Apple was hoping to get one of the patents in the case invalidated, but today, the U.S. Court of Appeals for the Federal Circuit ruled against Apple and declined to invalidate the patent in question, upholding a prior decision from an administrative patent court.
According to Reuters, Apple tried to get the patent invalidated on “obviousness” grounds, suggesting the patent was an invention that came from standard product design and development and is obvious to experts.
The lawsuit dates back to 2016, when Caltech sued Apple and Broadcom for infringing on a series of patents granted between 2006 and 2012. The patents related to IRA/LDPC codes that use simpler encoding and decoding circuity for improved data transmission rates and performance, with the technologies used in the 802.11n and 802.11ac Wi-Fi standards supported by many Apple products.
Caltech claimed that Apple was infringing on four patents with the iPhone, iPad, iPod touch, Mac, Apple TV, Airport routers, and Apple Watch, and demanded a jury trial along with preliminary and permanent injunctions against Apple products in the U.S. that use Caltech technology.
A jury in January ruled in Caltech’s favor, ordering Broadcom to pay $270 million and Apple to pay $838 million. Apple still plans to appeal the verdict.
