Apple's potential damages in a patent fight with the University of Wisconsin's licensing body could reach $400 million as a trial on the amount Apple owes for infringing a processor patent got under way on Wednesday, two people familiar with the case said.
The figure is less than half the amount that U.S. District Judge William Conley cited last month as the Wisconsin Alumni Research Foundation's maximum claim for damages.
In a pre-trial ruling on Sept. 29, Conley refused a request by Apple to limit damages in the case. He said WARF's maximum claim was $862.4 million, citing Apple's own figures.
On Tuesday, a federal jury in Madison, Wisconsin said Apple violated a patent owned by WARF, which helps improve chip efficiency. The jury also said that the patent was valid.
But heading into the damages phase of the trial on Wednesday, WARF's claim is approximately $400 million, according to sources from both sides speaking on background as the trial is ongoing.
