Counsel at Osler, Hoskin & Harcourt LLP
Geoffrey Langen is based in Osler’s Ottawa office and practises IP law with a focus on pharmaceutical patent litigation, including pharmaceutical proceedings under the Patented Medicines (Notice of Compliance) Regulations. He also has experience in trademark litigation and matters related to data protection under the Food and Drug Regulations. He also regularly prepares infringement and invalidity opinions for pharmaceutical and mechanical device patents. He has appeared as counsel before the Federal Court and the Federal Court of Appeal.
Mr Langen’s practice focuses on helping clients in innovation-intensive industries, including the pharmaceutical, life sciences and biotechnology sectors. He assists clients in bringing new products and services to market, or in preserving their market position, by strategically obtaining or litigating IP rights. In addition to his legal training, Mr Langen has a BSc in biochemistry and a MSc in molecular biology. His graduate work in molecular biology, microbiology and genetics has been published in several peer-reviewed journals.
Mr Langen was a member of the Osler team that represented the successful appellant in Yves Choueifaty v Attorney General of Canada, 2020. This decision provides important insight into how the Canadian Intellectual Property Office will determine patentable subject-matter for computer-implemented inventions.
Before joining the firm, Mr Langen practised at a boutique firm that specialises in IP law. He has been recognised as a Rising Star by Managing Intellectual Property magazine.
