Apple has successfully appealed a court decision against the University of Wisconsin that argued the iPhone maker had infringed upon patents used for its A-series chips.
The University of Wisconsin-Madison’s Wisconsin Alumni Research Foundation (WARF) successfully argued Apple had infringed upon its integrated circuits patents in 2015, with a ruling that resulted in a $506 million fine for Apple. It cited processor technology used in the iPhone 5S, iPad Air and iPad mini 2.
In the subsequent years, Apple continued to fight the lawsuit in court and finally prevailed with the US Federal Circuit Court of Appeals overturning the ruling. The ruling has tossed out Apple’s initial $234 million fine, with the $272 million remaining balance likely to be tossed out as well now that the case has been overruled.
Apple’s vigor in fighting the lawsuit had less to do with it paying the fine and more to do with fighting scrupulous lawsuits. In the end, Apple’s tenacity prevailed with a victory.
