A $10 million licensing breach of contract dispute by IBM against Taiwan-based semiconductor company United Microelectronics Corp. will return to the district court for additional review, after the U.S. Court of Appeals for the Second Circuit partially reversed a trial court ruling in IBM’s favor.

In September 2017, U.S. District Judge William Pauley III of the Southern District of New York granted IBM’s motion for summary judgment over what the American tech giant claimed was UMC’s breach of contract for failure to pay a $10 million intellectual property licensing fee.
