United States Court of Appeals, Federal Circuit.

Before FRIEDMAN, Circuit Judge, JACK R. MILLER, Senior Circuit Judge, and NIES, Circuit Judge.

PER CURIAM.

DECISION

Pacific Technica Corporation (Patec) appeals from the judgment of the United States Claims Court in Pacific Technica Corporation v. United States, 3 USPQ2d 1168 (Cl.Ct.1986), holding the government not liable under 28 U.S.C. Sec. 1498(a) (1982) for use of inventions claimed in U.S. Patent Nos. 3,714,900 ('900) and 3,786,760 ('760), which Patec owns by assignment from the inventor, Fritz K. Feldmann. With respect to the '900 patent (sabot patent), the court held that all claims were invalid for anticipation or obviousness but that, if valid, the United States had a limited license. The parties agree that if the government has a license it is not limited. With respect to the '760 patent (band patent), the court held the asserted claims invalid by reason of an on sale bar within the meaning of 35 U.S.C. Sec. 102(b) (1982). We affirm the court's ruling that the government has a license under the '900 sabot patent and that the government established the invalidity of the '760 band patent claims. We vacate the portion of the judgment holding that the government's license is limited and, because we do not address the issue, that the '900 patent is invalid. Thus, we affirm in part and vacate in part.

OPINION

* The technology at issue involves spin-stablized sabot projectiles, or ballistics comprised of a subcaliber penetrator (core) and a discardable encasing sabot. Feldmann formed Patec to develop such technology, and the inventions disclosed in the '900 and '760 patents followed. The '900 patent claims a sabot projectile having a body which separates into petals and opens like an umbrella from its rear toward its front under centrifugal spin and overtaking muzzle gas forces. The '760 patent claims a band extending beyond the diameter of the projecting body to engage the gun barrel grooves and impart stabilizing spin to the projectile, and to dam high pressure powder gases behind the band to maximize propellant forces.

II

In March 1967, at the suggestion of the government, Feldmann submitted a proposal to the United States Army to develop a new armor-piercing discarding sabot projectile which was either spin-stabilized or fin-stabilized. On June 27 and August 10, 1967, the Army saw test firings by Patec of a spin-stabilized projectile and on August 22-24, 1967, Feldmann gave a presentation assisted by slides, during which he discussed his spin-stabilized discarding sabot approach. On November 9, 1967, the Army then issued a contract (projectile contract) to Patec to fund development of a projectile. Feldmann filed the '900 application on August 29, 1969. The term of the Army's projectile contract ended in October 1970. Patec states that its work ended with the filing of a report, however, in February, 1969.

Patec contends that the government has no license under the '900 patent because the inventor reduced the invention to practice by August 1967 before entering the contract in November 1967. The parties agree that, if the claimed invention was reduced to practice during the projectile contract, then the government is entitled to an unlimited license under the patent.1

* Patec argues that the government failed to carry its burden of proof that the sabot invention was reduced to practice during the Army contract. More particularly, Patec asserts that the government had to prove that Patec's tests in June and August, 1967, which it asserts reduced the invention to practice, did not constitute such reduction. Contrary to Patec's view, the government did not have a specific burden to prove that negative. The government put forth its evidence of development under the contract, Patec submitted its evidence of reduction to practice before the contract date, and the court made a decision on the basis of all of the evidence that the government had established facts which lead to the legal conclusion that a reduction to practice occurred after the contract date. Also, in view of the manner in which the parties framed the issue, the court did not have to identify with more particularity the date on which the first actual reduction to practice occurred. The issue of whether evidence establishes that reduction to practice occurred after contract work had ended is not argued in the appeal; moreover, as far as we can determine, it was not raised below. The only question to be decided was, therefore, whether reduction to practice occurred before the contract date.

On that issue, the trial court found that spin-stabilizing developments were made during the contract as evidenced by Patec's own monthly reports to the government on such work; that such work was funded, at least in part, by the government under the contract; that such work was encompassed by the contract; and that such work led to a reduction to practice of the claimed invention under the contract. None of the court's factual findings are clearly erroneous and they lead, at least prima facie, to the conclusion that the government has a license under the '900 patent. As explained below, we are unpersuaded that the prima facie case is overcome by Patec's arguments of error by the trial court in reaching that conclusion.
