Interoperability Principles Patent Maps
To assist in determining whether a patent license may be beneficial, Microsoft provides the following lists of protocols documented pursuant to the Interoperability Principles that are covered by one or more Microsoft patents or patent applications. Microsoft will not assert any patents on such protocols unless patent (or patent applications) coverage is indicated on the lists provided below. These lists are made available once for each release of a high-volume product that includes such protocols.
Microsoft makes a separate
covenant not to sue open source developers for development and non-commercial distribution of implementations of certain protocols.
