A Seoul court on Thursday ruled that Apple’s iPhone and iPad models did not violate Samsung’s patents as claimed by the South Korean handset maker.

The technology in two of Samsung’s patents could easily be independently developed by others, Judge Shim Woo-yong said, making it unlikely they were copied. He said one patent was not used in the iPad, according to a TIME report.

Samsung Electronics Co. had filed a suit against Apple in March 2012 accusing it of illegally using its three patented technologies. It sought compensation and a ban on sales of six iPhone and iPad models, which include models still available in the market, such as the model with Retina display known as the fourth-generation iPad.

The judge said a similar technology exists with the Samsung patent that allows users to activate another application while typing text messages without losing the messages. Another technology that enables users to touch a notification box to check a full message can be invented easily, he said.

Samsung and Apple are locked in multiple lawsuits against each other over mobile technology patents.

In November, a federal jury in San Jose, Calif., ordered Samsung to pay Apple $290 million in damages for infringing Apple patents in a retrial. The ruling came on top of an original $640 million award that wasn’t in dispute in the retrial.
