The long running patent battle between Apple and Samsung (now in year four) won't be ending anytime soon. Though a federal court had found that Samsung violated Apple's "slide to unlock" and auto-linking patents, it also refused to enjoin Samsung from selling those patent infringing products. According to the court, Apple simply couldn't show that Samsung's patent infringing features were harming its sales.
That was the wrong standard, the Federal Circuit ruled. Apple didn't have to show that a Galaxy phone's slide to unlock feature was directly connected to a loss of sales. A simple loss of sales due to Samsung is enough. Samsung will likely be forced to pull those phones from the market as a result of the ruling.
