Myles Jelf


Myles is joint head of the patent litigation department. He specialises in intellectual property matters with an emphasis on litigation.

While his practice covers the full range of intellectual property rights it has focused in recent years upon high-tech patent litigation for multinational companies – his clients include Samsung, Google, Pratt & Whitney and ZTE. Myles is also part of Bristows’ competition department with experience of handling competition disputes before the UK courts and the European Commission. His work within this department has given him considerable experience in the interface between IPRs and anti-trust issues, particularly in the telecoms sector where he has acted in a number of leading UK cases including Samsung v Apple, IPCom v Nokia/HTC, Unwired Planet v Samsung and Conversant v ZTE. This experience has meant Myles is at the front of the developing legal area of FRAND dispute resolution.

Myles’ post-doctoral level engineering training particularly suits him to the more technically demanding cases within his patent practice. Recent cases within this practice have focused on the computing, telecoms and computer gaming sectors. Myles also, however, acts for a number of industrial clients notably in the aerospace and robotic technology sectors. Myles is a qualified Solicitor-Advocate with full rights of audience before all the UK’s civil courts. He is a member of AIPPI and President of the Board of The European Patent Lawyers Association (EPLAW), a non-profit making Association of experienced patent lawyers in the European community with the aim of promoting the equitable and efficacious handling of patent disputes across Europe.

His practice has an international nature, with the vast majority of cases in the last 10 years including the co-ordination of parallel cases in jurisdictions throughout the EU and the US. He has closely followed the development of the pan-European Unified Patent Court (UPC) throughout its gestation, attending and speaking at two of EPLAW’s Venice Patent Judges Congresses in the last five years.
