soft IP disputes including Karen Millen v Karen Millen Fashions Ltd & Anor (trade marks) and 77m Ltd v Ordnance Survey Ltd (copyright and database rights).

Prior to joining Fieldfisher, I studied chemistry at Imperial College London and spent two years working at a top-ranked patent litigation firm.  This background has come in helpful in cases with technical elements, for example those involving pharmaceuticals and Markush formulae.  In 2017 I obtained a Postgraduate Diploma in Intellectual Property Law and Practice from the University of Oxford.

I am listed as a “Rising Star” in the 2021 edition of the Legal 500, in which I am described as follows: “Chris Leung is outstanding; a star of the future. Fantastic grasp of issues, good attention to detail, really thinks about the case and understands the interplay between argument and strategy.”
