Opinions

SMITH, Judge.

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 claims 1 to 8, inclusive, 11, 13, 14, 15, 16, 18, 19, 24, 25, and 26 of appellant’s application for a patent on a method of packaging biscuit, on the ground that the method claimed would be obvious in view of prior patents. Claims 11, 14, 18, and 19 were originally included in this appeal but have been withdrawn and will not be considered.

Claims 1, 3, 6, 7, and 24 are representative of the appealed claims and read:

“1. A method of wrapping biscuit which comprises continuously advancing a column of biscuit stacked on edge, metering predetermined quantities of said moving column of biscuit, separating said predetermined quantities of biscuit into spaced packageable groups, conjointly advancing a continuous web of flexible wrapping material lengthwise adjacent said separated columnar groups of biscuit and progressively folding said web of wrapping material about said groups, folding and sealing the free edges of said wrapper in overlapping relationship about the advancing groups of biscuit thus forming a continuous wrapping around the spaced groups of biscuit, and collapsing and sealing said wrapper intermediate said groups of biscuit by bringing opposed sides of said wrapping into contact with one another, thereby forming a series of interlinked successive packages.
“3. A method of packaging biscuit which comprises continuously folding a web of flexible packaging material about a continuously advancing column of unit groups of biscuit stacked on edge, heat sealing the longitudinal free edges of said web while it advances to form a wrapper confining the stacked groups of biscuit therein, and collapsing and heat sealing said wrapper intermediate said groups to form a chain of packaged biscuit.
"6. A method of wrapping biscuit which comprises continuously advancing a column of biscuit stacked on edge, separating predetermined quantities of said moving columns of biscuit into spaced apart packageable units, conjointly advancing a continuous web of wrapping material lengthwise adjacent said columnar units of biscuit and progressively folding said web initially about said columnar units in substantially channel shape becoming progressively rectangular in cross section with outurned [sic] marginal edges, progressively folding and heat sealing said marginal edges together adjacent to said biscuit, and collapsing and heat sealing said wrapper at said spaced apart points intermediate said unit quantities of biscuit by bringing opposed sides of said wrapping at said points into contact with one another while applying heat and pressure thereto, thereby forming a series of successive interlinked packages.
“7. In a method of continuously wrapping packageable quantities of stacked biscuit in heat sealable packaging material the steps comprising folding a web of said material in [180]*180substantially rectangular shape about said biscuit with the marginal edge portions of said web placed together and forming a lip extending outwardly from the biscuit, progressively from end to end forming said lip into a V-shaped fold, applying heat to said fold to effect hermetic sealing thereof, and then cooling and flattening said fold against the side of said wrapper to form a longitudinal seam.
“24. Steps in a method of packaging biscuit, consisting in continuously feeding a web of packaging material in a horizontal direction, conveying a column of edgewise-stacked biscuit from a point remote from said packaging material, metering and segregating said biscuit into packageable groups, feeding said groups of biscuit parallel and contiguous with said packaging materials, and thereafter enveloping said packaging material around said groups of biscuit and sealing it while said groups are in motion.”

Appellant’s application discloses a process in which the “biscuits,” hereinafter referred to as biscuits or crackers, to be packaged are stacked on edge and in face to face contact with each other on a continuously moving horizontal convey- or belt. While the stacked crackers are in motion, predetermined numbers are successively separated from the forward end of the stack and moved forward in the form of blocks at a greater speed to a packaging device which surrounds them with a continuous web of flexible wrapping material which advances along with the biscuits and is progressively folded about them in the form of a tube. The longitudinal edges of the material are placed together to form a lip which is progressively formed into a V-shaped fold and heat-sealed. Thereafter the sections of the tube between the spaced blocks of biscuits are collapsed, heat-sealed, and severed, resulting in individually wrapped packages of biscuits.

The Denison patent, the basic reference, discloses a method of packaging articles such as blocks of oleomargarine or boxes of candy in which the articles are deposited in spaced relation on a continuously moving web of packaging material. As the web advances it folds about the articles in a tubular form, and the longitudinal edges are heat-sealed together, after which the sections of the tube intermediate the articles are pressed together, heat-sealed, then severed, also resulting in individual packages.

Appellant urges in his brief here that the Denison patent does not disclose an operative apparatus, particularly with respect to the folding and advancing of the web. So far as the record shows, that argument was not advanced before or considered by the Patent Office and is not stated in the reasons of appeal. Accordingly, it is not properly before us. In re Davis, 103 F.2d 922, 26 CCPA 1249; In re Goldberg, 168 F.2d 527, 35 CCPA 1225.

Moreover, while Denison does not show all the details of his apparatus, it is clear how it is intended to operate and, in our opinion, the elements not shown could readily be supplied by a person skilled in the art. Even if that could not be done, Denison’s web could easily be advanced and formed by hand.

The Smith et al., Prouty et al., and Monaco patents were cited as showing it to be old to stack crackers or biscuits on edge and to move the stack horizontally. [181]*181However, those patents do not show separation or packaging of the articles.

It was the opinion of the board that Denison’s process is applicable generally to the wrapping of blocks of any material which will maintain its shape while being wrapped, and that it would be obvious to apply the instant process to blocks of biscuits stacked on edge. We agree with the board

Denison’s packaging process is clearly independent of the specific nature of the blocks being wrapped and could be easily applied if so desired to blocks of biscuits stacked on edge. If the biscuits were of such a shape that they tended to fall over it would be obvious to restrain them by tying or some other suitable manner.
