Caltech Patent Not Ruled Invalid

Apple challenged the patent on “obviousness grounds,” according to reports. The alleged infringement relates to Apple’s use of Broadcom’s technology, which Caltech says uses IRA/LDPC encoders/decoders invented by the school. Amongst the products said to be using the allegedly patent infringing technology are iPhones from the iPhone 5 onwards, iPads, and MacBook Airs. Apple and Broadcom have consistently denied any wrongdoing.  Apple has said it will appeal the verdict.
