Mid-Continent Inv. Co. v. Mercoid Corp., 43 F. Supp. 692, 52 U.S.P.Q. (BNA) 154, 1942 U.S. Dist. LEXIS 3067 (N.D. Ill. 1942).

Opinion

IGOE, District Judge.

Findings of Fact.

1. Plaintiff Mid-Continent Investment Company is a corporation of Missouri; plaintiff Minneapolis-Honeywell Regulator Company is a corporation of Delaware, licensed to do business in the State of Illinois, with a registered agent in Chicago, Illinois.

2. Defendant, The Mercoid Corporation, is a corporation of Delaware with a regular and established place of business in Chicago, Illinois.

3. Plaintiff Mid-Continent Investment Company brought this suit against the defendant on September 10, 1940, charging contributory infringement of its patent No. 1,758,146, granted Walter M. Cross, May 13, 1930, for a Domestic Heating System, by making and selling combustion responsive low limit controls or switches that may be used in said domestic heating system for the purpose of preventing the fire in the furnace from going out.

4. Plaintiff Mid-Continent Investment Company mailed to the defendant a formal notice of infringement of the patent in suit on November 21, 1932, alleging the accused device in the suit at bar was an infringement of the Cross patents Nos. 1,758,146 and 1,758,147.

5. Plaintiff Mid-Continent Investment Company, during August 1935, brought suit against E. O. Smith of Carthage, Missouri, for infringement of the domestic heating system patent of Cross No. 1,758,146 by installing in his home a heating system including controls manufactured by the defendant.

The Court found the patent valid and that the heating system installed in the residence of Smith infringed the heating system patent of Cross. The Mercoid Corporation provided the defense of Smith but was not made a party to the suit nor was the manufacture and sale of the Mercoid M-61 an issue in this suit.

6. The Cross patent No. 1,758,146 is for a method or system for preventing the fire in an automatic coal stoker furnace from going out during long periods of mild weather by inserting in the automatic control system a low limit switch responsive to combustion conditions within the furnace to operate the stoker whenever a predetermined low temperature within the furnace is reached. It is admitted that Cross did not invent the low limit switch, also called a combustion stoker switch. The combustion stoker switch illustrated in the Cross patent is of the same appearance, construction and operation as the defendant’s Mercoid Figure 37 temperature responsive limit switch patented by defendant and on the market prior to 1925. Defendant placed on the market at the same time the Mercoid Figure 50 temperature responsive limit switch made under the same patent. The Mercoid Figure 50 was modified as to' construction but identical in function and operation and was placed on the market in 1929 as the Mercoid M-51 temperature responsive furnace control. This modification was also patented. The Mercoid M-61 temperature responsive limit switch, the accused device, was made under the same patent as the M-51. and is identical in function, operation and use and in addition is capable of use as a combustion stoker switch when installed in a heating system. The Mercoid TJV and JMV controls, also accused devices, do not operate at a predetermined low temperature.

7. Plaintiff Mid-Continent Investment Company has never made and has never installed heating systems in accordance with the Cross patent No. 1,758,146.

8. Plaintiff Minneapolis-Honeywell Regulator Company upon motion by defendant was made a party plaintiff by order of this Court as the exclusive licensee of the Cross patents Nos. 1,758,146 and 1,-758,147.

9. Plaintiff Minneapolis-Honeywell Regulator Company does not make or install heating systems.

10. Defendant The Mercoid Corporation has never made or installed heating systems.

11. Cross Coal-O-Matic Company, predecessor in title oí plaintiff Mid-Continent Investment Company, did, during the years 1928, 1929, and 1930, engage in the business of installing heating systems including stokers, and controls therefor bought from both defendant and the unwilling [694]*694plaintiff Minneapolis-Honeywell Regulator Company.

There is no proof that Cross Coal-OMatic Company' ever practiced the invention of the Cross patent prior to the grant thereof in 1930.

There is proof that Minneapolis-Honeywell Regulator Company developed its combustion stoker switch independently of the Cross patent and had it on the market prior to the grant thereof.

12. Plaintiff Mid-Continent Investment Company succeeded to the title of the Cross patent No. 1,758,146 on June 2, 1932. Its predecessor in title, Cross Coal-O-Matic Company, on December 23, 1931, granted Minneapolis-Honeywell Regulator Company an exclusive license to make, use and sell and to sublicense others to make, use and sell the inventions described in the Cross patents Nos. 1,758,146 and 1,758,147, as applied to coal stokers, in which it was agreed that the royalty payments to be made thereunder shall be made or based only upon what are known to the parties as a combustion stoker switch, specifically defined as a combustion stoker control unit including an automatic electric switch responsive directly to- temperatures of combustion gases or boiler- water produced by an automatic coal fed stoker. Minneapolis-Honeywell Regulator Company agreed to pay a royalty for each licensed combustion stoker switch made and sold by it and by its sub-licensees.

13. Minneapolis-Honeywell Regulator Company exercised its. right • under its exclusive license and granted a sub-license to Detroit Lubricator Company on July 19, 1933, to make and have made for it and to use and sell combustion stoker switches and to use and sell any and all apparatus in combination with such a combustion stoker switch for use in, or to constitute an embodiment of, the 'invention covered by said patent No. 1,758,146; to pay Minneapolis-Honeywell Regulator Company a royalty for each licensed combustion stoker switch sold by it and to mark each combustion stoker switch made and sold by it under said sub-license with the Patent Notice: “This control carries with it a license to use a system of preventing extinguishment of the fire when operating under low heat requirement conditions as covered by patents Nos. 1,758,-146 or 1,758,147 and/or 1,882,341, as the case may be.” The policy of serving purchasers with notice that its combustion stoker switch carries with it a license to use the system shown in the Cross patents has been continuously followed by Minneapolis-Honeywell Regulator Company to as late as 1940.

14. Plaintiff Mid-Continent Investment Company did not practice the invention but received its revenue from the sale of combustion stoker switches made and sold by its exclusive licensee and sub-licensee both of which conveyed with the sale of each combustion stoker switch a license to use the domestic heating system covered by the Cross patent No. 1,758,146.

Plaintiff Mid-Continent Investment Company has attempted through its method of business to expand the scope of its domestic heating system patent to monopolize the sale of combustion stoker switches not covered by said Cross heating system patent.

15. During February 1932, plaintiff Minneapolis-Honeywell Regulator Company addressed and mailed a letter to a general list of stoker manufacturers entitled “Re: Cross Patents” in which it announced that Minneapolis-Honeywell Regulator Company had obtained an exclusive license under the Cross patents Nos. 1,758,146 and 1,758,147.
