Germany has terminated the "Agreement between Switzerland and Germany Concerning the Reciprocal Protection of Patents, Designs and Trademarks" (13 April, 1892) as of 1 June, 2022. Articles 5 (trade marks) and 7 (patents) were still in force.
Article 5(1) concerns an exception to the territoriality principle for showing genuine use of a trade mark: use of a trade mark in the "home" state could preserve the trade mark right in the other contracting state. As a result, the relevant area for showing genuine use of a trade mark was extended. With the termination of this agreement, this rule ceases to apply.
The termination follows the ECJ's judgment in joined cases C-720/18 and C-721/18 which held that the rule was incompatible with the EU Trade Mark Directive. (In an earlier decision, the ECJ had already restricted the application of the rule where EUTMs were impacted.)
