Dear All, as promised, below is an example of a non-assertion covenant statement that may be used in the Licensing information section of the IETF's IPR Disclosure form: If any claim of any patent owned or controlled by XXX or its Affiliates is essential on a technical ground to the standard adopted by IETF, XXX on behalf of itself and its Affiliates hereby covenant not to assert any such claim against any party for making, using, selling, offering for sale or importing a product that implements the corresponding part of the standard. However, nothing herein shall preclude XXX or any of its Affiliates from asserting the above-mentioned patent claims against any party that asserts directly or indirectly a patent it owns or controls against XXX and/or its Affiliates, or against any products of XXX or its Affiliates either alone or in combination with other products. FRAND royalty-bearing licenses will be available to anyone who prefers that option. Of course, you can find more examples among many of the IPR Disclosures that use the covenant licensing terms in their IPR Dislosures.
Hope this will be helpful. Regards, Greg
