John Brunner, Partner, Attorney at C&R

John is regularly recommended by the leading IP and legal directories. He is frequently cited by Legal 500 and is recognised as an IP Star by Managing Intellectual Property (MIP). Specialising in IT and telecommunications related technology, John has been highly successful in obtaining valuable patents for a variety of software and IT businesses. This is an area where patent protection in Europe is often desirable, but can be fraught with difficulty.

Prosecution of patent applications in Europe that read onto established industry standards requires particular experience, and John has being doing this over many years for 4G (LTE), 3G, Digital Video Broadcast (DVB), and DDR (SDRAM), as well as numerous others. The specialist work involved in this field led to the creation of the firm’s ICT & Standards team, which John leads.

John has one of the largest IT and telecommunications opposition practices in Europe, and has successfully led some of the most high profile cases in this sector before the EPO’s Boards of Appeal and Opposition Divisions.

Other areas of expertise include drug delivery systems and analyte measurement devices, and in these fields, John advises a range of companies from start-ups to multinationals on more general IP issues including infringement and enforcement of patents and design rights, and licensing issues.

John is an Engineering graduate of Oxford University and a council member of the UK Group of the International Association for the Protection of Intellectual Property (AIPPI). He also sits on the Programme Committee of the AIPPI providing input on IT-related patent topics, as well as on the Intellectual Property Owners Association (IPO) Standards Setting Committee.

Prior to joining Carpmaels & Ransford and qualifying as a patent attorney, he worked for a leading technology product development consultancy in Cambridge.
