Research Institute Sues Phone Makers Over Bluetooth
Jan 3, 2007, 1:57 PM by (staff)
The Washington Research Foundation is suing Nokia, Panasonic and Samsung for patent violations. The foundation represents researchers from universities in Washington State, one of whom filed a patent on high-frequency broadband tuning methods in 1999. The researcher and the foundation believe this method is used in Bluetooth. However the Bluetooth spec was developed in the mid-1990s and solidified in 1998, before the patent was filed. Despite a possible prior art defense, American chip maker Broadcom has licensed the technology from the Washington Research Foundation. Chipmaker CSR, whose Bluetooth chips are in Nokia, Panasonic and Samsung devices has not licensed the patent.
