The lead attorney for the group of Apple Inc device assemblers seeking at least $9 billion in damages from Qualcomm Inc said on Sunday the contract manufacturers are not in settlement talks with the mobile chip supplier and are “gearing up and heading toward the trial” in April.

Axar.az reports citing Reuters.

The conflict is but one aspect of the global legal battle between regulators, Apple and Qualcomm, which supplies modem chips that help phones connect to wireless data networks.

Last week, Qualcomm secured a preliminary victory in a patent lawsuit in China that would have banned sales of some Apple iPhones there. Apple later said it believed it was already in compliance but would change its software “to address any possible concern” about its compliance.

But Qualcomm was also handed a setback in an antitrust lawsuit brought against it by the U.S. Federal Trade Commission when a judge said it will not be able to mention that Apple ditched Qualcomm chips for competing ones from Intel Corp when the case goes to trial next month.
