Microsoft Community Promise

Published: September 12, 2007 | Revised: January 31, 2023

Microsoft irrevocably promises not to assert any Microsoft Necessary Claims against you for making, using, selling, offering for sale, importing or distributing any implementation, to the extent it conforms to one of the Covered Specifications, and is compliant with all of the required parts of the mandatory provisions of that specification ("Covered Implementation"), subject to the following:

This is a personal promise directly from Microsoft to you, and you acknowledge as a condition of benefiting from it that no Microsoft rights are received from suppliers, distributors, or otherwise in connection with this promise. If you file, maintain, or voluntarily participate in a patent infringement lawsuit against a Microsoft implementation of any Covered Specification, then this personal promise does not apply with respect to any Covered Implementation made or used by you. To clarify, "Microsoft Necessary Claims" are those claims of Microsoft-owned or Microsoft-controlled patents that are necessary to implement the required portions (which also include the required elements of optional portions) of the Covered Specification that are described in detail and not those merely referenced in the Covered Specification.

This promise by Microsoft is not an assurance that either (i) any of Microsoft issued patent claims covers a Covered Implementation or are enforceable, or (ii) a Covered Implementation would not infringe patents or other intellectual property rights of any third party. No other rights except those expressly stated in this promise shall be deemed granted, waived or received by implication, exhaustion, estoppel, or otherwise.
