Opinion

SIMONS, Circuit Judge.

Some 30 or 35 years ago golf club manufacturers began substituting tubular steel shafts for the conventional hickory shafts in golf clubs. It was thought as disclosed by Knight in his patent No. 976,267, that hickory offered but small resistance to tortional strain, causing the club head to twist upon impact, and so to make the flight of the driven ball uncertain and irregular. Knight, among others, observed, the need .of suppleness in a golf shaft to suit the taste of the individual player, some preferring it to be near the head and others near the middle of the shaft, the “feel” of the club dominating these preferences. [231]*231lie asserted that in a steel shaft the metal may be so distributed that suppleness can be achieved at any desired point.

Earlier it had been found that tubular steel shafts of unvarying diameter were either too stiff to provide the desired “whip,” or, if light enough to be flexible, proved fragile. Knight preferred a straight tapered tube with suppleness near the head, as in the ordinary tapered hickory shaft. The art of steel shaft manufacture developed rapidly, as disclosed by many British and American patents and prior uses, all having for their objectives, points or areas of flexation in the shaft by which length and accuracy of drive was hoped to be obtained and the elusive quality of “feel” given to the club. Undoubtedly some of the improvements marked* meritorious advances in the art, while others furnished mere “talking points” appealing to the type of golfer who, with the hope that springs eternal, periodically seeks to lower his handicap by transactions in the “pro” shop rather than by sweating it out on the practice tee.

This evolution continued so that Cowdery, an executive of the appellee, could justifiably observe, in 1933, in a letter to Vickery, “we have certainly been bewildered with a multiplicity of ideas lately on shafts with different points of flexure. Kroyden are talking it — Ileddon’s are sending out samples, and Wilson’s have also got the same bug — all of them apparently claiming originality. Mr. Walker Hackett, of British Steel Golf Shafts, Ltd., * * * showed us samples of such shafts, also illustrations taken from their British Curved Taper Patents, showing shafts with about every point of whip covered, and any combination of points of whip, covered by their Curved Taper Patents.” Into this art, which the Court of Customs and Patent Appeals in Vickery v. Barnhart, Cust.&Pat.App., 118 F.2d 578, characterized as crowded, came Barn-hart patent No. 2,050,554, issued August 11, 1936, on an application filed October 30, 1934, the claims of which are here in suit. Like those who preceded him, Barn-hart thought it desirable to configure the shaft and proportion the taper so as to produce variations in the “feel” of the club, as a matter of major importance in the minds of discriminating users. The earlier expedients to accentuate flexation had been, he thought, based upon the assumption that it was desirable to progressively decrease the diameter of the shaft, either by continuous tapering or by a stepping-down arrangement from the grip toward the head. His invention, he recites, differs from prior practice in that the shaft is functionally divided into two portions by a region of abrupt transition in diameter which in effect separates the shaft as a whole into two units of flexation, one of which extends from the handle to the medial region, and the other from the medial region to the head, duplicating the taper in different portions of the shaft. It is thereby possible, he thought, to vary the action of the shaft with the resultant “feel” so as to meet individual requirements. The characteristic feature of the invention resides in the fact that a medial bulge or shoulder abruptly increases the diameter of the upper end of the lower shaft portion as compared with the diameter of the lower end of the upper shaft portion, and so affords a division or barrier causing each portion of the shaft to flex in conformity with the requirements of its own configuration. Continuity of action is interrupted by a region of increased stiffness in the medial portion of the shaft, so that flexibility is distributed in a distinctive manner and centered in two separated regions. The Barnhart shaft is accordingly referred to as a shaft having a “reverse taper,” or as being a “step-up shoulder shaft.”

The Barnhart patent was put into interference with an application of Vickery, the appellee’s assignor, which eventually issued as patent No. 2,250,429. The broad claims were awarded to Barnhart and the narrower ones to Vickery. The appellant here contends that Barnhart is entitled to all of the claims. The history of the interference proceeding will not be reviewed. It is sufficiently set forth in Vickery v. Barnhart, supra. It is only necessary to observe, in passing, that the appellants contended in the court below that priority to all claims should have been awarded to Barnhart by reason of new evidence first discovered by Heddon, Barnhart’s licensee, in 1941, after the termination of the interference proceeding. This consisted of an abandoned application filed by Barnhart on April 13, 1926, which the appellants claim disclosed the idea of locating a reverse shoulder in the medial region, and so was proof that Barnhart had the complete invention, long prior to the date of conception, assigned to Vickery. Knowledge of this application the appellants say was suppressed by Barnhart dur[232]*232ing the interference, for the reason later discovered that Barnhart, in 1926, was obligated by contract with parties representing Antioch College, to transfer to them rights in golf club inventions. The district court found it unnecessary to consider the question of priority because of its conclusion that the Barnhart patent disclosed no inventive novelty, and it is to this question that we must first address ourselves.

Barnhart’s idea that the flexibility of the shaft should be concentrated in an area remote from the head of the club, was not new. Long before steel shafts came into general use, it was proposed to achieve this flexibility by thinning the desired part of the wooden shaft in various ways. The Fox British, patent No. 24,144 (1911) shows a wooden shaft tapering both ways from the center, which is the thickest part of the shaft, for the purpose of increasing the “spring” of the shaft, “inasmuch as the spring action commences at a point nearer to the handle than is the case in a club of ordinary construction.” The same idea was used by L. A. Young Company about 1932, for its “bi-taper” steel shafts. Fox may have put the upper area of flexibility too high for best results, but clearly the problem was understood. The Riordan British patent No. 10,431 (1906) shows a shaft thinned in the desired plane so as to increase flexibility in the region of thinning. “Flats” are provided to act as a hinge while the shaft is widened in the opposite plane to avoid weakening it. There is no abrupt shoulder, as in Barnhart, nor is the shaft uniformly circular in cross-section, but it does have multiple areas of varying flexibility. Fox and Riordan worked with wooden shafts, but such suggestion as they present of the desirability of areas of flexibility remote from the head, is not thereby precluded from consideration because mere substitution of materials is not invention.
