Motorola may have had some bad news today, but they were noticeably absent from a line up of consumer electronics manufactures that are being sued by the Washington Research Foundation (WRF) for using Bluetooth technology, which WRF claims is an infringement on their patents.

The suit alleges that the companies Nokia, Samsung and Panasonic (part of Matsushita) used technology from CSR Plc out of the United Kingdom that infringed on the 3 of 4 patents that WRF holds on the technology.

Shares of CSR fell after the announcement of the lawsuit.  It would appear that the larger conglomerates might be at least the victim of not performing enough due diligence into the IP rights of one of their outsourced vendor partners.
