About James

James joined HLK in the Chemistry and life sciences team as a Trainee Patent Administrator 2019 in the firm’s Bristol office, and became a qualified Patent Administrator after passing the CIPA Introductory Certificate in Patent Administration. James left HLK in March 2023 and spent nearly 3 years at another IP firm as a Patent Paralegal and then Senior Paralegal.

While he was away, James completed the European Certification in Patent Administration in 2025, before returning to HLK in February 2026 as a Senior Patent Administrator, back in the Chemistry and life sciences team but this time in the firm’s London Office.

James has managed extremely varied caseloads across his time at HLK and elsewhere and has therefore built up extensive knowledge of the administrative aspects of all patent law. He has a wealth of experience in all levels of patent formalities, from pre-filing actions, to filing, prosecution and post-grant procedures. Alongside European and United Kingdom applications, James has managed large worldwide portfolios, building up knowledge and experience of Patent formalities in an extensive number of countries. James also has significant experience of managing the formalities for EPO Oppositions and Appeals, in particular at his previous firm where this type of work took up a substantial part of his portfolio.

James has a particular interest in procedural change practices and enjoys training new colleagues. James finds working with a wide range of clients, adapting to their unique needs and building relationships to be the most rewarding part of his job.
