Patent Calls Investigation Concludes 19 Tech Companies Including Dell and Intel Are Not Infringing Wi-LAN ?Bluetooth? Patent

By Philip Brooks

ADVERTISEMENTS

The following is excerpted from an April 14, 2010 Business Wire item published at EDA Cafe:

Patent Calls, Inc., an independent research firm that provides unbiased, comprehensive patent reports and analysis, has conducted an independent analyst report on US Patent 5,515,369 (?369) ? the patent that 19 tech companies are allegedly infringing according to a complaint filed by Wi-LAN on April 7, 2010.

Among the companies Wi-LAN is accusing of patent infringement are technology giants Dell, Texas Instruments, Motorola, Intel, Apple and Sony. Wi-LAN claims the companies are infringing their ?369 patent because they use ?products with wireless capability compliant with the Bluetooth standards.?

However, despite Wi-LAN?s claims, an in-depth analysis of patent ?369 and of the Bluetooth specifications by Patent Calls finds otherwise. Patent Calls' analysis concludes that compatibility with the Bluetooth standard does not require infringement of Wi-LAN?s ?369 patent, and that the Bluetooth standard is different from the claimed elements of the patent.
