In a case filed in federal court in Los Angeles in 2016, the Pasadena, California-based research university alleged that Broadcom wi-fi chips used in hundreds of millions of Apple iPhones infringed patents relating to data transmission technology.

"While we thank the members of the jury for their service, we disagree with the factual and legal bases for the verdict and intend to appeal", Broadcom said in a statement.

Apple said it plans to appeal the verdict. The company had said in court filings that it believed all of the university's claims against it resulted from it using Broadcom's chips in its devices, calling itself "merely an indirect downstream party".

The verdict awarded CalTech $837.8 million from Apple and $270.2 million from Broadcom.

CalTech said in a statement: "We are pleased the jury found that Apple and Broadcom infringed Caltech patents. As a non-profit institution of higher education, Caltech is committed to protecting its intellectual property in furtherance of its mission to expand human knowledge and benefit society through research integrated with education."
