Opinions

MARKEY, Chief Judge.

Appeal from a judgment of the U.S. District Court for the Central District of California holding that claims 1, 2, and 11 of U.S. Patent 3,566,667 (Hagerty patent) are invalid, and that William K. Hagerty (Hagerty) did not commit fraud on the Patent and Trademark Office (PTO). We affirm.

BACKGROUND

The Hagerty patent, for which the application was filed on October 28, 1968, and which issued on March 2,1971, discloses and claims a vehicle frame straightening device, best illustrated in Fig. 1:

[1147]*1147[[Image here]]

Chain 30, one end of which is connected to the frame to be straightened, passes over fulcrum pulley 25, idler pulley 45, and force pulley 55. It is firmly fastened near the front legs of posts 11 and 12. Yoke 56, carrying force pulley 55, travels in the direction of arrow 57, in response to a power ram 60, to cause the force pulley 55 to rotate and exert a pull on chain 30. A U-bar 37, attached to the hub which supports the fulcrum pulley 25, receives an anchor chain 32 which is fastened to the floor. Spaced openings 18,19, and 20 allow adjustment of the fulcrum pulley and U-bar 37 to accommodate pulls at various heights.

Hagerty and Charles J. Kuhn (Kuhn) were once co-workers. Kuhn showed Hagerty an anchor post used as an anchor chain tie-down in April of 1967, and a post (Kuhn post) for straightening frames in July of 1967. The Kuhn post is shown in Kuhn’s Exhibit 165:

[1148]*1148Kuhn filed a patent application on the Kuhn post on June 20, 1968, and received U.S. Patent 3,589,680 on June 29, 1971.

In September 1972, Kuhn filed a reissue application copying claims from, and requesting an interference be declared with, the Hagerty Patent and U.S. Patents 3,612,-482 (Eck) and 3,566,666 (Berendt). An interference proceeding between Kuhn’s reissue application and the Eck and Berendt patents was terminated without effect here. The Kuhn-Hagerty interference was settled by an agreement granting Kuhn a non-exclusive license under the Hagerty patent.

Kansas Jack, as assignee, sued Kuhn on ■ February 12, 1979, for infringement of the Hagerty patent. Kuhn conceded infringement of claims 1, 2, and 11, but pled the license as an affirmative defense.1

A trial limited to the license defense was held in January 1980. The trial judge rejected the defense because the license limited Kuhn to making, using, and selling the device Kuhn was making at the time that it was executed. That device was not the accused device Kuhn was marketing when sued.

After trial on the remaining issues, Judge Robert J. Kelleher entered a Memorandum of Decision and Order holding claims 1, 2, and 11 of the Hagerty patent invalid under 35 U.S.C. § 1032 in view of: (1) the Kuhn post and U.S. Patent 1,785,923 (Wade) or U.S. Patent 3,492,855 (Wylie); (2) the Kuhn post and Eck, and Wade or Wylie; (3) U.S. Patent 1,810,680 (Rothgarn); (4) Rothgarn and U.S. Patent 1,553,609 (Grau); and (5) Wylie or Eck and U.S. Patent 3,340,720 (Chartier) or the Kuhn post.

Judge Kelleher further held that Kuhn had not established that Hagerty committed fraud on the PTO.

Kansas Jack’s appeal attacks the holding of invalidity. In a separate appeal, Kuhn attacks (1) the holding of no fraud, (2) a finding of commercial success, and (3) the court’s refusal to allow presentation of “prior use” and “on sale” defenses under 35 U.S.C. § 102. Having prevailed on the issue of validity, to which attacks 2 and 3 relate, Kuhn has no standing to make those attacks by way of appeal.

ISSUES

Whether the trial judge erred in holding (1) that claims 1, 2, and 11 are invalid under [1149]*1149§ 103; or (2) that Hagerty did not commit fraud on the PTO.

OPINION

1. Validity

In resolving the obvious/nonobviousness issue, Judge Kelleher looked to the three factual determinations (scope and content of prior art, differences between prior art and claimed invention, and level of ordinary skill in the art) set forth in Graham v. John Deere Co., 383 U.S. 1, 17, 86 S.Ct. 684, 693, 15 L.Ed.2d 545, 148 USPQ 459, 467 (1966). Kansas Jack challenges here not those determinations, but the legal conclusion based on them.

The relevant prior art includes the Kuhn post, and the patents to Wade, Wylie, Eck, Rothgarn, Grau, and Chartier.

The Kuhn post, supra, is a free standing post connected to the load through the pulling chain. Force is provided by a hydraulic ram. A vertically adjustable fulcrum pulley changes the direction of the force. An anchor chain is connected to the floor.

Wade discloses a frame straightening device having a post rigidly secured to a horizontal bottom member. Force is provided by a turnbuckle which connects a car frame to the post through a clevis and pivot pin. A rod connects the pivot pin to a floor anchor.

Wylie discloses a frame straightening device including a post connected to a car frame through a pulling chain. A hydraulic ram is mounted on the post and an anchor chain is connected to the post, to balance the force of the pulling chain and thus eliminate bending moments (forces tending to overturn the device). Vertical adjustment on the post of the ram and chains permits pulls at various heights.

Eck discloses a frame straightening device having a hydraulic ram and a vertically adjustable fulcrum pulley mounted on a post. The pulley receives a pulling chain tensioned by actuating the ram.

Rothgarn discloses a frame straightening device having a hydraulic ram for extending a force pulley at the top of the device. A fulcrum pulley changes the direction of the force. The pulling cable is the only connection between the device and the load.

Grau discloses a hoisting and pulling tool, including a windlass mounted on top of a frame. A fulcrum pulley changes the direction of force and a grapple connects the pulley to a fixed object.

Chartier discloses a frame straightening device having a hydraulic ram mounted on a post and pulling a chain. The chain passes over a fulcrum pulley to change the direction of force. The height of the ram and fulcrum pulley is adjustable.

The Kuhn post, Wade, Wylie, and Eck were found more pertinent than the prior art cited by the PTO.

Judge Kelleher found the differences between the Kuhn post and the claimed invention were two: (1) Hagerty relocated the hydraulic ram from the chain to the post; and (2) Hagerty connected the anchor chain close to the fulcrum pulley, to eliminate bending moments. Difference (1) is disclosed by Wylie, Eck, and Chartier. Difference (2) is disclosed by Wylie, Wade, and Grau.

Judge Kelleher found the level of ordinary skill in the art to be that of a mechanically skilled individual familiar with the design of devices in the industry.
