CWmike writes: "A U.S. trade judge has rejected Google's move to block the testimony of a Microsoft expert witness in the dispute with Motorola over patents allegedly used by Android. The judge denied Google's motion to prevent the expert hired by Microsoft from testifying about the Android source code at an upcoming hearing. Last week, Google accused Microsoft of violating a confidentiality agreement struck between Microsoft, Motorola and Google in the ITC case. The judge rejected Google's motion on Monday. 'The ALJ [Administrative Law Judge] finds no basis to discern from Google's statement whether Google made a reasonable, good-faith effort to resolve the matter with Microsoft,' he wrote in his ruling."
