Wi-Lan Inc has begun litigation against Motorola Inc , Research In Motion , and UTStarcom Inc, alleging that their mobile handheld devices and other equipment are infringing on Wi-Lan’s patents, the company said on Friday.

The Ottawa-based technology and licensing firm said it has initiated litigation in the U.S. District Court for the Eastern District of Texas, Marshall Division.

Wi-Lan also said that it has settled its dispute with Marvell Semiconductor Inc in the U.S. District Court for the Northern District of California.

Wi-Lan has licensed its intellectual property to over 100 companies and has a portfolio of patented inventions in a range of electronics and communications products, the company said.
