Qualcomm has filed a complaint against Meizu in the Beijing Intellectual Property Court, seeking a rulling that affirms the patent licensing deal between the companies. 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.

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, including those relating to 3G (WCDMA and CDMA2000) and 4G (LTE) wireless communications standards.

Qualcomm says it has negotiated extensively and in good faith with Meizu to sign a patent license agreement consistent with the terms of the rectification plan submitted by Qualcomm to, and accepted by, China’s National Development and Reform Commission (NDRC) in 2015. Qualcomm says it would prefer to reach a resolution with Meizu without the need for litigation, but Meizu "has been unwilling to negotiate in good faith and enter into a license agreement on the rectification plan terms while unfairly expanding its business through the use of Qualcomm’s innovations without compensating Qualcomm for the use of Qualcomm’s valuable technologies."
