Microsoft is seeking permission to appeal to the UK Supreme Court after losing a £270 million case brought by software reseller ValueLicensing. The Competition Appeal Tribunal ruled in 2025 that reselling Microsoft’s perpetual on-premise licences was not copyright infringement, and the Court of Appeal agreed on July 7. Judges said Microsoft’s argument echoed the 2012 UsedSoft ruling that went against Oracle. A partial stay means disclosure applications still proceed, with a hearing expected in September.
