Solex Laboratories, Inc. v. Graham, 165 F. Supp. 428, 118 U.S.P.Q. (BNA) 438, 1958 U.S. Dist. LEXIS 3705 (S.D. Cal. 1958).

Opinion

TOLIN, District Judge.

This patent infringement litigation concerns but one patent. There are several separately filed cases which have been consolidated for trial. There are different accused structures in the various cases. The patent is not a stranger to this District Court. In the unreported case of Solex Laboratories v. Pacific Contact Laboratories, another Judge of this Court held it valid. The decision was affirmed on appeal. 1 Attorneys for the defendants in the present case have insisted that the former case was but little more than a default. From the entire record on appeal that does not appear to be a correct appraisal of the prior litigation. Although the attorneys in that case are also among the attorneys in the present consolidated cases, the named party defendants are different and the doctrine res judicata accordingly does not apply. The patent in suit was issued to Kevin M. Tuohy and bears Number 2,510,438. It was assigned to plaintiff. The claims read:

“I claim:
“1. A contact lens applicable to the human eye comprising a concavo-convex lens formed of light-transmitting material having a marginal size smaller than the limbus portion of the eye to which it is applicable but larger than the maximum iris opening, said lens having a radius of curvature on its concave side slightly greater than the radius of curvature of the cornea to which it is applied so that radially from the center of the lens there will be a small but gradually increasing clearance for the entry of natural eye fluids between the lens and the cornea,. said lens being ground to correct for visual deficiency.
*430 “2. A contact lens applicable to the human eye comprising a concavo-convex lens formed of light-transmitting material having a marginal size smaller than the limbus portion of the eye to which it is applicable but larger than the maximum iris opening, said lens having a radius of curvature on its concave side slightly greater than the radius of curvature of the cornea to which it is applied so that radially from the center of the lens there will be a small but gradually increasing clearance for the entry of natural eye fluids between the lens and the cornea, said lens being ground to correct for visual deficiency and having a bevel at its marginal edges on the concave side thereof.”

The patent is presumptively valid.

“ * * * The issue of the patent is enough to show, until the contrary appears, that all the conditions under which a discovery is patentable in accordance with the statutes have been met. Hence, the burden of proving want of novelty is upon him who avers it.” 2
“* * * Not only is the'burden to make good this defense upon the party setting it up, but his'burden is a heavy one, as it has been held that ‘every reasonable doubt should be resolved against him.’ * * * ”. 3

Whatever may be said for the prior art hereafter discussed, it appears that before the introduction of .the Tuohy lens, contact lenses for the correction of vision in the human eye were cumbersome and uncomfortable structures to which the user had only a tolerance of brief duration at a given use. There was an interference with normal vision. ■ This was manifested by the appearance of rainbows or halos within the user’s field of vision and clouding of the vision after the lenses had been worn for a short time. These earlier lenses were what have generally been referred to in the optometrical field as scleral lenses. By this was meant that although the portion of the lens employed to correct vision was small, the lens extended beyond the border of the vision correcting area so as to be a glass or plastic structure which extended beyond the cornea with the edges resting on the scleral portion of the eye. The scleral lenses had flanges. The presence of these scleral flanges made such contact lenses very difficult to wear. When in use they pressed on the sclera and covered the sclera to a large extent and tended to restrict the natural blood supply to the eye. They also interfered with the free movement of natural eye fluids, and the eye covered by such a lens was deprived of free circulation of natural eye fluids and the supply of oxygen normally available from the air. A buffer solution compatible with the tissues of the patient was necessarily used. The halos and cloudiness which interfered with the patient’s vision, as above stated, arose from the circumstance that the buffer solution deteriorated rapidly during use. Despite the considerable practical limitation of undertaking to use a scleral lens instead of conventional spectacles, there was some small demand for these lenses because they did enable the user to correct his vision without being patently aided by eye glasses, and the very nearness to the eye was believed in some instances to be beneficial in ameliorating certain pathological conditions. Apparently the custom was for persons willing to undergo the discomfort and inconvenience of a short period of tolerance of the lenses to use them for maxi■mum periods of a very few consecutive hours. In the light of this cumbersome and often painful application and functioning of the pre-Tuohy lenses, Tuohy is corroborated in his insistence that his work was the originally successful corneal lens by the fact that following the in *431 vention disclosed by the patent, a sizeable industry in the manufacture of corneal lenses promptly came into being and those who prescribed glasses for the correction of visual deficiencies commenced to prescribe them with frequency. Use of the scleral lenses declined. The public acceptance was considerable and the corneal lenses enjoyed immediate commercial success whereas the scleral lenses had achieved only occasional tolerance by some unfortunate user whose occupation 4 or pathology drove him to a toleration of the inconvenience, discomfort and visual deficiencies. Had any of the predecessors cited as prior art been able to accomplish the generally satisfactory result of the Tuohy lens, such a structure would, in great probability (in the light of the willingness of the public to accept a contact lens) have been readily accepted. However, the prior art cited against the invention is, for the most part, patently beside the point. Some foreign language publications have been received in evidence. These so meagerly described the structures with which they dealt, or adequately described some widely different device, that those interested in contact lenses for correction of visual deficiencies were not thereby led to create the Tuohy type lens.

That the Tuohy lens rapidly very largely replaced the scleral lenses in the market, is some evidence of successful novelty. 5 The inventor developed an entirely different approach to a solution of the hitherto unsolved problems. He eliminated the scleral flange entirely and manufactured a contact lens which would cover only the cornea.
