Three major electronics companies have been sued by a foundation which claims that their use of Bluetooth wireless technology infringed on patented work at the University of Washington.

The case was filed in U.S. District Court against Matsushita Electric Industrial Co. of Japan, Samsung Electronics Co. of South Korea and Nokia Corp. of Finland by the Washington Research Institute, a nonprofit group that seeks commercial uses for patented technology developed at the state’s public universities and enforces the patents.
