Opinion

CHESNUT, District Judge.

This is a patent infringement suit in equity in usual form. The defences are (1) the¡ invalidity of the plaintiff’s patents and (2) j non-infringement. The defendant also sets up a counter claim based on alleged improper advertising by the plaintiff but it was not pressed.

In view of the extended findings of fact which have been made, this opinion will be limited to the dominant legal questions involved in the ease.

The plaintiff’s patents cover a device made and called by it a “running register” for printer and slotter machines. Its United ¡ States patents Nos. 1,850,800' and 1,850,8021 (hereinafter referred to at times as the “800” patent and the “802” patent) were issued on the samé day, March 22,1932, on applications' therefor filed respectively November 12,1930 and July 30,1981. The first application was required by the Patent Office, by reason of *614 its generic nature, to be divided and tbe second application is a continuation of the initial subject matter. The plaintiff and defendant are, and for many years past have been, the principal competitors in the field of manufacture of printer and slotter machinery. The “running register” is a device whereby the so-called “set-up” time of the machine is materially reduced, and minor adjustments in registry may be made during the operation of the machine, with the result that the per diem production has been greatly increased from what was possible before the adoption and use of the “running register.” Prior thereto necessary adjustments could be made only by stopping the operation of the machine. The need for the running register had long been felt by manufacturers and users of this type of machinery and the plaintiff’s device immediately was adopted by the trade as a very valuable addition to the machines so that all machines of this type now sold by the plaintiff and the majority of those sold by the defendant contain the added device. When the plaintiff’s '“running register” was first brought to’ the 'defendant’s attention it deprecated its utility but very shortly thereafter made a device of a similar nature and obtained a patent (No. 1,868,385) thereon issued to one Greenwood, its employé, under date of July 19, 1932, on application filed August 14, 1931, some six months or more after representatives of the defendant had inspected’one of the plaintiff’s machines with the new device in operation in the plant of a customer of the plaintiff in Baltimore.

The nature of the printer-slotter machines and the functions of the “running register” in connection therewith are aptly described in the brief of plaintiff’s counsel as follows:

“A printer-slotter is a machine whieh prints and slots successively fed sheets of stiff corrugated board to convert said sheets into blanks for making shipping cartons or boxes. ' The machine is used by box makers whose business it is to make boxes of a wide variety of sizes and shapes and with a wide variety of printing to suit the needs of their customers who ship goods in the boxes. The variation in the size; character and printing is necessary because of the wide variety of goods which are shipped in such boxes.

“It is essential that the operating parts of the machine be adjustable so as to .adapt the machine to operate on blanks of different widths and different lengths, and to cut in opposite edg’es of the blanks the necessary slots of different lengths, different spacings and at different distances apart across the sheet. The length of the slots defines the length of the flaps whieh are to be folded over and make the top and bottom of the box, the distance between the slots defines the width of the end flaps whieh correspond to the width of the sides of the box, and the distance between the slots measured across the sheet defines the height of the box.

“It is also necessary to print on the blanks a wide variety of subject matter including the name of the box user, the nature of the contents, the user’s trade-mark, etc. The various printing plates must be capable of being applied in a wide variety of positions so that the printing will be properly proportioned on the sides and ends of the box formed by folding the finished blank.

“In two colors printing on separate successively fed stiff blanks, there are therefore four successive operating mechanisms which act upon the blank and whieh must be brought into registry.

“1. the reciprocating feed mechanism which advances the blank into the machine,

“2. a printing cylinder whieh applies one color to the blank in a predetermined position in respect to the advancing edge of the blank,

“3. a second printing cylinder for the second color whieh applies a second color to the blank in a predetermined position in respect to the .first applied color, and

“4. the slotting heads whieh cut the slots in the front and rear edges of the blank and in predetermined positions in respect to such edges.

“The orders received by the box maker who is using the printer-slotter may be for widely varying amounts. One customer may wish only a few hundred boxes and another may order many thousands at a time. After the completion of each order it is necessary to replace the printing plates by different ones and almost always in some different position on the cylinder, and the knocker feed, the walls of the hopper; the scoring wheels and blades on the slotting heads and the slotting heads themselves must be adjusted to new positions in accordance with the desired characteristics of the next box to be made.

“The machines operate at comparatively high speed and may turn out as many as 200 blanks a minute. Running at this rate an order of 5,000 boxes would be completed in 25 minutes. A record run with one of Plaintiff’s machines using the running register of the patents in suit was 55,000 blanks in 10 hours *615 with 16 changes in the ehaxacter of the blank operated on (See Langston advertisement in 'Fibre Containers’ for December, 1931, Defendant’s Exhibit 15). The only time when the user of the printer-slotter is earning money from the use of his machine is when it is running. All of the soealled 'set-up’ time in malting adjustments between successive runs on different kinds of boxes is waste time and a financial loss to the user of the machine. Therefore the reduction in the shutdown time has from the beginning been a serious problem, and all manufacturers of printer-slotters have been continuously striving to so design their machines that the adjustments may be made in the minimum amount of time, and therefore with the minimum financial loss to the purchaser and user of the machine.”

The plaintiff’s device has successfully solved the problem, by making possible adjustments in the registry of the machine while it is running. The mechanical device, as formally described in Claim 1, of the “800” patent, is as follows:
