Legal · Patent Non-Assertion Pledge

Patent Non-Assertion Pledge.

A patent should defend a body of work, not block one. This is the binding text of what Conceptual Healthcare Corporation promises it will never sue over with respect to U.S. Provisional Patent Application 63/921,717 — the Master Equation patent — and every patent issuing from it. Read it. Quote it. Hold us to it. Version 1.0 · Effective 1 April 2026.

1 · The promise, in plain English

Six classes of user. Will never be sued.

Conceptual Healthcare Corporation will not assert the Master Equation patent — U.S. Provisional 63/921,717, the patents that issue from it, and their continuations, divisionals, continuation-in-parts, reissues, reexaminations, and foreign counterparts (the "Pledged Patents") — against:

  1. Any clinician using the equation in the practice of medicine.
  2. Any researcher using the equation in academic, public-health, or non-commercial research.
  3. Any open-source implementation released under an OSI-approved license (including derivatives).
  4. Any safety-net provider — FQHC, free clinic, religious clinic, charitable hospital under §501(r) — operating non-commercially.
  5. Any patient using the equation to score their own life, by any means.
  6. Any nation-state public health agency using the equation in a national or sub-national public-health program at no charge to the patient.

2 · Binding text

The legal instrument. Read it as written.

"Conceptual Healthcare Corporation, a Florida corporation, hereby grants an irrevocable, royalty-free, worldwide, non-exclusive covenant not to sue ("Pledge") to each Permitted User (as defined above) with respect to the Pledged Patents.

The Pledge runs with the Pledged Patents and binds Conceptual Healthcare Corporation, its affiliates, and any successor or assignee. Any assignee of the Pledged Patents must agree in writing to be bound by this Pledge as a condition of the assignment.

This Pledge is irrevocable. Any revised version of this Pledge published at /legal/patent-pledge/ may only broaden the rights granted herein. Narrowing amendments are void.

Defensive carve-out. The Pledge does not extend to any party that asserts a patent claim against Conceptual Healthcare Corporation, an affiliate, a Permitted User, or any product or service of Conceptual Healthcare Corporation. The Pledge is automatically reinstated to such a party upon final dismissal of the asserted claim with prejudice.

This Pledge is governed by the laws of the State of Florida, without regard to conflicts of laws principles."

3 · What this does not do

Read this list before relying on the Pledge.

This Pledge does not: grant any warranty, express or implied; grant any right under trademark, copyright, or trade-secret law; relieve any party of regulatory obligations (FDA SaMD posture, HIPAA, GDPR, state medical practice acts, FDA Quality System Regulation, etc.); or grant rights to commercial users outside the six Permitted User classes above.

Commercial users not covered by the Pledge — for-profit insurers, hospital chains, wellness apps, HMOs — may license the Pledged Patents on commercially reasonable, non-discriminatory terms. Contact patents@conceptualhealth.com for licensing inquiries.
