Professional background

Professional background

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

I have a particular interest in litigation in the AI, technology and life sciences fields, and have represented clients in proceedings before the Intellectual Property Enterprise Court, High Court (including the Patents Court), Court of Appeal, Supreme Court and Court of Justice of the European Union.

I have been involved in various high-profile soft IP cases across a range of sectors, including Getty Images v Stability AI (generative AI models), SkyKick v Sky (software), Genius Sports v Soft Construct (sports betting data), 77m v Ordnance Survey (mapping) and Karen Millen v Karen Millen Fashions (fashion).  I have also been involved in patent and SPC cases including ICON v Peloton (software for sports equipment), Master Data Center v The Comptroller General of Patents (pharmaceuticals) and Sandoz v G.D. Searle (pharmaceuticals).  I also advise clients on UK Intellectual Property Office actions and the management of their global trade mark portfolios.

Prior to becoming a lawyer, I studied chemistry at Imperial College London.  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" for patents, and a "key lawyer" for trade marks, copyright and designs, in the 2024 edition of the Legal 500, and have been described as follows:

Chris Leung is a very capable associate with real technical acumen.” (The Legal 500 UK 2024, Intellectual Property: Trade Marks, Copyright and Designs)

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.” (The Legal 500 UK 2021, Intellectual Property: Patents)
