MEMORANDUM OPINION AND ORDER Before the Court is Plaintiff/Counter-Defendant DPF Alternatives, LLC and Counter- Defendants (collectively, “DPF”)’s Motion to Dismiss Defendant/Counter-Plaintiff DET Diesel Emission Technologies, LLC (“DET”)’s counterclaims (Doc. 140) and Counter-Defendant RTR

DPF LLC (“RTR”)’s Motion to Dismiss (Doc. 135). For the following reasons, the Court DENIES both Motions. I. BACKGROUND DPF, the plaintiff in this case, asserts Lanham Act and antitrust claims, while the defendant, DET, asserts patent infringement and misappropriation of trade secrets counterclaims against DPF

and numerous Counter-Defendants. Only DET’s counterclaims are at issue in this Order. DET provides products and services for diesel engines. It creates “products and methods” to replace or install diesel particulate filters. Doc. 128, Answer, 19 ¶ 18.1 Diesel particulate filters remove diesel particulate matter from diesel engines. Id. DET has developed its technology and techniques for over two decades, and, during this time, DET never shared its intellectual property

with anyone outside the company. Id. at 20 ¶ 19. In 2019, DET developed its “Recore” technology, which “allows for the quick removal” of a diesel filter’s old core, while also making it much easier to install a new diesel filter core. Id. at 20 ¶ 21. DET obtained U.S. Patent No. 12,048,920 (“the ‘920 Patent”) for the Recore technology called “System and Process for Replacing a Core of Diesel Emission Control Device,” and DET also believes that its Recore technology contains numerous trade secrets. Id. at 20–21 ¶¶ 24–25.

1 DET re-uses paragraph numbers in its Answer and Counterclaims (Doc. 128). When the Court cites DET’s pleadings, the Court will cite both the page and paragraph numbers. DET licensed its Recore technology to third parties in 2022 and 2023. Id. at 20 ¶ 23. Before accessing DET’s proprietary materials, the licensees were required to sign confidentiality agreements. Id. These confidentiality agreements prohibited the licensees from sharing DET’s intellectual

property with any party. Id. at 21 ¶ 30. Several of DPF’s franchisees, the Counter-Defendants in this lawsuit, signed licensing agreements with DET to use the Recore technology. Id. at 22 ¶¶ 31–32. DPF did not sign such an agreement. See id. However, through its franchisees, DPF gained access to the Recore technology’s trade secrets, in violation of the confidentiality agreements that the franchisees signed. Id. at 22 ¶ 33.

DPF ultimately developed a device called “New Core” that also replaces old cores in diesel filters. Id. at 24 ¶ 43. DET alleges that the New Core device infringes the ‘920 Patent and that DPF misappropriated DET’s trade secrets to develop the device. DET asserts claims for direct patent infringement, indirect patent infringement, and misappropriation of trade secrets under Texas and federal law. Id. at 23–53 ¶¶ 38–97. DPF moves to dismiss all four claims for failure to state a claim. Doc. 140, Mot. Dismiss, 1. The Court considers the Motion below.

II. LEGAL STANDARD Under Federal Rule of Civil Procedure 8(a)(2), a complaint must contain “a short and plain statement of the claim showing that the pleader is entitled to relief.” Rule 12(b)(6) authorizes a court to dismiss a plaintiff’s complaint for “failure to state a claim upon which relief can be granted.” FED. R. CIV. P. 12(b)(6). In considering a Rule 12(b)(6) motion to dismiss, “the Court must accept all

well-pleaded facts as true, and view them in the light most favorable to the plaintiff.” Walker v. Beaumont Indep. Sch. Dist., 938 F.3d 724, 735 (5th Cir. 2019) (alteration omitted) (citation omitted). But the Court will “not look beyond the face of the pleadings to determine whether relief should be granted based on the alleged facts.” Spivey v. Robertson, 197 F.3d 772, 774 (5th Cir. 1999). To survive a motion to dismiss, plaintiffs must plead “enough facts to state a claim to relief

that is plausible on its face.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007). “Threadbare recitals of the elements of a cause of action, supported by mere conclusory statements, do not suffice.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). “A claim has facial plausibility when the plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Id. “The plausibility standard is not akin to a ‘probability requirement,’ but it asks for more than a sheer possibility that a defendant has acted unlawfully.” Id. (quoting

Twombly, 550 U.S. at 556). When well-pleaded facts fail to meet this standard, “the complaint has alleged—but it has not shown—that the pleader is entitled to relief.” Id. at 679 (alteration omitted) (citation omitted). III. ANALYSIS The Court first DENIES AS MOOT RTR’s Motion to Dismiss because RTR joined DPF

and the other Counter-Defendants’ Motion to Dismiss. The Court then DENIES DPF’s Motion to Dismiss in its entirety. A. The Court Denies RTR’s Motion to Dismiss as Moot. RTR originally filed its own Motion to Dismiss DET’s counterclaims. Doc. 135, Mot. Dismiss, 1. DPF then filed a Motion to Dismiss on behalf of all Counter-Defendants, including RTR, because their lead counsel “learn[ed] . . . that undersigned counsel will and does represent all counter-defendants.” Doc. 140, Mot. Dismiss, 1. The Motions are largely identical. Compare Doc. 135, Mot., with Doc. 140, Mot. DPF also said that its Motion to Dismiss amends RTR’s Motion to Dismiss. Id. Accordingly, the Court denies as moot RTR’s Motion to Dismiss. B. The Court Denies DPF’s Motion to Dismiss in its Entirety.

DET asserts four counterclaims: (1) direct patent infringement; (2) indirect patent infringement; (3) misappropriation of trade secrets in violation of Chapter 34A of the Texas Civil Practices and Remedies Code; and (4) misappropriation of trade secrets in violation of 18 U.S.C. § 1836. Doc. 128, Answer, 23–53 ¶¶ 38–97. DPF moves to dismiss all four claims. Doc. 140-1, Br. Mot., 2. The Court addresses each of DET’s claims in turn. 1. DET Stated a Direct Patent Infringement Claim.

DET adequately alleged each element of a direct patent infringement claim. As a preliminary matter, the Court applies the Federal Circuit’s binding precedent to the “substantive issues of patent law” arising out of DET’s claim for direct patent infringement.
