Kathleen is highly experienced in multi-jurisdictional patent litigation having acted in some of the most high-profile patent disputes of the last 20 years.

She is cited as a leading UK patent litigator by the major legal directories. Kathleen is well placed to advise clients on the new Unified Patent Court (UPC) - see further details at EIP Amar, our alliance created to support clients in any litigation before the UPC.
Kathleen has advised clients across a variety of industry sectors, substantially in the telecoms, electronics, IT, pharma/biotech, engineering and chemical industries. This includes multi-jurisdictional litigation co-ordination, interim injunctions, infringement and validity litigation in the High Court, Court of Appeal and Supreme Court.

This includes advising on responses to requests for information from the European Commission, “dawn raids” and advising on the consequences of the Commission’s findings in the inquiry.
