Gemma is a contentious intellectual property specialist with a focus on patent litigation in the life sciences sector (pharmaceuticals, biotech and chemical processes). Her background in biochemistry provides her with a sound understanding of the technical aspects of such disputes.

Gemma has experience of litigating patents for successful pharmaceutical products before the English Courts, including experience of obtaining preliminary injunctions. She has worked in teams to develop successful strategies, often combining patent and regulatory law, to assist pharmaceutical companies in the enforcement of their rights.  She has also handled patent cases for other sectors, including consumer goods, and acted in disputes relating to other intellectual property rights, such as trade marks.

Gemma has extensive experience of cross-border litigation within Europe and elsewhere in the world, including India.  This involves working closely with other lawyers, in-house counsel and patent attorneys to ensure consistent and optimal arguments are deployed in all jurisdictions regarding the defence and enforcement of portfolios of patents.  This has involved amongst other things preparation for and attending preliminary injunction and main action proceedings in a number of countries around the world.

Gemma has spent time on secondment to the UK department of a leading global pharmaceutical company.  She has also presented on a number of topics and is a regular contributor to the monthly EPO reports which Bristows produce for the CIPA Journal.
