Patent licensing company Wi-LAN Inc said it has filed a lawsuit against Research In Motion Ltd for infringing on a patent related to Bluetooth technology.

The company said it filed a suit in the U.S. District Court for the Southern District of Florida against the BlackBerry maker.

Wi-LAN, which has licensed its intellectual property to over 255 companies worldwide, alleged RIM infringed its U.S. Patent No. 6,260,168 related to Bluetooth technologies.

The company has launched a string of patent lawsuits, including one last week against Apple Inc, HTC Corp and Sierra Wireless Inc's U.S. unit over LTE mobile technology.
