Isobel Barry

Partner

Isobel advises innovator pharmaceutical companies through all stages of the pharmaceutical product lifecycle. Much of her time is spent on contentious matters relating to exclusivity-driving patents protecting commercially important products, including patents for small molecules, combination therapies and pharmaceutical formulations. She defends such patents in multiparty opposition and appeal procedures at the European Patent Office, and provides crucial support for pan-European enforcement and the defence of nullity actions.

Isobel applies the perspective gained from her extensive contentious work to drafting and prosecuting patent applications at the European Patent Office, including those for new chemical entities, drug delivery systems, dosage regimens and manufacturing methods in the pharmaceutical field. She also coordinates the prosecution of global patent portfolios for her clients. She acts for some of the largest pharmaceutical companies in the world, including Novartis, Janssen Pharmaceuticals, Gilead Sciences and Vertex Pharmaceuticals, as well as smaller companies and university spin-outs. Isobel was named as a Rising Star in IP by Managing IP in 2018, 2019 and 2020 and in the patent category of the 2021 Legal Media Group Expert Guide. In 2020, she was named as one of World IP Review’s influential women in IP, featuring in a list of 20 global trailblazers.

Isobel holds a first class degree from the University of Cambridge, where she was awarded the GlaxoSmithKline Prize for the Best Organic Chemistry Research Project in her final year.

Isobel is passionate about diversity and inclusion and has been active in IP Inclusive, an initiative to improve diversity and inclusion in the IP professions in the UK, since its early days. She sits on two subcommittees of IP Inclusive, running events for the support and networking groups IP Out and Women in IP.

Isobel Barry’s “attention to detail is absolutely remarkable and this is reflected in the quality of her drafting”.
