Opinion

MEMORANDUM OPINION AND ORDER

KYLE, District Judge.

Introduction

Plaintiff The Toro Company (“Toro”) commenced this action against Defendants McCulloch Corporation and Shop-Vac Corporation (collectively “McCulloch”) alleging McCulloch infringed upon its patent for a portable power blower/vacuum (the “’528 patent”). McCulloch’s Answer and Counterclaim denied infringement and raised affirmative defenses of patent invalidity and un-enforceability. This matter is currently before the Court on McCulloch’s Motion for Summary Judgment on the issue of compliance with the marking requirements set forth in 35 U.S.C. § 287(a). McCulloch claims that Toro is barred from recovering damages for any infringing acts occurring prior to the filing of the Complaint in this suit because Toro’s licensee sold products arising under the ’528 patent and did not mark those products with the ’528 patent number. For the reasons set forth below, the Court will deny McCulloch’s Motion.

Background

The factual background in this matter is fully set forth in the Court’s November 25, 1994 Memorandum Opinion and Order denying McCulloch’s Motion for Summary Judgment with respect to nomnfringement of the ’528 patent and will not be repeated here. The Court will, however, provide a summary and additional supplementation of those facts necessary to resolve the current Motion.

Toro’s blower/vacuum 1 has a removable cover over the air inlet. The ’528 patent discloses and claims a “safety switch” which prevents the motor and impeller from operat *681 ing when the air inlet cover is removed and the impeller’s rotating blades are exposed to the user, but allows the motor and impeller to operate when the cover is secured in place over the air inlet. This safety switch is claimed in independent claim 1 and dependent claims 2-15 of the ’528 patent. (See Def.’s Mem. in Supp. of Mot., Ex. 1.) The ’528 patent also discloses a performance enhancing ring or “pressure ring” invention; this pressure ring is disclosed in independent claims 16-17. The safety switch and the pressure ring are the subjects of McCulloch’s present Motion.

The ’528 patent was issued to Toro on September 22, 1987. In 1988 Black & Decker, Inc. (“Black & Decker”) approached Toro seeking a license for (1) the safety switch disclosed in claim 1 and (2) the pressure ring disclosed in claims 16 and 17 of the ’528 patent. (See Beattie Aff., Ex. B.) On May 23, 1991, Toro granted a license to Black & Decker authorizing it to make, sell, or use devices containing the safety switch. 2 (Def.’s Mem. in Supp. of Mot., Ex. 3.) Toro did not, however, grant Black & Decker a license to make, use or sell devices containing the pressure ring, and explicitly excluded all claims pertaining to the pressure ring from the license’s scope. (Id.)

Black & Decker manufactured and sold blower/vaeuums subsequent to the receipt of this license. McCulloch has presented evidence that Black & Decker sold blower/vacuums beginning in the fall of 1991, (see Ger-stein Aff., Exhs. 4-10; Def.’s Mem. in Supp. of Mot., Ex. 4), and contends that a significant number of Black & Decker blower/vacuums have been sold since that time. Toro concedes that Black & Decker blower/vacuums have been sold prior to its commencement of this action on June 1, 1994, but alleges that McCulloch has not demonstrated that a substantial number of such blower/vacuums were sold during this period. (Pl.’s Reply Mem. in Opp. to Mot. at 7 n. 6.) McCulloch has also presented evidence that some of the Black & Decker blower/vacuums sold during this period do not contain a marking of the ’528 patent number. (Ber-field Aff. ¶ 5; Def.’s Mem. in Supp. of Mot., Ex. 4.)

The parties dispute whether the Black & Decker blower/vacuums sold prior to June 1, 1994, include the safety switch disclosed in claim 1 of the ’528 patent and authorized for manufacture and distribution in the May 23, 1991 license agreement. McCulloch contends that the Black & Decker blower/vaeu-ums contain every element of the safety switch disclosed in claim 1 of the ’528 patent. Toro alleges that, although licensed, Black & Decker did not use its patented safety switch. McCulloch does not allege that the Black & Decker blower/vacuums contain the pressure ring disclosed in independent claims 16 and 17 of the ’528 patent.

In its present lawsuit, Toro accuses McCulloch of infringing upon its patented pressure ring; Toro does not allege that the McCulloch blower/vacuums contain its patented safety switch. Toro claims that it marked the ’528 patent number on all of its patented blower/vacuums shortly after receiving the ’528 patent, and has subsequently continued to properly mark its blower/vacuums without interruption. (See Seegers Aff. ¶¶ 5 — 6; Swain Aff. ¶¶4-7.) Toro further alleges that the only blower/vacuums containing its patented pressure ring which have not been marked are those that have been unlawfully produced by McCulloch and other in-fringers. (Swain Aff. ¶ 6.)

Discussion

I. Standard of Review

Rule 56 of the Federal Rules of Civil Procedure governs motions for summary judgment. Under that Rule:

[summary] judgment shall be rendered forthwith 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 par *682 ty is entitled to a judgment as a matter of law.

Fed.R.Civ.P. 56(c). Summary judgment is to be granted only where the evidence is such that no reasonable jury could return a verdict for the non-moving party. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 250, 106 S.Ct. 2505, 2511, 91 L.Ed.2d 202 (1986).

Initially, the movant bears the burden of bringing forward sufficient evidence to establish that there are no genuine issues of material fact and that the movant 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). In evaluating the movant’s showing, the evidence offered by the non-moving party is to be believed and all justifiable inferences therefrom are to be drawn in a light most favorable to that party. Matsushita Elec. Indus, v. Zenith Radio, 475 U.S. 574, 587, 106 S.Ct. 1348, 1357, 89 L.Ed.2d 538 (1986); Kornblum v.
