In re Winder
Opinion of the Court
delivered the opinion of the court:
This is an appeal from the decision of the Board of Appeals of the United States Patent Office affirming the rejection by the Primary Examiner of claim 168 of appellant’s application for a patent on a bottle-forming machine and method. The "appeal w-as. originally argued on March 6, 1956, and, by order of the court, was reargued November 7, 1956. Claims 33, 34, 44, 73, 161, 167, and 169 were also included in the notice of appeal but have been withdrawn.
The appealed claim, which is drawn to a method of making glassware, is as follows:
168. In a method of making glassware upon a rotating glass machine-having a set of blank molds around it at one level and a set of finish molds around it at another level thereby providing a plurality of mold sets each having a blank mold and a finish mold: the steps of charging a blank mold at a charging point in the rotation of the machine, with a charge of glass; forming an inverted parison in the blank mold with a portion of its top surface shaped like the final ware, and with its lower parts finished; holding said parison in the mold until it becomes relatively stiff to withstand subsequent transfer to the finish mold; engaging the finished top surface of the stiff parison by interfitting a transfer head therewith and-drawing' a- suction-thereon-; opening-the blank molds swinging the párísoñ to reverted position while holding the suction thereon, and enclosing the same with the section head in the finish mold; reclosing the blank mold and recharging it while the parison is thus within the finish mold, so as to prepare a new párison; forming the parison into finished ware in the finished mold while formation of the subsequent parison is occurring in the blank mold; opening the finish mold and withdrawing the completed ware in time to make the transfer head available to engage the subsequent parison by the time of the completion thereof; and thereafter repeating the cycle.

Appellant’s application discloses a very complicated machine for forming glass bottles. The machine comprises a large rotary turret on which are mounted, at one level, a set of preliminary molds, known as blank molds, and, at another level, a set of finish molds, the arrangement being such that each blank mold is adj acent- to a finish mold. As the turret rotates, the blank molds pass successively under a charging apparatus which deposits in each of them enough glass to form a bottle. The glass is shaped, by automatic devices, in each blank mold to form an inverted preliminary shape, known as a parison, in which the top and bottom portions correspond.to those of the bottle in final form, while the intermediate portion requires further ¿abiding.' Associated with each blank mold is a transfer device which includes a suction head adapted to engage the parison, revert it to upright position, and transfer it to the corresponding finish mold.
After each blank mold receives its charge the turret continues to rotate while the parison is formed and cooled sufficiently to permit its being engaged by the transfer apparatus, whereupon "that apparatus, is automatically operated to remove the parison and place it in the finish mold where it is molded to final form and subsequently removed from the machine. The arrangement is such that a new charge of glass is fed into the blank mold while the first parison is still being shaped in the finish mold.
In sustaining the examiner’s rejection of the appealed claim as being drawn to the fmiction of an apparatus, the board said
* * * We consider that this type of rejection, imposes upon appellant a duty to show the method to be independent of the apparatus, which duty may be discharged by showing that the method may be performed by hand or by other apparatus different from that disclosed in the instant application.
In support thereof, the board cited In re Ernst et al., 21 C. C. P. A. (Patents) 1235, 71 F. 2d 189, 22 U. S. Pat. Q. 28; In re Nichols, 36 C. C. P. A.

According to'our interpretation of the claim before us,, it.appears that the only elements of apparatus -expressly required to be present for the performance of the process of the appealed claim are a “rotating glass machine having a set of blank molds around it at.one level and a set of finish molds around it at. another level, thereby providing a plurality of mold sets each having a blank mold and a- finish mold,” and a suction transfer head.. The recited , arrangement of blank molds and-finish molds at different levels on a rotating glass machine is conventional in the prior art, being shown by both of the earlier patents to Winder, as well as. by the Young and Tremblay patents. The use-.of suction heads for transferring parisons on a rotary glass machine is shown by Slick and by the second Winder patent..- It follows that the claim does not expressly -require any new element, of apparatus or any new arrangement of old elements.
In our opinion the claimed process could be carried out with only tthe conventional elements above .mentioned-and a.source of 'molten glass, with all the steps recited in the claim capable of being performed by hand,;- It seems to.us that for such operation the blank and finish .molds could be mounted on,a rotary turret in the manner above, described, and--a-manually movable suction head mounted on the turret in association with each pair of molds. ' A source' of molten glass could be provided at a point adjacent the turret and the operator could take his station there.
The operator could begin by moving the turret either manually are by controlling a suitable motor until the first pair of molds arrived at his station, and then carry out the first step of the claimed process by manually -inserting a charge of glass in the blank mold. The second step could be carried out by manually operating whatever conventional mechanism was associated with the mold for giving the
' It thus appears that each of the manipulative steps recited in the appealed claim can be carried out by hand with the aid of nothing more than apparatus which was conventional in the art at the time appellant’s application was filed. The complex mechanism described therein and covered in his allowed apparatus claims is, therefore, not necessary to the performance of the claimed process. Since, in our opinion, that process cannot fairly be held to define merely the function of the apparatus, it is necessary to reverse the decision of the Board of Appeals.
Dissenting Opinion
dissenting.
I am of the opinion that the single claim on appeal was properly rejected by the Board of Appeals as being drawn merely to the function of the disclosed apparatus and thus respectfully dissent from the decision rendered by the maj ority of the court.
The applicable law in this case is clear and has been adequately set forth in the majority opinion. There is no question but that, in accordance with said law, unless it can be demonstrated to the court that the claimed process can be carried out by apparatus different from that disclosed in appellant’s application or by hand, the rejection of the board must be sustained.
The majority decision makes no mention of the existence of appa
With respect to the former consideration, it must be noted that appellant has urged that it is possible for the alleged method recited in claim 168 to be performed by an alternate machine. He contends that the Young machine of patent No. 2,328,873 could be combined with the transfer mechanism of appellant’s prior patent No. 2,466,669, and that this combination could perform appellant’s process.
This argument, however, was not pressed before either the examiner or the board. In view of this fact, appellant may not properly raise the point before this tribual. In re Herthel, 36 C. C. P. A. (Patents) 1095, 174 F. 2d 935, 82 USPQ 55.
It remains to be seen whether or not the claimed method may be performed by hand.
The preamble of claim 168 recites the use of a “rotating glass machine having a set of blank molds around it at one level and a set of finish molds around it at another level.” This recitation therefore indicates that a machine having the foregoing characteristics must-be used for performing the alleged method. The next phrase recites “charging a blank mold at a charging point in the rotation of the machine.” Thus, again the machine is inextricably associated with the alleged method. The phrase “forming an inverted parison in the blank mold with a portion of its top surface shaped like the final ware, and with its lower parts finished,” in my opinion, recites a step which can be performed independently of any particular apparatus or by a hand implement, assuming that this phrase is not functional in that it merely recites a desired result. The same can be said of the following phrase which recites “holding said parison in the mold until it becomes relatively stiff to withstand subsequent transfer to the finish mold.” However, the next portion of the claim, which states “engaging ,the finished top surface of the stiff parison by interfitting a transfer head therewith and drawing a suction thereon,” appears to me to recite how the specific machine operates. The next phrase, “opening the blank mold,” is not restricted to the machine under consideration. However, the next phrase, “swinging the parison to reverted position while holding the suction thereon, and enclosing the same with the suction head in the finish mold,” indicates to me the mode of operation of the specific machine in question in that it sets forth the relationship of the parts of the machine relative to the parison.. The remaining portions of the claim are restricted to the cooperation of the various essential elements of the machine, and define their operative relationship to secure the desired result, and, as such, are drawn to the function of the machine. Nothwithstanding
The decision of the Board of Appeals should accordingly be affirmed.
