Apple AAPL latest hurdle in the world of patent disputes could blow a small hole in its $200 billion cash mountain.
A U.S. federal jury has ruled that Apple used technology owned by the licensing arm of the University of Wisconsin on some of the chips that found their way into recent iPads and iPhones.
The jury has yet to decide on damages but the University has been seeking as much as $862 million for patent infringement.
The University filed the patent in 1998, for technology that could enhance the efficiency of computer processors.
It sued Intel INTC for infringing on the same patent in 2008, and settled out of court with the company before it could go trial. Intel ended up paying the University a $110 million lump sum to license the patent, court documents show.
