Camilla Balleny


Camilla is a Partner in the Dispute Resolution team. She has focussed on multi-jurisdictional patent litigation and advisory work for all of her career.  Camilla now works exclusively on matters relating to the life sciences industry and is recognised for her expertise in this arena. She has a degree in genetics and having spent time in-house at a large biotech company, Camilla has a developed a very strong understanding of both the technical and commercial world in which her clients operate.

As one of the firm’s founding litigation partners and with nearly 20 years of experience, Camilla provides “outstanding litigation advice” (Managing IP). According to Legal 500 2022, Camilla “does an excellent job of overseeing a large team responsible for running a large contentious pharmaceutical patent litigation/enforcement program on a pan-EU basis.” During the near 5 years that she has now worked at Carpmaels & Ransford, alongside the noted expertise of our patent attorney team, Camilla is often asked to advise on litigation planning and has a wide range of clients for whom she regularly consults on matters relating to UK litigation and associated advice.   She has also developed particular expertise for the strategic management of patent litigation which spans multiple jurisdictions and covers multiple patents.

In addition to her expertise in patent litigation, Camilla has a strong understanding of the overlapping protections of patents and regulatory exclusivities and also supplementary protection certificates (SPCs).

Her work is most recently exemplified by Camilla’s representation of clients in the UK High Court, Court of Appeal and at the Court of Justice of the European Union.  Recent examples of cases include Cubist-v-Hospira  [2018] EWCA Civ 12,  Actavis-v-Sanofi [2014] R.P.C. 20 but her career started with her involvement in cases such as Taylor-v-Ishida [2001] EWCA Civ 1092 and Haberman-v-Jackel [1999] 1 WLUK 492.

"Camilla is very thoughtful, strategic, and doesn't leave any stone unturned. She is proactive in identifying potential issues and presents them in a way that allows clients to make an informed decision."
