¶136 C.C.P.A. (Patents)
¶2J. Harold Kilcoyne, of Washington, D. C., for appellant.
¶3W. W. Cochran, of Washington, D. C. (H. S. Miller, of Washington, D. C., of counsel), for Commissioner of Patents.
¶4Before GARRETT, Chief Judge, and HATFIELD, JACKSON, O’-CONNELL, and JOHNSON, Judges.
¶6On February 21, 1944, appellant filed his application, serial No. 523,301, for a patent for an “Automatic Hydraulic Synchronizer.” The tribunals of the Patent Office allowed nine article claims and rejected all of the method .claims, 22 to 27, inclusive. From the decision of the board affirming the examiner in rejecting ‘those claims, this appeal has been taken.
¶7The application relates to a method of, -and -an apparatus for, automatically synchronizing two or more rotary machines, which are not of themselves capable of operating -in synchronism. The term “synchronism” as used here means the coordinating of motion timing in at least -two independent machines so .that they may operate a-t the same speed through the governing of a master speed means.
¶8As illustrative of the invention, appellant discloses -an apparatus by means of which the synchronizing of -the engines of a -multi-engine aircraft .is obtained. The synchronization, it is stated, results .from so controlling the -pitch of the propellers that despite variations in the loads on the respective engines, an -adjustable constant rate of engine speed is -obtained. The method of appellant, as may be observed in the illustrative claims, including the production of a series -of timed hydraulic impulses indicative of the master -speed, and the utilization of the impulses in the application of hydraulic speed .controls to an engine -or engines, which may be -out -of synchronism with the master speed means.
¶9It is stated in the brief of -appellant that the Primary Examiner acknowledged -that the invention is broader than the -example hereinbefore set -out, for the reason that • he referred to the synchroniz-able engines as “prime movers.”
¶10Claims 22 and 26 are illustrative of th-e rejected claims and read as follows:
¶11“22. The herein described method of synchronizing the speed -of a plurality of engines with respect to a master speed which includes producing a series -of timed hydraulic impulses indicative -of said master speed, and utilizing said impulses to apply -corrective hydraulic speed control measures to an -engine which may be -out of synchronism with the master speed.
¶12“26. In a synchronous mechanical system comprising a master speed setter and a plurality of engines equipped with speed regulating means, -the herein described method in -the art -of synchronizing the speeds of any of the engines with that of -the master speed setter which consists in generating periodic hydraulic -impulses indicative of the speed of th-e master speed setter, transmitting said impulses, utilizing said impulses to compare the speed of each of -the -engines with that -of the master speed setter, and regulating the speed of any engine -out of synchronism with the master speed setter to -establish and maintain synchronism wit-h said master speed setter.”
¶13The Primary Examiner relying on the case of In re Ernst et al., 71 F.2d 169, 21 C.C.P.A., Patents 1235, rejected the involved -claims solely on the ground that they are improper method claims because they m-erely set -out a function of -the disclosed apparatus, the claims for which -have been allowed. In its -decision, the B-oard ■of Appeals affirmed the action of the Primary Examiner rejecting the involved -claims and denied -two petitions for -reconsideration in -further decisions.
¶14The only issue here is whether or not the rejected claims -define a method distinct from the mere functioning of th-e -disclosed apparatus.
¶15-Counsel f-or appellant in his brief argues that the issue 'has been confused by the ■tribunals of the Patent Office, for -the alleged reason that the board created an unprecedented issue, which issue, as stated in his brief, is whether or not an applicant for a patent seeking method -claims -on a disclosed apparatus must be required to describe in his application other apparatus by which the -claimed method may be -operated, or must include -in the application as filed a statement, presumably with acceptable technical support, that 'the claimed method can be -carried -out manually.
¶16 We do not think that the decision of the board may be fairly interpreted as appellant contends. It is true that in -the first decision -of the 'board it is «tat-*302ed that, “we find no description of any other apparatus in which the method may be performed.” But we do not think that by such statement the hoard intended to hold that an -applicant must describe in his application -other apparatus by which his claimed method may be performed to be entitled to the allowance of method claims, or must include the filing of a statement a-s contended for by -appellant. The hoard merely passed upon the facts before it -and clearly -did not intend to announce a general rule as to what kind -of a disclosure may be necessary to support claims such as are here involved. Of course, if it is obvious from th-e -disclosure that -a method may he performed by means other 'than those disclosed in an application for a patent, there can be no necessity for a showing in that respect. If, however, such other means are no-t obvious, we think what was said in the case of American Lava Co. et al. v. Steward et al., 6 Cir., 1907, 155 F. 731, 738, is applicable. In that case it was stated as follows:
“No doubt it -is -competent, when the circumstances permit it, for an inventor in describing a machine or apparatus which he has devised, to make a claim for a process which his patented -device i-s capable of carrying out. Bu-t to entitle -him to do this th-e process must be one capable of being carried out by other -means than by -the operation of -his .patented -machine, and, unless such other means are known or within the reach of ordinary skill and judgment, the patentee is bound to point them out; for, unless the public are informed by what other means -the process can be carried on, the .process is to them nothing else than the operation of the machine — in other words, 'the exercise o-f its functions.”
¶17See also Chisholm-Ryder Co., Inv. v. Buck, 4 Cir., 1933, 65 F.2d 735, 736. It follows that, wher-e the record indicates a -single means -of carrying ou-t the process and other independent means are not obvious, a process claim which merely states the function or effect of a machine must be held to he -unpatentable under the long ■established rule -of this and other courts.
¶18Appellant contends in his brief that his concept -of synchronizing must hav-e preceded the concept for his apparatus. We are unable to see what difference the -sequence of concepts -has to do with th-e issue here, whi-ch is merely whether -or not the rejected claims are allowable upon the disclosure of th-e application a-s actually presented.
¶19Counsel for appellant vigorously contends in both his -brief and in oral argument that the rejected claims are distinct from the allowed claims -of the disclosed apparatus, for the reason that -the claimed method may be carried -out by other -apparatus or by -hand. If such contention were true, appellant would be entitled to the allowance of -the involved claims. Bu-t if it appears to us, as it did to the tribunals of the Patent Office, that the involved claims merely set f-o-rth t-h-e -function of the disclosed apparatus, then the decision of th-e hoard must he affirmed.
¶20With respec-t to the practice of appellant’s method by hand, it is stated in his brief that his system is “manually operable, -a-t least in part.” While probably there ■is a 'disclosure that the apparatus can be controlled by manual -operation, -such control and the carrying out -of the operation -of the method are entirely distinct. The production or -generation of a series of timed -or periodic impulses, as set out in the claims, indicates that at least -some apparatus is required to produce the hydraulic impulses, and while s-uoh -impulses may be controlled by hand operation, it does not follow that the hydraulic impuls-es are produced by hand performance. Therefore, we are of the opinion that, -as we stated in the case of In re Wadman, 94 F.2d 993, 25 C.C.P.A., Patents, 936, it is not good -sense in.the present -case to -consider the operation of the method by hand. In the case of In re Parker, 79 F.2d 908, 23 C.C.P.A., Patents, 721, relied upon -by appellant, it appeared tha-t hand operation was possible. Therefore, we find nothing in that case applicable to the -present i-ssue.
¶21Counsel for appellant urges that appellant has conclusively established that the method defined by -the -rejected claims c-an be carried -out by means other -than those specifically disclosed. In support of that contention, appellant -states, “that the rotary pulsing valve 40 could be sub*303stituted by a can driven poppet valve,” and that such change had been brought to the attention of the tribunals below. However, such substitution in our opinion does not change the essential character of the disclosed apparatus. The following statement appearing in the case of Black-Clawson Co. v. Centrifugal Engineering & Patents Corporation, 6 Cir., 1936, 83 F.2d 116, 120, seems apposite here:
“And a process wh-ioh cannot be described otherwise 'than by describing the characteristic function of a machine is not validated by showing it may be carried on by another machine which has the same characteristic function in respect to the precise result to be attained(Italics ours.)
¶22We are of the opinion that appellant has not made a clear showing that his method defined in 'the rejected claims can be carried out by any other means except by the apparatus of his disclosure.
¶23For the reasons stated herein, the decision of the Board of Appeals is affirmed.
¶24Affirmed.
