A legal claim has been brought against Microsoft over alleged licensing practices that could result in a multibillion-pound payout for UK customers. Following publication of this article, a Microsoft spokesperson told us: "This new collective action is based on the same unsubstantiated claims regarding second-hand software licensing that have been litigated for several years in another case [ValueLicensing's claim against Microsoft]. Microsoft believes these claims are meritless and will vigorously defend against them."

Robert O’Donoghue KC, counsel to Microsoft, told the CAT in a case management conference today that it does not have jurisdiction to evaluate a key issue in ValueLicensing’s abuse of dominance claim against the tech company, as it does not fall within the specialist court’s remit.

Microsoft, sued by ValueLicensing, told a judge today that the UK competition court doesn’t have jurisdiction to deal with narrowed-matters over the lawsuit because they concern copyright law.

This is the Defendant’s Response to the Claimant’s Request for Further Information dated 31 January 2025 (the “RFI of 31 January 2025”).

Microsoft must respond to ValueLicensing’s RFI by 2nd May 2025.
