Motorola is going after Research In Motion (RIM) with a patent complaint filed Friday with the U.S. International Trade Commission (ITC). Motorola alleges that the BlackBerry maker is violating five of its patents related to Wi-Fi access, application management, user interface and power management.

“In light of RIM’s continued unlicensed use of Motorola’s patents, RIM’s use of delay tactics in our current patent litigation, and RIM’s refusal to design out Motorola’s proprietary technology, Motorola had no choice but to file a complaint with the ITC to halt RIM’s continued infringement,” said Motorola Senior Vice President of Intellectual Property Law Jonathan Meyer in a statement. “Motorola will continue to take all necessary steps to protect its R&D and intellectual property, which are critical to the Company’s business.”

Motorola is asking the ITC to bar the importation and sale of BlackBerry devices that it claims infringe on its patents.

RIM could not be reached for comment by press time. The ITC complaint is part of a long-running legal battle between the two companies.
