Opinion

DECISION AND ORDER

LARIMER, Chief Judge.

This is a patent infringement case. Plaintiff, Laser Diode Array, Inc. (“LDAI”), alleges that it is the holder of United States Patent No. 5,128,951 (“the ’951 patent”), which was issued on July 7, 1992 and is entitled, “Laser Diode Array and Method of Fabrication Thereof.” LDAI alleges that defendant Paradigm Lasers, Inc. (“Paradigm”) has infringed the ’951 patent by virtue of its manufacture, use, sale, and offer for sale of laser diode arrays that infringe one or more claims of the ’951 patent. LDAI seeks damages, injunctive and other equitable relief, declaratory relief, and attorney’s fees and costs.

LDAI has moved to strike Paradigm’s fourth affirmative defense and to dismiss Paradigm’s second and third counterclaims. Paradigm has cross-moved for leave to amend its answer and counterclaims.

FACTUAL BACKGROUND

LDAI is in the business of manufacturing and selling laser diode arrays, which are small devices that are used to generate laser light for a variety of applications. LDAI alleges that it holds the first issued patent to disclose and claim a laser diode array, and that the ’951 patent is a follow-on to that first patent. LDAI claims that the structure that it designed and patented has made the manufacture of laser diode arrays much simpler.

At one time, LDAI and Paradigm did business with each other. Paradigm is in the business of making diode-pumped solid-state lasers, which use laser diode arrays. After its incorporation in 1992, Paradigm contracted with LDAI to mount laser diode bars that Paradigm had purchased into laser diode arrays. Paradigm contends that these arrays were two-dimensional (“2D”) arrays. According to Paradigm, in 1993, it began developing a three-dimensional (“3D”) array that generated a more efficient beam of light than the 2D arrays assembled by LDAI. In February 1995, Paradigm applied for a patent for a 3D system, which was issued on May 28, 1996. Paradigm applied for a second patent on an improved 3D design in March 1995.

Sometime after March 1995, LDAPs president, Arthur A. Karpinski, met with Timothy Irwin, president of Paradigm. According to LDAI, Karpinski arranged this meeting because he had learned that Paradigm was producing laser diode arrays that infringed the ’951 patent. Paradigm contends that Irwin set up the meeting to explain to Karpinski that Paradigm no longer needed LDAPs 2D arrays because Paradigm had developed a superior 3D array. It appears that Karpinski and Irwin may have expressed some disagreement at that meeting about whether Paradigm’s array violated the ’951 patent, but nothing concrete emerged from the meeting other than the fact that Paradigm would no longer be buying arrays from LDAI.

The next significant event occurred in January 1996, when Irwin wrote a letter to Karpinski stating that he had recently been told by someone in the industry that LDAI was claiming that Paradigm was infringing LDAPs patents in some way. Irwin asked Karpinski for his “assurance that you do not hold the view that my company is in any way infringing your company’s patent rights.” Karpinski Affidavit (Attachment A to Plaintiffs Memorandum of Law), Ex. A.

Karpinski responded in a letter dated January 30, 1996. He told Irwin that “[bjased on the views we exchanged during [their mid-1995] meeting, I am sure you can appreciate that I cannot give you the assurance that you request in your letter.” Karpinski Affidavit Ex. B. Some additional correspondence followed, but the parties’ positions remained unchanged. LDAI commenced the instant action on June 12,1996.

DISCUSSION

I. Plaintiff's Motion to Strike, and Defendant’s Motion to Amend, Fourth Affirmative Defense

LDAI moves pursuant to Rule 12(f) of the Federal Rules of Civil Procedure to strike Paradigm’s fourth affirmative defense, which alleges: “On information and belief, through communications between Plaintiff and Defendant, Plaintiff induced Defendant into believing that Plaintiff would not pursue a patent *93 infringement action against Defendant,” and that LDAI is therefore “barred from recovery in this action based on the doctrine of Estoppel.” Answer ¶¶ 12, 13. LDAI contends that these allegations are insufficient to support a defense of estoppel.

In response, Paradigm has moved for leave to amend its answer. The proposed amended answer contains additional factual allegations to support the estoppel defense, stating that at a meeting in early 1995, Irwin disclosed to Karpinski Paradigm’s new 3D array, and that “Karpinski only briefly mentioned his patent, but did not pursue further any allegations of infringement.” The answer further alleges that “[d]uring the several months that followed, Karpinski had several opportunities to assert an infringement claim against Paradigm, but never did,” that “[d]uring that period of silence, Paradigm continued to pour money and resources into the 3D laser diode project to develop the design, manufacture components, and create a market for the new product,” and that “more than one year later, plaintiff commenced this action against Paradigm.” Amended Answer ¶¶ 13-16. Paradigm has also submitted an affidavit of Irwin further detailing these allegations.

LDAI contends that these allegations are still insufficient to support an estoppel defense. LDAI asserts that there is no basis for an allegation of “misleading silence” by LDAI, that there is no indication that LDAI ever indicated to Paradigm that it was dropping its patent infringement claim, and that Paradigm has not alleged that it relied on any statements or silence on LDAPs part.

Motions to strike a defense are not favored by the courts, William Z. Salcer, Panfeld, Edelman v. Envicon Equities, 744 F.2d 935, 939 (2d Cir.1984), vacated on other grounds, 478 U.S. 1015, 106 S.Ct. 3324, 92 L.Ed.2d 731 (1986), and will only be granted “when the defense is insufficient as a matter of law.” Kaiser Aluminum & Chemical Sales, Inc. v. Avondale Shipyards, Inc., 677 F.2d 1045, 1057 (5th Cir.1982), cert. denied, 459 U.S. 1105, 103 S.Ct. 729, 74 L.Ed.2d 953 (1983). See also Index Fund, Inc. v. Hagopian, 107 F.R.D. 95, 100 (S.D.N.Y.1985) (motion to strike defense may be granted “if the defense asserted is clearly insufficient as a matter of law”); cf. Carter-Wallace, Inc. v. Riverton Lab., Inc., 47 F.R.D. 366, 367 (S.D.N.Y.1969) (motion to strike a defense will be denied if defense is sufficient as a matter of law). A motion to strike an affirmative defense will not be granted, therefore, unless it appears to a certainty that the plaintiff would succeed despite any state of the facts which could be proved in support of the defense. Salcer, 744 F.2d at 939.

As stated, the fourth affirmative defense is based upon the theory of equitable estoppel. The Federal Circuit has adopted the following statement of the elements of equitable estoppel as “a reasonable and fairly complete distillation from the case law”:
