Recently, the Mannheim Regional Division of the UPC issued a ruling approving the joint motion filed by the Irish patent operating company Malikie Innovations and Xiaomi to dismiss the lawsuit regarding European Patent No. EP2387862.

The case began in November 2025, when Malikie filed a complaint with the Mannheim Division alleging that Xiaomi had infringed its EP2387862 patent, which relates to “systems and methods for determining the cause of an event.” Xiaomi promptly responded with a counterclaim seeking invalidation. Both parties jointly filed a motion to dismiss the case before the court had entered into substantive proceedings, and did not request a ruling on the allocation of litigation costs.

On August 24, 2026, Tobias Sender, Judge and Rapporteur at the Mannheim Regional Division of the UPC, signed an order granting Malikie’s motion to dismiss the infringement claim and accepting Xiaomi’s motion to dismiss the counterclaim for revocation filed against the patent. In accordance with the rules governing early withdrawal of claims, the court ruled that each party would be refunded half of the litigation fees already paid in advance—Malikie received 15,500 euros (approximately 120,845.75 RMB), and Xiaomi received 13,250 euros (approximately 103,311.58 RMB).

In addition to the Mannheim case, the parties have other pending litigation before the UPC Munich Division, as well as in courts in India and Germany. Notably, Malikie filed another infringement lawsuit against Xiaomi at the Munich Regional Court I based on Patent EP2879321; however, the German Federal Patent Court has already issued an informal assessment regarding this patent, preliminarily determining that it faces the risk of being declared invalid due to lack of novelty.
