Opinion

MEMORANDUM OPINION

SUE L. ROBINSON, Chief Judge.

I. INTRODUCTION

On November 24, 2003, plaintiff IMX, Inc. (“IMX”) filed this action against defendant LendingTree, LLC (“Lending-Tree”), alleging infringement of U.S. Patent No. 5,995,947 (“the ’947 patent”).

Currently before the court are the parties’ motions for summary judgment with regard to infringement and invalidity. (D.I. 155, 163, 166) On September 8, 2005, the court heard oral arguments on these motions. The court has jurisdiction over these matters pursuant to 28 U.S.C. § 1338.

*483 II. BACKGROUND

The ’947 patent generally relates to “a method and system for trading loans in real-time by making loan applications, such as home mortgage loan applications, and placing them up for bid by a plurality of potential lenders.” ’947 patent, abstract. The ’947 patent was originally filed as Application 08/928,559 on September 12, 1997 and was granted on November 30, 1999.

Claims 2-18 of the ’947 patent depend from claim 1, 1 while claims 20-38 of the ’947 patent depend from claim 19. 2 In an order which has issued concurrently with this memorandum opinion, the court has construed the disputed terms “loan application” and “bid” as used in the limitations of several of these claims.

The accused system, the LendingTree Exchange, is an online system designed to connect borrowers to lenders for the purpose of exchanging loan products. 3

III. STANDARD OF REVIEW

A court shall grant summary judgment only if “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 that the moving party is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(c). The moving party bears the burden of proving that no genuine issue of material fact exists. See Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 586 n. 10, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986). “Facts that could alter the outcome are ‘material,’ and disputes are ‘genuine’ if evidence exists from which a rational person could conclude that the position of the person with the burden of proof on the disputed issue is correct.” Horowitz v. Fed. Kemper Life Assurance Co., 57 F.3d 300, 302 n. 1 (3d Cir.1995) (internal citations omitted). If the moving party has demonstrated an absence of material fact, the nonmoving party then “must come forward with ‘specific facts showing that there is a genuine issue for trial.’ ” Matsushita, 475 U.S. at 587, 106 S.Ct. 1348 (quoting Fed.R.Civ.P. 56(e)). The court will “view the underlying facts and all reasonable inferences therefrom in the light most favorable to the party opposing the motion.” Pa. Coal Ass’n v. Babbitt, 63 F.3d 231, 236 (3d *484 Cir.1995). The mere existence of some evidence in support of the nonmoving party, however, will not be sufficient for denial of a motion for summary judgment; there must be enough evidence to enable a jury to reasonably find for the nonmoving party on that issue. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 249, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). If the nonmoving party fails to make a sufficient showing on an essential element of its case with respect to which it has the burden of proof, the moving party is entitled to judgment as a matter of law. See Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986).

IV. DISCUSSION

A. Infringement

A patent is infringed when a person “without authority makes, uses or sells any patented invention, within the United States ... during the term of the patent.” 35 U.S.C. § 271(a)., A court should employ a two-step analysis in making an infringement determination. Markman v. Westview Instruments, Inc., 52 F.3d 967, 976 (Fed.Cir.1995). First, the court must construe the asserted claims to ascertain their meaning and scope. Id. Construction of the claims is a question of law subject to de novo review. See Cybor Corp. v. FAS Techs., 138 F.3d 1448, 1454 (Fed.Cir.1998). The trier of fact must then compare the properly construed claims with the accused infringing product. Markman, 52 F.3d at 976. This second step is a question of fact. See Bai v. L & L Wings, Inc., 160 F.3d 1350, 1353 (Fed.Cir.1998). The patent owner has the burden of proving infringement and must meet its burden by a preponderance of the evidence. SmithKline Diagnostics, Inc. v. Helena Laboratories Corp., 859 F.2d 878, 889 (Fed.Cir.1988) (citations omitted).

Literal infringement occurs where each limitation of at least one claim of the patent is found exactly in the alleged infringer’s product. Panduit Corp. v. Dennison Mfg. Co., 836 F.2d 1329, 1330 n. 1 (Fed.Cir.1987). An accused product that does not literally infringe a claim may still infringe under the doctrine of equivalents. For there to be infringement under the doctrine of equivalents, the accused product or process must embody every limitation of a claim, either literally or by an equivalent. See Sextant Avionique, S.A. v. Analog Devices, Inc., 172 F.3d 817, 826 (Fed.Cir.1999); Warner-Jenkinson Co. v. Hilton Davis Chem. Co., 520 U.S. 17, 41, 117 S.Ct. 1040, 137 L.Ed.2d 146 (1997). An element is equivalent if the differences between the element and the claim limitation are “insubstantial.” Zelinski v. Brunswick Corp., 185 F.3d 1311, 1316 (Fed.Cir.1999). One test used to determine “insubstantiality” is whether the element performs substantially the same function in substantially the same way to obtain substantially the same result as the claim limitation. Graver Tank, 339 U.S. at 608, 70 S.Ct. 854.
