Microsoft has outlined a new intellectual-property policy for co-developed technology that embraces open source and seeks to assure customers it won’t run off with their innovations.

The shared innovation principles build on its Azure IP Advantage program for helping customers combat patent trolls.

The new principles for co-developed innovation cover ownership of existing technology, customer ownership of new patents, support for open source, licensing new IP back to Microsoft, software portability, transparency, and learning.

Microsoft has pretty much made a living out of licensing I am not surprised they want to do this still.
