The U.S. International Trade Commission said that it is going to review a decision reached in December regarding a patent lawsuit between Microsoft and Motorola. The court issued a preliminary ruling against Motorola, saying that it infringed on one out of nine Microsoft smartphone patents. The review will take several months to complete. "We remain confident that the commission will affirm that Motorola has infringed our intellectual property," said Microsoft legal representative David Howard. Microsoft licenses Android-related patents to a number of smartphone makers. Motorola is one of the only companies with which Microsoft has not struck a licensing agreement.
