Attached: Case No. UPC_CFI_0001734/2025
Malikie is an intellectual property management company headquartered in Ireland, primarily engaged in the management and licensing of patents related to communication technologies. Its patent portfolio mainly originates from historical asset transfers by major technology companies, including core patents accumulated by BlackBerry in the fields of communication and mobile technology.
Unlike traditional device manufacturers, Malikie does not directly produce or sell end products. Instead, it monetizes its technology through patent licensing and litigation, leading to its classification as a Non-Practicing Entity (NPE). In recent years, the company has progressively intensified its patent enforcement activities in European and North American markets, particularly targeting key technology areas such as 4G, 5G, and emergency communications.
The patent in question is European Patent EP 3797535, originally held by BlackBerry and later transferred to Malikie. This patent pertains to 5G technology related to emergency communication services. Malikie alleges that Xiaomi implemented this patented technology in its smartphones without authorization, constituting infringement. Consequently, Malikie has petitioned the UPC to order Xiaomi to cease infringement and bear corresponding legal liability.
