Opinion

MEMORANDUM OPINION AND ORDER

CARRIGAN, District Judge.

Plaintiff Dow Chemical Corporation (Dow) commenced this action seeking damages for infringement of U.S. Patent No. 3, 817, 039 (the ’039 patent). Defendants are Eby Mine Service, Inc. (Eby Mine) and two of its officers; R.B. Kemper and Russ Eby. Pursuant to Fed.R.Civ.P. 56, the plaintiff has filed a motion for summary judgment on the issue of patent infringement. Defendants have responded by opposing that motion and by filing a cross-motion for summary judgment pursuant to Fed. R.Civ.P. 56 on the issue of the individual defendants’ liability. Plaintiff has responded by opposing that motion.

The parties have fully briefed the issues and oral argument would not materially facilitate the decision process. Jurisdiction is founded on 28 U.S.C. § 1338(a).

I. FACTUAL AND PROCEDURAL HISTORY.

Subsurface mining operations leave underground voids that, unless backfilled, can result in subsidence of the land above. This case involves a backfilling operation in Wyoming known as the Hanna project.

In 1974, the plaintiff received the ’039 patent for a process of backfilling such voids. The process involves using a closed pressurized system to inject into the void solid materials suspended in water. Sufficient velocity is employed to prevent accumulating deposits of material from blocking the portal through which the slurry enters. The ’039 process permits introduction of substantial amounts of material with very few boreholes. See, Dow Chemical Co. v. United States, 20 Cl.Ct. 623 (1990). 1

II. ANALYSIS.

The alleged infringement presents an issue of fact, but summary judgment is ap *751 propriate where there is no genuine issue of material fact. SRI Internat’l v. Matsushita Elec. Corp. of America, 775 F.2d 1107, 1116 (Fed.Cir.1985). Summary judgment is proper if the pleadings, depositions and affidavits, if any, demonstrate that there is no genuine issue of material fact and that the moving party is entitled to judgment as a matter of law. Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 2552, 91 L.Ed.2d 265 (1986). The party opposing a properly supported summary judgment motion may not rest upon mere allegations of the complaint, but must set forth specific facts showing that .there is a genuine issue for trial. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248-49, 106 S.Ct. 2505, 2510-11, 91 L.Ed.2d 202 (1986).

A. Plaintiffs Motion.

Plaintiff has alleged that the defendants either directly infringed on the ’039 patent in violation of 35 U.S.C. § 271(a), 2 or, alternatively, induced infringement in violation of 35 U.S.C. § 271(b): 3

“The infringement inquiry is broken down into two steps: first, the scope of the claims must be ascertained, and then the trier must decide whether the claims cover the accused device. The latter step, which is the ultimate determination of infringement, is a fact issue, and a motion for summary judgment on that issue should be approached with great care by the district court.” Palumbo v. Don-Joy Co., 762 F.2d 969 (Fed.Cir.1985)

The parties agree that the Claims Court’s construction of the claim should govern this action including the first step in this analysis. The claim at issue here has three elements: (1) use of a suspension to prevent solid materials from blocking the transport conduit, (2) use of a closed pressurized system, and (3) mound formation. 20 Cl.Ct. 623, 642-44 (1990).

The second step requires determining whether the claim described above covers the Hanna project. The first element of the claim clearly was present in the Hanna project because the contract under which Eby Mine performed the backfilling explicitly called for a suspended slurry. The third element, mound formation to fill the void, is merely a result of the first two elements. Id. at 644. Therefore, the only question at issue is whether the second element, a closed pressurized system, was present in the Hanna operation.

Relying on exhibits, depositions and two lengthy affidavits, the plaintiff argues that the Hanna project was indeed a closed system: Although the contract specifications did not call for use of slurry pumps, four such pumps were purchased and used by the defendants. (Kemper depo., p. 48; Eby depo., p. 77-78). The specifications called for pressurized delivery lines from the mixing tank to the borehole. (Kemper ex., p. B00112).: The defendants’ delivery system was closed (Eby depo., p. 82) and pressure tested. (Kemper depo., p. 57). The elbow joint connecting the delivery lines to the borehole was- affixed in a manner allowing it to withstand pressure (Eby depo., p. 62), a refinement unnecessary for a gravity feed system. The borehole was cased to within a few feet of the void. (Kemper ex., p. B00098; Eby depo., p. 58). In addition, the specifications required a pressure relief valve at the borehole. (Kemper, ex. p. B00110). A permanent record log of readings was to be maintained. 4 (Id., p. B00121). The defendants used a pressure gauge capable of measuring both inches of vacuum and pounds of pressure. (Eby depo., p. 66). The effect of all this, the plaintiff argues, was to create a closed pressurized system.

The defendants’ response, lacking citations to the record, is facially deficient to withstand a motion for summary judgment. The specifications called for a pressure re *752 lief valve, topped by a deflector cap and a system to be. run at negative or zero pressure. Ostensibly the presence of the vent meant that the system was open rather than closed. Nonetheless, the plaintiff has presented evidence through affidavits that the system could, and did, operate under pressure. Deflector caps were placed on the vent to direct the flow of material spewing out of the vent. Defendants have not responded to these affidavits except to call them conclusory and suggest that a question of fact still exists.

“[T]here is no issue for trial unless there is sufficient evidence favoring the nonmoving party for a jury to return a verdict for that party.”
