Gregory Bacon


Greg’s extensive scientific background gives him a valuable understanding of technical issues that can underlie IP matters, particularly in the life sciences field. He has advised and represented clients on small molecule pharmaceuticals, biologics (originators and biosimilars), medical devices (hardware and software), as well as in the cosmetics, chemicals, technology, shipping and online publishing sectors.

Greg has represented clients in many cases before both the English High Court (including Patents Court) and Court of Appeal. In addition, Greg has extensive experience of strategic multinational litigation in multiple jurisdictions, including at the EPO, through global pharmaceutical product coordination projects for many clients.

He has also spent time on secondment to the IP litigation department of a leading IP law firm in the Netherlands as well as the UK legal department of a global healthcare IT company, working on non-contentious IP/IT, regulatory and commercial matters.

Greg is a regular contributor to the monthly EPO reports which Bristows produce for the CIPA Journal and writes on UK cases for a number of IP blogs. He is also the editor of our On the Pulse life sciences microsite and one of the editors of our Biotech Review publication which explores key issues and developments in the biotech space, and co-authored the UK chapter of the AIPLA’s International Patent Litigation guide.
