Opinions

DYER, Circuit Judge:

Defendant, Florida Machine Products Company, made and sold hair roller holders which admittedly infringed United States Patent No. 3,128,882, entitled “Hair Roller Holder,” invented and owned by plaintiff, Rena Kardulas.1 The District Court found the patent valid and infringed. Defendant appeals [1120]*1120only from the judgment of validity. We reverse because of the exclusion of relevant evidence concerning prior public use.

The Kardulas invention

A beautician needs rollers of many different sizes to set a coiffure. These rollers must be kept clean and easily accessible. Hair rollers tend to become entangled when placed in a pile; to untangle them requires considerable effort and time. This problem is compounded because beauticians usually have only one hand free. They need a means for keeping hair rollers of differing lengths and diameters in a small space within easy reach so that they are readily identifiable, can be picked up with one hand, and can be replaced without disturbing or displacing other rollers.

The invention claimed in the Kardulas patent relates to an improved holder for hair rollers which includes a base with at least two cylindrical carriers spaced apart, each carrier comprising at least three cylindrical surfaces. The junction of cylindrical surfaces with the base of an adjacent cylindrical surface provides at least two shoulder surfaces, each wide enough to support a hair roller. The holder allows one to visually and readily determine the location of a hair roller of a particular size. During use, the holder maintains the rollers in place, each carrier accommodating coaxially mounted rollers of different sizes. While one hand is preoccupied, a beautician can easily locate and identify hair rollers of varying dimensions and can pick up or replace any particular roller with one hand without displacing other rollers.

Since defendant’s infringement is undisputed, the sole issue on appeal is the validity of the Kardulas patent.

Kardulas applied for her patent on July 11, 1963, and it was issued on April 14, 1964. T. R. Snow applied for patent No. 3,221,891 (which completely discloses the Kardulas invention) on June 19, 1963, and it was issued on December 7, 1965. Obviously the Snow application was filed three weeks before the Kardu-las application was filed.

Defendant attacks the District Court’s finding of the validity of the Kardulas patent on three grounds: First, plaintiff failed to introduce sufficient evidence to carry her invention back beyond the date of her application, and the trial court was therefore required to consider that date, July 11, 1963, as the date of her invention. Consequently the prior application of T. R. Snow on June 19, 1963, was equivalent to a publication describing Kardulas’ device before its invention. Second, there was a prior public use of the patented device by Snow. Third, the Kardulas patent is invalid for lack of invention.

The Snow application and Kardulas’ invention date

It is clear that plaintiff invented her device no later than the filing date of her application, since filing constitutes a constructive reduction to practice. James B. Clow & Sons, Inc. v. United States Pipe & Foundry Co., 5 Cir. 1963, 313 F.2d 46, 48 n. 1. But unless Kardulas proved an invention date antedating Snow’s filing date, Snow’s application would constitute a prior publication under 35 U.S.C.A. § 102(e)2 3 fully anticipating plaintiff’s invention. Sperry Rand Corp. v. Knapp-Monarch Co., 3 Cir. 1962, 307 F.2d 344, 346; Van Der Horst Corp. v. Chromium Corp., 2 Cir. 1952, 197 F.2d 791, 794; see Alexander Milburn Co. v. Davis-Bournonville, 1926, 270 U.S. 390, 401-402, 46 S.Ct. 324, 70 L.Ed. 651. Also, it would constitute prior art under 35 U.S.C.A. § 103 3 [1121]*1121Hazeltine Research, Inc. v. Brenner, 1965, 382 U.S. 252, 256, 86 S.Ct. 335, 14 L.Ed.2d 304. Thus, the Kardulas patent would be invalid because Kardulas would not be the first inventor. Alexander Milburn Co. v. Davis-Bournonville, supra at 400-402, 46 S.Ct. 324; Helene Curtis Industries, Inc. v. Sales Affiliates, Inc., 2 Cir. 1956, 233 F.2d 148, 158, cert. denied, 352 U.S. 879, 77 S.Ct. 101, 1 L.Ed.2d 80. Kardulas was shouldered with the burden of carrying her invention date back beyond Snow’s application date. Rooted Hair, Inc. v. Ideal Toy Corp., 2 Cir. 1964, 329 F.2d 761, 767, cert. denied, 379 U.S. 831, 85 S.Ct. 63, 13 L.Ed.2d 40; Syracuse v. H. Daust Manufacturing Co., 8 Cir. 1960, 280 F.2d 377, 379; Pleatmaster, Inc. v. J. L. Golding Manufacturing Co., 7 Cir. 1957, 240 F.2d 894, 898; Oliver Machinery Co. v. Gellman, 6 Cir. 1939, 104 F.2d 11, 13, cert. denied, 308 U.S. 567, 60 S.Ct. 80, 84 L.Ed. 476. See generally 1 A. Deller, Deller’s Walker on Patents §§ 46, 50 (2d ed. 1964) 4

The date of invention cannot be carried back to that of the earliest mental conception. There must be a disclosure sufficient to enable one with ordinary skill in the art to reduce the invention to practice. Casco Products Corp. v. Zaiger, D.Mass.1936, 15 F.Supp. 1014, 1016, aff’d, 1 Cir. 1937, 93 F.2d 210. Kardulas testified that she conceived the invention in September 1960 and commissioned Tanguay, a furniture maker, to construct the parts comprising the carriers for the hair roller holder. Before December 1960, Kardulas had affixed these parts to the tray to form the carriers. Finally, between December 1 and December 15, 1960, she showed a model to her attorney, Nedvad, who corroborated her testimony.5 The model was properly identified and received in evidence without objection as the model shown to Nedvad.

While it is well settled that the uncorroborated and undocumented testimony of the patentee is insufficient to prove invention date, Rooted Hair, Inc. v. Ideal Toy Corp., supra, 329 F.2d at 767; Pleatmaster, Inc. v. J. L. Golding Manufacturing Co., supra, 240 F.2d at 898; Thomson Industries, Inc. v. Nippon Thompson Co., E.D.N.Y.1968, 298 F.Supp. 466, 472, we find that the testimony of Kardulas was in this instance sufficiently corroborated to prove invention date, and the model coupled with Nedvad’s identification satisfied the documentation requirement. Furthermore, the model, crude as it may be, clearly provided a sufficient disclosure of the invention to enable one with ordinary skill in the art to reduce it to practice. In fact, the invention embodied in Kardulas’ model was fully reduced to practice in December 1960. The only refinement remaining was to perfect the hair roller holder into a commercially marketable form, and this Kardulas was not required to do. Hildreth v. Mastoras, 1921, 257 U.S. 27, 34, 42 S.Ct. 20, 66 L.Ed. 112; Radio Corp. of America v.
