Microsoft has filed patent infringement lawsuits against Barnes and Noble “based on the Redmond company’s assertion that the Android operating system violates its intellectual property.” According to Microsoft, “the patents in dispute ‘cover a range of functionality embodied in Android devices that are essential to the user experience, including: natural ways of interacting with devices by tabbing through various screens to find the information they need; surfing the Web more quickly, and interacting with documents and e-books.'”

The Android platform infringes a number of Microsoft’s patents, and companies manufacturing and shipping Android devices must respect our intellectual property rights. To facilitate that we have established an industry-wide patent licensing program for Android device manufacturers.
