Microsoft and Samsung Electronics Co Ltd have settled a contract dispute over patent royalties, though terms of the settlement are confidential, Microsoft said in a statement on Monday. Microsoft sued Samsung last year in a federal court in New York, accusing Samsung of breaching a collaboration agreement by initially refusing to make royalty payments after the U.S. company announced its intention to acquire Nokia’s handset business in September 2013. The lawsuit claimed Samsung still owed $6.9 million in interest on more than $1 billion in patent royalties it delayed paying.
