Opinions

RICH, Judge.

This appeal by an applicant for a patent, assignor to General Electric Company, is from a decision by the United States Patent and Trademark Office (PTO) Board of Appeals (board) affirming the rejection of claims 7-9, 13, 15, 17, 21, and 24-26 of application serial No. 260,563, filed June 7, 1972, entitled “Microorganisms Having Multiple, Compatible Degradative Energy-Generating Plasmids and Preparation Thereof.” We reverse.

The Invention

In view of the legal issue presented, it is unnecessary to describe in detail the subject matter of the appealed claims, which is described in complicated biological terminology and is of a highly technical nature involving the modification of bacteria to solve man’s practical needs. In this instance, the immediate need is the important one of controlling oil spills, as one example, by the degradation of complex hydrocarbons such as crude oil and “Bunker C” oil through the action of microorganisms. Microorganisms, that is to say bacteria, are modified for this purpose by what is sometimes referred to as “genetic engineering,” a term appearing in appellant’s specification. It is also disclosed therein that prior to appellant’s invention microbial strains were known that can decompose individual components of crude oil, any given strain degrading only a particular component of the oil. For this reason biological control of oil spills had involved the use of a mixture of strains on the theory that the cumulative degradative actions would consume the oil and convert it into a cell mass which, in turn, serves as food for aquatic life. However, in the use of such a mixture there was ultimate survival of but a portion of the initial collection of bacterial strains with the result that the bulk of the oil spill remained unattacked for a long period. Appellant’s invention involves the creation of a new strain of bacteria by the incorporation in a single cell, by transmission thereinto of a plurality of compatible “plasmids,” of a capacity for simultaneously degrading several different components of crude oil with the result that degradation occurs more rapidly. To make this nontechnical description somewhat more intelligible we quote from the specification but two of its many definitions:

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.
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.

This sketchy background, it is hoped, will give some idea of the nature of the invention at bar as defined in illustrative claim 7 which reads:

7. A bacterium from the genus Pseudomonas containing therein at least two stable energy-generating plasmids, each [42] of said plasmids providing a separate hydrocarbon degradative pathway.1

The specification disclosure contains examples of bacterial strains with four hydrocarbon degradative pathways and the statement: “If there is an upper limit to the number of energy-generating plasmids that will be received and maintained in a single cell, this limit is yet to be reached.”

The PTO, speaking through the examiner as well as the board, has not questioned that appellant has invented and adequately disclosed strains of bacteria, within the definitions of his rejected claims, which are new, useful, and unobvious.

Neither has any question beeri raised by the PTO about the inventions of the rejected claims being in the useful or technological arts so that their protection for a limited time by patent would be an implementation of the Constitutional purpose of promoting progress in the “useful arts.” Art. I, sec. 8, clause 8.

The Rejection and the Board’s Decision

The decision and opinion of the board are quite similar to its action and reasoning in the recent case of In re Bergy, 563 F.2d 1031, 195 USPQ 344 (Cust. & Pat.App.1977), wherein we reversed the decision of the board (subsequent to its decision herein).

In the present case, the board first pointed out that the examiner had rejected the appealed claims only under 35 U.S.C. § 1012 “on the ground that they are not encompassed by the provisions” thereof, advancing two reasons therefor: (1) that the claimed microorganisms are “products of nature” and (2) that they are drawn to “live organisms.” The board reversed the examiner on point (1), agreeing with appellant that the claimed bacteria are not naturally occurring. This decision was expressed in a single sentence and the rest of the board’s opinion was devoted to a discussion of the legal effect of the fact that the claimed bacteria are alive.

The board first discussed a number of cases which it had considered and concluded that there is “no case dealing directly with the point here in issue,” including, possibly as of first importance, the Supreme Court’s opinion in Funk Brothers Seed Co. v. Kalo Inoculant Co., 333 U.S. 127, 68 S.Ct. 440, 92 L.Ed. 588 (1948). (In Bergy, supra, the board also stated that it had “not found any case directly in point.”) The board then pursued exactly the same line of reasoning it did in Bergy, in large part in the same words, to reach the same conclusion it expressed in Bergy, that § 101 “does not include living organisms.” The board’s opinion that § 101 does not include any living organism was expressed in the form of its belief that Congress did not so intend. As in Bergy, this view was deduced from the enactment of the Plant Patent Act of 1930, citing' this court’s opinion in In re Arzberger, 27 CCPA 1315, 112 F.2d 834, 46 USPQ 32 (1940).3
