With the introduction of the Unified Patent Court (UPC) and the new European Patent with Unitary Effect, the European patent litigation system is undergoing a set of fundamental reforms. This timely book assesses the current state of European patent litigation by analysing recently published data on Europe's four major patent jurisdictions - the UK, Germany, France and the Netherlands - and also looks ahead to examine what the impact of the UPC is likely to be on Europe's patent litigation system in the near future.
