A California jury on Thursday awarded Apple Inc. (NASDAQ:AAPL) $290 million in additional damages, in the latest chapter of a multi-year legal battle against South Korean tech giant Samsung Elec Co Ltd (NASDAQ:SSNLF).

In August 2012, Samsung was found guilty of infringing Apple patents in 26 devices, and a jury awarded Apple more than $1 billion in damages, CNN reported. In March 2013, U.S. District Court Judge Lucy Koh ruled that the jury in the original case had miscalculated the damages for 13 devices, and slashed the award by about $450 million.

Thursday’s ruling means that Samsung now owes Apple an additional $290 million on top of the original $640 million that Judge Koh upheld in the original trial, according to CNN. Apple had demanded another $379 million, while Samsung argued that it should only have to pay $52 million.

The amount of total damages is now $935 million, CNN noted. The decision was reached by a California jury on the third day of deliberations.

“We are disappointed by today’s decision, which is based in large part on a patent that the U.S. Patent and Trademark Office has recently deemed invalid,” said a Samsung spokeswoman, according to the Wall Street Journal. “While we move forward with our post-trial motions and appeals, we will continue to innovate with groundbreaking technologies and great products.”

“For Apple, this case has always been about more than patents and money. It has been about innovation and the hard work that goes into inventing products that people love. While it’s impossible to put a price tag on those values, we are grateful to the jury for showing Samsung that copying has a cost,” Apple spokeswoman Kristin Huguet said in a statement.

According to CNN, both companies have appealed the original August 2012 ruling, which could invalidate Thursday’s decision.
