Opinion
The invention is a parking lamp for automobiles. It is smaller, neater in appearance, and more firmly attachable to a machine, than those which had been theretofore used. So soon as it was put upon the market, there was a large demand for it. The defendant bought some of plaintiff’s lamps, borrowed some of the parts of them from plaintiff, and proceeded to design and manufacture a lamp obviously modeled upon that of plaintiff’s. He, of course, made some changes which he hoped were sufficient to escape infringement, and,so far as two out of three of plaintiff’s patent claims are concerned he admittedly succeeded.
There is only one claim in suit, the third. It is quite long, having something like a dozen elements, most of them being concerned with rather minute matters of mechanical detail. There is no reason to [847]*847suppose that any one before plaintiff had ever made just such a lamp as this claim describes, but there is great difficulty in finding out in what plaintiff’s invention consists. He wanted to make a lamp of small size, which would do the work as well as the larger lamps which had been theretofore used. This part of his purpose he accomplished by using multifaceted lenses, but the use of such lenses for such purposes had long been known. He wished to make it possible easily to open his lamp and replace an electric bulb, which was defective or worn out, and he provided means for doing so that had often been theretofore used for analogous purposes. He desired to secure the lamp to the fender, so that it could not be readily jostled off. This he did by the use of appliances long known in the art.
It is with some regret that I am compelled to hold the claim in suit invalid, and to dismiss the bill, as it would seem to be clear enough that, if plaintiff has invented anything, defendant has used it.
