Definition
In patent law, any mechanical device or combination of mechanical powers and devices arranged to perform a function and produce a certain effect or result. A machine is one of the four statutory categories of patentable subject matter, alongside processes, manufactures, and compositions of matter. More precisely, a machine is a concrete thing consisting of parts or devices in combination. What distinguishes one machine from another is its principle — that is, its mode of operation, or the particular combination of devices that sets it apart from other machines. A machine need not be complex; even a simple arrangement of mechanical elements qualifies if it directs force or motion toward a functional result. The term is used almost exclusively in its patent law sense within the legal dictionaries. Outside patent law, "machine" appears occasionally in regulatory, tax, and commercial contexts to describe physical apparatus used in manufacturing or production, but those usages track the ordinary meaning rather than a distinct legal definition.
Common Language
Modern common usage (Wiktionary): A device that directs and controls energy, often in the form of movement or electricity, to produce a certain effect; also extended colloquially to vehicles, computers, answering machines, and highly efficient persons or organizations. Historical common usage (Webster's 1913): Any combination of bodies so connected that their relative motions are constrained, and by means of which force and motion may be transmitted and modified — especially a construction consisting of a combination of moving parts or simple mechanical elements. The legal definition in patent law is narrower than the modern colloquial sense in one important respect: a "computer" or software-implemented process is not automatically a machine simply because a computer is colloquially called one. Whether a software or computer-implemented invention qualifies as a machine under patent law has been a persistent and contested question, and researchers should not assume the common meaning resolves it.
Common Confusion
Machine vs. Process vs. Manufacture: The four statutory patent categories overlap at the edges, and courts have long struggled to classify inventions that combine elements of more than one. A machine produces a result through physical structure and moving parts; a process achieves a result through a series of steps. An invention can simultaneously embody both. Researchers encountering historical patent disputes should not assume the classification was obvious or settled — characterization of the invention often determined validity and scope of protection. Machine vs. Principle: The historical dictionaries are careful to distinguish a machine from the principle underlying it. A patent on a machine does not monopolize the abstract principle or mode of operation in the abstract — only the concrete embodiment. This distinction shaped early American patent doctrine and remains a live issue in software and AI patent litigation.
Why It Matters in Research
The primary research context for this term is patent law, and the core navigational challenge is chronological instability. The word "machine" in nineteenth-century patent sources carries a narrower mechanical meaning than modern usage invites. Researchers working in the Law Mind corpus across historical periods should expect: Definitional compression in early sources. Black's both editions and Anderson's define machine almost identically, drawing on the same line of patent case law. The definitions reflect a world of physical gears, levers, and pulleys. Bouvier simply redirects to the PATENT entry, which is itself a signal that the term's legal content was understood to be patent-specific and corpus-bound. The "mode of operation" test. Anderson's articulation — that the principle of a machine is its mode of operation — is the key phrase for researching how courts distinguished infringing machines from non-infringing ones. Two machines may look different but share the same mode of operation, making them legally equivalent for infringement purposes. This principle is foundational to claim construction research. Software and computer-implemented inventions. None of the historical dictionaries anticipate this problem, but researchers using this term as an entry point into modern patent doctrine will quickly encounter it. The question of whether software running on a computer constitutes a "machine" under the patent statute was the central battleground of late twentieth and early twenty-first century patent eligibility law. The historical dictionary definitions are essentially silent on this, making them misleading if applied uncritically to modern materials. Regulatory and commercial contexts. Outside patent law, "machine" appears in industrial and labor regulations, equipment financing, and tax depreciation schedules. In those contexts the term is not a term of art — it carries its ordinary meaning and researchers should treat it accordingly.
Historical Dictionary Support
The four source dictionaries present a notably unified picture, which itself is informative. Black's first and second editions reproduce nearly identical language, suggesting the definition was considered settled by the turn of the twentieth century and drawn from a stable line of federal patent decisions. Anderson's adds the "mode of operation" language that gives the definition practical texture — it tells researchers not just what a machine is but what distinguishes one machine from another. Bouvier's bare cross-reference to PATENT reflects a different editorial judgment: that "machine" has no independent legal content separable from the patent law framework in which it operates. What the historical dictionaries miss collectively is significant. They do not address: (1) the boundary between machine and process for combination inventions; (2) the relationship between machine patents and functional claiming; or (3) any non-patent legal usage. Researchers should treat these entries as a foundation for patent law research circa 1900, not as a comprehensive account of the term's legal life.
Jurisdictional Note
In the United States, "machine" as a patent category is defined by federal statute and interpreted exclusively by federal courts, with the Court of Appeals for the Federal Circuit holding primary appellate jurisdiction. There is no meaningful state-law variation on the patent definition. Researchers working in non-U.S. patent systems should be aware that the statutory categories differ — "machine" is a U.S. Patent Act term of art and does not map directly onto patent categories in other major systems.

Black's Law Dictionary • 1891
In patent law. Any con- trivance used to regulate or augment force or motion; more properly, a complex struct- ure, consisting of a combination, or peculiar modification, of the mechanical powers. The term "machine," in patent law, includes every mechanical device, or combination of me chanical powers and devices, to perform some func- tion and produce a certain effect or result. But where the result or effect is produced by chemical action, by the operation or application of some ele- ment or power of nature, or of one substance to another, such modes, methods, or operations are called "processes. ກ A new process is usually the result of discovery; a machine, of invention. 15 How. 252, 267.

Anderson's Dictionary of Law • 1890
In the law of patents, includes every mechanical device, or combination of mechanical powers and devices, to perform some function and produce a certain effect or result.4 A concrete thing, consisting of parts or of certain devices and combination of devices. The principle of a machine is "its mode of operation," or that peculiar combination of devices which distinguishes it from other machines. A mere principle or idea cannot constitute a machine.5 Patentable inventions pertaining to machines are: 1. Entire machines; as, a car for a railroad, a sewing-machine. 2. Separate devices of a machine; as, the coulter of a plow, the driver of a reaping-machine. 3. New devices of a machine in combination with old elements, all embraced in one claim, or with separate claims for what is new, together with a claim for the new combination of all the elements. 4. Devices or elements of a machine in combination, all being old. All that the law requires of an inventor of a machine is that he shall describe the manner of constructing 1 Exp. Wall. 107 U.

Under these provisions, it has been held that a patentee is not generally limited to the literal import of his description of his invention, but that, in construction, he may make such modifications of it as do not involve a departure from its principle or a material change in its mode of operation. See EQUIVALENT, 2; MODE, Of operation; PATENT, 2; PROCESS, 2. Machinery. Means somewhat more than machine. Includes whatever is necessary to the working of a machine; as, dies used in manufacturing tinware, the saw in a sawmill, the pipes of a gas company.2 When cars, though used at times, and at other times detached, are formed into a train, to which propelling force is imparted by means of a locomotive, the entire train constitutes machinery connected with or used in the particular business. In determining whether machinery becomes a fixture, regard must be had to the object, and to the effect and mode, of annexation.4 See FIXTURE. An employee who knows that machinery which he is operating is so defective as to be dangerous, protests against further use of it, receives no assurance that the defect will be remedied, but continues to use it, voluntarily assumes the incidental risks.
