This file names the third-party frameworks referenced anywhere in this repository, states this project's non-affiliation with each rights-holder, and defines the exact attribution pointer string that every framework-touching file in this repository must carry.
LICENSE governs copyright in this repository's original content, and this file, NOTICES.md,
governs trademark and attribution. The two files touch without overlapping, and neither should
be read as covering the other's territory.
The MIT grant in LICENSE conveys copyright permissions in this repository's original content
only. It grants no rights in any third-party trademark, service mark, or trade name, and none of
the framework names below are licensed by that grant.
All content in this repository is MIT-licensed unless a file states otherwise. This repository
uses one root LICENSE file rather than per-file copyright headers, so a file carrying no header
of its own is covered by the root license, not left undefined.
The framework statements below ship before any framework-derived content exists anywhere in this repository, because a notice that arrives after the content it covers has already failed.
The following string is the canonical, verbatim attribution pointer. A human contributor and
tools/check_repo.py both read this fenced block as the single source of truth for the string;
neither restates it from memory.
Concepts here are paraphrased from publicly described sales frameworks. Not affiliated with or endorsed by any framework rights-holder. See NOTICES.md.

A listed path that does not exist yet is skipped by the checker. A listed path that does exist must carry the string above exactly once.
The three statements below appear in a fixed order, and each carries the same four labelled elements in the same order, so a future diff to this section shows a content change and never a reordering.
Mark: Command of the Message
Rights-holder: Force Management, which uses the mark in its own name on its own public pages. No change of holder was found when this statement was last reviewed.
Non-affiliation: This project is not affiliated with, endorsed by, sponsored by, or connected to Force Management.
Paraphrase boundary: This repository restates concepts associated with Command of the Message in its own words and reproduces no training material, no course content, and no proprietary diagram belonging to Force Management.

Mark: MEDDIC, MEDDICC, MEDDPICC, and related marks in this family.
Rights-holder: Ownership of these marks is claimed by multiple parties and is contested; this file does not attribute them to a single holder. This repository makes no claim about the validity of any mark in this family and no claim about the outcome of any proceeding, and a determination about one spelling in the family is not treated here as covering another.
Recorded as public record, observed on the review date below. In MEDDICC Ltd. v. 01 Consulting LLC, No. 2:24-cv-01836 (E.D. Pa.), before Chief Judge Wendy Beetlestone and filed 2024-04-30, the court granted summary judgment on 2026-04-21, holding MEDDPICC generic, dismissing the counterclaims with prejudice, and directing the USPTO to cancel Registration No. 6,489,058, held by Darius Lahoutifard of 01 Consulting LLC. On the review date that docket carried no termination date and its most recent entry was dated 2026-09-14, and the USPTO register still recorded Registration No. 6,489,058 as live. These are facts about a proceeding, not a position in it: the two sentences above stand unchanged, the proceeding reached one registration of one spelling, and nothing here is a prediction of where it ends.
Non-affiliation: This project is not affiliated with, endorsed by, or sponsored by any party claiming rights in these marks.
Paraphrase boundary: This repository restates concepts associated with this family of marks in its own words and reproduces no training material, no course content, and no proprietary diagram belonging to any claimant.

Mark: Challenger (the Challenger Sale methodology).
Rights-holder: The Challenger business and its trademark successors. On the review date below the Challenger site was operating under the corporate name Challenger Performance Optimization, Inc. and identifying itself as part of Richardson Sales Performance, which announced its acquisition of Challenger in September 2024. The successor clause is retained deliberately, so this statement stays true through the next change of hands rather than having to be corrected after it.
Non-affiliation: This project is not affiliated with, endorsed by, sponsored by, or connected to Challenger Inc. or its trademark successors.
Paraphrase boundary: This repository restates concepts associated with Challenger in its own words and reproduces no training material, no course content, and no proprietary diagram belonging to Challenger Inc. or its trademark successors.

None of the three statements above positions this project as a version, an implementation, an edition, or an automation of the named framework: each states only that concepts associated with the mark are paraphrased here, in this repository's own words, with no more use of the mark than is needed to identify what the concepts derive from.
