Qualcomm submitted a complaint about the problem in 2017. The patents relate to allowing telephones to connect to the Internet quickly after they are switched on; battery efficiency and graphic processing; and a traffic management function that allows apps to download data faster.
According to CNET Apple claimed that an engineer named Arjuna Siva made essential contributions to the start-up technology while working for the company and should have been listed on that patent. However, Siva (now a Google employee) finally decided not to testify during the San Diego trial and the jury dismissed Apple's argument.
Apple also claimed that the lawsuit was in fact a retaliatory action by Qualcomm because Apple had added Intel in 2016 as another vendor. Qualcomm has been the exclusive supplier of Apple since 2011 – Intel's components have now replaced Qualcomm's in iPhones.
The ruling anticipated a greater legal battle between the two companies over royalty payments. A lawsuit in that case is planned for next month, also in San Diego, with billions of dollars at stake. The result of another trial with the parties, which took place in January, is pending. Apple, Intel and the Federal Trade Commission have accused Qualcomm of having a monopoly on telephone modems.
The struggle between Qualcomm and Apple has also been played out in other countries. Qualcomm won an order in December against Apple in Germany, which banned the sale of some older iPhones in the country. Apple later started selling iPhone 7 and iPhone 8 again in Germany after exchanging Intel modems for Qualcomm's there.
