RICH, Judge. Introduction These appeals are from decisions of the Board of Appeals (board) of the United States Patent and Trademark Office (PTO) under 35 U.S.C. § 141 by dissatisfied applicants for patents. We reverse. These two cases come before us for the second time under the circumstances hereinafter detailed. Since our first decisions, they have been to the United States Supreme Court and back without any decision by that Court. They are separate appeals, not formally consolidated, but on this second round they were heard together on November 6, 1978, • and are now decided together because, as will appear, they involve only the same single question of law. The question before us is a limited one of statutory construction, not whether appellants have made and disclosed patentable inventions. The PTO has already determined that both applicants are entitled to patents; in technical patent law terms, un-appealed claims to their respective inventions have been allowed to each'appellant and, whatever the final disposition of these appeals, patents will issue if the applicants choose to pay their fees and take them out. Thus, there is no question of this court having “extended the scope of the patent laws” as the Bergy petition for certiorari asserted (p. 6). Deciding, a case of first impression is not necessarily an “extension” of the law, it is a determination of what it means. The real question before us is whether appellants are to be allowed to define their inventions — already determined to be patentable — in a certain way in “claims” pursuant to 35 U.S.C. § 112, second paragraph. This question, which is the same in each case, involves the construction and application of 35 U.S.C. § 101, more particularly the meaning to be given to the words “manufacture” and “composition of matter” in that section, which reads: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. [Emphasis ours.] The PTO has raised no issue in either case, as to any aspect of the inventions, about compliance with the “conditions and requirements of this title,” that is to say the basic Title 35 requirements for patentability, which are utility, novelty, and nonobvi-ousness (35 U.S.C. §§ 101, 102, and 103), or any other statutory condition or requirement such as adequacy of disclosure (35 U.S.C. § 112, first paragraph). The sole issue, as the PTO chooses to view it, is whether an invention, otherwise patentable under the statute, is excluded from the categories of, subject matter which may be patented, set forth in § 101, because it is “alive.” As we shall show, the PTO does not appear to us to have been altogether consistent in its position on this question. First, however, we review the history of this litigation to show the posture of the cases as they are now before us again. Procedural Background In re Bergy, 563 F.2d 1031,195 USPQ 344 (Oust. & Pat.App.1977), vacated sub nom. Parker v. Bergy, 438 U.S. 902, 98 S.Ct. 3119, 57 L.Ed.2d 1145 (June 26, 1978), 198 USPQ 257 (1978), hereinafter “Bergy,” was decided by us October 6, 1977. We reversed a 2-to-l decision of the board, 197 USPQ 78 (Bd.App.1976), which affirmed the final rejection by the PTO examiner of claim 5 of Bergy’s application for patent serial No. 477,766, filed June 10, 1974. The real party in interest in Bergy is the assignee of the application, The Upjohn Company, Kalamazoo, Michigan. In re Chakrabarty, 571 F.2d 40, 197 USPQ 72 (Cust. & Pat.App.), cert. dismissed, - U.S. -, 99 S.Ct. 44, 58 L.Ed.2d 94 (1978), hereinafter “Chakrabarty,” was decided by us March 2, 1978. We reversed the decision of the board (unreported) which affirmed the final rejection by the PTO examiner of claims 7 — 9, 13, 15, 17, 21, and 24-26 of Chakrabarty’s application for patent serial No. 260,563, filed June 7, 1972. The real party in interest in Chakrabarty is the assignee of the application, General Electric Company. In the PTO, Chakrabarty was the first of the two cases to be decided, the decision of the board being dated May 20, 1976. An entirely different panel of the board decided Bergy on June 22, 1976, one member dissenting with an extensive opinion. A long passage of the Chakrabarty board opinion was copied verbatim by the Bergy board majority. Due to delay caused by a request for reconsideration in the PTO in Chakrabarty, the Bergy appeal was the first to reach this court. Having decided the sole question involved in Bergy, by our opinion dated October 6, 1977, wfien the identical question was presented to us in Chakrabarty in December of that year, we decided it on the basis of our Bergy decision as a controlling precedent in this court. Our opinion in Chakra-barty was published March 2, 1978. On April 20, 1978, a petition for a writ of certiorari in Bergy was filed in the Supreme Court by the Solicitor General on behalf of Lutrelle F. Parker, Acting Commissioner of Patents and Trademarks. The Court granted the petition June 26, 1978, and on the same day issued the following order: THIS CAUSE having been submitted on the petition for writ of certiorari and response thereto, ON CONSIDERATION WHEREOF, it is ordered and adjudged by this Court that the judgment of the United States Court of Customs and Patent Appeals in this cause is vacated; and that this cause is remanded to the United States Court of Customs and Patent Appeals for further consideration in light of Parker v. Flook, 437 U.S. 584 [98 S.Ct. 2522, 57 L.Ed.2d 451] (1978). [198 USPQ 193.] Parker v. Flook, 437 U.S. 584, 98 S.Ct. 2522, 57 L.Ed.2d 451, 198 USPQ 193 (1978), hereinafter “Flook ”, was a case from this court (In re Flook, 559 F.2d 21,195 USPQ 9 (Cust. & Pat.App.1977), reversed sub nom. Parker v. Flook, supra), involving a computerized method of updating alarm limits by application of a mathematical formula. It was decided by the Supreme Court, three Justices dissenting, on June 22, 1978, four days before the date of the foregoing order in Bergy. Meanwhile, in Chakrabarty, an extension of time to file a petition for a writ of certiorari requested by the Solicitor General had been granted by the Chief Justice on May 26,1978, extending the time to July 30, 1978. The petition, No. 78-145, was filed on July 26, 1978. August 3, 1978, the Commissioner of Patents and Trademarks, by his solicitor, petitioned this court to vacate its decision in Chakrabarty, recall its mandate, and enter a new decision affirming the PTO board in view of the Supreme Court’s order in Ber-gy. The solicitor argued that the action taken in Parker v. Flook showed that our decision in Chakrabarty “was demonstrably wrong.” Chakrabarty, on August 11, opposed the petition, pointing out that in the Supreme Court’s order in Bergy “there is no hint that this Court’s decisions in Bergy and Chakrabarty were ‘demonstrably wrong’.” We granted the petition to the extent of vacating our judgment. Perceiving the foregoing situation and being mindful of the similarities as well as the differences of the Bergy and Chakra-barty cases and of the fact they involved the same single issue, we issued orders in Bergy on August 8 and in Chakrabarty on August 11, 1978, restoring both cases to the calendar, setting times for filing supplementary briefs directed solely to the effect, if any, of Parker v. Flook on our decisions, and setting the cases for hearing together on November 6, 1978. Counsel for Chakrabarty and the Solicitor General then stipulated, pursuant to Rule 60(1) of the Supreme Court, that Chakra-barty’s petition for a writ of certiorari be dismissed in view of this court’s order vacating our judgment and recalling our mandate, and the petition was so dismissed on August 25, 1978. Prior to the oral argument, this court received amicus curiae briefs on behalf of The Regents of the University of California, The American Patent Law Association, Genentech, Inc. (a California Corporation located in South San Francisco), and Cornell D. Cornish, patent attorney, on behalf of himself and the Village of Belle Terre, Long Island, New York. The Genentech brief, furthermore, called to our attention three resolutions, Nos. 30-32, adopted by the Section of Patent, Trademark and Copyright Law of the American Bar Association at its August 1978 Annual meeting directed to the issue in these appeals and supportive of our prior decisions herein. (1978 Summary of Proceedings, Section of Patent, Trademark and Copyright Law, A.B.A. 31.) Appellants in both cases and the PTO appeared by counsel on November 6, 1978, and presented oral argument, whereupon the appeals were resubmitted for new decisions. Present Posture of the Cases Summarized In Bergy our judgment of October 6, 1977, was vacated by the Supreme Court on certiorari and we were directed to reconsider the case in the light of Flook. In Chak-rabarty, because the identical issue was involved, we vacated our own March 2, 1978, decision at the request of the PTO because it was obviously necessary to give it the same reconsideration. We therefore approach both cases with the slate wiped clean, having been “returned to square one,” to use a board game expression. Whatever we have to say in these cases is said here, though much of it was said before, and our prior opinions are to be deemed withdrawn. While certiorari was granted in Bergy, that case was returned to us without having been briefed or argued before the Supreme Court, on the very day that certiorari was granted, at the end of the Court’s term, and within four days of the decision in Flook, to be reconsidered by us in the light of the High Court’s opinion in Flook. The Court gave no intimation of what bearing it thought Flook has on the single issue in these appeals, except as it may be gleaned from the Flook opinion. Clearly, our assigned task is first to determine the bearing of Flook, if any, on these two appeals. This requires, as we see it, consideration not only of what was decided in Flook but examination of everything that was said in the opinion. Preliminary to that consideration, however, and laying the groundwork therefor, we will examine the Constitutional basis for the patent system and the anatomy of the statutes Congress has enacted insofar as they are relevant to the problem before us. The Constitution The grant of power to Congress to establish a patent system is in these familiar words of Article I, section 8, clauses 8 and 18: [The Congress shall have Power] * * [8] To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries; * * * [And] [18] To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers * *. Scholars who have studied this provision, its origins, and its subsequent history, have, from time to time, pointed out that it is really two grants of power rolled into one; first, to establish a copyright system and, second, to establish a patent system. See R. DeWolf, An Outline of Copyright Law 15 (1925); K. Lutz, Patents and Science. A Clarification of the Patent Clause of the Constitution, 18 Geo.Wash.L.Rev. 50 (1949); P. Federico, Commentary on the New Patent Act, 35 U.S.C.A. § 1 to § 110, 1, 3 (1954); G. Rich, Principles of Patentability, 28 Geo.Wash.L.Rev. 393 (1960). Their conclusions have been that the constitutionally-stated purpose of granting patent rights to inventors for their discoveries is the promotion of progress in the “useful Arts,” rather than in science. In enacting the 1952 Patent Act, both houses of Congress adopted in their reports this construction of the Constitution in identical words, as follows: The background, the balanced construction, and the usage current then and later, indicate that the constitutional provision is really two provisions merged into one. The purpose of the first provision is to promote the progress of science by securing for limited times to authors the exclusive right to their writings, the word “science” in this connection having the meaning of knowledge in general, which is one of its meanings today. The other provision is that Congress has the power to promote the progress of useful arts by securing for limited times to inventors the exclusive right to their discoveries. The first patent law and all patent laws up to a much later period were entitled “Acts to promote the progress of useful arts.” [H.R.Rep.No.1923, 82d Cong., 2d Sess. 4 (1952); S.Rep.No.1979, 82d Cong., 2d Sess. 3 (1952), U.S.Code Cong. & Admin.News 1952, pp. 2394, 2396. Emphasis ours.] It is to be observed that the Constitutional clause under consideration neither gave to nor preserved in inventors (or authors) any rights and set no standards for the patentability of individual inventions; it merely empowered Congress, if it elected to do so, to secure to inventors an “exclusive right” for an unstated “limited” time for the stated purpose of promoting useful arts. We have previously pointed out that the present day equivalent of the term “useful arts” employed by the Founding Fathers is “technological arts.” In re Musgrave, 431 F.2d 882, 893, 57 CCPA 1352, 1367, 167 USPQ 280, 289-90 (1970). See also In re Waldbaum, 457 F.2d 997, 59 CCPA 940, 173 USPQ 430 (1972) (Rich, J., concurring). We turn now to a consideration of how Congress has implemented the power delegated to it. Anatomy of the Patent Statute The reason for our consideration of the statutory scheme in relation to its Constitutional purpose is that we have been directed to review our prior decisions in the light of Flook and we find in Flook an unfortunate and apparently unconscious, though clear, commingling of distinct statutory provisions which are conceptually unrelated, namely, those pertaining to the categories of inventions in § 101 which may be patentable and to the conditions for patentability demanded by the statute for inventions within the statutory categories, particularly the nonob-viousness condition of § 103. The confusion creeps in through such phrases as “eligible for patent protection,” “patentable process,” “new and useful,” “inventive application,” “inventive concept,” and “patentable invention.” The last-mentioned term is perhaps one of the most difficult to deal with unless it is used exclusively with reference to an invention which complies with every condition of the patent statutes so that a valid patent may be issued on it. The problem of accurate, unambiguous expression is exacerbated by the fact that prior to the Patent Act of 1952 the words “invention,” “inventive,” and “invent” had distinct legal implications related to the concept of patentability which they have not had for the past quarter century. Prior to 1952, and for sometime thereafter, they were used by courts as imputing patentability. Statements in the older cases must be handled with care lest the terms used in their reasoning clash with the reformed terminology of the present statute; lack of meticulous care may lead to distorted legal conclusions. The transition made in 1952 was with respect to the old term “invention,” imputing patentability, which term was replaced by a new statutory provision, § 103, requiring nonobviousness, as is well explained and approved in Graham v. John Deere Co., supra n. 2. Part IV of that opinion, entitled “The 1952 Act,” quotes the key sections of the statute upon which patentability depends. Graham states that there are three explicit conditions, novelty, utility, and non-obviousness, which is true, but there is a fourth requirement, which alone, is involved here. This was also the sole requirement involved in Flook. The Revised Statutes of 1874, which contained the primary patent statutes revised and codified in 1952, lumped most of the conditions for patentability in a single section, § 4886, as did all of the prior statutes back to the first one of 1790. The 1952 Act divided that statute up into its logical components and added the nonobviousness requirement, which until then had been imposed only by court decisions. This attempt at a clearcut statement to replace what had been a hodgepodge of separate enactments resulted in a new and official Title 35 in the United States Code with three main divisions. Part I pertains to the establishment and organization of the PTO. Part II, here involved, covers patentability of inventions and the grant of patents. Part III relates to issued patents and the protection of the rights conferred by them. All of the statutory law relevant to the present cases is found in four of the five sections in Chapter 10, the first chapter of Part II: Sec. 100 Definitions Sec. 101 Inventions patentable [if they qualify] Sec. 102 Conditions for patentability; novelty and loss of right to patent Sec. 103 Conditions for patentability; non-obvious subject matter More strictly speaking, these cases involve only § 101, as did Flook. Achieving the ultimate goal of a patent under those statutory provisions involves, to use an analogy, having the separate keys to open in succession the three doors of sections 101,102, and 103, the last two guarding the public interest by assuring that patents are not granted which would take from the public that which it already enjoys (matters already within its knowledge whether in actual use or not) or potentially enjoys by reason of obviousness from knowledge which it already has. Inventors of patentable inventions, as a class, are those who bridge the chasm between the known and the obvious on the one side and that which promotes progress in useful arts or technology on the other. The first door which must be opened on the difficult path to patentability is § 101 (augmented by the § 100 definitions), quoted supra p. 956. The person approaching that door is an inventor, whether his invention is patentable or not. There is always an inventor;' being an inventor might be regarded as a preliminary legal requirement, for if he has not invented something, if he comes with something he knows was invented by someone else, he has no right even to approach the door. Thus, section 101 begins with the words “Whoever invents or discovers,” and since 1790 the patent statutes have always said substantially that. Being an inventor or having an invention, however, is no guarantee of opening even the first door. What kind of an invention or discovery is it? In dealing with the question of kind, as distinguished from the qualitative conditions which make the invention patentable, § 101 is broad and general; its language is: “any * * * process, machine, manufacture, or composition of matter, or any * * * improvement thereof.” Section 100(b) further expands “process” to include “art or method, and * * * a new use of a known process, machine, manufacture, composition of matter, or material.” If the invention, as the inventor defines it in his claims (pursuant to § 112, second paragraph), falls into any one of...the named categories, he is allowed to pass through to the second door, which is § 102; “novelty and loss of right to patent” is the sign on it. Notwithstanding the words “new and useful” in § 101, the invention is not examined under that statute for novelty because that is not the statutory scheme of things or the long-established administrative practice. Section 101 states three requirements: novelty, utility, and statutory subject matter. The understanding that these three requirements are separate and distinct is long-standing and has been universally accepted. The text writers are all in accord and treat these requirements under separate chapters and headings. See, e. g., Curtis’s Law of Patents, Chapters I and II (1873); 1 Robinson on Patents §§ 69-70 at 105 — 109 (1890); 1 Rogers on Patents (1914); Revise & Caesar, Patentability and Validity, Chapters II, III, IV (1936); Deller’s Walker on Patents, Chapters II, IV, V (1964). Thus, the questions of whether a particular invention is novel or useful are questions wholly apart from whether the invention falls into a category of statutory subject matter. Of the three requirements stated in § 101, only two, utility and statutory subject matter, are applied under § 101. As we shall show, in 1952 Congress voiced its intent to consider the novelty of an invention under § 102 where it is first made clear what the statute means by “new”, notwithstanding the fact that this requirement is first named in § 101. The PTO, in administering the patent laws, has, for the most part, consistently applied § 102 in making rejections for lack of novelty. To provide the option of making such a rejection under either § 101 or § 102 is confusing and therefore bad law. Our research has disclosed only two instances in which rejections for lack of novelty were made by the PTO under § 101, In re Bergstrom, 427 F.2d 1394, 57 CCPA 1240, 166 USPQ 256 (1970); In re Seaborg, 328 F.2d 996, 51 CCPA 1109, 140 USPQ 662 (1964). In In re Bergstrom we in effect treated the rejection as if it had been made under § 102, observing in the process that “The word ‘new’ in § 101 is defined and is to be construed in accordance with the provisions of § 102.” 427 F.2d at 1401, 57 CCPA at 1249, 166 USPQ at 262. When § 101 was enacted, the accompanying Reviser’s Note stated (inserts and emphasis ours): The corresponding section of the existing statute [R.S. § 4886] is split into two sections, section 101 relating to the subject matter for which patents may be obtained [“subject to the conditions and requirements of this title”], and section 102 defining statutory novelty and stating other conditions for patentability. H.R.Rep. No. 1923, supra at 6, U.S.Code Cong. & Admin.News 1952, p. 2409, another contemporaneous document, states (emphasis ours): Part II relates to patentability of inventions and the grant of patents. Referring first to section 101, this section specifies the type of material which can be the subject matter of a patent. * * * * * * Section 101 sets forth the subject matter that can be patented “subject to the conditions and requirements of this title.” The conditions under which a patent may be obtained follow, and section 102 covers the conditions relating to novelty. A person may have “invented” a machine or a manufacture, which may include anything under the sun that is made by man, but it is not necessarily patentable under section 101 unless the conditions of the title are fulfilled. Section 102 in paragraphs (a), (b), and (c) repeats the conditions in the existing law relating to novelty. The Senate report, No. 1979, makes the identical statement. The second door then, as we have already seen, is § 102 pursuant to which the inventor’s claims are examined for novelty, requiring, for the first time in the examination process, comparison with the prior art which, up to this point, has therefore been irrelevant. Section 102 also contains other conditions under the heading “loss of right” which need not be considered here. An invention may be in a statutory category and not patentable for want of novelty, or it may be novel and still not be patentable because it must meet yet another condition existing in the law since 1850 when Hotchkiss v. Greenwood, 11 How. 248, 13 L.Ed. 683, was decided. This condition developed in the ensuing century into the “requirement for invention.” See Graham v. John Deere Co., supra. The third door, under the 1952 Act, is § 103 which was enacted to take the place of the requirement for “invention.” We need not examine this requirement in detail for it is not involved in the present appeals, and was not involved in Flook. It will suffice to quote what the House and Senate reports, cited supra — “signals” from Congress — say about the third requirement, from which it will be seen that, again, the claimed invention for which a patent is sought must be compared with the prior art. We quote H.R.Rep. No. 1923, supra at 7 U.S.Code Cong. & Admin.News 1952, p. 2399: Section 103, for the first time in our statute, provides a condition which exists in the law and has existed for more than 100 years, but only by reason of decisions of the courts. An invention which has been made, and which is new in the sense that the same thing has not been made [or known] before, may still not be patentable if the difference between the new thing and what was known before is not considered sufficiently great to warrant a patent. That has been expressed in a large variety of ways in decisions of the courts and in writings. Section 103 states this requirement in the title [“Conditions for patentability; non-obvious subject matter”]. It refers to the difference between the subject matter sought to be patented and the prior art, meaning what was known before as described in section 102. If this difference is such that the subject matter as a whole would have been obvious at the time [the invention was made] to a person [ordinarily] skilled in the art, then the subject matter cannot be patented. [Insertions and emphasis ours.] If the inventor holds the three different keys to the three doors, his invention (here assumed to be “useful” ) qualifies for a patent, otherwise not; but he, as inventor, must meet still other statutory requirements in the preparation and prosecution of his patent application. We need not here consider the latter because appellants have not been faulted by the PTO in their paperwork or behavior. The point not to be forgotten is that being an inventor and having made an invention is not changed by the fact that one or more or all of the conditions for patentability cannot be met. Year in and year out this court turns away the majority of the inventors who appeal here because their inventions do not qualify for patents. They remain inventions nevertheless. It is time to settle the point that the terms invent, inventor, inventive, and the like are unrelated to deciding whether the statutory requirements for patentability under the 1952 Act have been met. There is always an invention; the issues is its patentability. Terms like “inventive application” and “inventive concept” no longer have any useful place in deciding questions under the 1952 Act, notwithstanding their universal use in cases from the last century and the first half of this one. As Mr. Justice Holmes said in Towne v. Eisner, 245 U.S. 418, 425, 38 S.Ct. 158, 159, 62 L.Ed. 372 (1918), “A word * * may vary greatly in color and content according to the circumstances and the time in which it is used.” And Mr. Justice Frankfurter said in Shapiro v. United States, 335 U.S. 1, 56, 68 S.Ct. 1375,1403, 92 L.Ed. 1787 (1948), “It is the part of wisdom, particularly for judges, not to be victimized by words.” We have observed with regret that the briefs filed by the Solicitor General for Acting Commissioner Parker in Parker v. Flook, a case which, as the Court noted, “turns entirely on the proper construction of § 101,” badly, and with a seeming sense of purpose, confuse the statutory-categories requirement of § 101 with a requirement for the existence of “invention.” This they do by basing argument on the opening words of § 101, “Whoever invents or discovers,” thereby importing into the discussion of compliance with § 101 a requirement for “invention” in a patentability sense. But there has not been a requirement for “invention” in the patentability sense in the laws since 1952 — the requirement was replaced by the § 103 requirement for nonobviousness. Graham v. John Deere Co., supra. Furthermore, when one has only compliance with § 101 to consider, the sole question, aside from utility, is whether the invention falls into a named category, not whether it is patentable. Falling into a category, does not involve considerations of novelty or nonobviousness and only those two considerations involve comparison with prior art or inquiry as to whether all or any part of the invention is or is not in, or assumed to be in, the prior art or the public domain. Prior art is irrelevant to the determination of statutory subject matter un der § 101. An invention can be statutory subject matter and be 100% old, devoid of any utility, or entirely obvious. This is our understanding of the statute and the basis on which we proceed to the further consideration of these appeals. The error of the line of argument pursued in the Solicitor General’s briefs in Flook is sufficiently illustrated by quoting from the summation of that argument in the opening paragraphs of the Reply Brief for the Petitioner, pages 1 and 2 (footnotes omitted, all emphasis and bracketed material in original): 1. Respondent errs in asserting (Br. 7 — 13) that our argument confuses the standard of nonobviousness prescribed in 35 U.S.C. 103 and the requirement of statutory subject matter under 35 U.S.C. 101. As respondent recognizes, the patent examiner’s sole ground for rejection of the claims at issue was that they did not cover statutory subject matter under 35 U.S.C. 101. We do not contend that respondent’s particular algorithm for computing updated alarm-limits is not novel or is obvious within the meaning of 35 U.S.C. 102 or 103. We simply contend that the subject matter he seeks to patent is unpatentable under 35 U.S.C. 101, because it is not an “inventpon] or dis-coverfy]” within the meaning of that Section. The plain language of Section 101 requires that the application of a mathematical algorithm involve invention or discovery for it to be patentable. It states that patents may issue only to one who “invents or discovers any * * * process, machine, manufacture, or composition of matter” (emphasis supplied). This language dates from the original Patent Act of 1790. In none of the subsequent amendments to the patent statute has Congress altered this basic requirement. Yet respondent would have the courts ignore this explicit language and adopt a new rule that would allow patents to issue to anyone who “[applies for a patent on ] any * * * process, machine, manufacture, or composition of matter, * * * subject to the conditions and requirements of this title”. Congress could have changed the language of Section 101 to broaden the statutory standards of patentability, but it did not; indeed, respondent agrees (Br. 11) that in the 1952 Patent Act revision, Congress intended to codify the existing judicial precedents regarding the standard of pat-entability. It is transparently clear that the above argument makes the opening words of § 101, “Whoever invents or discovers,” into a requirement for compliance with § 103, the 1952 replacement for the old requirement for “invention”; one must get through the third door in order to get past the first one! That is not the statutory scheme. The statement that respondent Flook was asking for a rule under which “anyone who ‘[applies for a patent on ] any * * * of the § 101 named categories should have a patent “issue” to him is subversive nonsense. There is no issuance without examination for novelty and nonob-viousness. The statement that “Congress could have changed the language of section 101 to broaden the statutory standards of patentability, but it did not” is wholly beside the point because § 101 was never intended to be a “standard of patentability”; the standards, or conditions as the statute calls them, are in § 102 and § 103. The naming of the categories of inventions that may be patented, in whatever statute appearing, has never supplied a standard. The question here, as it always has been, is: are the inventions claimed of a kind contemplated by Congress as possibly patentable if they turn out to be new, useful, and unobvious within the meaning of .those terms as used in the statute. For a better understanding of the issues presented by the present appeals, one further matter should be pointed out. An “invention” in the popular sense may have many aspects in the patent law sense and, technically speaking, may really be an aggregation of closely related inventions all pertaining to the same contribution the inventor is making to the technological arts. This will later be seen to be the case with the inventions of Bergy and Chakrabarty. When that is so, the applicant is in a position to define his invention(s) in claims (technical legal definitions of the spheres of protection sought, not descriptions of the invention) which may fall into different § 101 categories. For example, an inventor may have produced a new product which is made by a new process and put to a new use. The invention is capable, therefore, of being defined or claimed as a manufacture or composition of matter, as a process for making the product, and as a process utilizing the product in some way. The PTO has procedures under which it may or may not permit claims of differing types to be prosecuted in the same patent application. In each of the cases here on appeal, the application contains claims of different types— to process and to product. In each application the process claims have been approved — stand “allowed” — only product claims being rejected and on appeal; but in each application all of the claims pertain to the same invention, considered broadly and in terms of the contribution of the inventor. Before explaining the Bergy and Chakra-barty inventions, we shall state our understanding of the views expressed by the Supreme Court in the Flook opinion and the light shed thereby on the problems before us. In Light of Parker v. Flook We are redeciding these appeals, as directed, “in light of Parker v. Flook.” The parties were given the opportunity in briefs and oral argument to tell us what bearing Flook has on these appeals. As might have been foreseen, the results are not helpful. The PTO says the fact of remand should mandate affirmance and be “taken to buttress the positions taken by the dissenting judges.” The only specific thing seized upon, as a launching pad for argument, is a rhetorical passage quoted from Deepsouth Packing Co. v. Laitram Corp., 406 U.S. 512, 531, 92 S.Ct. 1700, 32 L.Ed.2d 273 (1972), about looking for a signal from Congress before changing well-established law, a situation in no way involved here as will be discussed later. As everyone has conceded, we are dealing with appeals raising an issue of first impression in the courts, the effect on compliance with § 101 of the fact of being “alive.” Appellants and amici collectively tell us that Flook has no bearing, that it did not deal with the issue here, that we were right the first time, and that the reason for remand is unclear. In short, we can read more for ourselves than we have been told. We have read and analyzed Flook diligently- The only thing we see in common in these appeals and in Flook is that they all involve § 101. Flook was a review of one of the many appeals we have heard involving the general theme of the patentability of computer programs. The only way to claim a program is as a programmed “machine” or as a “process” or “method.” The Flook invention was claimed as a “process” under § 101. That was the second case of its kind from this court reviewed by the Supreme Court, the first being Gottschalk v. Benson, 409 U.S. 63, 93 S.Ct. 253, 34 L.Ed.2d 273 (1972), which involved two method claims. Method and process claims are equivalents. Flook appears to have been decided on the authority of Benson. No method or process claim is here involved. In fact, the PTO has allowed (all three doors, §§ 101-2-3, passed) Bergy’s method claims 1 through 4 and Chakrabarty’s process claims 27 through 29, thereby holding that the process aspects of their inventions are not only subject matter within § 101 but also new and unobvious under § 102 and § 103, therefore patentable. Flook was concerned only with the question of what is a “process” under § 101, in the context of computer program protection. No such issue is presented in either of these appeals. There is no better authority on what the Supreme Court has decided in a case than the Court itself and we are fortunate to have its own summary of what it decided in Flook. It appears at the end of footnote 18, 437 U.S. at 595, 98 S.Ct. at 2528, as follows: Very simply, our holding today is that a claim for an improved method of calculation, even when tied to a specific end use, is unpatentable subject matter under § 101. We do not venture to elaborate. The appeals here involve no method of calculation, and the Flook holding appears to have no bearing. As indicated earlier, we deem it our duty to seek whatever additional light there may be in the Court’s opinion on the meaning of § 101, without restricting ourselves to the holding. It is stated to be well established in patent law that the following are not within the statutory categories of subject matter enumerated in § 101 and its predecessor statutes as interpreted through the years: principles, laws of nature, mental processes, intellectual concepts, ideas, natural phenomena, mathematical formu-lae, methods of calculation, fundamental truths, original causes, motives, the Pythagorean theorem, and the computer-implementable method claims of Benson and Tabbot. The present appeals do not involve an attempt to patent any of these things and the Court’s review of this hornbook law is, therefore, inapplicable to the issue before us, which involves only the construction of the terms “manufacture, or composition of matter.” Another principle stated in Flook is that a “mathematical algorithm” or formula is like a law of nature in that it is one of the “ 'basic tools of scientific and technological work’ ” and as such must be deemed to be “a familiar part of the prior art,” even when it was not familiar, was not prior, was discovered by the applicant for patent, was novel at the time he discovered it, and was useful. This gives to the term “prior art,” which is a very important term of art in patent law, particularly in the application of § 103, an entirely new dimension with consequences of unforeseeable magnitude. Insofar as the present appeals are concerned, the foregoing novel principle has no applicability whatever since, as we have said no formula, algorithm, or law of nature is involved, and there has been no rejection on prior art of any kind in either application. In each, both the examiner and the Board of Appeals expressly stated that no references evidencing prior art have been relied on or applied. Insofar as the general patent law is concerned, however, the above-stated novel Flook doctrine may have an unintended impact in putting an untimely and unjustifiable end to the long-standing proposition of law that patentability may be predicated on discovering the cause of a problem even though, once that cause is known, the solution is brought about by obvious means. Such causes may often be classed as laws of nature or their effects. For examples, see Elbel Process Co. v. Minnesota & Ontario Paper Co., 261 U.S. 45, 67-69, 43 S.Ct. 322, 67 L.Ed. 523 (1922); In re Roberts, 470 F.2d 1399, 176 USPQ 313 (Cust. & Pat.App.1973); In re Conover, 304 F.2d 680, 49 CCPA 1205, 134 USPQ 238 (1962). The potential for great harm to the incentives of the patent system is apparent. It is one thing to say that a principle, natural cause, or formula, per se, is not within the categories of § 101, but quite another to say it is “prior art” in determining the nonobviousness of an invention predicated on it even though the inventor discovered it. One final matter with respect to Flook remains. In the PTO supplemental brief on remand, the solicitor places great emphasis on part of a passage which Flook quoted from the opinion of Mr. Justice White for the majority in Deepsouth Packing Co. v. Laitram Corp., 406 U.S. 518, 531, 92 S.Ct. 1700, 1708, 32 L.Ed.2d 273 (1972): We would require a clear and certain signal from Congress before approving the position of a litigant who, as respondent here, argues that the beachhead of privilege is wider, and the area of public use narrower, than the courts had previously thought. No such signal legitimizes respondent’s position in this litigation. While the solicitor believes that the entire opinion in Flook is relevant to the issue here, he says “the above quotation from Deepsouth reaches the heart of the matter.” We disagree. We cannot find in this passage any clear direction signal unless we wrench it out of the context in which it belongs and use it in a manner unwarranted by the situation which spawned it. When we examine the portion of the paragraph in Deepsouth (also quoted in Flook) just preceding the solicitor-quoted passage, its meaning becomes clear. The Court stated: “It follows that we should not expand patent rights by overruling or modifying our prior cases construing the patent statutes, unless the argument for expansion of privilege is based on more than mere inference from ambiguous statutory language.” (Emphasis ours.) The issue in Deepsouth was whether petitioner infringed by selling the unassembled parts of machines embodying patented combinations ,i^;|greign buyers who assembled and used them abroad. The relevant statutory provision, 35 U.S.C. § 271, defines infringement by defining the infringer as anyone who “without authority makes, uses or sells any patented invention, within the United States during the term of the patent therefor * * * (Emphasis ours.) In deciding the case, the Court pointed out that a long line of judicial authority had established the meaning of the term “makes” contrary to the meaning urged by the respondent, with the result that the petitioner’s sales of the parts to foreign buyers were not sales of “any patented invention” which was “made” in the United States, and, thus, were not acts of infringement. It is in this context that the Court made the quoted statement. The respondent in Deepsouth was asking the Court to expand established patent rights territorially, or to treat making parts of a machine as making the machine, by modifying prior cases construing the patent statutes. The Court refused, producing the quoted passage in the process. We do not find the quoted passage to have any bearing on our problem. We are not faced with a litigant urging upon us a construction of § 101 which is at odds with established precedent. Rather, we deal with a case of first impression. Not having been asked to make a change in existing law or to overrule or modify any case or to expand any right given by Congress, we need in this case no signal from that body. To conclude on the light Flook sheds on these cases, very simply, for the reasons we have stated, we find none. The Inventions of Bergy and Ghakrabarty 1. Bergy, Coats, and Malik These inventors, whom we collectively call “Bergy,” provided the usual abstract in their patent application, which is a succinct statement of what they invented. It reads: Microbiological process for preparing the antibiotic lincomycin at temperatures ranging from 18 °C. to 45 °C. using the newly discovered microorganism Strepto-myces vellosus. The subject process advantageously results in the preparation of lincomycin without the concomitant production of lincomycin B (4'-depropyl-4'-ethyllincomycin). The absence of linco-mycin B production results in increased lincomycin recovery efficiency. It is noted from this statement that Bergy invented a process for producing an old antibiotic and in the course of doing so discovered a previously unknown microorganism. The close relationship of the two inventions is apparent from the fact that it is this microorganism which, under the proper fermentation conditions, produces the antibiotic lincomycin, which had previously been produced from a different microorganism called S. lincolnensis and identified by the deposit number NRRL 2936. This former process was the subject of U.S. patent No. 3,086,912. The microorganism which Bergy discovered has the identifying number NRRL 8037. The application was filed with four claims to Bergy’s process, all of which the examiner allowed. Claim 1, the only independent process claim, reads: A novel process for preparing the antibiotic lincomycin which comprises cultivating Streptomyces vellosus, having the identifying characteristics of NRRL 8037, and lincomycin-producing mutants thereof, in an aqueous nutrient medium under aerobic conditions until substantial antibiotic activity is imparted to said medium by the production of lincomycin. As is obvious, that process is an industrial process in the pharmaceutical branch of the chemical industry and is performed by cultivating a living organism which produces the desired antibiotic. Were it not for the life process, nothing would happen. Since the process has been held to be patentable by the PTO, that claim and allowed claims 2, 3, and 4 dependent from it are not before us. By a preliminary amendment, filed before the examiner acted on the application, appealed claim 5 was added together with the attorney’s statement that “Basis for claim 5 can be found throughout the disclosure.” Claim 5 reads: A biologically pure culture of the microorganism Streptomyces vellosus, having the identifying characteristics of NRRL 8037, said culture being capable of producing the antibiotic lincomycin in a recoverable quantity upon fermentation in an aqueous nutrient medium containing assimilable sources of carbon, nitrogen and inorganic substances. The designation “NRRL 8037” in the claims is elucidated by the following statement in the specification. The Microorganism The novel actinomycete used according to this invention for the production of lincomycin is Streptomyces vellosus. One of its strain characteristics is the production of lincomycin without the concomitant production of lincomycin B. Another of its strain characteristics is the production of comparable titers of lincomy-cin at a temperature of 28 °C. and 45 °C. A subculture of this living organism can be obtained upon request from the permanent collection of the Northern Regional Research Laboratories, Agricultural Research Services, U.S. Department of Agriculture, Peoria, Illinois, U.S.A. Its accession number in this repository is NRRL 8037. The specification continues: The microorganism of this invention was studied and characterized by Alma Dietz of the Upjohn Research Laboratory- What follows that statement is an elaborate, highly technical, detailed description of the microorganism, including its type designation as “Streptomyces vellosus Dietz, sp.n.,” occupying over ten pages of the printed specification, followed by exemplary descriptions of the production of lin-comycin therefrom by fermentation processes and the recovery of the lincomy-cin produced by the fermentation. A patent draftsman faced with the problem of obtaining protection for Bergy’s invention necessarily had to begin with a determination of what Bergy had produced that is useful, new, and unobvious and what statutory category or categories it fits into. The problem was how to claim the invention. There were the usual options. Ber-gy’s claim draftsman appears to have first determined that Bergy had invented a new and improved process of making lincomycin which could be conducted with advantage at higher temperatures so that less cooling was required and with the further advantage of less production of unwanted linco-mycin B. The invention was, therefore, claimed as a process, as set forth in allowed claim 1, supra. It appears that further analysis by the claim draftsman of what was new and nonobvious about the process developed the insight that it was Bergy’s development of the biologically pure culture of Streptomyces vellosus, the microorganism which he discovered, the pure culture of which was the one thing which made the process possible. The process is the use of the culture; it is the microorganism culture which makes the lincomycin. Without the culture, the process does not exist. Bergy’s invention might be said to “reside in” the culture which he made of the microorganism he discovered. Another way of defining his invention in a claim, therefore, was to define the culture, as claim 5 does. Ber-gy says the culture of claim 5 falls into either the “manufacture” or the “composition of matter” category of § 101. It does not matter to our decision which it is as the PTO makes no differentiation. The PTO simply says it can be neither. If, as the allowance of claim 1 indicates, Bergy’s invention, when defined as a process, is patentable because it meets all of the requirements and conditions of the patent statutes, why is it not patentable when defined as in claim 5? That is the sole problem posed by Bergy’s appeal. We shall return to it after we have explained the rejection. 2. Chakrabarty Chakrabarty’s invention is in the relatively new and highly complex field of cellular or genetic engineering or microbial genetics. His specification is in such technical terms that it commences with the definition of some 17 terms. We shall refer only to 3 which seem necessary to give meaning to the claims we shall mention. Like Bergy’s invention, Chakrabarty’s is concerned with microorganisms. Unlike Bergy’s which manufactured antibiotics, Chakrabarty’s were engineered to solve another one of man’s practical needs, getting rid of oil spills. This they do by breaking down or “degrading” the components of the oil into simpler substances which serve as food for aquatic life whereby the oil, assumed to be floating on the sea, is absorbed into it. Chakrabarty s invention is illustrated, with respect to its use, in connection with the degradation of crude oil and “Bunker C” oil, which are described as follow: Crude oils, of course, vary greatly (depending upon source, period of activity of the well, etc.) in the relative amount of linear aliphatic, cyclic aliphatic, aromatic and polynuclear hydrocarbons present, although some of each of these classes of hydrocarbons is typically present in some amount in the chemical make up of all crude oils from producing wells. Bunker C is (or is prepared from) the residuum remaining after the more commercially useful components have been removed from crude oil. This residuum is very thick and sticky and without significant use, per se. Thus, “oil” is a mixture of several component hydrocarbon compounds and the ability to break down one component is not the ability to break down oil. Chakrabarty’s specification gives the following explanation: Microbial strains are known that can decompose individual components of crude oil (thus, various yeasts can degrade aliphatic straight-chain hydrocarbons, but not most of the aromatic and polynuclear hydrocarbons). Pseudomonas and other bacteria species are known to degrade the aliphatic, aromatic and polynuclear aromatic hydrocarbon compounds, but, unfortunately any given strain can degrade only a particular component. For this reason, prior to the instant invention, biological control of oil spills had involved the use of a mixture of bacterial strains, each capable of degrading a single component of the oil complex[,] on the theory that the cumulative degradative actions would consume the oil and convert it to cell mass. This cell mass in turn serves as food for aquatic life. However, since bacterial strains differ from one another in a) their rates of growth on the various hydrocarbon components, b) nutritional requirements, production of antibiotics or other toxic material, and c) requisite pH, temperature and mineral salts, the use of a mixed culture leads to the ultimate survival of but a portion of the initial collection of bacterial strains. As a result, when a mixed culture of hydrocarbon-degrading bacteria are deposited on a oil spill the bulk of the oil often remains unattacked for a long period of time (weeks) and is free to spread or sink. In essence what Chakrabarty invented was new strains of Pseudomonas having the new capability within themselves of degrading several different components of oil with the result that degradation occurs more rapidly. This he did by transmission into a single bacterial cell of a plurality of compatible “plasmids,” thereby creating the new strains. The specification discloses two such new strains on deposit with the Department of Agriculture’s Northern Regional Research Laboratories, NRRL B-5472 and NRRL B-5473. Before proceeding further, we quote some of the definitions from the specification: Extrachromosomal element ... a hereditary unit that is physically separate from the chromosome of the cell; the terms “extrachromosomal element” and “plasmid ” are synonymous; when physically separated from the chromosome, some plasmids can be transmitted at high frequency to other cells, the transfer being without associated chromosomal transfer. [Second emphasis added.] * * * * * * Plasmids are believed to consist of double-stranded DNA [deoxyribonucleic acid] molecules. The genetic organization of a plasmid is believed to include at least one replication site and a maintenance site for attachment thereof to a structural component of the host cell. * * * * * * Degradative pathway . . . a sequence of enzymatic reactions (e. g. 5 to 10 enzymes are produced by the microbe) converting the primary substrate [i. e., oil] to some simple common metabolite, a normal food substance for microorganisms. To create his new strains of microorganisms, Chakrabarty started with a strain of Pseudomonas aeruginosa, which itself exhibited no capacity for degrading any component of oil. By a unique process, the details of which we need not consider, he transferred four plasmids, having the individual capabilities for degrading n-octane (a linear aliphatic hydrocarbon), camphor (a cyclic aliphatic hydrocarbon), salicylate (an aromatic hydrocarbon), and naphthalene (a polynuclear hydrocarbon), into the Pseudo-monas aeruginosa bacterium that previously had none of the plasmids in question. This resulted in a new strain having new capacities to produce numerous enzymes to degrade four main components of oil. Chakrabarty thus describes how to use his new bacterium: In practice an inoculum of dry (or lyo-philized [freeze-dried]) powders of these genetically engineered microbes will be dispersed over (e. g. from overhead) an oil spill as soon as possible to control spreading of the oil * * * . A particularly beneficial manner of depositing the inoc-ulum on the oil spill is to impregnate straw with the inoculum and drop the inoculated straw on the oil spill where both components will be put to use — the inoculum (mass of microbes) to degrade the oil and the straw to act as a carrier for the microbes and also to function as an oil absorbent. Other absorbent materials may be used, if desired, but straw is the most practical. [Emphasis ours.] We turn now to the claiming of Chakra-barty’s invention, hoping that the foregoing explanation of what he invented, though undoubtedly technically inadequate, is not too inaccurate and is sufficient to present clearly the legal issue. It is clear enough that the central core of the invention is a new strain or strains of bacteria, and that part of the invention is a process of combating oil spills. The patent draftsman presented four groups of claims; two groups have been rejected and two allowed, the former group being the claims on appeal. Claims of the first group, 7-9, 13, 15, 17, and 21, are directed to a bacterium. Claim 7 is the only independent claim and the others are dependent from it. Claim 7 reads: 7. A bacterium from the genus Pseudomonas containing therein at least two stable energy-generating plasmids, each of said plasmids providing a separate hydrocarbon degradative pathway.[] The second group, 21 and 24 — 26, are directed to an inoculum, the only independent claim being 21 which reads: 21. An inoculum for the degradation of a pre-selected substrate comprising a complex or mixture of hydrocarbons, said inoculum consisting essentially of bacteria of the genus Pseudomonas at least some of which contain at least two stable energy-generating plasmids, each of said plasmids providing a separate hydrocarbon degradative pathway. It will be noted that claims 7 and 21 are but alternative ways of claiming substantially the same thing since the inoculum consists essentially of the bacterium. As we saw earlier, the inoculum may be a dried preparation of the new bacteria in the form of a powder. These two groups of claims are under rejection as not being “manufactures” or “compositions of matter” within § 101. The third group consists of claims 27 — 29 directed to a process or improvement in a process of transferring plasmids from a donor to a recipient bacterium. The fourth group consists of claims 30-32, 35, and 36 directed to an inoculated medium, the only independent claim being claim 30 which reads: 30. An inoculated medium for the degradation of liquid hydrocarbon substrate material floating on water, said inoculated medium comprising a carrier material able to float on water and bacteria from the genus Pseudomonas carried thereby, at least some of said bacteria each containing at least two stable energy-generating plasmids, each of said plasmids providing a separate hydrocarbon degradative pathway and said carrier material being able to absorb said hydrocarbon material. These claims of the last two groups of claims have been held to be patentable by the PTO and have been allowed. Therefore, Chakrabarty will be able to have a patent on his invention as defined therein. Comparison of claim 30 with rejected claims 7 and 21, supra, shows that it differs from them in substance only in adding to the bacterium of claim 7 or the inoculum of claim 21 a “carrier” which will float on water and absorb oil. As shown above, the preferred carrier is straw. The significance of this is that the PTO obviously has no hesitation in issuing a patent on the living bacterium or inoculum when applied to or mixed with straw, which combination it must consider to be a manufacture or a composition of matter under § 101, but refuses to issue a patent on the new bacterium or inoculum itself which is Chakrabarty’s real contribution to the technological arts. The Rejections 1. Chakrabarty We take up Chakrabarty’s application first because it was the first to be filed and the first to be decided by the PTO board, as we stated at the beginning of this opinion. The PTO Board of Appeals said the examiner rejected the appealed claims as not within § 101 for two reasons: (1) the claimed microorganisms are “products of nature” and (2) the claims “are drawn to live organisms.” However, we do not find in the examiner’s final rejection or Answer on the appeal any rejection other than (1). Rejection (2) appears to have been created in the board by misreading the Answer. In expressly reversing ground (1), the board said: We agree with appellant that the claimed bacteria may not be considered as being “products of nature” simply because from the record we must conclude that Pseudomonas bacteria containing two or more different energy generating plasmids are not naturally occurring. This left only ground (2), which the board sustained. In its opinion it said it had examined the cases cited by the examiner and appellant and others as well and had found “no case dealing directly with the point here in issue * * It viewed the question before it as “whether living organisms (appellant’s modified bacterium) are patentable subject matter under 35 U.S.C. 101.” It next said, “We realize that 35 U.S.C. 101 does not expressly exclude patents on living organisms * * It then propounded the theory the PTO has pursued ever since to the effect that Congress could not have intended § 101 to include any living thing because, if it had, Congress would not have found it necessary to pass the Plant Patent Act of 1930 (Pub.L. No. 245, 46 Stat. 376) which amended R.S. § 4886,
