Qualcomm Inc. said June 23 that it took legal action against the Chinese company Meizu, filing a complaint in the Beijing Intellectual Property Court.

In a statement distributed to the media, Qualcomm (Nasdaq: QCOM) alleged that Meizu is “unfairly expanding its business through the use of Qualcomm’s innovations without compensating Qualcomm for the use of Qualcomm's valuable technologies.”

The San Diego business said it has negotiated extensively and in good faith to get Meizu to sign a patent license agreement. Qualcomm also said it has reached license agreements with more than 100 other Chinese firms under terms laid out by Chinese regulators in early 2015.

Specifically, the complaint “requests rulings that the terms of a patent license offered by Qualcomm to Meizu comply with China’s Anti-Monopoly Law, and Qualcomm’s fair, reasonable and non-discriminatory licensing obligations,” Qualcomm said in a statement. “The complaint also seeks a ruling that the offered patent license terms should form the basis for a patent license with Meizu for Qualcomm’s fundamental technologies patented in China for use in mobile devices … .”
