MEMORANDUM OPINION

SUE L. ROBINSON, District Judge.

I. INTRODUCTION

On September 14, 2012, Joao Bock Transaction Services, LLC ("JBTS") filed a complaint against defendant Jack Henry & Associates, Inc. ("Jack Henry"), alleging that certain Jack Henry products, "such as but not limited to its `goDough' and `NetTeller Online Banking' products," infringe U.S. Patent No. 7,096,003 ("the '003 Patent"). (D.I. 1) On December 3, 2012, Jack Henry answered and counterclaimed. (D.I. 6) Presently before the court is JBTS' motion for dismissal of Jack Henry's counterclaims and to strike certain affirmative defenses and background information, filed December 27, 2012 (D.I. 11), and Jack Henry's motion for leave to file amended counterclaim, filed February 12, 2013 (D. I. 21). The court has jurisdiction over this matter pursuant to 28 U.S.C. §§ 1331 and 1338(a).

Jack Henry's answer and counterclaim includes statements such as:

III. STANDARDS OF REVIEW

A. Motion To Dismiss Pursuant To Rule 12(b)(6)

In reviewing a motion filed under Federal Rule of Civil Procedure 12(b)(6), the court must accept all factual allegations in a complaint as true and take them in the light most favorable to plaintiff. See Erickson v. Pardus, 551 U.S. 89, 94 (2007); Christopher v. Harbury, 536 U.S. 403, 406 (2002). A court may consider the pleadings, public record, orders, exhibits attached to the complaint, and documents incorporated into the complaint by reference. Tellabs, Inc. v. Makar Issues & Rights, Ltd., 551 U.S. 308, 322 (2007); Oshiver v. Levin, Fishbein, Sedran & Berman, 38 F.3d 1380, 1384-85 n.2 (3d Cir. 1994). A complaint must contain "a short and plain statement of the claim showing that the pleader is entitled to relief, in order to give the defendant fair notice of what the .. . claim is and the grounds upon which it rests." Bell Atl. Corp. v. Twombly, 550 U.S. 544, 545 (2007) (internal quotation marks omitted) (interpreting Fed.R.Civ.P. 8(a)). A complaint does not need detailed factual allegations; however, "a plaintiff's obligation to provide the `grounds' of his entitle[ment] to relief requires more than labels and conclusions, and a formulaic recitation of the elements of a cause of action will not do." Id. at 545 (alteration in original) (citation omitted). The "[f]actual allegations must be enough to raise a right to relief above the speculative level on the assumption that all of the complaint's allegations are true." Id. Furthermore, "[w]hen there are well-ple[d] factual allegations, a court should assume their veracity and then determine whether they plausibly give rise to an entitlement to relief." Ashcroft v. Iqbal, 556 U.S. 662, 664 (2009). Such a determination is a context-specific task requiring the court "to draw on its judicial experience and common sense." Id.

B. Motion To Strike Pursuant To Rule 12(f)

Federal Rule of Civil Procedure 12(f) states: "The court may strike from a pleading an insufficient defense or any redundant, immaterial, impertinent, or scandalous matter." "As a general matter, motions to strike under Rule 12(f) are disfavored." Fesnak and Assocs., LLP v. U.S. Bank Nat'l Ass'n, 722 F.Supp.2d 496, 502 (D. Del. 2010). "When ruling on a motion to strike, the [c]ourt must construe all facts in favor of the nonmoving party and deny the motion if the defense is sufficient under law. Further, a court should not grant a motion to strike a defense unless the insufficiency of the defense is clearly apparent." Symbol Techs., Inc. v. Aruba Networks, Inc., 609 F.Supp.2d 353, 356 (D. Del. 2009) (internal quotations and citations omitted).

C. Motion For Leave To File Amended Counterclaim

The Federal Rules of Civil Procedure require courts to "freely give" leave to amend "when justice so requires." Fed. R. Civ. P. 15(a)(2). Nevertheless, courts "ha[ve] discretion to deny a motion to amend for reasons of `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.'" Merck & Co., Inc. v. Apotex, Inc., 287 Fed. App'x 884, 888 (Fed. Cir. 2008) (quoting Foman v. Davis, 371 U.S. 178, 182 (1962)). After a pleading deadline has passed, courts have required the movant to also satisfy the more rigorous "good cause" standard of Fed. R. Civ. P. 16(b)(4). See, e.g., E. Minerals & Chems. Co. v. Mahan, 225 F.3d 330, 340 (3d Cir. 2000); ICU Med. Inc. v. RyMed Techs., Inc., 674 F.Supp.2d 574, 578 (D. Del. 2009); Cordance Corp. v. Amazon.com, Inc., 255 F.R.D. 366, 371 (D. Del. 2009).

IV. DISCUSSION

A. Motion to Dismiss Claims "[do] not require `detailed factual allegations,' but ... [demand] more than an unadorned, the-defendant-unlawfully-harmed-me accusation." Iqbal, 556 U.S. at 677 (citing Twombly, 550 U.S. at 555). JBTS contends that Jack Henry's counterclaims fail to state a claim because Jack Henry does not provide sufficient detail to give rise to a plausible claim for relief. (D .I. 12 at 15-16)

The present case, however, is distinguishable from cases such as Internet Media, as there is far more than a bare allegation of wrongdoing in Jack Henry's answer. See Internet Media Corp. v. Hearst Newspapers, LLC, 2012 WL 3867165, at *1 (D. Del. Sept. 6, 2012) (alleging only "[t]he claims of the ... patent are invalid for failing to comply with one or more of the requirements for patentability ... "with no additional facts is insufficient). In the instant action, the counterclaim does not simply state that the patent is invalid; Jack Henry's counterclaim, as JBTS states, refers to "reasons set forth in its Answer." (D. I. 12 at 16) The answer includes numerous details indicating why Jack Henry believes the '003 patent is invalid, a sample of which includes: the '003 patent is a continuation of a patent determined to be invalid (D.I. 6 at 2), the claims are fatally vague "because they do not particularly point out and distinctly claim the subject matter of the invention" (D.I. 6 at 7), and that prior art existed prior to a year before the patent application (D.I. 6 at 6). The court concludes that the counterclaims provide sufficient notice to JBTS and denies its motion to dismiss.

B. Motion To Strike

1. Introductory section and commentary

"Motions to strike are generally disfavored and ordinarily are denied unless the allegations have no possible relation to the controversy and may cause prejudice to one of the parties, or if the allegations confuse the issues." Sun Microsystems, Inc. v. Versata Entm't., Inc., 630 F.Supp.2d 395, 400 (D. Del. 2009). JBTS' cited cases themselves show that where references to prior litigation might have some evidentiary or legal significance, they should not be stricken. See In re DBSI, Inc., 2011 WL 607398, at *3 (D. Del. Feb. 4, 2011) (finding "factual allegations ... related to the adversary proceeding" should not be stricken). See Symbol Techs., Inc., 609 F. Supp. 2d at 359 (holding prefatory comments not incorporated into or related to the answer or counterclaim should be stricken). Here, the introductory material is related to Jack Henry's equitable defenses in a substantive way. Further, JBTS' claims that implying fraud on the PTO in commentary is "scandalous" is incorrect; fraud is a potential defense and, therefore, must be considered relevant to the controversy.3

2. Affirmative Defenses

A motion to strike a defense is not granted "unless it appears to a certainty that ... [the movant] would succeed despite any state of the facts which could be proved in support of the defense." Nokia Corp. v. Apple Inc., 2011 WL 2160904, at *2 (D. Del. June 1, 2011) (citing Greiffv. T.I.C. Enters., L.L.C., 2004 WL 115553, at *2 (D. Del. Jan. 9, 2004) (internal quotations omitted)). Here, Jack Henry's affirmative defenses contain supporting facts. Construing the facts in the light most favorable to Jack Henry, the court declines to strike Jack Henry's affirmative defenses (D.I. 6 at 111119, 21, 23, 24, and 26), as their insufficiency is not clearly apparent. See Symbol Techs., Inc., 609 F. Supp. 2d at 357 (holding claims "not limited to a particular factual situation nor subject to resolution by simple or hard and fast rules" should not be dismissed at early stages of proceedings if some supporting facts exist.). The court denies JBTS' motion to strike.

C. Motion For Leave To Amend Counterclaim

Jack Henry seeks to amend its counterclaim, asserting that the '003 patent is "void, invalid, and uneforceable" and adding more factual details. JBTS opposes the amendment solely on the basis that the answer and counterclaim still contain the same improperly pled, inflammatory, and prejudicial material. The court addressed those arguments above; therefore, the court grants Jack Henry's motion for leave to file an amended counterclaim.

V. CONCLUSION

For the foregoing reasons, the court denies JBTS' motion to strike and dismiss, and grants Jack Henry's motion for leave to file amended counterclaim. Jack Henry's amended answer and counterclaim attached to its motion is deemed filed and served as of the date of this order. (D.I. 21, ex. A) An appropriate order shall issue.
