Apple faces damages bill after jury finds iPhone and iPad chip violates processor patent

Technology that improved processor efficiency was used in Apple devices but belonged to University of Wisconsin-Madison, jury decides

Apple Inc could face up to $862m in damages after a US jury on Tuesday found the company used without permission technology owned by the University of Wisconsin-Madison's licensing arm in chips found in devices including the iPhone 6 and 6 Plus and several versions of the iPad.

The jury in Madison, Wisconsin, also said the patent, which improves processor efficiency, was valid. The trial will now move on to determine how much Apple owes in damages.
