Opinion

MAHONEY, Circuit Judge.

The plaintiffs, The Anderson Company and Productive Inventions, Inc., Indiana corporations, brought suit in the district court for the infringement of three patents, namely: Nilson and Prince No. 1,597,999, hereinafter called the Nilson patent, Anderson No. 1,853,715 and Anderson No. 1,950,-588. The defendants, Lion Products Co., Inc., a Massachusetts corporation, and Max Zaiger, a resident of that state, pleaded the defenses of invalidity and non-infringement. The district court held the patents invalid for lack of invention, entered its judgment for the defendants and the plaintiffs have appealed. The plaintiffs have not in their briefs or in the oral argument before us pressed the appeal on the first two patents, and the appeal is now limited to the judgment in so far as it relates to patent No. 1,950,588. Without giving further consideration to them, we affirm the judgment of the district court on patents Nos. 1,597,-999 and 1,853,715.

The plaintiff, Productive Inventions, Inc., is the owner by assignment of patent No. 1,950,588 issued March 13, 1934 to John W. Anderson, and the plaintiff, the Anderson Company, has been since December 1, 1936, and now is the exclusive licensee of the plaintiff, Productive Inventions, Inc., under said patent.

The patent under consideration concerns a windshield wiper consisting of a U-shaped or channel holder with side portions bent or curved outwardly at the outer edges so that the open side of the holder is flared, an enlarged head of single ply, triangular in cross-section, with longitudinally extending arrises or sharp edges, and an integral flexible flange connecting the head portion with the holder. The specification states that this windshield wiper has both the advantages of a single ply and a multi-ply wiper and is particularly efficient under all weather and climatic conditions. It is asserted that water, moisture and snow do not get in and freeze as in the multi-ply heads, and dirt and other elements cannot penetrate between the plies and cause deterioration of the wiper element. It states that the wiper and holder are so constructed that the wiper element is at all times maintained in operative contact with the surface to be wiped and is so supported by the flared edge that it does not at any time lie flat with the glass but has a scraping or cleaning effect as it travels across the windshield.

All five claims are in issue and are as follows :

“1. In a device of the kind described and in combination, a wiper element and holder therefor, said wiper element consisting of an enlarged head portion provided with a flexible body arranged on the head and operating to connect the head to its holder, [456]*456said holder consisting of a channel-shaped element having its sides adjacent the closed end spaced a distance substantially equal to the thickness of the body of the wiper element, the outer free edges of the sides of the channel being outwardly flared, the wiper element being so disposed in its holder that a portion of the body constitutes a flexible hinge portion connecting the head and holder which may overlie and contact with the flared over edge of the adjacent channel side when the wiper element is flexed toward that side.
“2. In a device of the kind described and in combination, a single ply wiper element and holder therefor, said wiper element consisting of a head portion of triangular cross-section provided with a flexible body of less thickness than the width of the head portion extending from the base of the head and operative to connect the head to its holder, said holder consisting of a channel-shaped element having its sides adjacent the closed end spaced a distance substantially equal to the thickness of the body- of the wiper element, the outer free edges of the sides of the channel being outwardly flared, the wiper element being so disposed in its holder that the shoulders on the underside of the head lie adjacent the free edge of the adjacent channel side when the wiper element is flexed toward and into engagement with that side.
“3. A wiper blade comprising a head which is substantially triangular in cross section, the opposite sides of said head having longitudinally extending arrises, and an integral flexible body extending from the base of the head in a plane substantially perpendicular to said base.
“4. A wiper blade comprising a head which is substantially triangular in cross section, the opposite sides of said head having longitudinally extending arrises, an integral body extending from the base of the head and being positioned within the marginal edges of said base, said body being arranged in a plane substantially perpendicular to said base and being flexibly connected to said head.
“5. A windshield wiper blade comprising a head which is substantially triangular in cross-section, the opposite sides of said head having longitudinally extending arrises, and a body of relatively narrow cross-section connected to said head and extending from the base thereof between the lateral extremities of the head, said body being capable of yielding to permit the lateral movement of said head with relation to said body as the head is moved in opposite directions across the-surface of a windshield.”

The district court - held that the flared edges described in plaintiffs’ claims 1 and 2 were anticipated by the Nilson patent. In reaching the conclusion that the Nilson patent was invalid, reliance was placed upon the Lane patent No. 948,630 (a window cleaner and holder with a flared edge on one side)', Conant No. 1,062,322 (a window cleaner and holder with flared edges) and Green No. 1,397,511 (a windshield cleaner and holder with flared edges). We do not give great emphasis to the latter three patents but in so far as they refer to the flared edges they buttress the holding of invalidity of the claims now under consideration. An examination of the specification and the single claim of the Nilson patent discloses very clearly the idea of flared or curved edges. The improvement there described is the U-shaped holder with edges receding away from each other so that the flexible portion of the head and the curved edges of the holder come into gradual contact instead of the usual abrupt contact found in the operation of holders without flared edges. The same idea of curved edge or edges is found in the patents to which reference has been made. In all of these patents the purpose of the flared edges is to assure the gradual contact of the wiping portion and the holder.

It is strenuously urged by plaintiffs that the lower court failed to perceive the true nature of claims 1 and 2. They do not deny that the principle of flared edges is to be found in the Nilson patent. They contend, however, that what is new in claims 1 and 2 is not the flared edges per se but the cooperation between the flared edges and the enlarged head of triangular cross-section which permits a shoulder of the wiper element to rest against the flared edge of the holder, thus preventing too great a flexing of the head. This they say is a new function. The asserted advantage derived from the cooperation of the head and the flared edges is that the head is always maintained in a proper position, even under abnormal weather conditions, and that the head is more easily reversed on the return stroke of the wiper, with the result that a more efficient cleaning of the windshield is at all times assured.
