On June 24, 2016, Qualcomm sued Meizu for infringing its patents related to 3G and 4G wireless communication standards and submitted a complaint to the Beijing Intellectual Property Court. Then Meizu launched a media communication meeting on June 28, the fourth day after being sued by Qualcomm, to express its attitude on Qualcomm's lawsuit against Meizu.

On June 30, 2016, Qualcomm said that Meizu has always lacked the willingness to reach a patent license agreement with Qualcomm on the basis of the terms of the aforementioned rectification scheme through honest negotiations, and refused to pay Qualcomm the cost of using its valuable technology. Qualcomm once again accused and added Meizu of infringing a number of patents covering various functions and technologies of smart phones, and submitted the pleadings of these lawsuits to Beijing Intellectual Property Court and Shanghai Intellectual Property Court.

Qualcomm said Meizu has always chosen to delay and refused to negotiate with Qualcomm in good faith. Qualcomm made a final offer to Meizu in April 2016, and Meizu did not respond to this. Don Rosenberg, executive vice president and general counsel of Qualcomm Incorporated, said: "Although Meizu has admitted to selling products that infringe Qualcomm's valuable Chinese patents, it has always refused to negotiate with us in good faith. Meizu tries to gain unfair and unreasonable cost advantages through competition.

It is known that at present, more than 100 Chinese companies have reached patent license agreements with Qualcomm. Qualcomm can maintain a fair and just competitive environment for these companies that respect patent rights only by initiating litigation. The contents of these signed patent license agreements are consistent with the rectification plan reached by Qualcomm and the National Development and Reform Commission. "
