Cross-border patent litigation: testing the boundaries of long-arm jurisdiction following BSH

The CJEU's BSH ruling enables EU courts to hear cross-border patent cases when defendants are domiciled in the forum state, including for non-EU patents. The UPC's Mannheim and Hamburg divisions issued injunctions covering non-UPC states in Fujifilm v Kodak and Dyson v Dreame. Munich Regional Court granted Regeneron and Bayer injunctions across 22 European countries. US entity Onesta IP sued BMW in German courts over US patent infringement, testing BSH's jurisdictional boundaries in international patent disputes.
