Microsoft Open Specification Promise

The Microsoft Open Specification Promise (English Microsoft promises of open specifications ) describes a promise by the company Microsoft to refrain regarding 35 patented web services to the enforcement of its patents for non- commercial use.

Up to the time of the promise Microsoft made its patent rights not enforced, but this option was always open to the developers and users by then. Microsoft also omitted on the crediting of Microsoft technologies. The Microsoft Open Specification Promise is compatible with free and open source licenses in parts. The extent to which this promise, however, has legal validity until now has not been clarified. Lawrence Rosen, an advocate for open source software, analyzed ( according to American legal opinion ) the promise as concerns.

This move by Microsoft is viewed by some as a response to a growing acceptance of free software.
