Apple originally sued Samsung in 2014, alleging infringement of numerous patents covering smartphone features, including slide-to-unlock, autocorrect and other graphical user interface elements.
A US District court ordered Samsung to pay $119.6 million, but Samsung appealed to the US Court of Appeals for the Federal Circuit, which reversed the decision.
Apple filed a petition for an en banc rehearing, in which the full panel of Federal Circuit judges overturned the previous ruling.
Samsung then appealed to the Supreme Court in March, arguing that the case was of “great importance to patent law” and arose from the decisions of a “deeply divided Federal Circuit”.
US solicitor general, Noel Francisco, filed an amicus curiae in the case, siding with Apple and concluded that Samsung’s appeal should be denied.
Apple and Samsung’s previous foray at the Supreme Court resulted in a reversal of Apple’s $399 million win over design patents at the Federal Circuit.
A new trial has since been ordered at the US District Court for the Northern District of California.
