The jury determined Apple's A7, A8, and A8X system-on-a-chip (SoC) designs infringed on the asserted claims of the patent.
The chips are found in the Apple iPhone 5s, iPhone 6, iPhone 6 Plus, and several different iPad models.
The patent dates back to 1998 and covers processor efficiency. While WARF -- which manages inventions created by researchers at the school -- said it offered to license the patent to Apple, the iPhone maker refused to entertain the idea.

"This is a case where the hard work of our university researchers and the integrity of patenting and licensing discoveries [have] prevailed," Carl Gulbrandsen, managing director of WARF, wrote in an Oct. 16 statement. "The jury recognized the seminal computer processing work that took place on our campus. This decision is great news for the inventors, the University of Wisconsin-Madison and for WARF."
In the first phase of the two-phase trial, the federal jury found that Apple was guilty of infringing on the asserted claims and determined the patent claims to be valid.
The issues of infringement and validity took the jury six hours to deliberate in WARF's favor.
The second phase of the trial determined Apple owned WARF $234 million in damages, a far cry from the $400 million the foundation was seeking, but far more than Intel paid to settle a similar dispute over the same patent.
Apple had initially sought to have the patent declared invalid, but the US Patent and Trademark Office denied Apple's request to examine the patent's merits, and so allowed the trial to move forward.
"For 90 years, WARF has helped UW faculty take intellectual property, patent it and reinvest the licensing fees from those patents back into research and education at the University of Wisconsin-Madison," Gulbrandsen said. "Although patent verdicts like this one are typically appealed, we hope to continue to work with Apple to resolve this matter and build a stronger relationship between our two institutions."
Patent lawsuits have become a familiar tactic in the battle for smartphone market supremacy. Apple has locked horns with Samsung over patents since 2011.
The companies settled most of their pending lawsuits around the world, but are still tussling over a 2012 court decision that initially awarded Apple $1.05 billion.
Apple is of course not stranger to lawsuits on several fronts. In May, the company settled a lawsuit filed against it by lithium-ion battery manufacturer A123, which sued Apple after five employees left the company to work for Apple. The complaint argued that the five violated their employment agreements.
The two companies signed a settlement agreement, but neither company commented on the development. Terms of the arrangement were not disclosed.
