Opinion

R. DORSEY WATKINS, District Judge.

This is an action for alleged patent infringement, unfair competition and trademark infringement, brought by the inventor and his exclusive licensee. During the trial, the claims for unfair competition and trademark infringement were dismissed with prejudice1

Defendants moved for summary judgment on the pleadings together with patent No. 597,402, issued to E. H. Duche[163] min, filed with the motion. The motion was overruled after hearing in open court.2

Thereafter an amended complaint was filed. Defendants filed the usual answer, denying the allegations of validity of the patent in suit on the ground of the prior art, disclosures in patents and printed publications, prior knowledge and use, defects in the claims, and misuse of the patent. Defendants also counterclaimed for a declaratory judgment that the patent in suit was invalid and not infringed.3 A second amended complaint was filed to add a new party defendant.

The patent in suit (S. M. Collins, 2,-667,218 filed February 1, 1952, issued January 26, 1954) is for a “folding closure”. Its object was to provide an attractive-looking folding door which could be easily installed in a household opening without special hardware and which could be manufactured of easily available materials to provide an inexpensive but attractive hingeless door closure. These ends 4 are attained by the product manufactured by the corporate plaintiff under the patent.

The specifications state:

“Briefly, the invention consists ■of double sheets of decorative material such as leather, plastic or fabric which are sewed into vertical pockets, closed at the top, and in which is inserted a stiffening panel of inexpensive material provided with a ■supporting device which projects through the top of the pockets to co-operate with a slide.”

The claims to which the proceedings were directed are 8, 9 and 10, reading as follows:

“8. A foldable closure for doorways which comprises a plurality of thin, fiat, elongate panels adapted to form a door when in aligned position, separate supporting means at the top of each panel centrally thereof, a track for slidably mounting said supporting means at the top of a door opening, and an ornamental sheathing for said panels covering each side and joined between said panels to space the panels and b&ing flexible to form with the panels a hinged series of panels positionable at will in closely spaced, parallel relation or in aligned relation, the joined portions of the sheathing forming the sole hinge between the panels.
“9. A combination as defined in claim 8 in which the sheathing is closed at the top to receive its sole support from the top edges of said panels.
“10. A combination as defined in claim 9 in which the sheathing is open at the bottom to permit the removal and replacement of individual panels.”

At the trial, defendants admitted infringement if plaintiff’s patent were held valid.

The defenses relied upon were (1) anticipation by prior patents; (2) pri- or knowledge and use; and (3) lack of patentable invention.

1. Prior Patents.

The device disclosed by the specifications and drawings, and claimed in Claim 10 (in combination with claims 8 and 9) [164] may be summarized as comprised of 5 (a) double sheets of decorative material, (b) (1) which are sewed into vertical pockets, closed at the top and (2) open at the bottom to permit removal and replacement of panels; and (c) in which is inserted a stiffening panel, (d) provided with a supporting device which projects through the top of the pockets to cooperate with a slide, (e) the joined portions of the sheathing forming the sole hinge between the panels.

By way of patent anticipation, defendants offered in evidence copies of the following patents:

The wide range of the cited patented devices makes it impractical, within any reasonable space, to analyze each one separately as it may apply to the five features of the device in question. Each was discussed by the witnesses and counsel as it was introduced, was dealt with in oral argument at the conclusion of the case and in briefs subsequently filed, and was considered by the Court, both during the trial, and in the light of the arguments and the briefs. I find as a fact and conclude as a matter of law that with respect to the above-mentioned five constituents of the device, the use of: (a) double sheets of decorative material is anticipated by Holtzclaw, Cone, Brokering and Nordell; (c) a stiffening panel inserted in pockets is anticipated by Holtzclaw, Duchemin, Simmons, Kaplan, Cone, Kwon, Brokering and Wirthman; (d) a panel-supporting device which projects through the top of the pockets to cooperate with a slide is anticipated by Holtzclaw, Parker, Burford, Applas, Byron and Kwon; and (e) joined portions of panel sheathing forming the sole hinge between the panels is anticipated by Holtzclaw, Duchemin, Cone, Brokering and Wirthman.

The cited patents disclose suspended slats, permanently hinged; slats of varying lengths permanently and independently enclosed in material, and permanently hinged; and slats of varying length sewn into closed pockets. None of them shows separately, and none suggests, a combination of individually suspended and unjoined panels covered by a vertically pocketed cover closed at the top and open at the bottom, as is [165] disclosed in the patent in .suit, whereby the panels serve the dual function of stiffening the cover, and in addition to supporting the cover generally, do so- in a way preventing sag; and the cover performs the dual function of a cover and a hinge; the result being a suspended accordion folding door.6
