Plaintiffs, v. Civ. No.: 1:23-cv-11121-MRG

AB SCIEX LLC,

Defendant.

ORDER ON DEFENDANTS’ MOTION TO DISMISS [ECF No. 37]

GUZMAN, J.

Plaintiffs MSTM, LLC (“MSTM”) and M&M Mass Spec Consulting, LLC (“M&M”) (collectively, “Plaintiffs”) bring this action against Defendant AB Sciex LLC (“Sciex” or “Defendant”), alleging that Sciex, after entering into multiple confidentiality and nondisclosure agreements to evaluate potential collaboration and licensing of Plaintiffs’ patented mass spectrometry ionization technologies, including the Patents-in-Suit and other proprietary information, improperly used those disclosures to develop, manufacture, use, sell, offer for sale, and import mass spectrometry instruments incorporating Plaintiffs’ patented and trade secret technologies without authorization. [See generally Am. Compl., ECF No. 36]. Plaintiffs further allege that Sciex misappropriated trade secrets disclosed under non-disclosure agreements, breached contractual obligations limiting the use of confidential information for licensing evaluation, and unjustly retained economic benefits while refusing to enter into a license agreement. [Id.] Before the Court is Defendant’s Partial Motion to Dismiss for failure to state a claim under Fed. R. Civ. P. 12(b)(6). [Def.’s Mot. Dismiss, ECF No. 37]. Defendant moves the Court to dismiss Counts II-VIII for direct and indirect patent infringement, all causes of action for contributory infringement under Counts I-VIII, and Count XII for unjust enrichment. [Id.] After careful

consideration and oral argument, [ECF No. 64], the Motion to Dismiss, [ECF No. 37] was DENIED by electronic order, [ECF No. 75]. This Memorandum provides the reasoning for the Court’s ruling and supersedes the Court’s previous determination for the unjust enrichment claim. The Motion to Dismiss for Count XII is GRANTED. I. BACKGROUND The following relevant facts are taken primarily from the allegations in Plaintiffs’ Amended Complaint and are accepted as true for purposes of this motion. Ruivo v. Wells Fargo

Bank, N.A., 766 F.3d 87, 90 (1st Cir. 2014) (explaining that a reviewing court “must separate the complaint’s factual allegations (which must be accepted as true) from its conclusory legal allegations (which need not be credited).”) (quotation omitted)). All plausible inferences are made in Plaintiffs’ favor. Id. A. The Patents-in-Suit

Between July 12, 2011, and October 6, 2020, the United States Patent and Trademark Office (“USPTO”) duly and legally issued eight patents relating to mass spectrometry: U.S. Patent Nos. 7,977,629 (“the ’629 Patent”), 9,105,458 (“the ’458 Patent”), 10,679,838 (“the ’838 Patent”), 11,430,648 (“the ’648 Patent”), 9,870,909 (“the ’909 Patent”), 9,552,973 (“the ’973 Patent”), 10,128,096 (“the ’096 Patent”), and 10,796,894 (“the ’894 Patent”) (collectively, the “Patents-in- Suit”). [Am. Compl. ¶¶ 1, 28–35].1 The Patents-in-Suit—all of which are owned or exclusively licensed by Plaintiffs—relate to mass spectrometry, an analytical technique that identifies the structure and chemical properties of molecules. [Id. ¶¶ 2, 35; ECF No. 38 at 2]. Mass spectrometry is a key technology in applications such as drug development, proteomics, metabolomics, chemical

analyses, and pharmaceutical testing. [Am. Compl. ¶ 2]. On July 12, 2011, the USPTO issued the ’629 Patent, entitled “Atmospheric Pressure Ion Source Probe for a Mass Spectrometer,” to inventors Charles Nehemiah McEwen and Richard Garrett McKay. [Id. ¶ 28]. On August 11, 2015, the USPTO issued the ’458 Patent, entitled “System and Methods for Ionizing Compounds Using Matrix-Assistance for Mass Spectrometry and Ion Mobility Spectrometry,” to inventors Sarah Trimpin and Ellen dela Victoria Inutan. [Id. ¶ 29]. On June 9, 2020, the ’838 Patent, and on August 30, 2022, the ’648 Patent were issued to the

same inventors under the same title. [Id. ¶¶ 30–31]. On January 24, 2017, November 13, 2018, and October 6, 2020, respectively, the USPTO issued the ’973 Patent, the ’096 Patent, and the ’894 Patent, each entitled “System and Method for Ionization of Molecules for Mass Spectrometry and Ion Mobility Spectrometry,” to inventors Charles Nehemiah McEwen, Sarah Trimpin, and Vincent Salvatore Pagnotti. [Id. ¶¶ 33–35]. On January 16, 2018, the USPTO issued the ’909 Patent, entitled “Compositions and Methods for Mass Spectrometry,” to inventor Sarah Trimpin. [Id. ¶ 32].2

1 The Patents-in-Suit are attached as exhibits to the Amended Complaint. See Ex. A, ECF No. 36-1; Ex. B, ECF No. 36-2; Ex. C, ECF No. 36-3; Ex. D, ECF No. 36-4; Ex. E, ECF No. 36-5; Ex. F, ECF No. 36- 6; Ex. H, ECF No. 36-8; Ex. I, ECF No. 36-9. 2 The Court notes that paragraph 32 of the Amended Complaint references both the ’648 and ’909 Patents and assumes based on the context of this section that the Plaintiffs intended to refer to ’909 Patent only. As the CEO and co-founder of MSTM, Dr. Trimpin invented the ’458, ’898, ’648, ’838, and ’909 Patents, which relate to matrix-assisted ionization vacuum (“MAIV”) technology. [Id. ¶¶ 68–69, 71]. MSTM’s patented and licensed mass spectrometry technologies, invented by Drs. McEwen, Trimpin, and others, represent the Patents-in-Suit, several of which are nationally

recognized and awarded. [Id. ¶¶ 64–71]. B. The Parties and Their Interests Plaintiff M&M is the owner and assignee of the ’629 Patent and possesses the full and exclusive right to sue and recover damages for infringement thereof, including past, present, and ongoing acts of infringement. [Id. ¶ 28].3 Plaintiff MSTM is the owner and assignee of the ’458,

’838, ’648, and ’909 Patents and possesses the full and exclusive right to sue for and recover damages arising from any infringement, including past, present, and ongoing acts. [Id. ¶¶ 29–32].4 M&M markets and sells the technology known as the Atmospheric Solids Analysis Probe (“ASAP” or “ASAP Probe”) that is embodied in the ’629 Patent and MSTM distributes the ASAP Probe. [Id. ¶¶ 51, 53–54]. The ’973, ’096, and ’894 Patents (collectively, the “Licensed Patents” or “University Patents”), invented by Drs. McEwen, Trimpin, and Pagnotii, have been assigned to the University

of the Sciences (“USciences”) and Wayne State University (collectively, the “Universities”). [Id. ¶ 33].5 Pursuant to an exclusive worldwide license agreement between the Universities and MSTM, the Universities granted MSTM “all substantial rights” in the Licensed Patents, including the exclusive right to enforce, license, and recover damages for infringement. [Id. ¶¶ 33–36 (citing

3 Plaintiff M&M was co-founded by Drs. Charles McEwen and Richard McKay. [Am. Compl. ¶ 4]. 4 Plaintiff MSTM was founded by Drs. Charles McEwen and Sarah Trimpin. [Id. ¶ 5]. Currently, Dr. McEwen serves as the President of MSTM and Dr. Trimpin is the Chief Executive Officer. [Id. ¶¶ 6–8]. 5 Dr. Trimpin is a Professor at Wayne State University. [Id. ¶ 72]. Ex. G (hereinafter “License Agreement”), ECF No. 36-7)]. In August 2015, MSTM amended its operating agreement to provide USciences with an ownership interest in MSTM. [Id. ¶ 39]. On December 12, 2022, and January 13, 2023, respectively, USciences and Wayne State formally acknowledged and consented to MSTM’s exclusive right to assert and enforce the Licensed Patents

against Defendant Waters Corporation. [Id. ¶ 36].
