World’s leading mobile phone manufacturer Nokia and top mobile technology providers Ericsson and Broadcom as well as other companies including Panasonic, NEC and Texas Instruments have withdrawn their complaints to the European Union concerning Qualcomm violating antitrust laws.

The EU has dropped the four year long antitrust probe, in consequence. “All complainants have now withdrawn or indicated their intention to withdraw their complaints,” an EU statement writes. “[The European Commission] does not consider it appropriate to invest further resources in this case.”

Qualcomm was accused in 2005 of overcharging Ericsson, Nokia, Panasonic, NEC and Texas Instruments for the use of essential technology for Europe’s 3G mobile phone standard and for the development of the 4G standard. The companies have complained to the EU that Qualcomm was violating antitrust laws and rising prices to mobile technology manufacturers that caused higher retail prices for mobile services.

However, after four years with no clear results the companies have decided to withdraw their complaints. “We have decided to spend our resources otherwise,” said Ericsson spokeswoman Nina Macpherson.
