Following the $ 1 billion payment order for infringement of some patents belonging to the California Institute of Technology, Apple had requested that one of the patents in the lawsuit be found invalid. However, the judges rejected this request.
The United States Court of Appeals ruled against Apple’s request for a review of the initial decision. Apple has focused in particular on U.S. Pat. 7.116.710, which among other things covers the “method of coding a signal“.
Apple contested the patent in question for reasons of obviousness, stating that patented technology is too generic and therefore cannot be the subject of any dispute.
The lawsuit started in 2016, as Caltech claimed that WiFi chips made by Broadcom and used by Apple violated several patents. The lawsuit cited all Apple products: iPhone, iPad, Mac, iMac, Apple Watch, Apple TV, HomePod and even discontinued AirPort routers. The patents concern coding systems that correct errors in data transmission used in the 802.11 Wi-Fi standard. Apple and Broadcom denied infringement of all patents and claimed that the California Institute of Technology was not entitled to receive any damages.
Apple will therefore have to pay $ 838 million, while the rest will be paid by Broadcom.
