Judge Thomas Pender recently ruled that Apple's iPhone doesn't infringe on a patent owned by Motorola Mobility. The patent in question helps prevent the phone from accidentally ending an active phone call, and Google-owned Motorola Mobility isn't happy with the ruling.

"We're disappointed with this outcome and are evaluating our options," a spokesperson told Bloomberg. This is the second time that Apple has won a suit levied against it by Motorola Mobility. The first suit charged Apple with infringing on 3G patents. There remain several ongoing cases between the two firms, however. Apple is currently arguing that Motorola Mobility isn't providing fair terms for licensing its patents in an appeals court, after a judge tossed the case in November.

Motorola Mobility won a lawsuit against Apple last May related to a finger swipe patent, however.
