Every time I turn around, someone's suing Android directly or by proxy--the latest being Microsoft's patent-infringement lawsuit against Motorola launched this past Friday. In the suit, Microsoft alleges that nine of its patents were violated.
This is the third time software makers have gone after Android or Android-based phones this year. In March, HTC found themselves in Apple's cross hairs as another proxy against Google's Android, with another patent lawsuit. This summer, Oracle went straight at Google, claiming its Java code was being improperly used in Android.
