The Effect of the Unified Patent Court (UPC) on Opposition Proceedings at the European Patent Office (EPO)The introduction of the Unified Patent Court (UPC) has brought significant changes to the European patent landscape. This article, written by Nathaniel Taylor (of Keltie's Opposition and Appeals team), takes a closer look at the impact of the UPC on opposition proceedings at the European Patent Office (EPO). The article draws on a full year's worth of opposition data - available as of 1 April 2025 - for European patents granted since the Unitary Patent system began (i.e., European patents granted between 1 June 2023 and 1 June 2024). The analysis explores overall trends, technology-specific patterns, and the strategic motives behind relative opposition rates.
