The processor inside the iPhone 5s, and later, inside the iPad Mini with Retina Display, as well as the iPad Air, is Apple’s latest 64-bit A7-chip. Whether the new architecture brings any utility, features, or speed to devices is powers is not the topic of debate here, but the very raison d’être. Apple has been sued over acts of infringement which are claimed to be willful and intentional, by the plaintiff.
The plaintiff – the Wisconsin Alumni Research Foundation (WARF) on behalf of the University of Wisconsin — claims that Apple has violated its own patent no. 5,781,752, referring to a “table based data speculation circuit for parallel processing computer”. Its descriptions states: “a predictor circuit permits advanced execution of instructions depending for their data on previous instructions by predicting such dependencies based on previous mis-speculations detected at the final stages of processing. Synchronization of dependent instructions is provided by a table creating entries for each instance of potential dependency. Table entries are created and deleted dynamically to limit total memory requirements“.
WARF claims that not only Apple has used the patented technology in its chips to achieve greater efficiency and performance, but has done infringing acts in a willful and intentional way. “WARF is informed and believes, and on this basis alleges, that the acts of infringement by Defendant have been, and continue to be, willful, intentional, and in conscious disregard of WARF’s rights in the ’752 patent”, says the filing, and WARF has asked the court to order a fine, while also stopping Apple from infringing its patent.
