Apple Found Guilty Of Using University Of Wisconsin Patent, May Face Hefty Fines

Apple Inc. has been found guilty of using a patent owned by the University of Wisconsin-Madison through its patenting arm, the Wisconsin Alumni Research Foundation (WARF). According to the Special Verdict released in the United States District Court for the Western District of Wisconsin, it was found that with a significant amount of evidence, WARF has proven that Apple had, indeed, infringed on its claims towards one of its patents. Moreover, the jury had ruled that Apple failed to prove that WARF’s claims to the patent in question is invalid.


The patent that took the two parties to court involves a “table based speculation circuit for parallel processing computer,” which also known as the ‘752 patent based on its United States Patent No. 5,781,752. The said patent was developed by WARF inventors Andreas Moshovos, Scott Breach, Terani Vijaykumar, and Gurindar Sohi. According to the complaint filed by WARF, these investors are the lead researchers in computer microprocessor architecture. They dedicate their work to improving the efficiency and performance of computer processors today.

Dr. Sohi led the development of the ‘752 patent. According to the patent application WARF had filed back in 1996, the ‘752 patent involves a predictor circuit that allows for advanced execution of instructions dependent on previous instructions data. With regards to this capability, the complaint alleges that Apple incorporated the ‘752 patent technology into their A7 processor in order to improve its efficiency and performance. Moreover, the said processor is now found in Apple’s iPhone 5s, iPad Air and iPad Mini with Retina Display. According to a report from Reuters, Apple Inc. may be liable for as much as $862 million in damages following the jury’s decision.
