Definition
Manufacture means the process of making or fabricating an article from raw or natural materials, whether by hand, machinery, or art, resulting in a product of new form, utility, or character distinct from the original materials. The term carries both a process meaning and a product meaning depending on context.
1. As a process: The act of transforming raw or natural substances into finished goods of practical use. The transformation required is meaningful — the resulting article must have a distinct character, form, or utility that the source materials lacked. Simple collection, extraction, or minimal processing typically does not qualify.
2. As a product: The finished article itself, as made from raw materials by hand, machine, or art.
3. In patent law: A statutory category of patentable subject matter. A "manufacture" in this sense is an article produced from raw or prepared materials by giving them new forms, qualities, properties, or combinations, whether by hand labor or machinery.
4. In criminal law: The production, preparation, compounding, or processing of a controlled substance, including any packaging or repackaging. Statutory definitions in drug contexts are typically broader than the common industrial meaning and may encompass activity at the smallest scale.
5. In products liability: The party that manufactures — the manufacturer — bears duties with respect to manufacturing defects, defined as deviations from an intended design that render a specific unit of a product unreasonably dangerous.
Common Language
Modern common usage (Wiktionary): The action or process of making goods systematically or on a large scale; anything made, formed, or produced; a product.
Historical common usage (Webster's 1913): The operation of making wares or any products by hand, by machinery, or by other agency; anything made from raw materials by the hand, by machinery, or by art.
The common meaning emphasizes scale and systematic production — factory-style output. Legal usage, particularly in criminal drug statutes and patent law, does not require large scale or systematic operation. A single act of compounding a controlled substance may constitute manufacture under a criminal statute. Similarly, patent law's "manufacture" category covers articles produced in any quantity. Researchers should not import the common meaning's scale requirement into legal contexts.
Common Confusion
Manufacture vs. production vs. preparation: In controlled substance law, statutes often list manufacture, production, and preparation as separate or overlapping terms. Some jurisdictions define manufacture broadly enough to absorb the others; others treat them as distinct acts. A researcher working with drug statutes must read the specific statutory definition rather than assuming ordinary meaning controls.
Manufacture vs. assembly: Courts have sometimes distinguished manufacture — which transforms raw materials into something qualitatively new — from mere assembly of pre-made components. The distinction matters in patent law (whether a process is patentable) and in products liability (which entity in the supply chain qualifies as a manufacturer).
Core Elements
For a process to constitute manufacture in the classical legal sense, courts and commentators have looked to:
1. Input materials: Raw, natural, or prepared materials serving as the starting point.
2. Transformation: A meaningful change in form, character, quality, or utility — not mere packaging, sorting, or collection.
3. Output: A finished article suitable for use that would not otherwise exist in that form.
4. Agency: Hand labor, machinery, or art (skill and process). The mode of production does not determine whether the result is a manufacture.
In criminal drug contexts, statutory definitions typically replace this framework entirely. The statute's own definition governs.
Recognized Forms
/SUBTYPES
Manufacturing defect (products liability): A deviation in a specific unit of a product from the manufacturer's own design specifications, making that unit more dangerous than intended. Distinguished from design defects and warning defects.
Drug manufacture (criminal): Statutory manufacture of a controlled substance, defined broadly in federal law and most state codes to include production, preparation, propagation, compounding, or processing.
Manufacture as patent category: One of the four statutory categories of patentable subject matter alongside processes, machines, and compositions of matter.
Why It Matters in Research
The single word manufacture does different legal work depending on the body of law being researched. Researchers must identify which legal domain is implicated before relying on any general definition.
In patent research, the term "manufacture" has a long statutory lineage and courts have developed a specific — though contested — body of doctrine on what qualifies. Historical sources are relevant but the doctrine has evolved; older definitions may not reflect modern claim analysis.
In controlled substance research, the statutory definition in the applicable jurisdiction almost always overrides common law or common meaning. Federal and state definitions frequently differ. Some statutes define manufacture to include attempted or preparatory conduct. A researcher should locate and quote the governing statute directly rather than relying on dictionary definitions.
In products liability research, "manufacturer" as a legal actor and "manufacturing defect" as a legal theory are distinct concepts. A component part maker, a final assembler, and a brand-name seller may all carry manufacturer liability in some jurisdictions and not in others. The Law Mind encyclopedia entries on manufacturing defects and component part liability address these distinctions.
In older sources — particularly pre-twentieth-century cases and treatises — manufacture often appears in the context of patent disputes or industrial taxation. The meaning in those contexts closely tracks Bouvier and Burrill: transformation of raw materials into useful articles. Do not carry that narrow meaning into modern regulatory or criminal research.
Historical sources uniformly emphasize the transformation requirement. Anderson's formulation — that the article must become something "capable of being used in ordinary life" — was influential but is not a universal modern test. Cutting ice and storing it was held to be a manufacture in Louisiana courts cited by Bouvier; such examples illustrate that courts applied the concept broadly when economic and commercial activity was at stake.
Historical Dictionary Support
Burrill offers the most compact classical statement: manufacture is the process of making a thing by art, and the thing so made. His citation to Buller, J., in 2 H. Bl. 463 reflects the English common law inheritance of the term, where manufacture mattered chiefly for patent purposes under the Statute of Monopolies.
Bouvier expands this to include machinery alongside hand and art, and supplies concrete examples from American cases — fish lines, ropes, cordage, and ice cutting — demonstrating that courts applied the term broadly to industrial-era activity. His definition of the verb form ("to make or fabricate raw materials by hand, art, or machinery, and work into forms convenient for use") remains a serviceable baseline for non-statutory research.
Anderson adds the functional test: the article must have a new form capable of being used in ordinary life, and he acknowledges that the required process varies — sometimes it is the first transformation from natural state, sometimes a subsequent one. This flexibility is important for historical research because courts in different periods drew the transformation line differently based on the industry at issue.
Rapalje & Lawrence treat manufacture primarily as a term of art in patent law, directing the reader to the PATENT entry. This reflects the centrality of patent disputes to the legal meaning of manufacture through the nineteenth century.
None of the historical dictionaries address the criminal drug law meaning, which is a twentieth-century development. Researchers using these sources for controlled substance questions will find no applicable guidance.
Jurisdictional Note
In federal law, manufacture of a controlled substance is defined in the Controlled Substances Act and carries specific penalties that vary by substance and quantity. State drug manufacturing statutes follow varied formulations; some are narrower, some broader. In patent law, "manufacture" is a federal statutory category and federal doctrine controls uniformly. Products liability manufacturer status is a state law question with significant variation across jurisdictions.
