Academic and Research Background

After his PhD, John moved to the Dyson Perrins Laboratory at the University of Oxford, UK where he undertook post-doctoral research in the group of Professor Sir Jack Baldwin FRS. He moved on to work at Cytocell Ltd as a research scientist where he developed isothermal nucleic acid amplification technologies.

Professional Experience

John joined the patent profession in 2000. He began his career at D Young & Co. where he trained and qualified as a Patent Attorney. He was a Partner in an international law firm and another firm of patent attorneys before joining Script IP.

John's clients have included universities, early stage companies and SMEs, as well as very well-known biotechnology, healthcare and medical device companies. He therefore has experience of the differing requirements of clients which adds an interesting layer of diversity to his practice.

His skills also extend to opposition and appeal proceedings and oral proceedings before the European Patent Office. He has recently enjoyed a successful spell in EPO opposition proceedings defending three different patents and maintaining all of them as granted. He also provides patentability, non-infringement and freedom to operate opinions for his clients.
