Microsoft is demanding that Korean mobile maker Samsung hands over $15 for every Android-powered handset it sells.
The software giant says that the open source Android operating system contains a wide range of its own patents and, as such, it is entitled to a substantial slice of any profits made.
The Redmond-based software monopolist has a precedent to follow after it struck a similar deal with Taiwanese outfit HTC last year. HTC also uses the Google-owned mobile OS.
According to a Reuters report, the licensing deal could be reduced to $10 per unit if Samsung agrees to bung the Windows 7 Mobile OS on more of its hardware.
Although not mentioned by the report, the deal would almost certainly cover Samsung's Android-powered tablet devices as well.
