Two NRI engineers sue Apple for patent infringement and win

INITIA2engrsA federal jury has ruled that the tech giant Apple has used technology patented by Gurindar Sohi, Terani Vijaykumar and two others when developing processors for some recent iPhones and iPads.

The two engineers were named in the lawsuit brought by the Wisconsin Alumni Research Foundation, the University of Wisconsin’s licensing arm, as two of four inventors whose patent Apple had used without permission to enhance performance of their signature products.

In court documents, Apple said the patent was invalid and that it did not infringe on it.

The University has sought over $800 million in damages from the tech giant but the jury has yet to rule on the sum.

Mr. Sohi, a professor of computer sciences at the University of Wisconsin Madison led the lab that developed a 1998 patent on improving efficiency in computer processors. Mr Vijaykumar, who got his doctorate in computer science at the University of Wisconsin in 1997, is now a professor of electrical and computer engineering at Purdue University in Indiana.
