Microsoft gets $5 for every HTC phone running Android, according to Citi analyst Walter Pritchard, who released a big report on Microsoft this morning. Microsoft is getting that money thanks to a patent settlement with HTC over intellectual property infringement. Microsoft is suing other Android phone makers, and it’s looking for $7.50 to $12.50 per device, says Pritchard.

HTC Pays Microsoft $5 Per Android Phone, Says Citi.

A rough estimate of the number of HTC Android devices shipped is 30 million. If HTC paid $5 per unit to Microsoft, that adds up to $150 million Android revenues for Microsoft.

Microsoft has admitted selling 2 million Windows Phone licenses (though not devices.) Estimating that the license fee is $15/WP phone, that makes Windows Phone revenues to date $30 million.

So Microsoft has received five times more income from Android than from Windows Phone.

Looking forward and assuming that Microsoft can receive this type of settlement from about half of the Android license takers, then the prospects of a windfall from Android dwarf the expected income from Windows Phone.

Google’s Android seems the best thing that could have happened to Microsoft’s mobile efforts, ever.

I could also calculate how the Android license income could be further funneled to Nokia (via their current agreement with Microsoft) for promotion of its phones. Thus, an Android licensee could reduce his margins in order to promote a competitor’s products.
