Opinion

SLICK, District Judge.

Suit for infringement on reissued patent, No. 19,469, granted to Christensen on brake mechanism for automobiles and similar vehicles February 19, 1935, on an application filed January 7, 1935. ’ The reissue was of original patent, No. 1,291,765, granted January 21, 1919, on an' application filed September 4, 1914.

The principal defenses claimed by defendant are:

1. Prior art anticipation.

2. That the claims of the reissued patent are for a different invention than that disclosed in the original patent.

3. Noninfringement.

4. Invalidity of the reissued patent because of noncompliance with the reissue statute and the rules and practice of the Patent Office.

5. Laches.

As in this opinion it is held that the reissued patent is invalid because it was issued for a different invention than that disclosed in the ' original patent, and did not comply with the requirements of the reissue statute and rules and practice of the Patent Office, and further that there is no infringement, it will not be necessary to discuss the prior art anticipation or the question of laches. ’

The original patent to Christensen embraced a braking mechanism for automobiles and similar vehicles to be operated by the conventional foot pedal which applies mechanical braking power and a power brake mechanism using compressed air supplied by an air compressor, tank, power cylinder, and piston.

Claims 2 and 3 of the original patent included a scheme to connect the mechanical with a power brake through the use of what is commonly termed an engineer’s [497]*497valve, so that, when the pedal is depressed in the ordinary way, the mechanical brakes are first applied, and, if the pedal is further depressed, the power braking mechanism is called into action and applies the power brake first to the front wheels of the vehicle.

The original patent was issued in 1919 and the evidence does not disclose that plaintiff, or any one else, ever made a device following the teachings of the patent for practical operation. It was therefore what is commonly called a “paper patent,” and should be strictly, not liberally, construed. Standard Oil Company v. Globe Oil & Refining Company (C.C.A.) 82 F.(2d) 488.

Christensen conceived a plan to connect the foot brake pedal with the power brake mechanism by means of the operation of an engineer’s valve so that when the brake pedal is depressed it applies mechanical braking power and at the same time operates the engineer’s valve to connect the power braking mechanism. Which operates first, the mechanical or the power system, is one of the disputed questions in this case. The specifications and drawings of Christensen indicate that the mechanical brake is applied first, followed by application of the fluid or power brake through the operation of the engineer’s valve.

An engineer’s valve is a mechanical contrivance, usually cylindrical, and having three combinations. It is connected with the atmosphere at one point and with power pressure at another point. There are “off,” “lap” and “on” positions. In the “off” position the atmosphere connection is open, but the pressure connection is closed. In the “lap” position the atmosphere and power connections are closed. In the “on” position the connection to the atmosphere is closed, while the pressure connection is open. The openings, or “ports” as they are called, are for the admission either of air or pressure fluid, and the operator, if pressure is desired, closes the air “port” and opens the pressure “port.” In doing this he must turn the valve so as to pass entirely through the “lap” position. To release the braking mechanism, the reverse of the above movement is required, i. e., the pressure “port” is closed and the air “port” opened, passing back through the “lap” position. To hold any attained and desired brake pressure, the operator reverses the valve far enough to close the pressure port, but not far enough to admit any atmospheric pressure. This is the “lap” position. .

. Plaintiff introduced in evidence a device (Plaintiff’s Exhibit 15) which plaintiff said had installed therein a valve such as is common on streetcars for operating doors by air. This valve was represented as an engineer’s valve that just “happened to be one that we had handy,” one “that had been sent in as a sample.” This exhibit (Plaintiff’s Exhibit 15) was so set up at the trial that pressure must be applied to the pedal by the hand and very slight jiggling of the hand operated foot pedal produceda singular and rather confusing manifestation.

A Ford car was presented for experimentation on the street, and plaintiff represented that it was equipped with a braking device built upon plaintiff’s patent, and contained a valve like the valve in Plaintiff’s Exhibit 15. The car operated quite similarly to Exhibit 15. Then it was discovered that in the valve in Plaintiff’s Exhibit 15, originally a conventional engineer’s valve, the part constituting the “lap” position had been machine tooled away to the extent of about two-thirds of the “lap” or part, rendering it impossible to hold the valve in a definite “lap” position, and accounting for the strange action of Plaintiff’s Exhibit 15.

• Now if, as plaintiff says, the Ford car mechanism contained an engineer’s valve similar to the one in Plaintiff’s Exhibit 15, neither cofild have any probative value. As defendant’s counsel suggest in their brief at page 48, -“the kindest thing that can be said about it is that it is but an experimental device which would commercially prove inoperative,” and if Plaintiff’s Exhibit 15 is commercially inoperative and the braking device on the aforementioned Ford contained within its operating mechanism a valve like the one in Plaintiff’s Exhibit 15, there can be no reliance on the experiments made with the Ford car. It is as commercially inoperative as Plaintiff’s Exhibit 15.

Plaintiff in his reply brief accuses defendant’s counsel of attempting to “becloud the issue” by raising the cry of “wolf.” It is true that the questions to be decided are of the validity of the reissued patent and infringement.

[498]*498■ When it is considered that plaintiff waited sixteen years after obtaining his patent to apply for a reissue, and then made such application for the avowed purpose of bolstering up a lawsuit which he proposed bringing, the court is moved to inquire into the good faith -of the showing and application for the reissue in suit.

It is quite clear that the reissued patent describes, not the original invention of Christensen, but a different device not mentioned-. in the original disclosures.

The original patent, taken together with the drawings and specifications, describes a brake -mechanical combination of power and pressure brake operated by a conventional foot pedal, and when pressure is applied to the pedal the mechanical brakes immediately function, and if pressure is continued on the pedal, the power brake goes into action first on the front wheels. This is not the action of the accused device in which the power brake functions first, followed by application of the mechanical brake system.
