Myles practice has focused in recent years upon high-tech disputes for multinational companies and his clients include Samsung, Google, Panasonic and Collins Aerospace.

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, Conversant v ZTE and Panasonic v Xiaomi. 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 and telecoms sectors. Myles also, however, acts for clients in the aerospace and robotic technology sectors.

Myles also works closely with Bristows’ Commercial Disputes team in relation to commercial disputes relating to the operation of complex technologies.

Myles is a qualified Solicitor-Advocate with rights of audience before all the UK’s civil courts and is a qualified Irish Solicitor with full rights to practice before the Irish courts.

Myles is also a registered representative with rights to practice before the European Unified Patent Court and is presently running a patent dispute before the Hague local division of the UPC.

Some of Myles’ work highlights include:

  • Winnow Solutions v Orbisk – patent infringement before Hague local division of UPC relating to food waste management technologies.
  • Panasonic v Xiaomi and Oppo – patent infringement and FRAND rate determination in relation to 4G cellular technology.
  • Orderly Mind Ltd v Queue-it SA – patent infringement relating to online queuing systems.
  • Unwired Planet v Samsung & Google – patent infringement and FRAND defences in relation to 3G and 4G cellular technology.
  • Conversant v ZTE – patent infringement and FRAND defences in relation to 3G and 4G cellular technology.
  • IPCom v RIM / Nokia / HTC / Xiaomi / Vodafone – a number of disputes before the UK Courts concerning patent infringement and FRAND defences in relation to 3G and 4G cellular technology.

  • Texas Instruments v Hyundai – patent dispute concerning computer memory lithographic processes.

His practice is international nature, with the vast majority of cases in the last 25 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, regularly attending and speaking at the EPO and EPLAW organised Venice Patent Judges Congress.
