A U.S. jury has awarded Optis Wireless Technology LLC and several related companies $300 million in damages in a second patent trial against Apple Inc.

Previously, the jury had found that Apple had infringed on five Optis wireless standard essential patents and had awarded $506 million in damages; however the U.S. District Judge Rodney Gilstrap in Marshall, Texas, vacated that award in April and ordered a new trial to determine the amount of damages.

“Optis makes no products and its sole business is to sue companies using patents they accumulate. We will continue to defend against their attempts to extract unreasonable payments for patents they acquire,” said Apple.
