Samsung and Apple's patent lawsuit has been ongoing for several years now, some of Samsung's devices were found to be infringing on Apple's utility patents, and even though the company is still trying to fight its rival despite agreeing to pay over half a billion dollar in damages this time around it's a win for Apple. Its wish for a sales ban on infringing Samsung devices has been granted as a result of which the company can no longer sell those devices.
Apple may have won a sales ban but it's effectively useless since all of those devices are outdated anyway and Samsung doesn't sell them anymore. The devices that it can no longer sell in the United States include the Galaxy Nexus, the first Galaxy Note, the Galaxy Note 2, the Galaxy S2, the Galaxy S2 Skyrocket, the Galaxy S3 and the Stratosphere. Samsung is trying to get the US Supreme Court to take up the matter and reform patent law to fit modern devices and many have thrown its weight behind the company, but until that happens this ban will remain in place.
