Opinion

Garrett, Presiding Judge,

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 decision of the Primary Examiner finally rejecting claims 1,5, and I to 16, inclusive, of appellant’s [867]*867application for patent on method and apparatus for preservation of biologically active substances. Four claims stand allowed.

The specification retíites that “such substances as sera, protein solutions, bacterial cultures, pharmaceutical and glandular substances, viruses and other labile biological substances” are included, and it is stated that the application—

relates more particularly to improvements in processes and apparatus for sealing such substances in final containers under high vacuum after desiccating such substances by freezing them and removing water under a high vacuum.

We quote the following general description from the brief of the Solicitor for the Patent Office:

The process disclosed by appellant’s application * * * comprises freezing the material to be treated and removing the water from it by evaporation in a vacuum while the material is in a frozen condition. In carrying out this process the frozen material, in bottles, is placed in a vacuum chamber and stoppers for the bottles are supported immediately above them by means of an adjustable plate. When the vacuum treatment has been completed, the plate is lowered to force the stoppers into the bottles. Heat is supplied to the vacuum chamber in regulated amounts, to facilitate the evaporation.

Claims Nos. 1, 9, 10, 11, and 15 are directed to the apparatus; the others to the process.

Claims Nos. 1 and 5 seem fairly to illustrate the claimed invention. They read:

1. Apparatus adapted for the production of desiccated biologically active and other material sealed in evacuated containers comprising a chamber adapted to be hermetically sealed provided with an outlet through which the chamber may be evacuated and with a removable wall section, means within said chamber to support a plurality of containers in fixed positions, means within said chamber to support a perforable stopper above each said container, and externally actuated means for introducing said stoppers into the nocks of the containers, and for forcing them into tight engagement therewith to effectively seal the containers.
5. The process of producing desiccated biologically active and other substances in evacuated final containers provided with perforable stoppers which comprises introducing a large number of containers provided with open necks and containing frozen material to be desiccated into a chamber, sealing such chamber, producing a high vacuum within the chamber whereby water is removed from the frozen material, introducing a perforable stopper into the neck of each container and forcing such stoppers into tight engagement therewith, simultaneously and without breaking the vacuum.

The references cited are:

Shipley, 111,264, January 24, 1871.
Tapseott, 649,012, May 8, 1900.
Taylor, 1,340,921, May 25, 1920.
Van Doren, 1,451,351, April 10,1923.
Smith, 1,718,603, June 25, 1929.
Reichel, 2,066,302, December 29, 1936.

[868]*868It appears that of the reference patents cited, that to Reichel is the only one which relates to a biological. As stated in the brief of the Solicitor for the Patent Office, it—

* * * discloses a method of treating biologically active substances which comprises freezing them, evaporating the water from them in a vacuum, while they are still frozen, and applying heat to facilitate the evaporation. The flasks containing the material may be sealed in an evacuated state.

The Smith patent relates to pharmaceuticals, more specifically to ampules for use in mixing drugs. It shows a receptacle having a stopper, preferably of rubber, adapted to be perforated to permit the removal of material, the mouth of the container being flame-sealed .above the stopper.

The Shipley patent discloses apparatus and process for canning and preserving meats, fruits, vegetables, etc. It shows bottles which are held in' a fixed position with their tops in a vacuum chamber, corks fitting loosely in the tops. After the atmosphere is exhausted from the bottles the corks are pressed tightly into them while in the vacuum by a movable head actuated by a screw.

The Tapscott patent discloses apparatus for seating and sealing covers of receptacles, such as cans.and jars, used in canning processes. The receptacles are held in fixed positions in a vacuum chamber, the closures for them being held directly above them by a plate movable from outside the chamber by means of a screw. When the air has been evacuated from the receptacles the plate is moved downwardly and forces the covers simultaneously over the mouth of the receptacle.

Taylor and Van Doren disclose apparatus for forcing closures into receptacles.

The patent to Taylor relates particularly to treating and canning milk, and his operation is carried out in a vacuum.

The patent to-Van Doren relates to apparatus for bottling liquids and illustrates a method of1 sealing by insertion of the stopper. Nothing is said in his patent of the operation being carried out in a vacuum.

' In the statement of the examiner following the appeal to the board, the claims were, in effect, divided into groups, or classes, and that arrangement was followed by the board.

Claims Nos. 1 and 15 (apparatus claims) were grouped together and rejected as unpatentable over Tapscott-

Claims Nos. 9, 10, and 11 (the remaining apparatus claims) were rejected as unpatentable over Shipley, “especially in view of Reichel.”

Process claims Nos. 5, 7, and 8 were held unpatentable over Reichel in combination with Tapseott. The examiner also held this group unpatentable over either Taylor, Shipley, or Tapscott in view of [869]*869Reichel and Smith. Of the latter rejection the board said it “may be considered cumulative.” The examiner also included claim No. 6 in the foregoing group, but his rejection of that claim was reversed by the board, and it stands allowed.

Process claims Nos. 12,13,14, and 16 were rejected by the examiner “on the references and reasons cited against claims 5 to 8 taken with the remarks noted against 9 in reference to the heat,” with the further statements, “Reichel regulates the supply of heat” and “The material in Shipley and Taylor is out of contact with the chamber walls,” and this ground was approved by the board.

It is conceded by appellant that the “underlying” process involved is disclosed by the patent to Reichel. The specification of his application states:

Insofar as the process of freezing and removing the water is concerned, the process which is advantageously used is one described in the Reichel patent 2,066,302, with freezing of the material by indirect exposure to a refrigerant maintained at —70° 0.
