First: I am unable to confirm that there has been a decision in the DRAM case appeal. Second: if my summary of the main issue is correct (and please reply there if you know something on the subject), loss in the appeal would be a very minor negative. It would make compensation for the patent infringement which has been found to have occurred in the DRAM business an issue in the Amkor arbitration rather than a separate issue.
Since the technical issue here MIGHT be of interest to SCOTUS, the courts might not be any faster than the arbitration process. (The less-interesting DRAM case ought to end in a year or less; the arbitration in about 1.5 years.)
