VIII. Other Notes

Additional notes

This disclosure relates to a United States provisional application filed under 35 U.S.C. 111(b). Provisional applications are not published, so no publication number exists. The application number, inventor, title and filing date in Section V(A) are given as they appear on the USPTO filing receipt for that application.

Certisyn additionally contemplates further applications covering subject matter in the document or documents identified in Section IV. They are within the scope of this disclosure because RFC 8179 Section 5.1.1 reaches intellectual property rights that may ultimately Cover the Contribution.

Certisyn will supplement this disclosure as the position changes.

Appendix C of draft-hillier-scitt-arp names compute-attestation reconciliation across heterogeneous trusted-execution and confidential-compute providers and places that specialisation outside the scope of the document. This disclosure is made because RFC 8179 Section 5.1.1 reaches intellectual property rights that may ultimately Cover a Contribution, and because Section 4.16 of the document specifies policy-version-hash sealing, which the disclosed application also claims. Certisyn makes the disclosure now so that the working group and implementers hold the position ahead of any revision or adoption decision that brings the specialisation into scope.

Only those sections of the relevant entry form where the submitter provided information are displayed above.
