Qualcomm has cried foul over allegations of unfair licensing practices. The company has hit back against the six companies who filed a complaint to the European Commission and claimed that the six may simply be trying to renegotiate their licensing fees.

Last week,the six companies, including Nokia and Ericsson, complained formally charging Qualcomm with anti-competitive behaviour. They allege that Qualcomm failed to adhere to agreements it made when it contributed its patents to the WCDMA (Wideband Code Division Multiple Access) standard. WCDMA is the industry standard most European regulators have adopted for 3G (third generation) mobile networks.

Theyalso accuses Qualcomm of using its patents as an unfair advantage in the market, forcing third-party chip suppliers to charge a higher price than Qualcomm because the company essentially discounts the price of its patents when it sells its own chipsets.

Qualcomm called the allegations "factually inaccurate and legally meritless" and vowed to vigorously defend itself, in a statement late Friday.

The company also said the action by the companies "appears to be nothing more than an attempt by these licensees to renegotiate their license agreements by seeking governmental intervention," Qualcomm said.

"We welcome the opportunity to demonstrate these facts in an open and public process," Qualcomm said.
