616 F.2d 516 | C.C.P.A. | 1980
Lead Opinion
This appeal is from the decision of the United States Patent and Trademark Office (PTO) Board of Appeals (board) affirming the rejections of claims 2, 3, and 8 in appellant’s application, serial No. 646,309,
The Invention
The new compounds claimed herein, poly-functional nitrile imines, are one aspect of a broader invention which is described in U.S. Patent No. 3,418,285, which issued on a parent application, as follows: “This invention relates to new cross-linking agents, to cross-linking unsaturated polymers therewith, and to the crosslinked products so produced.” The instant application explains that generally any type of unsaturated polymer, containing ethylenic unsaturation wherein there is at least one hydrogen radical attached to at least one of the carbon atoms of the double bond, can be cross-linked with the polyfunctional nitrile imines and that the resulting cross-linked polymers are hard, tough rubbers, substantially insoluble in water and hydrocarbon solvents with improved tensile properties useful in various rubber applications.
The following quotations from appellant’s specification are particularly relevant to the issue before us:
The polyfunctional nitrile imines of this invention are relatively unstable compounds, and the primary modes of cross-linking unsaturated polymers with these imines involves their formation in situ in a polymer mass from their closely related but more stable hydrogen chloride salts * * * usually accomplished by contacting the hydrazide chloride with an alkaline material. * * *
******
The cross-linking is carried out by contacting the unsaturated polymer and a minor amount of the polyfunctional nitrile imine cross-linking agent for a time sufficient for the desired degree of cross-linking to occur. This uniform contacting is preferably achieved by uniformly mixing the polymer and the hydrogen chloride salt of the polyfunctional nitrile imine, and treating that mixture with an alkaline material, thereby generating the nitrile imine in situ in the polymer mass. ******
The uniform mixing * * * Can be carried out by milling these ingredients on a conventional rubber mill, by dissolving the hydrogen chloride salt or the tetrazole precursor in a solvent solution of the polymer, or by any of other numerous methods, which will be readily apparent to those skilled in the art. This uniform contacting will result in the nitrile imine cross-linking agent being uniformly distributed throughout the polymer mass upon its in situ generation, so that uniform cross-linking can be achieved.
Thus, the claimed compounds are simultaneously generated and put to use. The three product claims on appeal are in Markush form, covering a large number of nitrile imines, the novelty, utility, and unobviousness of which have not been questioned. In view of the nature of the rejections, it will not be necessary to consider the claims in detail and quoting them would serve no useful purpose.
The Rejection
The examiner relief on no prior art references. He held, first, that the claimed compounds do not fall within any statutory category of invention named in 35 U.S.C. § 101.
A “transitory intermediate” is not a composition of matter provided for under the normal interpretation of this statute. * * *
******
* * * as noted above (and below) this is a situation where a “transitory” intermediate, which would not and could not be readily isolated, is being claimed and one of ordinary skill in the art is not presented with an enabling disclosure (for more on “enablement” see below) for attaining this compounds, [sic] per se, claimed at bar.
Decisions: While no direct precedential decisions have been found that are specifically in point on this 35 U.S.C. [§] 101 issue the following decisions might be of interest: Ex parte Howard, 1924 C.D. 75 (item No. 1 on page 76) and In re Stubbs, 1932 C.D. 466 (item No. 1 on page 467).
The examiner then made a second rejection of the appealed claims under 35 U.S.C. § 112, first paragraph, saying:
The first paragraph is pertinent as this disclosure provides no “enabling” data to teach one of ordinary skill in the art how to prepare and isolate the compounds, per se, presently being claimed. Derivatives yes, but actual isolatable compounds, no.
Put another way, it is clear that as appellant is claiming specific compounds it is appellant’s duty (to fulfill the patent contract granted by the government of the United States)3 to give sufficient teachings to enable one of ordinary skill in the art to produce (or reproduce) and isolate such claimed compounds, per se, not derivatives thereof. As urged by the Examiner, supra, appellant has not done so. If it would be obvious to the ordinary skill in the art how to isolate such claimed compounds then no problem exists as such would be patentable * * * but herein no such enablement is proffered nor is (are) any reference(s) cited to prove such isolation would be within the ordinary skill of the art. [Emphasis ours.]
Another argument made by the examiner was that there was no indication, and certainly no proof, that the claimed compounds “are even formed.” The board disagreed with him on this point and expressly held to the contrary, so that question is not before us. The board held that, on the evidence produced by appellant, it is “reasonable to assume that the claimed compounds, in fact, are formed and do exist in the system disclosed by appellant in which they are specifically and explicitly taught to be produced.” Having so held, the board’s opinion continues as follows:
But we are, nevertheless, constrained to affirm the Examiner’s rejection of the instant claims. An interesting legal question is presented by this case for which, as noted by the Examiner, no direct precedential decisions appear to exist. However, similar factual situations prevailed in Ex parte Howard, 1924 CD 75, wherein a free-falling drop or gob of molten glass which exists only while falling to the mold was claimed, and in In re Stubbs, 58 F.2d 447, [19 CCPA 1216] 423 OG 6, 1932 CD 466, where the subject matter at issue was a paving for streets comprised of a partly-cured concrete. In both of these cases the deciding tribunals [in Howard, Assistant Commissioner of Patents Fenning and in Stubbs this court] held that the claimed products did not fall within one of the statutory classes which may be patented inasmuch as they*519 were transitory and ephemeral in nature. Similarly here, the claimed compounds are transitory intermediates which appellant has not been able to isolate and which apparently are not capable of existence, as such, in isolated form. See Paper No. 5, page 3 of the parent file, Serial No. 453,664, pertinent portions of which have been reproduced by the Examiner in his Answer. Accordingly, we believe that the claimed compounds which admittedly exist only as transitory intermediates are not within the scope of the four categories of inventions or discoveries set forth in 35 USC [U.S.C. §] 101 which may be patented.
Further, we interpret the enablement clause of the first paragraph of 35 USC [U.S.C. §] 112 as requiring that the claimed invention, i. e. the claimed compounds per se which constitute the invention at issue, must be taught in a manner such that the artisan will be in possession of the claimed invention. Appellant, however, does not disclose how this may be achieved nor, in fact, does he even assert that such may necessarily be possible. He only postulates that using very sophisticated techniques someone may one day possibly isolate and analyze the instant compounds. It is urged by him that investigations of this nature are unnecessary for the purpose of this invention.
We disagree. The invention at bar, as defined by the appealed claims, is the compounds, per se, and as long as appellant has failed to give directions to one skilled in the art which would put him into possession of the invention so claimed, he has not satisfied the enablement clause of 35 USC [U.S.C. §] 112. This is not to say that we believe appellant must teach the art-skilled how to isolate the claimed compounds in pure form; but we do believe that appellant must enable one to obtain the compounds in a reasonably stable form. [Emphasis in original.]
The Issue
From the foregoing it is apparent that the board affirmed two distinct grounds of rejection: (1) lack of statutory subject matter under § 101 and (2) lack of an enabling disclosure in the specification under § 112. The matter has here been further simplified, however, by the PTO solicitor in his brief in this court. At the end of his brief he says:
It is the Commissioner’s view that the § 112 rejection stands or falls with the § 101 rejection. If the unstable, non-isolatable, transitory intermediates claimed in claims 2, 3, and 8 are deemed by the Court to be a “composition of matter” within the meaning of § 101, then appellant has at least taught how to make the unstable, non-isolatable, transitory compounds in situ. It is not apparent what more would be required under the circumstances. The Commissioner, of course, believes the ruling below should prevail on the basis of the § 101 rejection.
Thus, the two issues have effectively been reduced to one: Are the claimed compounds, which the board has admitted in fact do exist and can be produced according to the description of appellant’s specification, excluded from the category of “composition of matter” in § 101 because they are transitory, unstable, and non-isolatable in what the board called “a reasonably stable form”? Stated another way, how long must a new and useful compound, which can be made at will for its intended purpose, here as a cross-linking agent, exist to be considered as a “composition of matter” under § 101?
OPINION
The examiner and the board recognized, and the solicitor appears to concede, that the question raised by this appeal is one of first impression and that it is a question of law.
The PTO brief is devoid of any reason for excluding appellant’s compounds from § 101. It merely says they should be excluded because they are unstable and cannot be isolated, but that simply begs the question. It is said that denying appellant
Although the PTO clearly felt, as we feel, that there is no prior decision on facts the same as those here, we will briefly discuss the two cases which were cited and apparently relied on below. The board said of them: •
In both of these cases the deciding tribunals held that the claimed products did not fall within one of the statutory classes which may be patented inasmuch as they were transitory and ephemeral in nature,
Ex parte Howard, 328 O.G. 251, 1924 C.D. 75 (Ass’t. Comm’r. 1922), was decided in the days when a decision of the board of Examiners-in-Chief (now the Board of Appeals) could be appealed to the Commissioner of Patents in person under § 47 of the Patent Act of 1870, R.S. 4910 (repealed by § 6 of Pub.L. 690, 69th Cong., Mar. 2, 1927, 44 Stat. 1326). It was also then settled that the decision of such appeals to the Commissioner in person could be delegated to the Assistant Commissioner. Hence, we had in this case a decision by Assistant Commissioner Penning. The first part of his opinion dealt with a claim rejected on prior art and has no bearing here. The second part dealt with a refusal by the Examiners-in-Chief to admit a new claim directed to "a freely-falling drop or gob of glass” of specified characteristics which was created in the course of a process of glass molding, the molten gob falling into the mold to be shaped into an article before it cools. The issue presented was whether the gob was a “manufacture” under R.S. 4886, predecessor statute to § 101. Assistant Commissioner Fenning held the claimed hot gob was not a “manufacture” for the following reasons:
I am of the opinion that it is the finished product that the patent statutes are designed to protect as “manufactures” and not something which is produced at a particular stage of the manufacturing process and which is evanescent and adapted for use only in so far as it may enter into and be modified by subsequent steps of a method for producing a complete article.
# * * * * #
* * * the drop of glass claimed is in its temporary condition while being transformed into something else. The “manufacture” is not yet made, the process of manufacturing is still incomplete.
That is one man’s opinion on the application of the statutory term “manufacture” to one set of facts. However, the Commissioner had another reason for refusing to admit the new claim. He noted that the principal difference between the applicant’s gob and those disclosed by the prior art lay only in its shape, “the idea being to shape the charge to fit the mold.” And that difference, he said, was “merely one of degree.” He also took note of a photograph filed with the brief which, he said, seemed to show that applicant’s gob was of an old shape and not that of the claim, wherefore “applicant’s argument is from theory and not from practice.”
Ex parte Howard is distinguishable, therefore, on the grounds that it dealt with the construction of “manufacture” rather than “composition of matter,” with a gob of apparently old, or at least obvious, molten glass in a transitory state rather than with novel chemical compounds, and with a mechanical molding process in which it was well known to use a molten gob of glass as distinguished from a novel chemical process using an entirely new and unobvious group of chemical compounds. While certain analogies can be drawn from the reasoning used, we do not regard the Assistant Commissioner’s reasoning as persuasive on the facts before us.
In re Stubbs, 58 F.2d 447, 19 CCPA 1216, 13 USPQ 358 (1932), involved a process for making concrete paving. The affirmance of the rejection of four claims was appealed to this court. All were rejected on prior art. The rejection of two process claims was reversed by this court. The other two claims were directed to paving and are typified by claim 1 reading:
1. Paving for streets, roads, and the like comprising a slab of cut-surface part*521 ly cured concrete, a coating of bituminous material laid on said cut surface and partly embedded therein, and a coating of sand adhering to the bituminous material. [Emphasis ours.]
The examiner had rejected claims 1 and 2 because they relied on a method step. The board disagreed with the examiner on that ground but held those claims were “primarily improper because as drawn they appear to claim a product in its transitory stage instead of in its final form. The finished product includes concrete which is completely cured and not partly cured.” The product, of course was paving. This court, in a single paragraph reiterating the facts, completely agreed with the board, citing no statute or other authority or any other reason in addition to what the board was quoted as saying. Apparently the court felt that a claim to paving, to accurately describe the • invention, should not refer to uncured concrete because the finished product does not contain it. But even that is surmise. The significant fact here is that this court made no reference whatever to the predecessor statute of § 101, nor to any statute or precedent. Nor did it even refer to the question of what subject matter may be patented. Stubbs is totally lacking in precedential value. It simply did not deal with the issue now before us.
Wholly unlike the product claim in Stubbs, which attempted to claim paving consisting of a combination of elements, the claims here are not directed to combinations but to new chemical compounds. In essence, the objection of the PTO is that the compounds, being unstable, cannot be isolated and lays down as a prerequisite to being “statutory subject matter” that “appellant must enable one to obtain the compounds in a reasonably stable form.” That is to say, unstable compounds are not “compositions of matter” under § 101, at least when they are sufficiently unstable, notwithstanding it can be determined that they in fact do exist, that they are useful cross-linking agents, and that they can be produced at will, following appellant’s specification, and used for their intended purpose.
It appears to us that the PTO would read into § 101 a requirement that compositions of matter must be stable — which is a relative term to say the least. We see no good reason to do so. It would appear that many compounds may find their greatest or even their sole utility in the fact that they are not stable. Certainly, in the invention at bar there is no reason to have the claimed compounds in a stable form so they can be bottled or tanked or otherwise stored. The preferred manner of using them is to produce them in situ, whereupon they exhibit their cross-linking activity, their only disclosed utility.
In discussing the § 112 aspect of the rejection, which the solicitor has so helpfully eliminated from consideration, the board expressed concern about putting the artisan in possession of the claimed invention, and rightly so. But it seems to us that the board concentrated unduly on the word “claimed” and was too literal about the need for the artisan to be in possession of the claimed compounds in the sense of holding them for a time in his hands in a “reasonable stable” form. Assuming, arguendo, that the claimed compounds are useful only for cross-linking and only when produced in situ — which would be sufficient utility for patentability — those skilled in the art have been put in possession of them by appellant’s disclosure just as completely as they have been put in possession of appellant’s invention in its process and cross-linked product aspects, now patented.
The solicitor’s brief in this court presents a new argument, not made by the examiner or board, as to why § 101 should be construed to exclude unstable compounds incapable of being isolated. The contention is that 35 U.S.C. § 114, which authorizes the Commissioner, if he so desires, to require models, specimens, and ingredients, compels that conclusion. He says:
It is readily apparent that by authorizing the Commissioner to require samples of a composition of matter, Congress must have intended that a composition of matter qualifying as patentable subject*522 matter be something more than a composition of matter which is unstable and incapable of being isolated.
We see no merit in that argument. Considering the origins and history of § 114, we do not believe that it was ever intended to impose any limitations on the scope of § 101 or that there is any reason why it should. For the origins of § 114 one must hark back to § 3 of the Patent Act of 1793 which included as part of the patent application “drawings and written references, where the nature of the case admits of drawings, or * * * specimens of the ingredients, and of the composition of matter, sufficient in quantity for the purpose of experiment, where the invention is of a composition of matter; * * Section 6 of the 1836 Act added: “and he shall moreover furnish a model of his invention, in all cases which admit of a representation by a model, of a convenient size to exhibit advantageously its several parts.’’. That was before anything like modern chemistry had evolved in a time when the Patent Office was largely a museum of technology. Model and specimen storage and exhibition became an aggravated problem for the Office and in 1870 Commissioner Fisher's recommendation to dispense with all models except when absolutely necessary was written into the law by making the submission of models and specimens discretionary with the Commissioner. Act of 1870, §§ 28, 29, R.S. 4890, 4891 (1874). See Outline History of the Patent Office, 18 JPOS 116, 138, 168, 175 (July 1936). Although models were required by Patent Office rule for a few more years, that rule was finally dispensed with in 1880. Id. at 137.
Section 114
Having considered the case of first impression which this appeal presents and the arguments pro and con, we find the rejection of claims 2, 3, and 8 to be without support in law and the decision of the board is reversed.
REVERSED.
. The present application is a continuation of serial No. 453,664, filed March 21, 1974, which
. § 101. Inventions patentable
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.
. The examiner’s notion about the United States granting a contract is inapt. The Government grants only a right to exclude. There is no other agreement. While a patent has often been likened to a contract on the theory that it is issued in exchange for the disclosure of the invention (the “consideration”), the analogy is inexact. A patent is a statutory right. It is granted to “Whoever” fulfills the conditions, § 101, note 2 supra, unless fraud has been committed.
. § 114. Models, specimens
The Commissioner may require the applicant to furnish a model of convenient size to exhibit advantageously the several parts of his invention.
When the invention relates to a composition of matter, the Commissioner may require the applicant to furnish specimens or ingredients for the purpose of inspection or experiment.
Concurrence Opinion
concurring.
Although I agree with the majority opinion that the mere fact a chemical compound is a “transitory intermediate” is insufficient basis, for excluding the compound from coverage under § 101, I feel constrained to comment on other issues presented by the appeal.
I also disagree with the majority’s treatment of Ex parte Howard and In re Stubbs. Dismissing Howard as “one man’s opinion” and Stubbs variously as “not dealpng] with the issue now before us”
. I observe that the examiner did not consider the opinion affidavits sufficient to prove the existence of the compounds especially in view of appellant’s admission in the specification that the compounds are “transitory” and “are so reactive that they react with each other.” In re Brandstadter, 484 F.2d 1395, 179 USPQ 286 (CCPA 1973); but see In re Sebek, 465 F.2d 904, 59 CCPA 1220, 175 USPQ 93 (1972).
. The board, by its own action, has applied these cases in issues similar to those “now before us” and would, apparently, disagree that they are legally unrelated. Ex parte Dubsky, 162 USPQ 567 (Bd.App.1968); Ex parte Nelson, 109 USPQ 116 (Bd.App.1955). The board, in both Nelson and Dubsky, while discussing the facts of those cases, found them factually distinguishable and reversed the examiner in each.
