Opinion

SCHNACKENBERG, Circuit Judge.

Plaintiff brought an action for patent infringement in the district court against Avco Manufacturing Corporation 1 and its Chicago area distributor, The Harry Alter Co., Inc. The patent in suit was directed to a synchronization system for television, and is known as Toulon reissue patent, No. 22,055. Avco counterclaimed asking a declaratory judgment of invalidity, noninfringement and un-enforceability of said patent, and for damages.

The district court entered a consent order of noninfringement as to claims 1 to 4 inclusive, which were included in the original patent and repeated without change in the reissue, and as to claims 8, 11 and 12, added by reissue. The district court, 126 F.Supp. 595, made findings of fact and conclusions of law, held reissue claims 5, 6, 7, 9, 10 and 13 to be valid and infringed, entered a judgment which enjoined further infringement, awarded damages and costs to plaintiff and dismissed Avco’s counterclaims. From that judgment Avco took this appeal.

The original Toulon patent 2 was issued on an application filed July 3, 1937. This invention comprises a basically new type of synchronizing system for electronic television receivers. It relates to a type of synchronization, generally known as “automatic frequency control." Such control is a corrective method used *139 in conjunction with a controlling source, for maintaining the proper speed or frequency of operation of a controlled device.

In 1938, Toulon submitted his application to plaintiff and others for purchase. They rejected it. Thereafter, on February 5, 1940, one of plaintiff’s engineers, Loughren, devised an automatic frequency control system. In July 1940 plaintiff reopened negotiations with Toulon’s United States agents, for the purpose of purchasing the Toulon application, which at that time had been allowed 3 with four claims, but the patent had not been issued because of failure to pay the final statutory fee. On September 12, 1940, plaintiff purchased the Toulon application from his agent Langley, under an agreement that plaintiff had the right, at its own expense, to further prosecute said application. Langley knew that plaintiff intended to seek a reissue of the patent which was then expected to result from Toulon’s application. An assignment of the original patent to plaintiff, an application for a reissue thereof and a reissue oath were sent to Toulon through Polydoroff, his agent. They were signed by Toulon and returned to plaintiff’s attorneys. The final fee was paid and ac-. cepted by the patent office.

The reissue application was filed April 23, 1941 and the reissue patent (Re. 22,-055) which is involved in this action, was issued thereon on March 24, 1942. The reissue patent claims, according to plaintiff, are simply more accurate and more complete definitions of Toulon’s invention; they are in some respects broader and in some respects narrower than the original claims. Defendants contend that the reissue claims are not for the same invention as the original patent.

The contested issues, stated affirmatively by defendants, are: The claims in issue are invalid, the reissue patent is unenforceable, the claims in issue are not infringed, and plaintiff has violated the anti-trust laws by block-booking its patent.

1. The first reason advanced by Avco to sustain its contention that the reissue claims in issue are invalid, is that they were granted through “factual technical error.” This court’s attention is directed to proceedings said to have occurred in the patent office which resulted in the allowance of claims 5 to 12 inclusive, after they had been rejected by an examiner, and the adding of claim 13. The amendment to each of claims 5 to 12 inclusive was made by inserting the phrase:

“in the absence of a frequency-correcting control voltage applied thereto.”

Avco cites certain evidence in the record which it says shows that this amendment made the claims factually incorrect.

We agree with plaintiff that this contention is not properly before us for determination. Avco’s answer and counterclaim make no specific reference thereto, nor is there anything in the record to indicate that this issue was presented to the district court. While Avco in its reply brief states that the issue was covered in its proposed findings of fact and conclusions of law, no submitted finding or conclusion specifying that issue has been included in the record before us. Avco in its brief states that the district judge made no specific findings on this issue. We are not surprised at that statement in view of the total failure of the record before us to show that that issue was ever raised in that court. Therefore, we cannot consider it here.

2. A principal question in this case is whether the reissue patent is for the same invention as that covered by the original patent. Avco contends that the reissue patent is invalid because, inter alia, it is not for the same invention.

The evidence indicates that what is known as synchronization is a troublesome feature of a satisfactory television system. By synchronization is meant the method to keep the scanning of the image *140 at the transmitter and the scanning of-the picture tube at the receiver in step or in gear. This synchronization is effected by sending out a very short electrical synchronizing pulse (sync pulse) 4 at the end of each series of lines, called a field. At the receiver, these synchronizing pulses are separated from the image signals and utilized to control generators of scanning waves which cause the cathode-ray beam to scan the face of the picture tube. If the scanning at the receiver loses synchronization, that is, gets out of gear with the transmitter, the lines of the reproduced image may begin at various points across the tube face and the image becomes distorted.

The background against which Toulon conceived .his original patent 5 , issued by the United States Patent Office on January 7, 1941, on his application filed on July 3, 1937, is revealed by the evidence in this record. The earliest work on television systems, in the 1920’s, was directed to complex mechanical devices which, while operative, were never developed to a commercially practical form. The synchronization of such systems was quite different in character because of the high inertia of the mechanical moving parts, which also made them inherently relatively immune to noise interference. The next stage in the development of the art was that including the all-electronic receiver which reached commercial form in England in 1937 and in the United States in 1940. Such receivers were of the “triggered” type, that is’, of the type in which a horizontal syne pulse at the end of each line triggered the receiver scanning oscillator to initiate the succeeding scanning line and in which the vertical synchronizing system was of a Similar type.
