Apple Inc. has been ordered by U.S District Court Judge William Conley to pay more than double what the original jury decided. The latest figures for Apple to pay the University of Wisconsin are $506 million.

The original patent infringement case began in 2014 when WARF (Wisconsin Alumni Research Foundation) sued Apple for infringing on its US Patent No. 5,781,752 for a “table based data speculation circuit.” In 2015, the case drew to a close when a jury found Apple guilty of infringing on a patent for chip technology developed at the university and $234 million in damages were awarded to the university foundation. However, the technology was used by Apple in its processors in a number of its products, hence the judge’s decision to work on a final figure with Apple and the foundation based on the number of units sold that contained the technology. The final breakdown of payments in the decision was $1.61 per unit for many of the iPad and iPhone devices that use the accused chips, up until the entry of judgment in October 2015 and $2.74 per unit as a royalty payment covering the period from the date of judgment through December 26, 2016, which is when the ‘752 patent expired.

This totaled, after adding some court costs and post-judgment interest, $506 million.

Apple has already filed papers to appeal the jury’s verdict. A second WARF lawsuit against Apple, accusing a newer generation of products, is on hold while Apple appeals the first verdict. At the time of writing, no official comments or statements have been made by Apple or WARF.
