Opinion

MEMORANDUM OPINION

LATCHUM, Senior District Judge.

I. FACTS

Plaintiff, E.I. duPont de Nemours & Company (“DuPont”) brought this patent infringement action against defendants Phillips Petroleum Company and Phillips Chemical Company (collectively “Phillips”). The patent-in-suit relates to interpolymers described in U.S. Patent 4,076,698 and directed to copolymer resins of ethylene with an alpha-olefin containing five to eighteen carbon atoms.

Pending before this Court is DuPont’s motion under Fed.R.Civ.P. 15(a) for leave to amend its previously amended complaint to add an additional defendant, Phillips Driscopipe, Inc. (“Driscopipe”), a wholly-owned subsidiary of defendant Phillips Pe *312 troleum Company. 1 Although DuPont states in its opening brief that its motion to amend stems from Phillips’ refusal to produce any documents in the possession, custody or control of Driscopipe, 2 DuPont’s counsel at oral argument represented to the Court that it wished to join Driscopipe as a defendant to enable DuPont to potentially hold Driscopipe liable for any lost profit damages caused by sales of pipe containing the allegedly infringing copolymers. 3

Discovery in this case has been extensive and divided into two stages. The first stage concerned validity and enforceability and was closed by Court order on October 31, 1984. 4 This case is now in the second stage of discovery regarding the issues of damages and infringement. Additionally, no trial date has been set in this matter.

II. MOTION FOR LEAVE TO AMEND

Fed.R.Civ.P. 15(a) provides in pertinent part:

(a) Amendments. A party may amend his pleading once as a matter of course at any time before a responsive pleading is served ... Otherwise a party may amend his pleading only by leave of court or by written consent of the adverse party; and leave shall be freely given when justice so requires.

Since Phillips has filed a responsive pleading, 5 leave of Court is necessary.

In the seminal case construing Rule 15(a), Foman v. Davis, 371 U.S. 178, 83 S.Ct. 227, 9 L.Ed.2d 222 (1962), the Supreme Court expounded on the phrase dictating that “leave [to amend] shall be freely given when justice so requires.” The Court opined:

In the absence of any apparent or declared reason — such as undue delay, bad faith or dilatory motive on the part of the movant, repeated failure to cure deficiencies by amendments previously allowed, undue prejudice to the opposing party by virtue of allowance of the amendment, futility of amendment, etc. — the leave sought should, as the rules require, be “freely given.” Of course, the grant or denial of an opportunity to amend is within the discretion of the District Court, but outright refusal to grant the leave without any justifying reason appearing for the denial is not an exercise of discretion; it is merely abuse of that discretion and inconsistent with the spirit of the Federal Rules.

Id. at 182, 83 S.Ct. at 230.

It is axiomatic that the grant or denial of leave to amend the pleadings pursuant to Rule 15(a) is within the discretion of the trial court. Zenith Radio Corp. v. Hazeltine Research, Inc., 401 U.S. 321, 330, 91 S.Ct. 795, 802, 28 L.Ed.2d 77 (1971). Since Rule 15(a) prescribes a liberal policy for granting leave to amend, U.S. v. Hougham, 364 U.S. 310, 316, 81 S.Ct. 13, 18, 5 L.Ed.2d 8 (1960), this Court must examine what prejudice, if any, Phillips or Driseopipe would suffer if leave to amend is granted.

*313 Phillips and Driscopipe advance two main arguments in opposing DuPont’s motion for leave to amend. At the outset, Phillips argues that DuPont is barred by laches and estoppel from amending its complaint. Second, it is contended that Phillips and Driscopipe will be prejudiced by the amendment because this litigation has been ongoing for nearly four years. It is also argued that Driscopipe should be afforded additional discovery on validity and enforceability if DuPont’s motion to amend is granted.

A. Laches and Estoppel

The equitable doctrine of laches, as applied to patent infringement lawsuits, prescribes that if the patentee unduly delays filing its infringement claim, then the patentee is barred from recovering damages for infringements prior to the filing of the lawsuit. A. C. Aukerman Co. v. Miller Formless, Co., 693 F.2d 697, 699 (7th Cir. 1982). To prevail on a laches defense, the alleged infringer must show that the patentee’s delay was unreasonable, inexcusable, and materially prejudicial. Id.; Studiengesellschaft Kohle v. Eastman Kodak Co., 616 F.2d 1315, 1325-26 (5th Cir.), cert. denied, 449 U.S. 1014, 101 S.Ct. 573, 66 L.Ed.2d 473 (1980). Additionally, a six-year delay from the date of the first known alleged infringement is presumptively unreasonable. 6 Leinoff v. Louis Milona & Sons, Inc., 726 F.2d 734, 741 (Fed.Cir.1984). See 35 U.S.C. § 286 (1982).

In contrast, the equitable doctrine of estoppel, if established, precludes all relief for infringement, including relief for alleged infringements that occur after the suit is initiated. A. C. Aukerman, 693 F.2d

at 701. To prevail on the doctrine of estoppel, defendants must demonstrate that the two elements of laches are present, in addition to affirmative conduct by DuPont inducing the belief that it had abandoned its claims against Driscopipe and detrimental reliance by Driscopipe. Young Engineers, Inc. v. U.S. Intern. Trade Com’n, 721 F.2d 1305, 1317 (Fed.Cir.1983).

The patent-in-suit was issued to DuPont on February 28, 1978, 7 approximately seven and one-half years after the patent was issued.
