Motorola Inc has asked the U.S. International Trade Commission to bar BlackBerry maker Research In Motion from the U.S. sale of products that it says infringe on five Motorola technology patents.

Motorola said it asked the ITC to start an investigation into RIM's use of Motorola patents, to prohibit the Canadian company from importing the infringing products and to stop it from selling infringing products that were already imported.

The U.S. based cellphone maker, which has been losing market share to RIM for years, said that the patents in question involve technology for Wi-Fi, application management, user interface and power management.

Motorola did not say which BlackBerry models infringed on its patents. A spokesperson for RIM was not immediately available for comment.
