Opinion

RICH, Circuit Judge.

Max C. McElmurry and White River Technologies, Inc. (WRT) appeal the February 10, 1992 Judgment of the U.S. District Court for the Eastern District of Arkansas, Northern Division, granting a motion for summary judgment filed by Arkansas Power & Light Company (AP & L) and Entergy Corporation. 1 The district court held that there were no relevant or material factual disputes precluding a finding that AP & L holds “shop rights” to certain subject matter claimed in U.S. Patent No. 4,527,714, titled “Pressure Responsive Hopper Level Detector System” (Bowman patent), and thus, as a matter of law, AP & L had not infringed any claim of the Bowman patent. For the reasons set forth below, we affirm.

I.Standard of Review

? WRT’s complaint alleged patent infringement, the jurisdiction of the district court was based at least in part on 28 U.S.C. § 1338(a) (1988). Accordingly, we have jurisdiction over this appeal pursuant to 28 U.S.C. § 1295(a)(1) (1988).

Under the Federal Rules of Civil Procedure, a motion for summary judgment is properly granted only where

the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and the moving party is entitled to judgment as a matter of law.

Fed.R.Civ.P. 56(c). In reviewing the district court’s grant of summary judgment, we must make an independent determination as to whether the standards of Rule 56(c) have been met. Reversal is required if the district court improperly determined any genuine issue of material fact or erred in holding that AP & L was entitled to judgment as a matter of law. Intellicall, Inc. v. Phonometrics, Inc., 952 F.2d 1384, 1387, 21 USPQ2d 1383, 1386 (Fed.Cir.1992).

II.Genuine Issues of Material Fact

In considering AP & L’s motion for summary judgment, the district court was required to view the evidence in the light most favorable to WRT and to draw all reasonable factual inferences in WRT’s favor. AP & L had the burden of demonstrating the absence of any genuine issue of material fact. However, since AP & L supported its motion with three affidavits, deposition testimony, and a Rule 29 Statement of Uncontested Facts based upon these affidavits and testimony, the burden shifted to WRT to come forward with evidence directed to specific facts showing that there was a genuine issue for trial. Hodosh v. Block Drug Co., 786 F.2d 1136, 1141, 229 USPQ 182, 186 (Fed.Cir. 1986), cert. denied, 485 U.S. 1007, 108 S.Ct. 1472, 99 L.Ed.2d 701 (1988); Fed.R.Civ.P. 56(e).

WRT failed to come forward with such evidence, instead choosing to rely upon eonclusory statements and denials in its pleadings. 2 Mere denials and eonclusory statements, however, are not sufficient to establish a genuine issue of material fact. Hodosh 786 F.2d at 1141, 229 USPQ at 186; Fed.R.Civ.P. 56(e). Therefore, we find no error in the district court’s holding that there were no genuine issues of material fact necessitating trial or in the district court’s acceptance of the facts presented by AP & L in its supporting evidence for purposes of analyzing the “shop rights” issue.

III.Shop Rights

A. Background

AP & L hired Harold L. Bowman, the patentee, as a consultant on October 24,1980, to assist in the installation, maintenance and operation of electrostatic precipitators at AP & L’s White Bluff Steam Electric Station (White Bluff) located near Redfield, Arkansas. An electronic precipitator is a device *1579 which removes granular ash particles (fly ash) from the gasses emitted by coal-fired boilers used to generate steam. As fly ash is removed, it is collected in hoppers referred to as precipitator hoppers. Prior to April of 1982, the precipitator hoppers at White Bluff employed a level detector system using a nuclear power source (K-ray system) to detect the level of fly ash in the hoppers.

AP & L was not satisfied with the K-ray system. As a result, in the early part of 1982, Bowman discussed with a Mr. Richard L. Roberts, an AP & L employee, replacing the K-ray system with a new level detector, an initial design of which they drew on a napkin. 3 In the proposed level detector, a vacuum gauge was connected to a pipe inserted and welded into the wall of a precip-itator hopper. If the level of the fly ash collected in the hopper extended above the point where the pipe was inserted into the hopper, the vacuum gauge would no longer indicate that a vacuum existed, as it would if the level of the fly ash were below that point. Thus, by monitoring the vacuum gauge, one could determine whether the fly ash exceeded a certain level in the hopper.

AP & L considered the proposed level detector and, during a power outage in March of 1982, ordered its installation on one hopper at White Bluff for testing purposes. When it proved successful, AP & L ordered that the level detector be installed on a total of sixteen (16) precipitator hoppers at White Bluff. In each case, level detectors were installed both near the bottom and top of the hopper, thus allowing for the detection of the fly ash at two different levels in the hopper. When this system proved successful, AP & L ordered that the level detectors be installed on the remaining one hundred and twelve (112) precipitator hoppers at White Bluff. All costs associated with the installation and testing of the level detector on the one hundred and twenty eight (128) hoppers at White Bluff, including materials and working drawings, were paid by AP & L.

On October 24,1982, Bowman moved from White Bluff to AP & L’s Independence Steam Electric Station (ISES) located near Newark, Arkansas, to assist in the start-up, maintenance and operation of electronic pre-cipitators at that facility. In November of 1982, Bowman formed White Rivers Technology, Inc. with McElmurry and a Mr, Johnny Mitehum, to market certain inventions on which Bowman held patents or was planning to seek patent protection. Bowman filed a patent application on the level detector on February 18, 1983, and the patent-in-suit issued on July 9,1985. At some point prior to its issuance, Bowman assigned his patent rights to WRT.
