Opinion

DUNCAN, District Judge.

On November 30, 1949 the court found that Edward W. Town was “the true, first and original inventor and discoverer of the invention described in Letters Patent No. 2,392,513;” that said Letters Patent were issued on January 8, 1946 and in all respects was a valid patent; said Letters Patent described an invention in cushions for artificial dentures; that the Ezo Prod[438]*438ucts Company at the time of the filing of the suit resulting in the decree holding the patent valid, was the exclusive licensee of said Letters Patent.

The court further found that the device manufactured by the' Ezo Products Company was infringed by a device made by the defendant George H. Willis, doing business under the firm name and style of “Sealtite Dental Pad Company” and the “defendant and his employees, agents, associates, confederates and representatives, and each of them, is and are hereby perpetually enjoined and restrained from manufacturing, selling, distributing, or causing to be made, sold or distributed, or otherwise handling or disposing, directly or indirectly, .Cushions for Artificial Dentures made in acordance with Claim One of the patent in suit.”

An order was entered staying the execution of the judgment pending appeal, provided that within fifteen days following the entry of the decree, the defendant file an undertaking under seal, to be approved by the court, in the maximum penalty of $15,000.00 conditioned for the satisfaction of said judgment in full, together with any profits and damages which may have been ¡sustained by the plaintiffs and adjudged against the defendant between the time of the filing of the decree and any order affirming it. The defendant did not execute the supersedeas bond as provided in the order of the court.

On February 28, 1950 the plaintiffs filed a petition asking that the defendant be required to show cause why he should not be adjudged by the court to be in contempt for violating its decree in this cause, and be punished for the same.

The petition alleges that in violation of the court’s order the defendant “has continued to practice the teachings of the patent in suit and is still continuing his acts of infringement.”

The show cause order was issued on February 28, 1950 and the defendant filed his response thereto, alleging that he was unable to file the undertaking, i. e., the supersedeas bond, as provided in the decree of the court. The defendant alleges: “That the evidence which Petitioner identifies in paragraph ten (10) of its Petition for Order to Show Cause relates to ‘dental base plates’ produced subsequent to the aforesaid Decree and in accordance with the teaching of expired U. S. Letters Patent No. 606,198, issued to W. R. Evans on June 28, 1898, and pertaining to ‘Dental Base Plates.’ ”

The respondent denies that he has intentionally or otherwise violated the injunction of the court. The matter came on for hearing, and the plaintiff, to sustain its petition, called the defendant as a witness, and he described the method of manufacture of the device he is now making, which is alleged by the plaintiff to be in violation of the court’s injunction.

The issue is simple, and I think purely one of law. There is no dispute as to the facts. The sole and only question is whether or not the device now being made by the defendant out of what he described as a “soft absorbent material” infringes plaintiff’s patent and manufactured device made of cotton flannel with nap on each side. Claim No. 1 of plaintiff’s patent which the court ruled the defendant’s original device infringed, provides: “A cushion for an artifical denture comprising a piece of sheet material cut to the form of the denture and inserted between the denture and the gum, said material being impregnated with a nonsoluble wax composition which is plastic but which does not melt at body temperature.”

The method of manufacturing the accused device is fully described in the court’s Memorandum Opinion filed herein on August 3, 1949, D.C., 85 F.Supp. 483. The device manufactured subsequent to the injunction, is identical in appearance, except under the closest scrutiny. Unless one’s attention had been called to the fact that the accused device and the subsequently manufactured device were made of different kinds of cloth, one not concerned with distinguishing the difference could not be expected to do so.

The original accused device, as was the patented device, was made of cotton flannel with a nappy surface on each side, as de[439]*439scribed in the specifications of the plaintiff’s patent and in the Memorandum Opinion of the court.

Respondent has now substituted for that cloth, what he describes as a “soft absorbent material” and instead of dipping such material, after it is colored in indentically the same manner as the cotton flannel, a layer of paraffin and beeswax is caused to be formed in a shallow rectangular pan and the material is cut into strips, just as it was before, except narrower, and placed over the strip of paraffin and beeswax. A hot roller is then caused to be rolled over the cloth, thus causing it to be impregnated with the solution of heated paraffin and beeswax. The cloth composing the original accused device was impregnated with 100% paraffin, whereas the defendant says his present solution is composed of 99%% paraffin and %% beeswax.

Thereafter the impregnated cloth is again cut into strips three inches wide and run through the same press and cut into identically the same shape and design as the accused device. Thereafter, the devices are packed 20 each in a box and sold in gross lots — 12 packaged boxes to a container.

The defendant contends that the cloth from which the device is produced is impregnated on one side only, but an inspection both of the cloth from which the device is made and the device itself, clearly reveals that there is a substantial coating of paraffin on both sides, although unquestionably when the cloth is first impregnated, there is a greater amount on one side than on the other. After a comparatively short time, it is difficult from observation to determine the distinction between the amount on either side of the device.

The device thus created is identical in appearance, performs identically the same function in identically the same manner as the accused device. The only distinction is that one is made of a flannel cloth with nap on each side, and the other is made of a “soft absorbent material” and there is slightly more paraffin on the accused device than there is on the subsequently manufactured device, just as there was more .paraffin on the accused device than there was on the patented device, as discussed in the Memorandum Opinion.

The respondent contends that he is manufacturing the device in accordance with the teachings of Evans No. 606,198 patented June 28, 1898. It seems to me that it is scarcely necessary to describe the difference between the device now being made by the defendant and the device described in the Evans Patent. The Evans patent claims:

“1. A new product for making base or trial plates, for use by dentists, consisting of a sheet of wax and a sheet of cloth, the two being united to form a composite sheet of wax and cloth, the cloth being on the side of the sheet which is to come in contact with a plaster model, and subsequently with the gums in a human mouth, substantially as and for the purpose set forth.
“2. A dental base or trial plate
