Qualcomm filed the case over the issue in 2017. The patents apply to allow phones to quickly connect to the Internet after they are turned on; battery efficiency and graphics processing; and a traffic management feature that lets apps download data faster.
According to CNET, Apple claimed that an engineer named Arjuna Siva made important contributions to the startup technology while working for the company and should have been called on this patent. However, Siva (now a Google employee) eventually chose not to testify in the San Diego test, and the jury turned down Apple's argument.
Apple also claimed that the lawsuit was in fact a retaliation by Qualcomm for Apple to add Intel as another chip provider in 201
The hearing led to a major legal battle between the two companies over royalty payments. A trial period in that case has been scheduled for next month, even in San Diego, with billions of dollars at stake. The result of another attempt involving the parties, which took place in January, is pending. Apple, Intel and the Federal Trade Commission have accused Qualcomm of having a monopoly on modems in phones.
The interplay between Qualcomm and Apple has also played out in other countries. Qualcomm won an order against Apple in Germany in December, banning the sale of some older iPhones in the country. Apple later began selling the iPhone 7 and iPhone 8 in Germany again after replacing the Intel Intel modems for Qualcomm.
