German patent firm IPCom wants to ban the sale and distribution of HTC 3G devices in Germany as quickly as possible.
IPCom made the comments shortly after a court ruling against the Taiwanese firm.
"IPCom now intends to execute this injunction in the shortest possible time," the company said.
"We will use the right awarded by the courts, likely resulting in HTC devices disappearing from shops during the crucial Christmas season."
IPCom has battled for years against HTC and Nokia in European courts.
IPCom had acquired Bosch's mobile telephony patent portfolio, created between the mid-1980s and 2000, which includes about 160 patent families worldwide including some of the key patents in the wireless industry, including a patent which standardizes a mobile phone's first connection to a network.
