Craig has considerable experience in providing pragmatic, commercially focused advice to a wide-range of clients and in relation to biotechnological, pharmaceutical, chemical and medtech inventions. As well as patent drafting and prosecution, Craig advises on the development of company-wide IP strategies, preparing for or carrying out funding/acquisition due diligence, and advising on aggressive/defensive strategies in relation to third party IP.

In the biotechnology and pharmaceutical sectors, Craig has advised on therapeutic inventions (including small molecule, protein and microbial based therapeutics), diagnostic inventions (eg involving biomarkers such as nucleic acid polymorphisms, cytokines and ECG output), and industrial microbial inventions. He has a particular interest in inventions relating to bacteriophage.  In the chemical sector, Craig has advised on material chemistry, food technologies and pharmaceutical-formulation technologies. He also has experience in the field of medtech (e.g. cardiovascular implantable devices, microfluidic devices and catheters) and packaging. Having worked closely with multi-national corporations, Craig is aware of the particular challenges associated with efficiently prosecuting large multi-national patent portfolios, whilst keeping them relevant to the business. He values this experience as it has helped him to provide expert guidance to SMEs as they grow or prepare for acquisition, and to academic institutions as they seek commercial collaborators.

He has a proven track record of providing successful outcomes for clients in a range of legal proceedings, including opposition proceedings, entitlement proceedings, and in-person USPTO examiner interviews.  He has co-written an amicus curiae that was filed with the US Supreme Court in connection with Sequenom v Ariosa, and has assisted many clients to successfully obtain investment, including listing on AIM.


Craig has a BSc in Physiology and Pharmacology from the University of Dundee, and an MSc in Intellectual Property from the University of London. Prior to qualifying in London as a patent Attorney, he was a Patent Examiner at the UKIPO.


Craig became a partner of HGF in April 2017 and now lives and practices in both the UK and in Ireland, being a qualified European, UK and Irish Patent Attorney.
