Binding text

CONCEPTUAL HEALTHCARE CORPORATION PATENT NON-ASSERTION PLEDGE — VERSION 1.0

Effective Date: April 1, 2026.
Pledger: Conceptual Healthcare Corporation, a Florida corporation, and its successors and assigns (collectively, "CHC").
Pledged Patents: U.S. Provisional Patent Application No. 63/921,717 ("the Master Equation Application"), any patent issued therefrom or claiming priority thereto, and any continuation, divisional, continuation-in-part, reissue, reexamination, or foreign counterpart of any of the foregoing (collectively, "Pledged Patents").

1. Pledge. CHC, on behalf of itself and its successors and assigns, hereby covenants not to assert any claim of infringement under any Pledged Patent against any Permitted User in connection with any Permitted Use.

2. Permitted Users. The following persons and entities are Permitted Users:
  (a) any individual licensed to practice medicine, nursing, pharmacy, dentistry, psychology, social work, or any allied health profession in any jurisdiction, when acting in that licensed capacity;
  (b) any institution of higher education, public health agency, or non-profit research organization, including individuals working under their auspices;
  (c) any developer or distributor of software released under a license approved by the Open Source Initiative;
  (d) any Federally Qualified Health Center, Rural Health Clinic, free clinic, religious clinic, or hospital qualifying under Section 501(r) of the Internal Revenue Code, when providing services on a non-commercial basis;
  (e) any individual using a Pledged Patent to score, track, or reason about their own health or that of their immediate family; and
  (f) any national, sub-national, or supra-national public health authority operating a public health program in which the program is provided at no direct cost to the patient.

3. Permitted Use. Permitted Use means any use of the claimed invention(s) of any Pledged Patent in connection with the activities listed in Section 2 above, including teaching, publishing, reducing to practice, deploying, modifying, and distributing.

4. Defensive carve-out. The Pledge does not extend, and CHC reserves all rights, against any person or entity that, on or after the Effective Date, asserts any patent claim against CHC, an Affiliate of CHC, a Permitted User, or any product or service of CHC. The Pledge is automatically reinstated to such person or entity upon a final, non-appealable dismissal of all such claims with prejudice.

5. Successor binding. If CHC assigns, transfers, or otherwise conveys any Pledged Patent, CHC shall require, as a condition precedent to the conveyance, that the assignee or transferee agree in writing to be bound by this Pledge. The text of this Pledge is incorporated by reference into the corporate charter of CHC.

6. Irrevocability. This Pledge is irrevocable. CHC may publish later versions that broaden the Pledge but may not narrow it. Any inconsistency between a later version and this Version 1.0 is to be resolved in favor of the broader scope.

7. No warranty; no other rights. The Pledged Patents are pledged on an "as is" basis. Nothing in this Pledge grants any trademark, copyright, trade secret, or other intellectual property right; conveys any warranty, express or implied; or relieves any Permitted User of regulatory obligations under applicable law (including, in the United States, FDA Software-as-a-Medical-Device requirements).

8. Governing law. This Pledge is governed by the laws of the State of Florida, U.S.A., without regard to conflicts of law principles. Any third-party beneficiary of this Pledge may enforce it directly.

9. Verification. The current text of this Pledge is published at /legal/patent-pledge.html on conceptualhealth.com and at the equivalent path on coin.health, conceptualhealthcare.com, and conceptualhealthcare.org. The cryptographic hash of the canonical version is anchored to CH Chain at the Effective Date.

What this does not do

This Pledge does not give a commercial competitor — a for-profit insurer, a for-profit hospital chain operating profitably, a wellness app charging consumers, an HMO — a free pass to embed our equation in their paid product. Those parties can license, on commercially reasonable terms, by emailing patents@conceptualhealth.com. The Pledge is a floor; we welcome more commercial licensees, not fewer.
