Northern District of California Judge William Alsup has granted summary judgment of noninfringement for Amazon in a case from inventor-controlled MasterObjects, Inc. In a September 15 decision, Judge Alsup held that the plaintiff could not prove literal infringement of an auto-complete search patent under the proper construction of certain key claim limitations, leaving only the issue of infringement under the doctrine of equivalents for possible resolution prior to a scheduled October trial. The ruling follows another, similar setback in one of the first two lawsuits filed in the long-running MasterObjects campaign.
