IIRC the ITC can rule that patents are invalid (or not infringed). ITC trials are more expedited than patent trials in District Courts, and an appeals court would also do a deeper dive. But that doesn't mean that the ITC's determination of infringement doesn't indicate that the ITC also found them to be valid. It's also possible that Apple didn't raise this argument at the ITC trial, but that would be very unlikely (it's one of the most obvious arguments to make when being sued for patent infringement).
