## Overview The UK High Court saw a significant increase in newly filed patent cases in the past year, rising from 44 to 58 cases, reversing a multi-year decline that hit an all-time low in 2022 (JUVE Patent, citing UK civil justice statistics). ## Key Facts - UK patent litigation volume had been steadily decreasing since the launch of the Unified Patent Court (UPC), reaching a record low in 2022 (JUVE Patent). - Last year's rebound to 58 cases suggests litigants may be recalibrating strategy around where to file, amid growing friction between UK courts and the UPC (JUVE Patent). - The increase is described as coinciding with intensifying tensions between the UK High Court system and the UPC, though specific causes are not detailed in initial reporting. ## Why It Matters For patent litigators and IP strategists, the choice between UK national courts and the UPC has major implications for venue strategy, remedies (including pan-European injunctions), and forum shopping. A resurgence in UK filings could signal growing distrust of UPC procedures, jurisdictional uncertainty, or strategic hedging by litigants seeking to preserve non-UPC options post-Brexit. This trend will likely continue to develop as more data and case studies emerge on comparative advantages of each forum. ## Related Developments Relevant to the broader European patent enforcement landscape, including UPC Court of Appeal jurisprudence, Nokia's FRAND campaign and UPC litigation withdrawals, and new market entrants like Pairs Law and Perkins Coie's London expansion.
