Opinion

CLIFFE, District Judge.

The bill of complaint in this case was filed February 7, 1924, and is a suit in equity for infringement or threatened infringement of letters patent of the United States No. 1,090,776, granted to'Harrison H. Boyce March 17, 1914, for indicating system and apparatus for internal combustion engines.

The bill avers that prior to January 3, 1913, Harrison H. Boyce was the inventor of the invention described in the letters patent hereinabove mentioned; that he applied for letters patent for said invention, and the letters patent thereunder issued bear date March 17,1914, and are numbered 1,090,776; that said Boyce* as the original inventor of said patented device, sold to George H. Townsend, II, the exclusive license to make, use, and sell said invention throughout the United States, by the terms of which license said Townsend had the right to assign the same to a corporation to be organized by him; that the said Townsend, in the exercise of said right, thereafter caused to be organized the Moto Meter Company, Incorporated, plaintiff herein, of which said company the said Townsend is president, which company engaged in the manufacture and sale of the invention of the patent in suit, pursuant to the terms of said license, so assigned by said Townsend, and is still so engaged therein. The said plaintiff Moto Meter Company contends that it has duly marked all devices, manufactured and sold by it in accordance with said letters patent 1,090,776, “Patented March 17,1914,” and complied with the statute in specifically notifying the defendants of the existence thereof.

It is further averred that the defendants herein are related corporations, having some common officers, and that the defendant Semaphorie Indicator Sales Company acts as sales representative for the defendant Semaphorio Indicator .Company in the sale of the alleged infringing devices manufactured by the last-named defendant. This action is based on claims 1 to 5, inclusive, of the patent in suit, as follows:

“1. In a system for indicating abnormal conditions in an internal combustion engine having a liquid circulation cooling system for the cylinders of the engine, the combination with means forming an inclosed space above the level of the circulating liquid, of an indicating device having a temperature responsive element normally permanently so located with reference to said inclosing means as to respond to temperature changes in said inclosed space and means controlled by said element for giving a temperature change indication outside said space.
“2. In a system for indicating abnormal conditions in an internal combustion engine provided with a liquid circulation cooling system for the cylinders of the engine, said cooling system including a radiator having an air space at the top thereof, the combination with the radiator of an indicating device having an indicating part outside the radiator and having a temperature responsive element controlling the operation of said indicating part and exposed to the temperatura in said air space above the level of the liquid in the radiator and means for maintaining the temperature responsive element in place in the radiator during the normal operation of the engine.
“3. In a system for indicating abnormal conditions in an internal combustion engine provided with a liquid circulation cooling system for the cylinders of the engine, said cooling system including a radiator having an air space therein above the level of the circulating liquid and having a filler opening closed by a cap, the combination with the radiator and cap of an indicating device normally permanently mounted on said cap and having a normally visible indicating part and a temperature responsive element controlling the operation of said indicating part and exposed to temperatures within the air space.
“4. In a system for indicating abnormal conditions in an internal combustion engine provided with a liquid circulation cooling system for the cylinders of the engine, said cooling system including a radiator having an air space therein above the level of the circulating liquid, the combination with the [249]*249radiator of an indicating device normally permanently carried by said radiator and comprising an' exposed protective easing, a visible indicating part in said easing, and a temperature responsive element controlling the operation of said indicating part and normally located in the air space in the radiator.
“5. In a system for indicating abnormal conditions in an internal combustion engine provided with a liquid circulation cooling system for the cylinders of the engine, said cooling system including a radiator having an air space therein above the level of the circulating liquid and having a filler opening closed by a cap, the combination with the radiator and cap of an indicating device normally permanently attached to said cap and comprising an exposed protective casing, an indicating part in said easing and a temperature responsive element controlling the operation of said indicating part and normally located in the air space in said radiator.”

Several defenses are made, and a counterclaim asking for certain relief, and answer thereto, have been filed herein. Defendants set up that the said patent 1,090,776 is invalid, and raise the defense or defenses of prior uses, prior knowledge, prior printed publications, and prior patents.

The plaintiffs refer to the case of Boyce v. Stewart-Warner Speedometer Corporation, Circuit Court of Appeals, Second Circuit, decided December 15, 1914, reported in a 220 P. 118, in which the court had before it an order entered by the District Court of the United States for the Southern District of New York, granting a preliminary injunction restraining defendant therein ¿rom an alleged threatened infringement of the patent involved in this suit, and the court in its opinion, after referring to the objections to the invention as set forth in the specifications in the patent, says:

“The complainant’s device embodies the idea primarily of affording protection against the great evil of engine overheating, for which previously there had existed no remedy. It also provides an indication to the operator of the thermal condition of his engine. Both of these results are accomplished by the use of a temperature responsive device located in the air space at the top of the radiator of the engine cooling system. * * * This indication is not of exact water temperatures, but shows changes in thermal condition. When the point of danger is reached and steam is formed in the radiator, the instrument affords an unmistakable trouble signal. This is due to the peculiar organization of the apparatus whereby the temperature responsive element or thermometer normally indicates a lower, but substantially proportional, temperature with relation to the water temperature which jumps to the actual temperature upon the occurrence of dangerous conditions.”
The device referred to by the court in that case was called the Stewart radiator meter, which the court stated is an instrument of exactly the same characteristics as the Boyce motometer, the patent in suit here. The court says further (page 120): “Like the Boyce motometer, it is designed to be attached to the radiator cap of an automobile, and it has an indicator which provides temperature readings visible from the driver’s seat.
