Opinion

Hatfield, 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 rejecting claims 1, 2, 5, and 15 to 18, inclusive, in appel[1071]*1071lant’s application for a patent for an alleged invention relating to a method of coring half pears, as defined in claims 1, 2, and 5, and to the product of such method, as defined in claims 15 to 18, inclusive.

Eleven process claims were allowed by the Primary Examiner.

Claims 1, 2, and 15 are illustrative of the appealed claims. They read:

1. The method of coring- half iDears which comxn-ises apiDlying to the cut surface of the half pear a continuous cutting edge of a configuration conforming to the longitudinal configuration of the seed-containing and stem thread portions •of the half pear, moving the cutting edge relative to the half x>ear along a semicircular path substantially about a stationary axis substantially.coinciding witli the stem axis of the half pear whereby simultaneously to sever the seed-containing portion and relatively tough stem threads from the meat of the liear and whereby to form a continuous channel of semicircular cross section in a direction transverse to the stem axis and coextensive in length with the seed-containing and stem thread portions of the. half pear and substantially concentric with such stem axis.
2. A method of coring half pears having a calyx, a core proper, and a stem thread section extending from the core proper to the stem end, which comprises forming a single continuous cut of varying depth from end io end of the half pear uyhich is truly semicircular and which is formed substantially concentrically to the stem axis of the half pear whereby simultaneously to sever the calyx, the core proper and the stem thread section from the half pear with a cut of minimum width between the portion from which the calyx was removed and the portion from which the core proper was removed. [Italics ours.]
15. A cored half pear having a single, continuous groove of varying longitudinal configuration and formed substantially concentrically with respect to the stem axis of the half pear, said groove being formed semieylindrieal in cross section at every point along the stem axis of the half pear and extending substantially from end to one! of the half pear, portions of said groove closely conforming in shape to the shape of the calyx, the core proper, and the stem thread sections of the uncored half pear, and said groove having a restricted portion or throat connecting the calyx conforming ]?ortion of the groove to the portion of the groove conforming to the core proper.

The references are:

Swett el al., 95,286, September 28, 1869.
Spencer et al., 1,769,654, July 1, 1930.

Appellant disclosed in his application an apparatus for carrying out the method defined in appealed claims 1, 2 and 5, and for producing, by his claimed method, the article defined in appealed claims 15 to 18, inclusive.

Both appellant’s method and the article produced thereby are sufficiently defined in the quoted claims.

The patent to Swett et al. relates to an improved apple-corer, and discloses a hand-operated apple-corer comprising a rod, which is adapted to be pressed against the half-section of an apple, and a cutting knife attached to the rod. The blade of the knife has a curved portion intermediate its two ends and is designed, as stated [1072]*1072by the patentees, to cut out the seed-lobe and the stem and the blossom end in one operation.' The patentees state that in the operation of their device “the half apple- is grasped in one hand and the corer in the other,” and the corer is then placed “on the apple in such a position that the rod” to which the knife blade is attached “will be directly over the centre. Now if the rod be firmly pressed on to the apple, and at the same time revolved, the knife DEF will cut entirely around all parts of the core and thus remove it.”

The patent to Spencer et al. relates to an invention for paring and coring half pears. According to the patentees’ disclosure, half pears are placed in cups and the peel and core removed by knives shaped for that purpose.

Appealed claims 1, 2, and 5 were rejected by the Primary Examiner on the. ground that each of the references anticipated the method defined by those claims.- Claims 15 to 18, inclusive, were rejected by the examiner—

* .* * as being for an article which does not come under any of the statutory classes of invention, not being for an art, machine, manufacture or composition of matter, nor for any new and useful improvement thereof.
* * * * * * *
A half pear with its core, stem, and calyx removed is still a natural pear and not a manufacture, the result of invention.

In support of his views, the examiner cited the case of American Fruit Growers Inc. v. Brogdex Co., 288 U. S. 1.

In affirming the decision of the Primary Examiner, the Board of Appeals stated that the jiatent to Swett et al.—

* * * discloses an apple-corer which makes a cut extending the full length of the half fruit. It makes a cut which is substantially semicircular in cross section at all points of the core axis. The drawing shows the bar BO, which is described as being rounded, initially positioned at one side of the core amis. In making the cut it rolls over to the other side of the core axis, so the cut is not displaced as illustrated in Sheet 1 of the drawings accompanying the applicant’s drief. No part of the cut has greater width than that part between the blossom end and the core proper. The method is not patentably different because it is performed on a half pear, instead of on a half apple as in the patent. These three claims [Nos. 1, 2, and 5] are considered not allowable over this patent. [Italics ours.]

The board also -held that appealed claims 1 and 5 were substantially anticipated by the patent to Spencer et al. Apparently in answer to the contention of counsel for appellant that the patent to Spencer et al. did not disclose an operative structure or one which could be made operative by one possessing ordinary mechanical skill, the board said:

It is true the knife blade 41 should be below instead of above the axis of rotation when viewed as shown in Fig. 9 of the patent. Otherwise, it could not make the cut attributed to it in the patent. One making the cutter of the patent would [1073]*1073•certainly so position the blade 41 with respect to the axis of rotation that it would make the cut described in the patent.

The board also held that as claims 15 to 18, inclusive, defined a cored half pear which “is still in its natural state,” the examiner was right in rejecting them as not being for patentable subject matter.

On January 29,1942, subsequent to the oral arguments in this court, ■counsel for appellant submitted to the court the following typewritten statement:

On behalf of appellant, it is conceded that Claims 1 and 5 read on the patent to Spencer et' al. No.
