Jane Evenson

European and UK Patent Attorney | UPC Representative

Languages
  • English

Jane focuses on the biotechnology and pharmaceutical fields, with an extensive EPO opposition practice and parallel prosecution practice. Jane has almost 30 years of experience and is ranked at the top of her field by the independent guides to the legal profession. She is recommended by the IAM Patent 1000 Directory for specialist representatives at the European Patent Office (EPO) and she is recognised in the WIPR Global Leaders guide which profiles “best-in-class IP practitioners across the length and breadth of the global IP community”. Jane also is listed as a “recommended individual” in the Juve guide and is mentioned as a “key lawyer” in the CMS Tier 1 ranked team in the Legal 500 Directory.

Jane’s practice focuses on written and oral representation before the European Patent Office (EPO) in examination and opposition proceedings at first instance and at appeal. Through careful analysis, creative thinking and skilful advocacy, Jane has an excellent track record in offensive and defensive oppositions and in finding solutions for taking EP patent applications to grant where the examiner’s view has become entrenched. She has been praised for her meticulous, evidence-based, and concise approach.

Jane has particular expertise in peptide and protein-based technologies including fusion proteins and therapeutic and diagnostic antibodies and antibody conjugates, including ADCs and AOCs; cell therapies including CAR-T cells and viral vectors; antisense oligonucleotides and siRNA; diagnostic assays; PCR and amplification reactions; small molecule pharma; and biomarkers. Jane also has a strong practice in the formulations space, including pharmaceutical formulations, as well as those in the food & drink and cosmetics areas.

Jane sits on the UK CIPA life sciences committee and is Chair of the antibody sub-committee and, for many years, she was an examiner for the UK patent attorney finals level qualifying exams.
