Daedalus Prime LLC v.Xiaomi Inc., Xiaomi Communications Co., Ltd., Xiaomi Technology Netherlands B.V., Xiaomi Technology Germany GmbH, MediaTek Inc.
Luxembourg (LU) · UPC-001344
Daedalus Prime LLC brought a patent infringement action before the Hamburg Local Division of the Unified Patent Court against five defendants, including Chinese and Taiwanese entities, seeking to serve the Statement of claim on the Chinese Xiaomi companies via Xiaomi Germany and on MediaTek (Taiwan) via MediaTek Germany GmbH under Rule 271.5(a) RoP. The Local Division dismissed the request, holding that service must follow Rules 273 and 274 RoP. On appeal, the Court of Appeal rejected Daedalus's appeal, confirming that group companies in Contracting Member States cannot automatically be treated as statutory seats, central administrations, or principal places of business of defendants domiciled in China or Taiwan, and that Hague Convention methods (for China) and diplomatic/consular channels (for Taiwan) must first be attempted.
