Judge Mazzant

MEMORANDUM OPINION AND ORDER

Pending before the Court is Defendant JPMorgan Chase Bank, N.A.’s Opposed Motion for 

Leave to File First Amended Answer and Counterclaims (Dkt. #43). Having considered the 

Motion and the relevant pleadings, the Court finds that the Motion should be GRANTED. 

BACKGROUND

On December 22, 2023, Plaintiff filed a Complaint alleging that Defendant infringed U.S. 

Patent Nos. 8,924,192 (the “’192 Patent”); 9,298,864 (the “’864 Patent”); 9,971,678 (the “’678 

Patent”); 10,353,811 (the “’811 Patent”); and 10,691,579 (the “’579 Patent”) (collectively, the 

“Asserted Patents”) (Dkt. # 1 at pp. 33–40). The Asserted Patents disclose systems for mobile 

application development, testing, and distribution, including network and device simulation as well 

as online marketplaces for content distribution and revenue sharing (See Asserted Patents, 

Abstract). Plaintiff alleges in its Complaint that Defendant knew of and directly or indirectly 

infringed on the Asserted Patents when, for example, “its employees or agents use Apple’s Xcode 

or Google’s Android Studio (and potentially other software development tools) to author mobile 

applications” (Dkt. #1 at pp. 34–35).

On August 5, 2024, Defendant filed its Opposed Sealed Motion for Leave to File First 

Amended Answer and Counterclaims (Dkt. #43). On August 20, 2024, Plaintiff filed its Response 

in Opposition to Defendant’s Motion (Dkt. #47). On August 28, 2024, Defendant filed its Reply 

(Dkt. #54). Then, on September 4, 2024, Plaintiff filed its Sur-Reply (Dkt. #58). 

LEGAL STANDARD

“When a trial court imposes a scheduling order, Federal Rules of Civil Procedure 15 and 

16 operate together to govern the amendment of pleadings.” Tex. Indigenous Council v. Simpkins, 

544 F. App’x. 418, 420 (5th Cir. 2013). Rule 15(a) governs a party’s request to amend its pleading 

before a scheduling order’s deadline to amend passes. See id. Rule 16(b)(4) governs a party’s 

request to amend its pleading after the deadline to amend passes. Sapp v. Mem’l Hermann 

Healthcare Sys., 406 F. App’x. 866, 868 (5th Cir. 2010) (citing S&W Enters., L.L.C. v. SouthTrust 

Bank of Ala., NA, 315 F.3d 533, 536 (5th Cir. 2003)). 

Rule 15(a) provides that a party may amend its pleading once without seeking leave of court 

or the consent of the adverse party at any time before a responsive pleading is served. FED. R.CIV.

P. 15(a). After a responsive pleading is served, “a party may amend only with the opposing party’s 

written consent or the court’s leave.” Id. Rule 15(a) instructs the court to “freely give leave when 

justice so requires.” Id. The rule “‘evinces a bias in favor of granting leave to amend.’” Jones v. 

Robinson Prop. Grp., L.P., 427 F.3d 987, 994 (5th Cir. 2005) (quoting Lyn–Lea Travel Corp. v. Am. 

Airlines, Inc., 283 F.3d 282, 286 (5th Cir. 2002)). But leave to amend “is not automatic.” 

Matagorda Ventures, Inc. v. Travelers Lloyds Ins. Co., 203 F. Supp. 2d 704, 718 (S.D. Tex. 2000) 

(citing Dussouy v. Gulf Coast Inv. Corp., 660 F.2d 594, 598 (5th Cir. 1981)). Whether to grant leave 

to amend “lies within the sound discretion of the district court.” Little v. Liquid Air Corp., 952 

Case 4:23-cv-01137-ALM Document 83 Filed 12/03/24 Page 2 of 6 PageID #: 8193

F.2d 841, 845–46 (5th Cir. 1992). A district court reviewing a motion to amend pleadings under 

Rule 15(a) considers five factors: (1) undue delay; (2) bad faith or dilatory motive; (3) repeated 

failure to cure deficiencies by previous amendments; (4) undue prejudice to the opposing party; 

and (5) futility of amendment. Smith v. EMC, 393 F.3d 590, 595 (5th Cir. 2004) (citing Foman v. 

Davis, 371 U.S. 178, 182 (1962)).

Rule 16(b)(4) provides that a scheduling order issued by the Court “may be modified only 

for good cause and with the judge’s consent.” See Agredano v. State Farm Lloyds, No. 5:15-CV1067-DAE, 2017 WL 5203046, at *1 (W.D. Tex. July 26, 2017) (citing E.E.O.C. v. Serv. Temps Inc., 

679 F.3d 323, 333–34 (5th Cir. 2012)) (stating, “a party seeking leave to amend its pleadings after 

a deadline has passed must demonstrate good cause for needing an extension.”). “The good cause 

standard requires the ‘party seeking relief to show that the deadlines cannot reasonably be met 

despite the diligence of the party needing the extension.’” S&W Enters., L.L.C., 315 F.3d at 535 

(quoting 6A Charles Alan Wright & Arthur R. Miller, Federal Practice and Procedure § 1522.1 (2d 

ed. 1990)). In determining whether good cause exists, courts consider a four-part test: “(1) the 

explanation for the failure to [timely move for leave to amend]; (2) the importance of the 

[amendment]; (3) potential prejudice in allowing the [amendment]; and (4) the availability of a 

continuance to cure such prejudice.” Id. (quoting Reliance Ins. Co. v. La. Land & Expl. Co., 110 

F.3d 253, 257 (5th Cir. 1997)). Only after the movant demonstrates good cause under Rule 16(b)(4) 

does “the more liberal standard of Rule 15(a)” apply to a party’s request for leave to amend. Id. 

ANALYSIS

As a preliminary point, there can be no dispute that Defendant timely moved to amend its 

Answer (See Dkt. #26 at p. 2; Dkt. #43 at pp. 5–6) (establishing that Defendant filed its Motion on 

Case 4:23-cv-01137-ALM Document 83 Filed 12/03/24 Page 3 of 6 PageID #: 8194
4

August 5, 2024, one day before the Scheduling Order deadline to amend pleadings). Further, 

Plaintiff does not allege—nor does the Court believe—that Defendant’s amendment would cause 

undue delay; that Defendant harbored bad faith or dilatory motive in seeking leave to amend; that 

Defendant repeatedly did not cure deficiencies by previous amendments; or that Defendant’s 

proposed amendment would unduly prejudice Plaintiff (See Dkt. #47). Thus, the Court need not 

analyze those factors. The narrow question before the Court, then, is whether the Defendant’s 

proposed amendment to its Answer and Counterclaims would be so futile as to justify denying 

Defendant the opportunity to add an inequitable conduct defense. 

Defendant argues that its amendment is not futile because it sets forth with particularity

the “who . . . what . . . when . . . where . . . why and how” regarding whether Plaintiff engaged in 

inequitable conduct (Dkt. #43 at p. 7). Plaintiff, by contrast, contends that Defendant’s 

amendment “[does] not (and cannot) plausibly plead inequitable conduct under Rule 9(b) and Rule 

12(b)(6)” (Dkt. #47 at pp. 6–7). Specifically, Plaintiff alleges that Defendant did not plausibly plead

materiality, non-cumulativeness, and knowledge or intent to deceive the Patent Office (Dkt. #47 

at pp. 9, 13, 15).

The Court agrees with Defendant. Plaintiff’s critique that Defendant has not adequately 

pleaded an inequitable conduct defense at this stage overlooks that Plaintiff need only establish a 

reasonable inference of inequitable conduct this early in litigation (Dkt. #43 at p. 2) (“No 

depositions have taken place in this matter. Fact and expert discovery do not close until January 

17, 2025 and March 14, 2025, respectively.”). Jordan Kahn Music Co. v. Taglioli, No. 4:21-CV-45, 

2022 WL 178811, at *3 (E.D. Tex. 2022) (“[a] claim has facial plausibility when the [movant] 

pleads factual content that allows the [C]ourt to draw the reasonable inference that the [opposing 

Case 4:23-cv-01137-ALM Document 83 Filed 12/03/24 Page 4 of 6 PageID #: 8195
5

party] is liable for the misconduct alleged.”) (emphasis added). At thisstage, the Court cannot rule 

out the possibility that “discovery will reveal evidence of the necessary claims or elements” (Dkt. 

#54 at p. 4) (quoting id.). This case, in fact, has already demonstrated that point—Defendant did 

not learn about the August 2005 letter purportedly revealing the inventor’s Bandwidth Profiler 

knowledge during prosecution until Plaintiff produced its first document set (See Dkt. #43 at p. 3) 

(quoting Dkt. #43-1 at p. 41) (“On the Flash side, [Macromedia] came close to this concept using 

their Bandwidth Profiler to measure the limitations of connection speeds on an application.”).

Plaintiff separately argues that the letter in question “does not support [Defendant’s] 

inequitable conduct allegations at all” (Dkt. #47 at p. 4). To establish this, Plaintiff asks the Court 

to infer irrelevance from silence—that is, because parties privy to the letter in past litigation chose 

not to allege inequitable conduct, the letter cannot plausibly support such a claim (Dkt. #47 at p. 17) 

(“Moreover, the fact that none of the prior defendants asserted inequitable conduct, even after 

receiving the August 2005 letter, is an objective indication of candor. These three adverse parties 

did not believe they had a plausible basis to allege inequitable conduct, otherwise they would have 

done so.”). Yet, as Defendant points out, an independent party’s strategic choice not to raise 

inequitable conduct is irrelevant to the question of whether a party that has chosen to raise that 

defense did so with sufficient detail, taking all well-pleaded facts as true (Dkt. #54 at p. 6). See SB 

IP Holdings v. Vivint Smart Home, No. 4:20-CV-886, 2022 WL 2761343, *2 (E.D. Tex. 2022) (in 

determining futility, “the Court must accept as true all well-pleaded facts in the plaintiff’s 

complaint and view those facts in the light most favorable to the plaintiff”).

At this juncture, the Court will not surmise why parties in past, related litigation chose not 

to raise an inequitable conduct defense, let alone infer by omission that Defendant’s decision to 

Case 4:23-cv-01137-ALM Document 83 Filed 12/03/24 Page 5 of 6 PageID #: 8196
6

raise one here amounts to baseless, denigrating subterfuge (See Dkt. #58 at p. 6). Thus, the Court 

finds that Defendant has met its burden to show that leave to amend is warranted at this stage of 

litigation. To the extent that Plaintiff believes Defendant has not adequately pleaded inequitable 

conduct in its Amended Answer and Counterclaims, Plaintiff may later move to dismiss 

Defendant’s claim under Rule 12(b)(6). Accordingly, the Court will allow Defendant to amend its 

Answer and Counterclaims and finds that its Motion should be GRANTED. 

CONCLUSION

It is therefore ORDERED that Defendant JPMorgan Chase Bank, N.A.’s Opposed Motion 

for Leave to File First Amended Answer and Counterclaims (Dkt. #43) is hereby GRANTED.

IT IS SO ORDERED.
