Apple must pay $300 million in royalties following a retrial in a patent dispute, a Texas jury determined Friday. The jury found that Apple should pay patent company Optis Wireless Technology and its related companies because the technology Apple allegedly infringed Optis’ patents.

It was not all bad for Apple, the Texas jury wanted Apple to pay Optis $506 million in the dispute, but a judge vacated that award in April, and ordered a new trial focused on damages only.

US District Judge Rodney Gilstrap said the first jury had not been allowed to consider whether the amount was awarded on the “fair, reasonable, and non-discriminatory”, or FRAND, terms required in standard-essential patent cases.

The five patents involved in the case once belonged to LG, Panasonic, and Samsung, but were obtained by Optis.

An Apple spokesperson said that the company was disappointed by the verdict and plans to appeal. It claims it is the victim of a patient troll.

“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.”
