UPDATED 18/10: Qualcomm has taken actions in France, Germany and the US “to address Meizu’s infringement of its patents,” following earlier suits filed in China.

“Meizu’s refusal to negotiate a license agreement in good faith and its sales and distribution of infringing products around the world leave Qualcomm with no choice but to protect our patent rights through these additional legal proceedings,” said Don Rosenberg, executive vice president and general counsel.

The US company filed a complaint with the US International Trade Commission, a patent infringement action with the Mannheim Regional Court in Germany, and an infringement-seizure action in France to obtain evidence for a further infringement case.

In a statement to Mobile World Live, Meizu said it had “worked with Qualcomm to advance towards an agreement.” It added: “We respect Qualcomm’s right to use legal measures if they are unsatisfied with the progress, but still welcome them to proceed the negotiations with us at any time.”

Qualcomm first compiled a Meizu complaint in June, having failed to negotiate a deal with the company. At this point, it called on the Beijing authorities to review the contract offered.

This was followed by 17 more complaints, with Qualcomm arguing that Meizu was “attempting to obtain an unfair and improper cost advantage over its competitors”.
