The University of Wisconsin's patent licensing division has sued Apple over patent infringement in the company's A7 chip.
According to the Wisconsin Alumni Research Foundation (WARF), the technology was invented by the University's computer scientists, Andreas Moshovos, Scott Breach, Terani Vijaykumar, and Gurindar Sohi.
The iPhone's A7 chip has now been accused of violating its 5,781,752 patent known as "Table based data speculation circuit for parallel processing computer".
The patent was filed in 1996 and states: "A predictor circuit permits advanced execution of instructions depending for their data on previous instructions by predicting such dependencies based on previous misspeculations detected at the final stages of processing."
WARF claims Apple had clear knowledge of its patents and employed the patented technology to get more efficiency and performance out of the chip.
