Opinion

MEANEY, District Judge.

Findings of Fact

1. Plaintiff, U. S. Chemical Corporation, a corporation incorporated under the laws of the State of New Jersey, is assignee of U. S. Letters Patent No. 2,-668,328, application for which was filed April 8, 1953, issued to Frank E. Porter on February 9, 1954. Plaintiff, U. S. Plastic Products Corporation, also a New Jersey corporation, is exclusive licensee.

[841]*8412. Defendant, Plastic Glass Corporation, is a corporation incorporated under the laws of the State of New Jersey.

3. Plaintiffs bring this action alleging infringement by defendant of claims 1, 3 and 4 of the patent, 35 U.S.C.A. §§ 271 and 281; 28 U.S.C.A. § 1338(a). Defendant denies infringement, counterclaims for declaratory judgment of invalidity under the Federal Declaratory Judgments Act, 28 U.S.C.A. § 2201, and counterclaims for an injunction and accounting on the basis of alleged unfair competition. 28 U.S.C.A. § 1338(b).

4. The patent in suit is for the process of “Casting Patterned Plastic Sheets.” The avowed object is to effect a “controlled orientation of pattern forming additives of cast synthetic resin sheet.” This, in more comprehensible terms, is plastic sheeting containing a simulated mother-of-pearl design. The basic material used in this process is a syrup known as monomeric methyl methacrylate. Added to this is a polymerizing catalyst, and a pattern forming material, usually guanine crystals prepared from fish scales, which gives the final product its iridescent appearance. This combination is heated until the desired viscosity is obtained. Then discrete particles — i. e., particles that can act strictly on their own, each as an individual particle — of a selected mesh size and a desired quantity are added to the molding composition. These are described in claim 1 as being “discrete particles of solid material of such weight and bulk as to sink by gravity”; in claim 2 as “discrete solid substantially spherical particles of a composition to blend with liquid and of such weight and bulk as to sink by gravity”; and in claim 3 as “a plurality of transparent beads of a composition and to be at least partially melted at the temperature of the liquid material and of such weight and bulk as to sink by gravity.” The principal type used and in contention is transparent beads of acrylic resin — polymerized methyl methacrylate balls, having a low molecular weight and melting point and being compatible with the molding composition, in form of a solid material. The mixture formed is agitated and then poured into sheet molds which are spaced to remove the excess air and adjusted to the desired thickness. The mold is then turned on its end —vertically—and placed in a controlled temperature bath. The solid particles, being of greater density than the syrup, sink to the bottom by gravity. The bath acts to polymerize the entire composition and is so controlled that the solid fragments will sink a substantial distance before the complete polymerization occurs. As the bead sinks it carries with it a glob of viscous resin containing the pattern-forming material. This action forms a distinctive pattern because of the orientation of the guanine crystals in the mass. The product of the complete polymerization process is a plastic sheet containing a pearl design. This process permits the production of various designs reproducible to the extent that there is sufficient similarity between sheets to allow economical manufacture of the end product desired.

5. The counterclaim asserts the usual grounds for invalidity, but because of the determination hereafter to be made it is necessary only to decide the issue of public use and sale of the patented process more than one year prior to April 8, 1953.

6. Frank E. Porter, the patentee of the process, is a chemical engineer and has spent all of his career working in the plastics field. He has been working with methacrylate resins since 1936, spending a large part of his time experimenting with pearl design sheeting. He had several false starts and one particularly bad setback some time during the period 1947 -1949 when he used wax as the design-producing medium and obtained a very nicely designed material. However, after sale and manufacture into handbags it was discovered that the plastic “blushed containing absolutely white streaks” from absorption of moisture from the air.

7. Porter entered the employ of U. S. Plastic Products Corporation in Febru[842]*842ary, 1951, primarily to set up operations for the easting of clear and smooth pearl methyl methacrylate sheeting. U. S. Plastic Products Corporation at that time was producing a methyl methacrylate molding powder in the form of spheroidal beads with a low molecular weight and melting point for use in dental plates— the very same material he has incorporated into his patent as the pattern-forming substance.

8. After a period of laboratory experiment, and on September 27, 1951, Porter produced a full size sheet of design pearl sheeting using substantially the same process described in the patent in suit. This sheet was delivered to Handbag Metal Specialties, Inc., a New York corporation, which made a test handbag for use in aging and control tests. What these tests consisted of is not apparent, but they seem to have been merely to let the handbag sit in one place to determine whether the design would fade out. There is some vague testimony that other sheets were similarly used and that is accepted as a fact.

9. Beginning in November, 1951, and thereafter, sales were made to Handbag Specialties — 24 sheets in November, 20 sheets in December, and in January, 1952, 89 sheets were sold to the same company. In February, 1952, sale of the sheets was also made to two other manufacturers, Jewel Plastics Company and Rialto Button and Wood Products, the total number of sheets being 203. In March, 1952, sales were made to the same three customers of 240 sheets. In April, up until and including April 7, 89 sheets were sold. The price was computed not on the basis of a sheet as a unit, but on the basis of a pound as a unit, the price in all instances during this period except two being $2 per pound. The aggregate invoice amount was $15,734.25.

10. All of the evidence of experimental use comes from the oral testimony of the patentee, Frank E. Porter, and Samuel Brass, president and sole stockholder of U. S. Chemical Corporation and president of U. S. Plastic Products Corporation (the latter’s testimony contained in a deposition presented in evidence without objection). Porter testified as to a number of so-called “tests” carried out during the critical period. The first test mentioned has been referred to in finding of fact number 8. The second was not a test of the process at all; it was simply a realization that a thicker sheet was necessary for the manufacture of ladies’ handbags. The other tests referred to — -on January 25, 1952, March 28, 1952, May 12,. 1952 and June 5, 1952— ostensibly were to determine whether a controllable process had been discovered so that it was now possible to produce the same design in varying thicknesses of plastic sheets. This view, that the primary motive was experimental, cannot be accepted. At page 64 of the transcript Porter was asked by the plaintiff:

“Q. Now, Mr. Porter, these experimental runs that you are referring to in your notebook, were they experimental runs for the purpose of working out production controls ?”

To which he answered:

“A. These things were all done because they were requested by the customer.
