240 F. 749 | S.D. Ill. | 1917
The bill charges infringement of two patents, No. 635,429 and No. 635,430, known as the Culmer patents. The one describes a process; the other, the product derived therefrom. The process consists in violently agitating with air petroleum residuum, while the latter is heated to a relatively low temperature, resulting in an asphaltic product more or less solid and practically without loss; that is 'to say, the volume and specific gravity of the liquid being substantially the same as the volume and specific gravity of the resulting product.
It is admitted by defendant that its process is identical with that of complainant, so that the real controversy here is as to the validity of the Culmer patents. The defenses are: (1) That complainant has not shown a clear title to the Culmer patents. (2) Anticipation by the Byerly patent and prior invention by Byerly.
“It not being the intention of this agreement to interfere with the right of disposition of said patented process on the part of the parties of the first part” (the Culmers).
The two- agreements must be considered together, for the second specifically includes the first, and without the first the second is meaningless. I am of opinion that, notwithstanding the assignment, the legal and equitable title to the patents remained in the Culmers.
The record- of proceedings in Guardian Trust Co., Trustee, v. Cul-mer (no opinion filed), begun in the United States court in Chicago, January, 1901, is significant. The pleadings and the result of the suit convince me that the assignment was a temporary pledge and that it
The further defense is that, regardless of his patent, what Byerly actually did constituted prior invention and use. So far as the proof of such prior invention by the elder Byerly rests in the memory of his two sons, Francis and Josiah Byerly, it is not sufficient to sustain the defense, and the record of certain still books of the father, produced in evidence by the son Francis, is against rather than in favor of the contention that the elder Byerly was the original inventor of the process described in Culmer’s patent. Indeed, the most convincing proof on the subject of prior invention is that contained in the still books, which are now for the first time known in the litigation.
Much time and consideration have been given to the various cases cited by counsel for defendant in which the Byerly or Culmer patents, or both, have been involved. Harmony of decision is highly desirable, and all courts seek to preserve such harmony; but those decrees were all based upon different records, and the decree here must be based upon the record made here.
The equities are found to be with the complainant. Counsel.for complainant may submit form of decree.
