No. 173 | 2d Cir. | Apr 14, 1920
(after stating the facts as above).
In 1901, so far as this record reveals facts, Brinkman was the first to make or propose to make a radiator suited for the hard service of a motor car out of thin sheet metal, using the corrugations thereof, connected or slightly separated as desired, to' form tubes or passages for both air and water, and to obtain by attaching one corrugation to another and indefinitely repeating the conjunction a structure of any desired size that may almost be called integral and is both strong and light. The rank of an invention often depends on the nature or extent of the art which may be invoked to explain or limit it. Corrugated sheet metal had been used to facilitate the condensation of steam (Ujungstrom, No. 574,157), and that art may be admitted as cognate; but Brinkman first made the honeycomb radiator of an automobile, and he therefore stands “at the head of a class [and] is entitled to a liberal range of equivalents” (Lamson, etc., Co. v. Hillman, 123 Fed. 423, 59 C. C. A. 517), unless defeated by some weakness other than the nature of his inventive thought.
The only prior art worthy of mention is Maybach, whose several foreign patents are earlier than his United States patent No. 709,416. That device may be described, in words largely taken from specifications, as a means of determining and maintaining a spaced arrangement of pre-existing tubes; the air going through the tubes and the water through the, spaces. It may be as good a radiator as that described in the patent in suit, hut to us it does not even suggest the “honeycomb” construction.
■ Such limitation is asserted, /because the first and second claims specifically define the “refrigerating section” of the cooler as “consisting of a continuous strip of corrugated sheet metal”; and the specification tells at considerable length how the sheet can be doubled upon itself and the operation repeated. If the radiator of a large truck were thus fabricated, it would require a metal strip 550 feet long, and Brinkman never made his machines in that way; he has always taken strips of convenient length and soldered them together when in place, and so does the defendant.
Thus the final question is whether the unfortunate phrase, “continuous strip” of metal, puts claims 1 and 2 in the list of “patents * * * couched in language so plain and unambiguous as to leave no room for construction.” Ryan v. Metropolitan, etc., Club, 144 Fed. 699, 75 C. C. A. 515. We think not; and as matter of verbal interpretation we agree with Coxe, J. (Brown v. Reed Mfg. Co. [C. C.] 81 F. 48" court="None" date_filed="1897-06-05" href="https://app.midpage.ai/document/brown-v-reed-manufg-co-8859020?utm_source=webapp" opinion_id="8859020">81 Fed. 48; appeal dismissed 96 F. 1005" court="1st Cir." date_filed="1899-10-04" href="https://app.midpage.ai/document/hart--hegeman-mfg-co-v-anchor-electric-co-8866412?utm_source=webapp" opinion_id="8866412">96 Fed. 1005, 37 C.C.A. 665" court="1st Cir." date_filed="1899-10-10" href="https://app.midpage.ai/document/third-nat-bank-v-merchants-nat-bank-8866420?utm_source=webapp" opinion_id="8866420">37 C. C. A. 665), that “continuous” may and here should be taken in a mechanical sense; and two pieces of metal contiguously placed and soldered together may he considered as a continuous piece when together they function like one piece.
Acceptance of this signification for “continuous” renders it unnecessary to inquire along somewhat broader lines whether, considering that generic inventions in their first embodiments frequently work imperfectly, Brinkman’s severing of metal sheets was more than that “mere readjustment” thought immaterial by this court in Scott v. Fisher Co., 145 Fed. 922, 76 C.C.A. 447" court="2d Cir." date_filed="1906-05-22" href="https://app.midpage.ai/document/scott-v-fisher-knitting-mach-co-8760865?utm_source=webapp" opinion_id="8760865">76 C. C. A. 447, or whether defendant has “used the idea of the patent modified only in respects which the paten-tee left open for modification.” Van Kannel, etc., Co. v. Straus, 235 Fed. 137, 148 C. C. A. 631. It also avoids consideration of the third claim.
Decree reversed, with costs, and the cause remanded, with directions to sustain the claims in suit and grant the usual interlocutory decree.
This ruling was long ago made by Blatchford, .T., in Masury v. Anderson, 11 Blatchf. 105, Led. Cas. No. 9,270. He added that if, while operating under his patent, the patentee “at one time insists on too much, or at another on too nttle, he does not thereby work any prejudice to the rights actually secured” to him by his patent.
We have not overlooked Brinkman's later patent, No. 779,581, but think it relates to a different type of radiator, and that it contains no language inconsistent with plaintiff’s position as to the patent in suit.
