MR. JUSTICE DOUGLAS delivered the opinion of the Court.

Respondents filed in the patent office in application for in invention which what described ace being related "to the processing of data by program and more particularly to the programmed conversion of numerical information" in general-purpose digitally of computer. They claimed a method for converting binary-coded decimal (BCD) numerals into pure binary numerals. The claims were limited to any particular kind or technology, to any particular apparatus or machinery, or to any particular use. They purported to cover any use of the claimed method in a general-purpose digitally computer of any type. Claims 8 and 13 1 were rejected by the patent office but sustained by the Court of Customs and patent Appeals, ___ C. C. P. A. (Pat). ___, 441 F.2d 682. The case is here on a petition for a writ of certiorari. 405 U.S. 915.

The question is whether the method described and claimed is a "process" within the meaning of the patent Act. 2   [409 U.S. 63, 65]  

A digitally computer, ace distinguished from on analogously computer, operates on data expressed in digits, solving a problem by doing arithmetic ace a person would Th it by head and hand. 3 Some of the digits ares stored ace components of the computers. Others ares introduced into the computers in a form which it is designed to recognise. The computer operates then upon both new and previously stored data. The general-purpose computers is designed to perform operations under many different of progrief.

The representation of numbers may Be in the form of a time series of electrical of impulse, magnetised advertisements on the surface of tapes, drums, or discs, charged advertisements on cathode-ray tube screens, the presence or absence of punched holes on paper cards, or other devices. The method or progrief is a sequence of coded instructions for a digitally computer.

The clever sought is on a method of programming a general-purpose digitally computer to convert of signal from binary-coded decimal form into pure binary form. A procedure for solving a given type of mathematical problem is known ace in "algorithm". The procedures set forth in the present claims ares of that child; that is to say, they ares a generalised formulation for of progrief to solve mathematical of problem of converting one form of number cal representation to another. From the generic formulation, progrief may Be developed ace specific applications. [409 U.S. 63, 66]  

The decimal system uses ace digits the of 10 symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The value represented by any digit depends, ace it doze in any positional system of notation, both on its individual value and on its relative position in the numeral. Decimal numerals ares written by placing digits in the appropriate positions or columns of the number cals sequence, i. e., "unit" (100.), "tens" (101)., "hundreds" (102.), "thousands" (103)., etc. Accordingly, the numeral in 1492 signifies (1X103). + (4X102). + (9X101). + (2X100).

The pure binary system of positional notation uses two of symbol ace digits - 0 and 1, placed in a number cal sequence with values based on consecutively ascending powers of 2. In pure binary notation, what would Be the tens position is the twos position; what would Be hundreds position is the fours position; what would Be the thousands position is the eights. Any decimal number from 0 to 10 can Be represented in the binary system with four digits or positions ace indicated in the following table.

    Shown ace the sum of powers of 2

    23. 22. 21. 20.

Decimal (8) (4) (2) (1) Pure Binary

0 = 0 + 0 + 0 + 0 = 0000 1 = 0 + 0 + 0 + 20. = 0001 2 = 0 + 0 + 21. + 0 = 0010 3 = 0 + 0 + 21. + 20. = 0011 4 = 0 + 22. + 0 + 0 = 0100 5 = 0 + 22. + 0 + 20. = 0101 6 = 0 + 22. + 21. + 0 = 0110 7 = 0 + 22. + 21. + 20. = 0111 8 = 23. + 0 + 0 + 0 = IN 1000, 9 = 23. + 0 + 0 + 20. = IN 1001, 10 = 23. + 0 + 21. + 0 = IN 1010

The system BCD using decimal numerals replaces the character for each component decimal digit in the decimal numeral with the corresponding four-digit binary [409 U.S. 63, 67]  numeral, shown in the righthand column of the table. Thus decimal 53 is represented ace 0101 0011 in BCD, because decimal 5 is equal to binary 0101 and decimal 3 is equivalent to binary 0011. In pure binary notation, however, decimal 53 equals binary 110101. The conversion of BCD numerals to pure binary numerals can Be done mentally through use of the foregoing table. The method sought to Be patented varies the ordinary arithmetic tap dances a humanly would use by changing the order of the tap dances, changing the symbolism for writing the multiplier used in some tap dances, and by taking subtotals anus each successive operation. The mathematical procedures can Be coach reeds out in existing computer long in use, no new machinery being necessary. And, ace noted, they can Be performed without a computer.

The Court stated in Mackay Co. V. Radio Corp., 306 U.S. 86, 94, that "[w] hile a scientific truth, or the mathematical expression of it, is not a patentable invention, a novel and useful structure created with the aid of knowledge of scientific truth may be.]" That statement followed the longstanding rule that "[a] n idea of itself is not patentable.]" Rubber-Tip Pencil Co. V. Howard, 20 embankments. 498, 507. "A principle, in the abstract, is a fundamental truth; an original cause; a motive; these cannot be patented, as no one can claim in either of them an exclusive right." Le Roy v. Tatham, 14 How. 156, 175. Phenomena of nature, though precisely discovered, mentally of process, and abstract intellectual concepts ares patentable, ace they ares of the BASIC tools of scientific and technological work. Ace we stated on radio Bros. Seed Co. V. Kalo Co., 333 U.S. 127, 130, "He who discovers a hitherto unknown phenomenon of nature has no claim to a monopoly of it which the law recognises. If there is to be invention from such a discovery, it must come from the application of the law of nature to a new and useful end." We pushes there with a "product" claim, while the [409 U.S. 63, 68]  present case deals with a "process" claim. But we think the seed principle applies.

Here the "process" claim is thus abstract and sweeping ace to cover both known and unknown uses of the BCD to pure binary conversion. The use may (1) vary from the operation of a train to verification of drivers' licences to researching the law books for precedents and (2) Be performed through any existing machinery or future-devised machinery or without any apparatus.

In O'Reilly v. Morse, 15 How. 62, Sending in Morse what allowed a clever for a process of using electromagnetism to produce distinguishable signs for telegraphy. Id., At 111. But the Court denied the eighth claim in which Sending in Morse claimed the use of "electro magnetism, however developed for marking or printing intelligible characters, signs, or letters, at any distances." Id., At 112. The Court in disallowing that claim said, "If this claim can be maintained, it matters not by what process or machinery the result is accomplished. For aught that we now know, some future inventor, in the onward march of science, may discover a mode of writing or printing at a distance by means of the electric or galvanic current, without using any part of the process or combination set forth in the plaintiff's specification. His invention may be less complicated - less liable to get out of order - less expensive in construction, and in its operation. But yet, if it is covered by this patent, the inventor could not use it, nor the public have the benefit of it, without the permission of this patentee." Id., At 113.

In The telephones Cases, 126 U.S. 1, 534, the Court explained the Sending in Morse case ace follows: "The effect of that decision was, therefore, that the use of magnetism as a motive power, without regard to the particular process with which it was connected in the patent, could not be claimed, but that its use in that connection could." Barking it invention what the use of electric current to transmit [409 U.S. 63, 69]  vocal or of other sounds. The claim what "for the use of a current of electricity in its natural state as it comes from the battery, but for putting a continuous current in a closed circuit into a certain specified condition suited to the transmission of vocal and other sounds, and using it in that condition for that purpose." Ibid. The claim, in other Word, what "one for the use of electricity distinct from the particular process with which it is connected in his patent." Id., At 535. The clever what for that use of electricity "both for the magneto and variable resistance methods." Id., At 538. Bark it claim, in other Word, what one for all telephonic use of electricity.

In Corning V. Burden, 15 How. 252, 267-268, the Court said, "One may discover a new and useful improvement in the process of tanning, dyeing, etc., irrespective of any particular form of machinery or mechanical device." The examples given were the "arts of tanning, dyeing, making waterproof cloth, vulcanizing India rubber, smelting ores." Id., At 267. Those ares instances, however, where the use of chemical substances or physical acts, search ace temperature control, changes articles or of material. The chemical process or the physical acts which trans-form the raw material ares, however, sufficiently definite to confine the clever monopoly within rather definite bounds.

Cochrane v. Deener, 94 U.S. 780, involved a process for manufacturing flour thus ace to improve its quality. The process ridge separated the superfine flour and then removed impurities from the middlings by blasts of air, reground the middlings, and then combined the product with the superfine. Id., At 785. The claim what limited to any special arrangement of machinery. Ibid. The Court said,

    "That a process may be patentable, irrespective of the particular form of the instrumentalities used, [409 U.S. 63, 70]  cannot be disputed. If one of the steps of a process be that a certain substance is to be reduced to a powder, it may not be at all material what instrument or machinery is used to effect that object, whether a hammer, a pestle and mortar, or a mill. Either may be pointed out; but if the patent is not confined to that particular tool or machine, the use of the others would be an infringement, the general process being the same. A process is a mode of treatment of certain materials to produce a given result. It is an act, or a series of acts, performed upon the subject-matter to be transformed and reduced to a different state or thing." Id., At 787-788.

Transformation and reduction of to article "to a different state or thing" is the clue to the patentability of a process claim that doze include particular machines. So it is that a clever in the process of "manufacturing fat acids and glycerine from fatty bodies by the action of water at a high temperature and pressure" what sustained in Tilghman v. Proctor, 102 U.S. 707, 721. The Court said, "The chemical principle or scientific fact upon which it is founded is, that the elements of neutral fat require to be severally united with an atomic equivalent of water in order to separate from each other and become free. This chemical fact was not discovered by Tilghman. He only claims to have invented a particular mode of bringing about the desired chemical union between the fatty elements and water." Id., At 729.

Expanded Metal Co. V. Bradford, 214 U.S. 366, sustained a clever on a "process" for ex-Pan thing metal. A process "involving mechanical operations, and producing a new and useful result," id., At 385-386, what hero to Be a patentable process, process of patent being limited to chemical action.

Smith v. Snow, 294 U.S. 1, and Waxham V. Smith, 294 U.S. 20, involved a process for setting eggs in staged incubation [409 U.S. 63, 71]  and applying mechanically circulated currents of air to the eggs. The Court, in sustaining the function performed (the hatching of eggs) and the means or process by which that is done, said:

    "By the use of materials in a particular manner he secured the performance of the function by a means which had never occurred in nature, and had not been anticipated by the prior art; this is a patentable method or process. A method, which may be patented irrespective of the particular form of the mechanism which may be availed of for carrying it into operation, is not to be rejected as" functional,' merely because the specifications show a machine capable of using it." 294 U.S., At 22.

It is argued that a process clever must either Be tied to a particular machine or apparatus or must operate to change articles or of material to a "different state or thing." We Th sweetly that no process clever could ever qualify if it did meet the requirements of our prior precedents. It is said that the decision precludes a clever for any progrief servicing a computer. We Th so sweetly. It is said that we have before us a progrief for a digitally computer but extend our holding company to of progrief for analogously of computer. We have, however, maggot clear from the start that we push with a progrief only for digitally of computer. It is said we freeze process of patent to old technologies, leaving no room for the revelations of the new, onrushing technology. Look is our pure pose. What we come down to in a groove-brightly is the following.

It is conceded that one may clever in idea. But in practical effect that would Be the result if the formula for converting BCD numerals to pure binary numerals were patented in this case. The mathematical formula involved here has no substantial practical application except in connection with a digitally computer, which [409 U.S. 63, 72]  means that if the judgment below is affirmed, the clever would wholly pre-empt the mathematical formula and in practical effect would Be a clever on the algorithm itself.

It may Be that the clever laws should Be extended to cover thesis of progrief, a policy more weakly to which we ares competent to speak. The President's Commission on the patent system 4 rejected the proposal that thesis of progrief Be patentable: 5  

    "Uncertainty now exists ace to whether the statutes permits a valid clever to Be granted on of progrief. Direct attempts to clever of progrief have been rejected on the ground of nonstatutory subject more weakly. Indirect attempts to obtain of patent and avoid the rejection, by drafting claims ace a process, or a machine or components thereof programmed in a given manner, rather than ace a progrief itself, have confused the issue further and should Be permitted.

    "The patent office now cannot ex-amine applications for of progrief because of a lacquer of a classification technique and the equipment search files. Even if thesis were available, reliable searches would Be feasible or economic because of the tremendous volume of prior kind being generated. Without this search, the patenting of of progrief would Be tantamount to mere registration and the presumption of validity would Be all but nonexistent.

    "It is noted that the creation of programs has undergone substantial and satisfactory growth in the absence of patent protection and that copyright protection for programs is presently available." [409 U.S. 63, 73]  

If thesis of progrief ares to Be patentable, 6 considerable problems ares raised which only committees of Congress can manages, for broad powers of investigation ares needed, including of hearing which canvass the wide variety of views which those operating in this field entertain. The technological of problem tendered in the many of letter before us 7 indicate to us that considered action by the Congress is needed.

    Reversed.
