Opinion

MEMORANDUM OPINION

SUE L. ROBINSON, District Judge.

I. INTRODUCTION

Plaintiff, The B.F. Goodrich Company (“BFG”), originally filed separate actions against defendants, Aircraft Braking Systems Corp. (“ABS”) and Allied-Signal Incorporated (“Allied”), claiming that the defendants infringed two United States patents relating to aircraft brakes. The two suits were subsequently consolidated. BFG charges defendants with infringing United States Patent Nos. 4,613,017 (’017) and 4,742,895 (’895) (the “Bok patents”, named after their inventor, Lowell Bok). The patents-in-suit disclose a new brake assembly and overhaul technique commonly referred to as “EDL” or extended disk life.

Presently before this Court is Allied’s motion for summary judgment pursuant to Fed. R.Civ.P. 56, in which it claims that the Bok patents are invalid. In support of its argument, Allied relies on section 102(b) of Title 35, United States Code, which bars issuance of a patent if the invention was either on sale or described in a printed publication more than one year prior to filing a patent application. Allied contends that the EDL brakes were both on sale and described in a printed publication more than one year prior to filing the application. 1 Upon review of the parties’ briefs and presentation at oral argument, the Court will deny Allied’s motion for summary judgment.

II. FACTUAL BACKGROUND

For years, most aircraft brakes have been manufactured with a stack of disks (multiple disk brakes) which include a number of rotor and stator disks (“rotors” and “stators”). The traditional design includes rotors which are connected to the aircraft wheels and rotate with them, and stators which are stationary and attached to a brake frame which in turn is attached to the aircraft landing *67 gear. The rotors and stators are positioned in an alternating relationship and are slidable along separate. keyways so they can be pressed against one another by brake pistons. Immediately after touchdown on a runway, the brakes are applied, and the brake pistons push the disks against one another. The friction between the rotors and stators slows the wheels and, hence, the airplane. Wear of the friction surfaces occurs on each landing. This wear occurs on both rotor and stator surfaces, and the portion of each disk that wears away may be referred.to as the “wear portion” or “wear thickness.”

In recent years, aircraft brake manufacturers have found it advantageous to make disks out of carbon rather than steel. While the use of carbon does offer advantages such as lighter weight, it is also expensive and difficult to fabricate. As a consequence, brake designers have attempted for many years to increase the life of the carbon disks, while at the same time lowering the cost of the disks and reducing the weight of the brake-

Prior to the Bok invention, multiple disk carbon brakes were uniformly designed so that each rotor and stator had the same wear thickness and weight. Eventually, these disks wear out and must be replaced. At the time of replacement in a traditional carbon brake, all of the disks are worn out and require replacement or “overhaul.”

In contrast to the traditional brake design, the EDL brakes designed by Mr. Bok are assembled with two groups of disks having different wear thicknesses and, therefore, different weights. This design differs from the prior art in which the rotors and stators shared a uniform wear and thickness. Another distinguishing feature of the EDL brakes concerns the overhaul technique in which only half of the disks (either the rotors or the stators), rather than all, are replaced. Thus, the brake never, either before or after overhaul, has disks with uniform wear thicknesses.

III. DISCUSSION

In moving for summary judgment, Allied presents two arguments that the Bok patents are invalid pursuant to 35 U.S.C. § 102(b): (1) the invention was on sale more than one year before the July 2, 1984 patent application date, and (2) the invention was described in printed publications more than one year before the July 2, 1984 patent application date.

A. Summary Judgment Standard

It is well settled that summary judgment is as appropriate in patent cases as in any other type of case. Johnston v. Ivac Corp., 885 F.2d 1574, 1576-77 (Fed.Cir.1989). The Federal Circuit has affirmed numerous decisions granting summary judgment for patent invalidity, particularly under 35 U.S.C. § 102(b). 2 In the case at bar, the patents at issue are presumed valid and defendant bears the burden of establishing invalidity by clear and convincing evidence. 35 U.S.C. § 282; Intel Corp. v. United States Int’l Trade Commission, 946 F.2d 821, 829 (Fed.Cir.1991).

Federal Rule of Civil Procedure 56(c) provides that a party is entitled to a summary judgment where “the pleadings, depositions, answers to interrogatories and affidavits, if any, show that there is no genuine issue of material fact and that the moving party is entitled to a judgment as a matter of law.” The party moving for summary judgment has the burden of showing that no genuine issue of material fact exists and the Court must view any factual inferences drawn from the evidence in a light most favorable to the non-moving party. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248, 106 S.Ct. 2505, 2510, 91 L.Ed.2d 202 (1986). The district court should only decide the case as a matter of law where the facts are undisputed or “the evidence is so one-sided that it leaves no, room for any reasonable differences of opinion as to any material *68 fact.” Id. However, the mere existence of some evidence in support of the non-moving party will not be sufficient; there must be enough evidence to enable a jury to reasonably find for the nón-móving party. Id. In this case, the facts are not in dispute; rather, the application of the facts to the law is controverted.

B. On-Sale

Section 102(b) of Title 35, United States Code, provides in pertinent part as follows:

A person shall be entitled to a patent unless—
(b) the invention was patented or described in a printed publication in this or a foreign country or in a public use or on sale in this country more than one year prior to the date of the application for patent in the United States....
