The opinion of the court was delivered by: LUHRING
This is a proceeding under 35 U.S.C. § 63, 35 U.S.C.A. § 63, to obtain a patent. The cases were consolidated for trial.
In Equity No. 66,339, the patent sought is for an "Apparatus and Process for the Production of Carbon Black and Acetylene by the Pyrolysis of Hydrocarbon Gases and Vapors."
The application was filed with the Patent Office on July 16, 1934 and was given serial number 735,442. There were twenty-four claims, all of which were rejected by the Examiner on the prior art. On appeal the Board of Appeals affirmed the decision of the Examiner July 31, 1937. The bill of complaint herein was filed January 21, 1938.
At the pretrial hearing, October 11, 1939, the plaintiff, having withdrawn sixteen of the claims, left for consideration of the court claims 13, 27, 28, 33, 34, 38, 39 and 49.
Equity No. 66,340 involves plaintiff's application number 733,794, filed July 5, 1934 for a patent on a "Process of Obtaining Carbon Black by the Prolytic Dissociation of Hydrocarbon Gases and Vapors."
Thirty claims were involved in this application and were rejected by the Examiner and held to be unpatentable over the prior art. The Board of Appeals affirmed the decision of the Examiner July 31, 1937. The complaint was filed in this court January 21, 1938.
The plaintiff at the pretrial hearing withdrew nineteen of the claims, thus leaving for consideration by the court claims numbered 3, 4, 11, 18, 20, 23, 29, 31, 32, 33 and 38.
On the hearing of these cases, the court was furnished with copies of the patents exemplifying the prior art cited by the Examiner, the Examiner's statement on appeal and the opinion of the Board of Appeals.
The plaintiff placed in evidence a copy of the specifications and drawings, an analysis of the claims and a so-called "Digest of Patents cited in Prosecution of Serial No. 735,442" and of serial number 733,794, having reference to the prior art involved in Equity No. 66,339 and 66,340 respectively. The plaintiff gave oral testimony.
The plaintiff in his brief states: "The sole controversy in the instant case is whether or not prior issued patents anticipate the inventions of plaintiff, and whether or not plaintiff has satisfactorily differentiated its invention from this prior art by the terminology and limiting elements included in the claim in suit."
The only purpose of the proceeding here is to secure a review of the patent office record. It is an appeal from the decision of the Board of Appeals of the Patent Office. The testimony of the plaintiff is cumulative. The Patent Office tribunals have applied the references in detail to the claims in issue and have clearly pointed out wherein such claims are unpatentable over the prior art.
"In the mine-run of cases that come up through the Patent Office the record of the trial court is a mere repetition of the record of the Patent Office. In such situations, i.e., where the new evidence is not important or at most cumulative in nature, it is only reasonable that the finding of the Patent Office should assume 'well nigh dominating importance' in the ...
