V. Licensing Declaration

The Patent Holder states that its position with respect to licensing any patent claims contained in the patent(s) or patent application(s) disclosed above that would necessarily be infringed by implementation of the technology required by the relevant IETF specification ("Necessary Patent Claims"), for the purpose of implementing such specification, is as follows(select one licensing declaration option only):

Licensing See Text Below for Licensing Declaration
Licensing information, comments, notes, or URL for further information

The IETF Transport Layer Security (“TLS”) 1.3 Specification, involving cryptography, is significant for the industry. As IETF considers the next version(s) of the standard, IBM hereby discloses two patented inventions that would greatly improve TLS in multiple ways. These inventions should contribute significantly to internet security.
IBM encourages broad adoption and high performance of the Covered Specifications. Therefore, in that, historically, beneficial patented technologies (of others) have been excluded or deleted from IETF standards when royalties are involved, IBM irrevocably covenants, to you, subject to conditions outlined below, that it will not assert any of the identified patents, to the extent they include Necessary Claims, against you for your making, using, importing, selling, or offering for sale Covered Implementations. 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 or on your behalf) assert any Necessary Claims against any Covered Implementations of IBM. This covenant is available to everyone directly from IBM, and, to the extent permitted by law, 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 agrees to no other obligations or representations.
Covered Specifications:
"Necessary Claims" are those claims of the patents listed below that cannot be avoided by any commercially reasonable, compliant implementation of the Required Portions of a Covered Specification. "Required Portions" are those portions of a Covered Specification that must be implemented to comply with such Specification. If the Specification prescribes discretionary extensions, Required Portions include those portions of the discretionary extensions that must be implemented to comply with such discretionary extensions.
"Covered Implementations" are those specific portions of a product (hardware, software, services or combinations thereof) that implement and comply with a Covered Specification and are for inclusion in a fully compliant implementation of that Covered Specification. Reference to IBM (or you) includes entities controlled by, controlling, and under common control with IBM (or you), based on majority control.

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.
