Abstract
H-NARE 2.0 is a hybrid numeric-alphabetic indexing and invention-development method for large, multi-domain open-hardware portfolios. It gives each disclosure a stable numeric identifier, assigns it to one or more engineering domains, records its development status, and links related inventions, upgraded versions, shared components, and research platforms.
The method addresses a practical problem: when an inventor or research group publishes hundreds of related disclosures, readers, collaborators, and AI-assisted research tools need a reliable way to locate relevant prior disclosures, distinguish new work from corrected or upgraded versions, and identify which existing inventions can be combined into a new system.
H-NARE 2.0 also describes a repeatable workflow in which prior disclosures are used as modular engineering inputs for new inventions and for upgrades to earlier inventions. The Caldwell open-hardware portfolio is included as a worked example, not as a claim of commercial performance or adoption.
