Context: Siemens filed two patent infringement actions against Honor before the Munich I Regional Court on 26 September 2025, asserting EP2070269 (“Packet scheduling”) and EP2052517 (“Procedure and system for providing an access-specific key”). Honor subsequently challenged both patents before the German Federal Patent Court, filing parallel nullity actions on 14 January 2026 (EP’269) and 20 January 2026 (EP’517).
What’s new: The Munich I Regional Court has stayed Siemens’ infringement action concerning EP’517 following a 16 July, 2026 hearing, even though the German Federal Patent Court has not yet issued its preliminary opinion in the parallel nullity proceedings. In the related EP’269 case, the court postponed the hearing until December after Siemens filed additional auxiliary requests in the validity challenge.
Direct impact: The stay pauses Siemens’ effort to enforce one of the asserted standard-essential patents (SEPs) against Honor while the parallel validity challenge continues before the German Federal Patent Court, potentially delaying any infringement ruling on that patent.
Wider ramifications: Although a single procedural ruling does not signal a broader shift, the decision adds to the discussion over how readily the Munich I Regional Court will stay SEP infringement proceedings while parallel validity challenges are pending. Whether similar decisions emerge in future cases will likely shape practitioners’ expectations of the court’s approach.
