WARF Doubles Down Against Apple
Wisconsin Alumni Research Foundation (WARF), the nonprofit, patent management arm of the University of Wisconsin, filed a second suit (3:15-cv-00621) against Apple alleging infringement of a single patent (5,781,752). WARF accused Apple in a January 2014 lawsuit, also in the Western District of Wisconsin, of infringing the ‘752 patent through the sale of its products incorporating an A7, A8, or A8x processor. This second suit targets Apple products that incorporate an A9 or A9x processor, including the iPhone 6S, iPhone 6S Plus, and iPad Pro. The ‘752 patent generally relates to preventing microprocessors capable of performing commands out of their sequential order from committing errors by tracking when out-of-order commands caused problems in the past. The named inventors are four University of Wisconsin researchers.
