IBM wants to encourage broad adoption of the Covered Specifications listed below. Therefore, IBM irrevocably covenants to you that it will not assert any Necessary Claims1 against you for your making, using, importing, selling, or offering for sale Covered Implementations2. However, this covenant will become void, and IBM reserves the right to assert its Necessary Claims against you, if you (or anyone acting in concert with you) assert any Necessary Claims against any Covered Implementations of IBM or of any third party. This covenant is available to everyone directly from IBM, and does not flow from you to your suppliers, business partners, distributors, customers or others. So, if your supplier, business partner, distributor, customer or other party independently takes an action that voids the covenant as to itself, IBM reserves the right to assert its Necessary Claims against that party, even though this covenant will remain in effect for you.

By making this irrevocable patent covenant with regard to the Specifications listed below, IBM does not represent that it holds any or all Necessary Claims regarding the Open Specifications you choose to implement.

Reference to IBM (or you) includes entities controlled by, controlling, and under common control with IBM (or you), based on majority control.
