Decided 1935-01-24

¶1*933Samuel W. Banning, of Chicago, 111. (Henry B. Floyd, of Chicago, 111., of counsel), for appellants.

¶2William A. Bither and Luella M. Bither, both of Chicago, 111., for appellee Nick Thomas.

¶3Before ALSCHULER, EVANS, and FITZHENRY, Circuit Judges.

¶4ALSCHULER, Circuit Judge.

¶5The bill charged infringement of United States Patent No. 1,370,913, March 8, 1921, for a “Composition of Matter for Doughnut Mix.” Upon the hearing the District Court held the patent void for want of invention and for anticipation, and dismissed the bill for want of equity. The quite brief specification1 concludes with this single claim:

“I claim: A semi-liquid composition of matter consisting of milk and flour, with the other ingredients necessary to a doughnut, in such proportions that due to the amount of milk present, the mix is capable of being- poured into hot grease to form a doughnut.”

¶6However detailedly the specification sets forth the ingredients of a doughnut mix and describes the somewhat complicated process of bringing together the enumerated ingredients and then cooking them, it is plain from the file wrapper that the Patent Office did not intend to confer a monopoly for employing the ingredients composing the mix, nor for the process of mixing the ingredients and producing doughnuts ; and from the claim itself it is equally clear that the granted monopoly did not extend to a process for making doughnuts, nor for doughnuts composed of the enumerated ingredients.

¶7It is equally plain that the patent does not cover mechanism of any kind for the production of doughnuts from any sort of mix. The essence of the claim seems to lie in the inclusion in any mix of enough milk to render the mix sufficiently fluid for pouring, and this quite regardless of whether the mix flows automatically from a hopper into a machine or is poured by hand from a pitcher or other receptacle into a doughnut form, and thence into hot grease for cooking.

¶8The only advance which the patent purports to claim is in the fluidity of the mix *934due to the milk content. In other words, there is formed a batter which, after the manner of batters, is of such fluidity that it will pour by gravity. Webster defines batter as “a semiliquid mixture of several ingredients, as of flour, eggs, milk, etc., beaten together and used in cookery.” And who does not recall from earliest memory the various cakes and pastries produced from batters of different kinds and degrees, which were poured from spoons, ladles, pitchers and other containers, onto hot griddles or stove tops or waffle irons, or into greased skillets or hot deep fat?

¶9In our judgment the increase or decrease of the milk or other liquid content of a mixture for the sole purpose of producing or increasing or diminishing the fluidity of the mix so that it will flow more or less readily as may be .desired, does not attain unfo the dignity of invention.

¶10In the Examiner’s communications (see marginal note 2), his first and second rejections of the claim were, in our judgment, well grounded in his holding that the recipe disclosed did not involve invention, and that the ingredients were all well known. But, at any rate, the patentee acquiesced in the rejections, and predicated his final claim as allowed on the variation in proportion of a single ingredient (milk) instead of all of them. Surely if invention was not involved in the combining of all the enumerated ingredients, invention did not reside in the employment of one of them in combination with the others. We think this claim was improperly allowed.

¶11Whether the precise proportion of milk to the other ingredients of a doughnut mix as pointed out in the specification was employed prior to the invention date of the patent is not here material, where no claim is directed to a mix of those ingredients or to the proportions as set forth in the specification.

¶12From this record it is apparent to us that the court properly held the patent void and dismissed the bill for want of equity.

¶13The decree is affirmed.
