Opinion

THACHER, District Judge

(after stating the facts as above). In a suit upon a reissued patent it is a good defense to show from the Patent Office record that there was no inadvertence, accident, or mistake in drawing the specification and claims of the original patent, for the statute (R. S. § "4916 [35 USCA § 64]) only authorizes reissue when the original is defective by inadvertence, accident, or mistake. Mahn v. Harwood, 112 U. S. 354, 5 S. Ct. 174, 28 L. Ed. 665. From the record the following appears:

Original application was filed June 29, 1906. All of the claims were rejected on reference to two patents issued to Just — No. 712,545, November 4, 1902, and No. 764,294 on July 5, 1904. In response to this action the patentee requested reconsideration, endeavoring to distinguish his process from that disclosed in the Just patents. Thereafter the Examiner held the claims too indefinite to avoid the references, and suggested amendment. The patentee then requested cancellation of all pending claims and the substitution of seven new claims. The third of these claims reads as follows; “3. The hereinbe-fore described process of obtaining pure dry milk solids of practically natural solubility, in light flaky form, from pure fresh liquid milk of natural acidity, which consists in exposing such milk, in a very thin uniform film, during less than two and one-half seconds of [920]*920time, upon a suitable drying surface heated to a temperature slightly higher than the temperature necessary, under any given condition of atmospheric pressure to evaporate the water contained in the said film and reduce its solids to a dry preservable state within the extremely limited time of exposure specified.”

All of the new claims were rejected December 28, 1907, on the same references, but the Examiner concluded his communication as follows: “ * * * To assist applicant in further prosecution, it is noted that the claims are now in good form and on request for reconsideration under Rule 69 the action on the merits will be made final, whereupon appeal may be had under Rule 133.”

In the- Just patent, No. 712,545, it was stated that the temperature of the drying surfaces should not exceed 270°Fahrenheit. After careful consideration of the Patent Office communication of December 28, 1907, for almost a year, the patentee advised the Patent Office of his decision to accept the rejection of his claims and to propose new ones limited to'the use of temperatures in excess of 270° Fahrenheit. In his communication to the Patent Office* under date of December 12, 1908, he said:

“I have carefully considered the communication of the Examiner of December 28, 1907, and reconsidered all former objections and now wish greatly to limit my invention. I beg, therefore, that the title may be changed to Improvements in Drying Milk, and that the specification and claims may be amended, as per the enclosed copy.
“I see that my specification as originally drawn was too broad and I now limit it to the drying of milk and mixtures of milk and other substances.
“I also abandon all claim to drying in vac-uo, and limit myself to the use of a drying surface heated in excess of .270° F.
“This last limitation places me clearly outside of the Just specification so far as temperature is concerned for he expressly states (lines 83 and 84 of page 2 of Patent 712,545) that the drying surface must not exceed 270° F. as a maximum.
“My use of a temperature higher than his maximum, my extremely limited exposure and the further important faet that I obtain by this new process dry milk of absolute purity and of greatly improved quality, give me, I think, a perfect right to the new claims I now present.”

Four claims.were proposed. .Two on'the process were allowed, and now appear as claims 1 and 2 of both the original and the reissue patent as quoted above. Two others on the product were rejected. In due course the original patent issued accordingly.

On August 18, 1910, fifteen months after issue of the original patent, application was made for reissue upon the ground that the patentee had inadvertently failed to. claim all that he was entitled to claim under his original specification. The reissue claims 3, 4, and 5 eventuated upon this application, and their validity upon reissue is questioned. The application for reissue was examined by an Examiner not employed in the examination of the original application, and was at first denied, but later granted upon consideration of an extensive argument presented by attorneys for the patentee. This argument the patentee has since seen fit to repudiate in litigation in which he was engaged in England as a licensee under the British patent to Just. It also appears that the Examiner did not note the equivalence between claim 4, allowed on reissue, and claim. 3, rejected by the Patent Office ruling of December 28,1907, in which rejection Hatmaker acquiesced as shown by his letter of December 12, 1908, quoted above. The Examiner allowed claim 4 only because he considered 'that the insertion of the words “with its aeid unneutralized and free from added chemical agents” distinguished it from claims rejected upon the original application. But these words mean nothing more nor less than the phrase “from pure, fresh liquid milk of natural acidity,”. which appear in claim 3 rejected on December 28, 1907, quoted above. Of course, the addition of the phrase “and forcing said film from said surface” cannot differentiate the two claims, because under each it was necessary to remove the film of milk from the surface within the extremely short period of two and one-half seconds. Comparison shows identity of subject-matter between the rejected claim 3 and the reissue claim 4.

What is abandoned by acceptance of'a patent after acquiescence in the rejection or limitation of a claim cannot be recaptured upon reissue. Powder Co. v. Powder Works, 98 U. S. 126, 138, 25 L. Ed. 77; Leggett v. Avery, 101 U. S. 256,. 25 L. Ed. 865; Dobson v. Lees, 137 U. S. 258, 11 S. Ct. 71, 34 L. Ed. 652; Corbin Lock Co. v. Eagle Lock Co., 150 U. S. 38, 43, 14 S. Ct. 28, 37 L. Ed. 989; Yale Lock Co. v. Berkshire Bank, 135 U. S. 342, 379, 10 S. Ct. 884. See Morey v. Lockwood, 8 Wall. (75 U. S.) 230, 19 L. Ed. 339, cited infra. Except under very unusual circumstances (See Morey v. Lockwood, 8 Wall. [75 U. S.] 230, 19 L. Ed. 339, cited infra) the statute (R. S. § 4916) can have no application to such a case, [921]*921because it only permits reissue when the original patent is defective “by inadvertence, accident, or mistake” — terms which do not comprehend the proposal of a claim by the patentee, its consideration and rejection by the Examiner, and acquiescence in the. ruling by the patentee. Obviously the statute does not mean by “inadvertence, accident, or mistake” errors in rulings deliberately made by the Examiner and quite as deliberately accepted by the patentee.
