Recently, Apple had requested that the entire Federal Circuit of Appeals, made up of 9 judges, hear the case at once in what is known as an en banc review. Apple was seeking a reinstatement of the sales ban on the Samsung GALAXY Nexus that was put into place last Summer before being overturned. It is very rare to get such a review, so the fact that Apple's request was denied is not exactly a surprise. The patent in question is the '604 patent, also known as the Siri patent, which deals with universal search on a smartphone. To get the sales ban, Apple would have had to prove that demand for the Samsung GALAXY Nexus was from the infringing feature, something hard to prove in this day and age of feature-rich smartphones.
Apple could decide to appeal the decision to the U.S. Supreme Court, but usually business conflicts like this one do not meet the guidelines of a Supreme Court case.
