Apple, Caltech alleges, has been using Wi-Fi technology it oughtn't.
In a suit filed with the US District Court for the Central District of California, the university claims that Apple has infringed four of its patents for improved data transmission rates and performance over Wi-Fi.
These patents were awarded between 2006 and 2012, and cover technology implemented in the most recent 802.11n and 802.11ac Wi-Fi standards. As MacRumors reports, a number of iPhone, iPad, Mac and Apple Watch devices incorporate this technology.
The lawsuit also names Apple supplier Broadcom, who is one of Apple's main suppliers of Wi-Fi chips. The suit seeks a jury trial against Apple and Broadcom, as well as a court order to prevent Apple from selling the devices in the US, and damages for the infringed patents. The university could very well win: Last year Apple was ordered to pay damages for infringing a patent owned by the University of Wisconsin-Madison.
Apple did not immediately reply to a request for comment.
