Opinion

STEPHENS, Circuit Judge.

Solex Laboratories, Inc.,- as the as-signee of- Kevin M. Tuohy, was issued Patent No. 2,510,438 on June 6, 1950. The patent claims a contact vision corrective lens which fits on the cornea 1 of the eye.

Contact lenses are admittedly old in the art of vision correction. However, the contact lenses in general use prior to the Tuohy patent were shaped to the identical curvature of the fitted eye and were held in.place by the use of scleral flanges that extended over the white of the eye and under the eyelids. 2 Their design cut off the flow of natural fluids, blood and oxygen to the eye. Therefore, the use of contact lenses required the insertion of a buffer solution between the eye and the lens. The buffer solution had to be specially prepared for each person and, even with its use, the lenses could be worn for an average of only four hours.

Tuohy’s claim of invention lay in the development of a contact lens which eliminated the need for buffer solutions and which coüld be worn for long periods without causing eye irritation. Tuohy accomplished this result by eliminating the scleral flanges and making a lens slightly smaller than the limbus 3 *531 portion of the eye, but larger than the maximum opening of the iris and by making the radius of curvature on the concave side of the lens slightly greater than the radius of curvature of the eye at the cornea 4 upon which the lens rests, thus enabling the natural fluids to reach all portions of the eye. The lens has less curvature than that of the eye and rests on the cornea only at its center point. Yet the lens remains in place, probably through capillary action, and by the slight protrusion of the limbus; and any tendency on the part of the lens to slip off the apex of the cornea can be countered by blinking the eyelids. The inside marginal edge of the lens is beveled both for smoothing and to enable the lens to pass over the raised limbus.

Solex markets its lens under the name “Corneal” or “Tuohy Corneal”. In June, 1950, after receiving its patent, Solex notified Dr. Morris Green (party defendant) that the contact lens which he was selling infringed Solex’s newly acquired patent. Dr. Green nevertheless continued his activities and on October 25, 1950, Solex filed suit praying that Dr. Green, and Pacific Contact Laboratories, Inc., which is under his control, and Lee W. Hoggan, who is the manager of Pacific Contact Laboratories, Inc., be enjoined from infringing Solex’s patent and from using the “deceptively similar name ‘Cornea’ ”. Solex further sought an accounting for profits and damages, plus costs and a reasonable attorney’s fee.

The district court found the patent valid and infringed, and that defendants’ use of the words “Cornea” and “Corneal” amounted to unfair competition with Solex’s use of the words “Corneal Lens” and “Tuohy Corneal Lens”. The defendants were enjoined on both counts and Solex was awarded damages in the amount of $5.00 per pair of contact lenses sold 5 by defendants, plus costs, and $500.00 as attorney’s fees. Defendants appealed.

Appellants challenge the validity of Patent No. 2,510,438 on four separate grounds, namely: (1) Tuohy did not invent the corneal type contact lens; (2) The Corneal type contact lens claimed by Tuohy lacks any “flash of creative genius” ; 6 (3) The claims do not describe the alleged invention in a clear and definite manner; 7 (4) The Tuohy patent is at best a “method” patent and as such cannot be protected by an “article” patent. 8

The district court concluded that the patent was valid as to each of the two claims made, 9 and we may not disturb the court’s conclusion since it is *532 supported by findings of fact which we do not regard as clearly erroneous 10 for the reasons hereinafter stated.

Did Tuohy Invent the Corneal Type Lens

Appellants contend that the corneal contact lens was anticipated by an invention of E. Kalt as disclosed ,in 1942 in the book “Contact Lenses” by Obrig, 11 which was admitted, into evidence. Kalt’s development was described

in the Obrig book as follows:

“He [Kalt] ground some small lenses to correct keratoconus 12 which had no scleral band, and rested at the edge of the cornea. They were designed to exert some pressure on the apex of the conus in an attempt to reduce the ecstasia as well as to correct the visual error. "'As might be expected, they were unsuccessful.” ' .

The Patent Office issued Patpnt bTo. 2,-510,438 with knowledge of the Kalt' lens and the Obrig book. The district court considered the Kalt lens and rejected it as an anticipation. The quotation itself shoes' both that the objective which Kalt sought to reach was different from Tuohy’s objective and that the Kalt lens was unsuccessful. If a prior art device is adaptable to a purpose, but it is not so adapted, ;that is evidence that the changes required more than mere mechanical’ skill and may support a conclusion of nó anticipation. 13 And a prior unsuccessful experiment does , not constitute invention and cannot therefore be an anticipation. 14

It must also be noted that the Patent Office, only after making a close examination of Tuohy’s claim of invention, granted him a patent on the corneal type lens. And there is evidence that the corneal lens met with wide acceptance and success only after Tuohy put it on the market. We, therefore, conclude that the district court’s finding that Tuohy invented the corneal type lens is not clearly erroneous.

“Flash of Creative Genius”

The Supreme Court in Cuno Engineering Corp. v. Automatic Devices Corp., 1941, 314 U.S. 84, 91, 62 S.Ct. 87, 41, 86 L.Ed. 58, set forth the following tests for a patentable device: .

“ * * * the new device, however useful it may be, must neveal the flash ’ of ■ creative genius, not merely the skill of the calling. If it fails, it has not established its right to a private grant on the public domain.” -

However, on July 19, 1952, as part of the revision of Title 35 U.S.C.A. on Pat-énts, 66 Stat. 792, Congress enacted § 103 which provides in part that,’

. “Patentability shall not be nega- . tived by the manner in which the invention was made.”

The’ Reviser’s note interprets this sentence to mean “that patentability as to this requirement, [i.
