Opinion

SANBORN, District Judge.

Infringement suit on two patents issued to Edwin F. Guth, with a second claim for unfair competition; the parties being citizens of different states, and $5,000 damages claimed. The patents involved are for an improved electric lamp for semi-indirect illumination, called the Braskolite, and are numbered 1,076,418 and 1,082,322. Defendant’s lamp is known as the “400 Unit.”

[1] The two important questions are the validity of tile first patent and the alleged unfair competition, since there is very little difference between the Braskolite and the 400 Unit. These fixtures seem to have taken their final form, and that form was reached by the Braskolite, as shown in the patent. It has not been improved on, although the most [266]*266persistent effort to do this has been made. Mr. Verhunce, defendant’s manager, thus testified on the point:

“Q. This all tends to show that the Braskolite pretty nearly hit the middle of the hull’s eye, doesn’t it? A. I do not think there is much doubt about it. They have got the cheapest form of production that could be devised. Q. Like the rubber-tired wheel, it cannot be improved on. A. You could not make it much different from that form, without making it cost more, or detracting from its appearance, or otherwise making it inferior.”

It is upon this basis that defendant claims there cannot be any decree for unfair competition under the rule of the vacuum cleaner decision, cited later. The lamp called the Braskolite, made under the earlier patent, is indeed a very beautiful one, of very high efficiency. It consists of a circular canopy about 16 inches in diameter, with a plain, flat white lower surface for better reflection, and an electric lamp in a suspended, inverted glass bowl just below it, and is described by Professor Mohr as follows:

“It consists of a reflector, or a canopy especially designed to act as a reflector, and luminous bowl in relative position, and a depending lighting fixture lamp, depending down into the bowl, into the luminous bowl, all three of which elements forming to make a symmetrical relative connection between those three, governing the light so as to throw it down into a useful plane.”
“It has a decided advantage, one that I immediately recognized as a competitor. It has a perfect diffusion in so far as the useful area is concerned, and that is what we illuminating engineers are striving for. It accomplishes what -no other unit previous to it had accomplished. It acted both as a quality — I mean by that the quality of light was of such a nature, due to the fact none of the rays as they came out of that bowl, as reflected to the upper reflector and back into the room, came in contact with anything that might absorb the spectrum of the original lamp rays, or the rays. It therefore always was a white light on the working plane.”

Plaintiff’s counsel also examined a large number of managers of lighting fixture houses, in some 18 states. Their almost uniform testimony was that the impression made on them by the Braskolite was that it was something entirely new, absolutely new, a new departure in lighting fixtures, making a large saving in current, better diffusion, very efficient, “the greatest light giver of any fixture within my knowledge,” furnishing an ideal and perfect ceiling as a reflecting surface, a simple and original- conception.

Claim 2 of the first patent reads:

“In a lighting fixture, the combination, with suitable ceiling connections, of a lamp socket attached thereto, a canopy covering said ceiling connections and lamp -socket, said canopy having a wholly flat lower surface adapted to reflect light, a translucent light diffusing bowl positioned below and opening toward the central portion of the flat reflecting surface, the area of the bowl opening being less than that of the said reflecting surface, a lamp in the lamp receptacle and extending into the bowl, means for suspending the bowl so that light passing downwardly through it will be unobstructed, the bowl, lamp, and reflecting surface being positioned with relation to each other to cause substantially all the rays of light from the lamp to be directed downwardly and distributed in a diffused condition over the entire surface of a horizontal plane beneath the fixture and of greater reflecting area than the reflecting member.”

Of course, the inventive notion must “emerge from the description,” as Judge Grosscup said in State Bank of Chicago v. Hillman, 180 Fed. [267]*267732, 104 C. C. A. 98, and the point is made by defendant’s counsel that the patent does not call for a white reflecting surface, but for “an opaque or translucent glass canopy.” However, the inventor clearly, intended that the canopy should reflect all the rays coming from the lamp to the under surface of the canopy. He says that part of them will go through the bowl, and that practically all the rays are brought to the working plane (the “useful plane”), instead of directing them or permitting a large portion to pass to the ceiling, to be reflected tlicnce to the working plane. The “principle of the invention” clearly requires an opaque reflecting surface, so that the claims, where they say that substantially all the rays are to be directed downwardly, do not go beyond the description.

It is true, and without dispute in the evidence, that all the elements of this combination are old. The broad idea of a semi-indirect lighting fixture, with an overhead reflector and a translucent bowl in spaced relation to a reflector, and containing a lamp arranged within the bowl, was old. This is shown by the prior art on paper, and by the Bredsvold fixture in evidence. But this fact is not decisive on the question of validity, because this combination was new, and produces a new and most useful result, never before obtained in any of the prior art structures. It is indeed narrow, but defendant is at liberty to use Bredsvold, or any other prior fixture, instead of taking the Braskolite with almost exact imitation.

One of the witnesses says that he attributes the increased efficiency of tlie Braskolite over the other fixtures—

‘1;o tlie Judicious construction of the same in permitting part of tlie light of tlie incandescent lamp to radiate unobstructedly in the plane of the artificial ceiling reflector, where it is most desirable that this should be so, and in breaking up the downward rays through the bowl in such a manner as to obtain illumination of substantially equal intensity in approximately horizontal plane from the plane of vision, and a construct ion by which the relative position of a source of light to the glass globe and reflector was always insured to be the proper one to obtain the maximum of results.”

It is also a unitary structure, in the sense that it may be hung in any position without any modification due to its surroundings. It fits in anywhere, and produces substantially the same beneficial result in any position. The first patent should be sustained, not broadly, but as a meritorious and successful combination, with a beneficial result, unless it was anticipated by the prior patents and publications in evidence, or by the Bredsvold fixture.

A number of prior patents were discussed by Mr. McElroy for defendant and Prof. Mohr for plaintiff in reply. They all resemble the Braskolite in some respects, but none of them is a clear anticipation.
