writes "An International Trade Commission judge has issued a preliminary ruling that Motorola Mobility infringed one of Microsoft's patents. The disputed patent covers storing a meeting request on a mobile device, and was rejected by the European Patent Office as being "obvious". The judge also ruled that six other Microsoft patents were not being infringed. Experts say that this will strengthen Microsoft's hand in collecting patent fees on Android. Microsoft recently claimed that it now collects patent fees on over half of all Android devices sold."
