Caltech has filed a lawsuit against Broadcom and Apple and alleges the two firms are using its patented technology without permission.
The patents in question, granted to Caltech between 2006 and 2012, cover 802.11n and 802.11ac WiFi technologies, which improve transmission speeds and reduce the hardware needed for WiFi radios. Caltech says the iPhone 5 and all subsequent iPhones violate the patents. It is seeking to halt sales of the devices and recover monetary damages.
The WiFi modules in question were made by Broadcom. Neither Apple nor Broadcom commented on the matter.
