Opinion

BARNES, Circuit Judge.

This is a suit for infringement of United States Letters Patent No. 2,138,-172, for a concrete Batching Apparatus invented by plaintiff’s assignors. The patent issued November 29, 1938, expired November 29, 1955. (The filing date was February 10, 1937.) Suit was instituted August 25, 1954. By the time trial was had, the prayer for injunctive relief was moot.

The invention may be succinctly described as a combination patent, whereby a cement hopper is centrally located within an aggregate (sand and rock) hopper, each hopper being independently supported so that their contents can be separately weighed, with the respective hopper discharge gates being so concentrically located that the cement is discharged simultaneously (or nearly so) with the aggregate, by gravity, through the center of the “flowing shaft of aggregate,” while water is supplied to the aggregate by a tubular stream sur *794 rounding the aggregate. The simultaneous fall causes a certain amount of “commingling,” prior to the batch reaching the pre-mix truck or mixer. If no water is added, a dry batch is, to a certain extent, “commingled.”

By such a procedure, various advantages are claimed: (1) a reduction in the amount of cement lost through “dusting; ” (2) the reduction of “balling” and “gumming” by preventing the cement from hitting the mixer sides or mixer blades before the aggregate does; (3) a speeding up of the final and necessary “pre-mixing,” or “mixing;” (4) a preshrinking of the size of the total of ingredients prior to’ transportation to the job site; and (5) some reduction of batching plant size and height, with resultant cost of construction saving.

By stipulation [Tr. 29, 151], the trial proceeded only as to claims 1 and 5 of the patent. As appellant says:

“Claim 1, 1 shown in plaintiff’s Exhibit 15, is a broad claim which covers * * * all the accused plants. * * * ” “Claim 5, 2 shown in plaintiff’s Exhibit 17, is a much more specific claim which covers * * * ” but two plants.

“From the above it will be understood that Claim 1 must be held valid and infringed if plaintiff is to be given substantial relief. The upholding of Claim 5, although also much desired by plaintiff, will result in greatly diminished relief since Claim 5 covers two plants only.”

Claims 1 and 5 were held invalid by the trial court, solely on the ground of an alleged prior public use at a batching plant constructed and operated by strangers to the present action at 235 Alabama Street, San Francisco, California. [Findings of Fact and Conclusions of Law, Tr. pp. 78-84]

It is obvious from a reading of the Transcript that the defendant discovered at the last minute the prior use relied upon at the trial. Counsel for defendant at the conclusion of the direct testimony of plaintiff’s first witness, on March 13, 1956, (a Tuesday) advised the court and opposing counsel that on the preceding day, Monday, he had received for the first time drawings of an alleged prior use; and that his client, the defendant, had heard about such prior use “the middle of last week,” [Tr. 157] and defense counsel learned of it “last Thursday or Friday, Friday afternoon.” (March 9th, 1956.) [Tr. 160]

While the defendant’s answer had raised a claimed lack of invention in plaintiff's patent, and a sale in this country “more than two years prior to the date of the application for the patent in suit,” the pretrial memoranda filed by counsel for defendant on March 7, 1956, did not mention the specific prior use introduced and primarily relied upon, at the trial.

It should be noted here that the plaintiff had filed its pretrial memorandum on July 20, 1955. It had urged and insisted on trial as soon as possible. Defendant, (whether through fault or otherwise) had caused and apparently welcomed de *795 lay, and had substituted new defense counsel at a late date, after the first counsel for the defendant had requested that he be substituted out. New defense counsel filed a motion to continue the trial which was denied. Due to congested court calendars, there was delay before trial of the action could be reached.

Plaintiff urges this Court to reverse the lower court’s findings and judgment because-

Point I. The trial court erred in finding the evidence on the apparatus at 235 Alabama Street, San Francisco, California, to be such as a matter of law, as to invalidate claims 1 and 5 of Johnson patent No. ’ ’ '
“Point II. The trial court abused its discretion by admitting evidence relative to the Alabama Street plant despite failure by defendant to comply with 35 U.S.C. 282.
„„ • . T7r rm j j. • “Point III. The documentary evi- , , ,. , .. , ox x dence relative to the Alabama Street , , . , , , plant is hearsay, and was not prop- , , TT _ erly admitted under 28 U.S.C.1732 (a).’; [Appellant s Open. Brief, pp. ii, iii],

, and further urges Point IV, that the defendant’s infringement is clear, and therefore, Point V, there is no necessity of a remand.

Because we cannot agree with appellant’s first three points, and hence affirm the lower court, we need not deal with Points IV and V. We will discuss the first three points in turn.

“Point I. The trial court erred in finding the evidence on the apparatus at 235 Alabama Street, San Francisco, California, to be such, as a matter of law, as to invalidate claims 1 and 5 of Johnson patent No. 2,138,172.”

Here the trial court, (if we assume the evidence of prior use was properly before it) had the testimony of three witnesses to rely on: Murasko, Cornett, and Bodinson, together with many written Exhibits. Certainly the individuals gave testimony, which, if believed by the trier 0f fact, was sufficient to justify the finding of prior use here questioned. 3

A carefui review of the entire record leaves no doubt in our mindg but that a certain batchi plant existed on Alabama Street in San Francisco as early as 1931, and perhaps 1930. There were many details given by the witnesses above named, (such as jobs supplied with concrete mix from this plant, giving names and locations, and the years supplied). It is true that the existence of „ ' i x» • moi ,, a batching plant m 1931 or 1932 does , ,, . . „ , , . ., not prove the existence of a plant similar , , . . ... ,. to plaintiff s claimed invention, nor one wbich demongtrated a prior use of the patented art. But this preliminary deficiency was amply made up through the detai]ed and knowledgable testimony of Muragko. He testified he was present when the batching machinery was installed and helped install it. He operated it from 1931 until the last day of May, 1942. He had been in charge of a somewhat similarly constructed batching plant at another (Geneva Avenue) address, and came to the Alabama Street
