In one example, Apple claimed that the Quick Search Box used on the Nexus infringes one of its patents. But this search box is a feature of Android, not something specific to the Nexus.
"The release of the allegedly infringing version of the Android platform predates the release of the Galaxy Nexus, but Google is not a defendant in this suit," the appeals court said.
In another example, Apple tried to establish a "causal nexus," or a link between a cause and its effect, asserting that it would suffer harm without a ban on the Galaxy Nexus. But the appeals court determined that the district court "abused its discretion" in finding that Apple established such a causal nexus.
In one more example, Apple asserted that the Nexus uses the "unified search feature" in Siri, which was patented by Apple even though Samsung's phone offers no equivalent to Siri. But again the appeals court disagreed with the lower court's findings.
"To establish a sufficiently strong causal nexus, Apple must show that consumers buy the Galaxy Nexus because it is equipped with the apparatus claimed in the '604 patent -- not because it can search in general, and not even because it has unified search," the appeals court said. "The district court made no such determination."
