THYNGE, United States Magistrate Judge.

1. INTRODUCTION

This is a patent infringement case. Di-gene Corporation (“Digene”) commenced litigation against Ventana Medical Systems, Inc. (‘Ventana”) on November 19, 2001, alleging infringement of U.S. Patent Nos. 4,849,332 (“the '332 patent”) and 4,849,331 (“the '331 patent”). Digene’s '332 patent is embodied in its “HPV products,” which are tests that screen for the presence of the Human Papillomavirus (“HPV”) 35, a virus known to cause cervical cancer. 1 In its complaint, Digene alleges that Ventana infringes the '332 patent by selling HPV tests that were made with cell paste purchased from Beckman and further, that Beckman’s assignment of its right, title and interest to Ventana violates the terms of the CLA. 2 Following the arbi *277 tration proceedings against Beckman, on August 29, 2006, Digene moved for a preliminary injunction to prohibit Ventana from making, using, selling, and offering for sale, reagents that contain HPV 35. 3 On October 6, 2006, Ventana filed its opposition to Digene’s Motion for Preliminary Injunction. 4

II. POSITION OF THE PARTIES

Digene urges that a preliminary injunction is the only method by which it can obtain any benefit from the “right to exclude” Ventana from infringing the patent, especially in light of the fact that the '332 patent expires on May 26, 2007.

A. Likelihood of Success on the Merits

Digene asserts a strong likelihood of succeeding on the merits of its infringement claim. Digene alleges that Ventana does not have a license defense to an infringement claim because the ICDR invalidated the purported assignment by Beck-man of its rights to the '332 patent to Ventana occurring in 2002. 5 Digene propounds that Ventana’s arguments about validity, specifically prior art and enablement, are without merit, noting that an issued patent is presumed valid and that the '332 patent stood unchallenged for nineteen years. Digene also points to evidence that Ventana previously attempted to obtain rights to the '332 patent, rather than challenge its validity.

Ventana, on the other hand, argues that it raises a “substantial question” concerning its license defense; thus, Digene does not have a likelihood of success on the issue of infringement. Ventana claims that the assignment of rights in the '332 patent is valid because the ICDR did not invalidate the Asset Purchase Agreement. In the alternative, Ventana argues that it is not bound by the ICDR award because it was not a party to the proceedings.

B. Irreparable Harm

Digene alleges that it will suffer irreparable harm without an injunction. According to Digene, while the matter was in arbitration, Ventana built a market pres *278 ence by continually infringing the '332 patent, and therefore, Digene’s exclusive position cannot be restored through a damage award after a competitor has entered the marketplace. Digene notes that currently approximately 50 accounts use Ventana’s product rather than Digene’s product.

Ventana counters that there is no irreparable harm because Digene delayed for five years in seeking a preliminary injunction and it dominates the market with respect to HPV sales. Ventana claims that Digene, though it had multiple opportunities to move for injunctive relief, failed to do so. As a result, Ventana maintains that Digene’s delay and repeated failure to seek a preliminary injunction demonstrates an absence of irreparable harm. Moreover, Ventana notes that its sales have little or no effect on Digene’s market share of 85-95% as shown by the evidence. Finally, Ventana claims that by licensing the '332 patent to four other entities, Di-gene has proven that money damages are adequate to compensate for any alleged infringements. 6

Digene, in its reply, challenges Venta-na’s position of no irreparable harm simply because Digene is the dominant market player. Digene argues that because Venta-na took opportunities — potential customers — from Digene, a monetary award alone is insufficient to compensate for lost customer relations, the ability to sell other products to that potential customer, and the impact of pricing negotiations related to having competition in the marketplace. It also claims that Ventana’s allegation that it “sat on its rights” for five years is misleading. Digene posits that not seeking injunctive relief was appropriate based on its reasonable belief that the court lacked jurisdiction to resolve the issues between Digene and Beckman. 7 Further, Digene claims that it was entitled to explore other legal options during the pen-dency of the Beckman arbitration.

In response, Ventana suggests that Di-gene’s argument of lost customer relations is insufficient to establish irreparable harm because Digene has not specifically identified any lost sales. Moreover, Ventana reiterates that Digene has not presented a legitimate excuse for its delay in seeking a preliminary injunction and such a delay indicates the absence of irreparable injury.

III. STANDARD

The grant or denial of a preliminary injunction under 35 U.S.C. § 283 in a patent infringement case is within the sound discretion of the district court. 8 Section 283 permits the court to grant injunctions “in accordance with principles of equity to prevent the violation of any right secured by patent, on such terms as the court deems reasonable.” 9 The moving party must establish four factors to obtain a preliminary injunction: (1) likeli *279 hood of success on the merits of infringement; (2) irreparable harm in the absence of an injunction; (3) consideration of the balance of hardships tipping in its favor; and (4) favorable impact on the public interest. 10

Each of these factors, when taken individually are not dispositive; rather, the district court must weigh each factor against the other factors and against the form and magnitude of the relief requested. 11 The movant, in seeking a preliminary injunction pursuant to § 283, must demonstrate both a reasonable likelihood of success on the merits and irreparable harm. 12 The reasonable likelihood of success on the merits encompasses two components: (1) plaintiff will likely show that its patent is infringed; and (2) any challenges to the validity and enforceability of the patent “lack substantial merit.” 13
