Automotive Maintenance Mach. Co. v. Precision Instrument Mfg. Co.

June 26, 1944

AUTOMOTIVE MAINTENANCE MACH. CO.
v.
PRECISION INSTRUMENT MFG. CO. ET AL.



Appeal from the District Court of the United States for the Northern District of Illinois, Eastern Division; Michael L. Igoe, Judge.

Author: Sparks

Before SPARKS and MAJOR, Circuit Judges, and LINDLEY, District Judge.

SPARKS, Circuit Judge.

On June 15, 1942, plaintiff charged Precision Manufacturing Company, Kenneth Larson, and Walter Carlsen with infringement of United States patents to Larson, No. 2,279,792, and to Zimmerman, No. 2,283,888. By amended petition filed November 30, 1942, it further charged infringement of reissue patent No. 22,219 of which patent No. 2,269,503 was the original. These patents wre issued, respectively, on April 14, May 19, and November 3, 1942, on applications filed respectively jon October 1, 1938, November 22, 1937, and May 31, 1938. All of them relate to torque wrenches, and the applications were assigned to plaintiff.

The joint amended answer of the defendants, filed February 8, 1943, alleged that the defendant Larson had committed perjury by filing a false affidavit with the Commissioner in support of his patent, in an interference proceeding between that patent and the Zimmerman patent No. 2,283,888; that plaintiff knew of that perjury prior to December 23, 1940, and failed to divulge it to the proper authorities; that by reason of that knowledge it threatened the defendants with criminal prosecution unless the defendants would sign the contracts hereinafter referred to, and it promised defendants that it would suppress such evidence of perjury as it had, if defendants would sign the contracts; that under and by reason of those circumstances they signed the contracts against their will; that those contracts were unreasonable and unconscionable and their execution by defendants was procured by the inequitable conduct of plaintiff by which its hands were soiled to such an extent that its bill of complaint should be dismissed.

July 6, 1942, Snap-On Tools Corporation filed a petition for a declaratory decree relating to the controversy with respect to the Larson patent and the contract of December 20, 1940, which plaintiff and the defendants, Larson and Precision, had signed. In final form, by amended petition filed March 1, 1943, the facts therein alleged are substantially the same as set forth in the answers in the other suit. Automotive by way of answer and counterclaim set forth substantially the same allegations, and demanded practically the same relief as demanded in its original action.

By agreement, the two cases were consolidated for hearing on the sole question of inequitable conduct, and voluminous evidence was heard. At the close of the arguments, the District Court rendred an oral opinion on May 21, 1943, which is not in this record, and on July 12, 1943, it filed its special findings of facts, and rendered its conclusions of law thereon. At the same time it filed the following:

"Memorandum.

"In this case, the court rendered an oral opinion at the closing of the arguments. At the request of M. K. Hobbs, an attorney who testified in the case, the court has re-examined the record.

"It is not the intention of the court that the statements in the opinion should be construed as implying that Mr. Hobbs had willfully given false testimony or had been guilty of professional misconduct. Accordingly, the oral opinion is withdrawn and is not to be filed as a part of the record. The Court has entered written findings and conclusions. It appears from an examination of the record that the witness Hobbs did not testify falsely; that he has adhered to the rules which govern the relations existing between attorney and client and that he was not guilty of any professional misconduct or criminal act."

Upon the conclusions of law, and consistent therewith, the court rendered judgment dismissing the complaint, the amended and supplemental complaint of the first action, and the petition, amended petitions and the counterclaims of the second action, all for want of equity. It further ordered that there should be no award for costs. From that judgment Automotive has appealed. Plaintiff and the corporate defendants, including Snap-On, which is considered as a defendant herein, will be hereafter referred to respectively by the first word of their corporate names.

Prior to 1938, Automotive was engaged in the production of a torque wrench invented by Zimmerman, one of its employees, and Snap-On was one of its customers for that wrench.

In 1938, George Thomasma, one of Automotive's trusted employees, who was fully acquainted with its wrench business and with the Zimmerman developments, secretly gave information to the defendant Larson, and they, with one Carlsen, Cooperated to establish a competing business with Automotive. Snap-On was approached by Larson with respect to its taking on the wrench which had been developed by him and Thomasma from the Automotive wrench.

On October 1, 1938, Larson filed his application for his patent above referred to, by Alberts, who was then attorney for both Larson and Snap-On. The application was assigned to Snap-On under the terms of an agreement between them dated September 28, 1938.

At that time the application did not claim anything that was common to the Zimmerman and Larson wrenches, but the claims, as interpreted by the disclosure, were limited to a detail which comprised a tail-piece for operating a gauge mechanism. This, we think the evidence clearly discloses, was Larson's contribution, and it was so asserted at the trial by Alberts.

On October 18, 1938, Alberts, Snap-On's patent attorney, had Larson execute for Snap-On an affidavit to the effect that no employee or ex-employee of any competitor of Snap-On had anything to do with the development of his wrench, or would be associated with Larson in the enterprise; that he alone had invented ...
