A. For granted patents or published pending patent applications, please provide the following information:

Patent, Serial, Publication, Registration, or Application/File number(s)

Number: WO2026172333,WO2026150381

Title: PRIVACY PRESERVING ANTI-HARASSMENT AND SPAM-FREE COMMUNICATION FOR MAP-BASED BUSINESS DISCOVERY AND AI NATIVE TELECOMMUNICATION USING QUERY-SCOPED COMMUNICATION HANDLES
Date: 2026-07-01
Notes: IETF / Standards Licensing Position

Any FRAND commitment made by me in connection with an IETF disclosure is strictly limited to those specific patent claims that become necessary for implementation of a specification actually adopted or standardised by the IETF, and that fall within the applicable definition of Necessary Patent Claims under the relevant IETF IPR rules.

For clarity, I am not offering all claims contained in the disclosed patent applications, related PCT applications, priority applications, or broader patent portfolio on FRAND terms merely because those applications are disclosed to the IETF or because some technical concepts contained in them are discussed, referenced, or considered during the standards process.

Only the specific claims that are actually necessary to implement the relevant adopted IETF specification are intended to fall within the FRAND commitment.

All other claims remain outside that commitment. This includes claims relating to non-standardised embodiments, alternative implementations, optional functionality, other industries, other technical environments, proprietary implementations, broader architectural concepts, or subject matter that is not necessary for compliance with the relevant adopted IETF specification.

Accordingly, the FRAND commitment should be understood as applying only to the minimum set of Necessary Patent Claims required to implement the final adopted IETF specification, and not to an entire patent application, patent family, PCT filing, or portfolio as a whole.

For those specific Necessary Patent Claims, I am willing to make licences available on fair, reasonable and non-discriminatory terms, including a possible reasonable royalty or fee where permitted and applicable under the relevant IETF licensing declaration and policies.

B. Does this disclosure relate to an unpublished pending patent application?:

Has patent pending No

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 Reasonable and Non-Discriminatory License to All Implementers with Possible Royalty/Fee
Licensing information, comments, notes, or URL for further information

My primary motivation in filing this work has not been financial gain. I filed it because I wanted the technical ideas, architecture, and development effort to be formally recorded and attributable, in the hope that the work may one day form part of the historical record alongside other meaningful inventions and inventors.

I have undertaken this work as an independent inventor, without an external technical team, without external funding, and with limited personal financial resources. The filing costs have been paid from my own personal savings. I do not presently have sufficient financial resources to pursue every possible national-phase filing, prosecution pathway, or jurisdiction in which protection might otherwise be desirable.

I was fully aware of this financial limitation before filing the PCT applications. I nevertheless chose to proceed because creating a formal, public, dated, and attributable technical record of the work was important to me. For the same financial reason, I intentionally handled the international-stage PCT filings without a patent attorney in order to conserve limited resources for filing fees, publication, prosecution, and possible national-phase entry.

Commercial licensing opportunities would of course be welcome, but financial return has not been the sole or primary reason for making these filings. Recognition of the technical contribution, preservation of the development record, and the possibility that the architecture may contribute to future technologies, public infrastructure, safety systems, and technical standards are also important objectives.

Voluntary Royalty-Free Public-Interest Licensing Position

Separately, and entirely as a voluntary public-interest commitment, I am willing to consider granting royalty-free licences to sovereign governments and public authorities for strictly non-commercial public-interest uses, including public safety, emergency response, disaster management, child safety, critical-infrastructure protection, and similar genuine governmental or public-interest purposes.

This voluntary position does not itself grant any licence and should not be interpreted as an automatic, unconditional, irrevocable, or generally available royalty-free licence.

Any royalty-free permission would arise only through a separate written licensing agreement entered into with the relevant sovereign government or public authority. That written agreement may define the relevant patent rights, technology, project, permitted purpose, duration, territory, safeguards, beneficiaries, and scope of use.

Such a voluntary royalty-free arrangement would not automatically extend to commercial exploitation, commercial resale, sublicensing, unrelated private-sector use, or contractors using the technology outside the expressly authorised governmental or public-interest purpose.

This voluntary sovereign and public-interest licensing policy is separate from the IETF FRAND commitment and does not modify the licensing terms applicable to ordinary implementers of an IETF specification.

Nothing in this statement is intended to constitute a general patent waiver, abandonment of patent rights, dedication of the portfolio to the public, unrestricted royalty-free licensing, or a FRAND commitment covering claims that are not Necessary Patent Claims for the relevant adopted IETF specification.

My broader objective remains to establish and preserve an attributable technical record of the work, obtain appropriate recognition for the contribution, and, where possible, allow the technology to contribute constructively to future standards, sovereign infrastructure, public safety, and technological development.

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.
