STATE OF NORTH CAROLINA IN THE GENERAL COURT OF JUSTICE SUPERIOR COURT DIVISION

DURHAM COUNTY 21CVS004094-310

UNITED THERAPEUTICS CORPORATION and LUNG BIOTECHNOLOGY PBC, ORDER AND OPINION ON

Plaintiffs,

DEFENDANT LIQUIDIA

TECHNOLOGIES, INC.’S MOTION v.

FOR SUMMARY JUDGMENT

LIQUIDIA TECHNOLOGIES, INC.

[PUBLIC] 1

and ROBERT ROSCIGNO,

Defendants.

1. Dr. Robert Roscigno (Roscigno) spent a decade working with United Therapeutics Corporation (UTC) to develop a therapy for pulmonary arterial hypertension (PAH) using the drug treprostinil. When he resigned in June 2007, UTC alleges that he left with a number of documents that UTC contends contain trade secrets chronicling its drug development efforts. Some eight years later Roscigno joined a competitor, Liquidia Technologies, Inc. (Liquidia), to lead that company in its development of an inhaled treprostinil treatment for PAH. UTC alleges that Roscigno used its trade secrets while employed by Liquidia, giving Liquidia an impermissible head start in its drug development efforts. Liquidia now moves for summary judgment arguing, among other things, that the documents at

issue do not contain trade secrets. (Liquidia Technologies, Inc’s Motion for Summary Judgment [Motion], (ECF No. 284).)

2. Having considered the Motion, the related briefing, the arguments of counsel at a hearing on the Motion, and other appropriate matters of record, the Court concludes that the Motion should be DENIED.

I. FACTUAL BACKGROUND

3. The Court does not make findings of fact when ruling on a motion for summary judgment. Instead, the Court summarizes below the material facts it considers to be uncontested and those facts on which a material dispute forecloses summary adjudication. See, e.g., Vizant Techs., LLC. v. YRC Worldwide, Inc., 373 N.C. 549, 551 (2020); Ehmann v. Medflow, Inc., 2017 NCBC LEXIS 88, at *6 (N.C. Super. Ct. Sept. 26, 2017).

Roscigno’s Employment with UTC 4. Plaintiffs UTC and Lung Biotechnology PBC (collectively UTC) and Defendant Liquidia are competitors in the development of treatments for PAH, a rare disease involving abnormally high blood pressure in the lungs. Elevated pressure strains the right side of the heart as it pumps blood to the lungs and ultimately could lead to heart failure. (See Vallerie V. McLaughlin, et al., Addition of Inhaled Treprostinil to Oral Therapy for Pulmonary Arterial Hypertension, 55 J. AM. COLL. CARDIOLOGY (2010), ECF No. 285.1; UTC Annual Report (Form 10-K), ECF No. 256.3.) While there is no cure for PAH, the U.S. Food and Drug Administration (FDA) has approved several drugs for its treatment. (See, e.g., Flolan Prescribing Info., ECF No. 285.2; Ventavis Prescribing Info., ECF No. 285.3.)

5. Roscigno was employed by UTC from 1997 to 2007. 2 (Def. Robert Roscigno’s Aff. Supp. Mot. Summ. J. [Roscigno Aff.] ¶ 3, ECF No. 212.6 (under seal), ECF No. 376 (public version).) At the start of his employment, Roscigno was involved in the clinical development of Remodulin®, a PAH treatment with the active ingredient treprostinil. (Excerpts of Sept. 20, 2023 Dep. of Robert Roscigno [Pls.’ Roscigno Dep.] 283:2−8, ECF No. 303.7 (under seal), ECF No. 366.7 (public version).) UTC first received FDA approval for subcutaneous administration of Remodulin® in 2002, followed by approval for intravenous administration in 2004. (Remodulin®

(Pls.’ Roscigno Dep. 22:18−23:1; Second Am. Compl. ¶ 14, ECF No. 154 (under seal), ECF No. 155 (public version).)

Prescribing Info. (2002), ECF No. 285.10; Remodulin® Prescribing Info. (2004), ECF No. 285.11.)

6. After successfully obtaining FDA approval for Remodulin®, UTC sought to develop an inhaled treprostinil treatment for PAH. It tasked Roscigno with overseeing this work. (Pls.’ Roscigno Dep. 23:2−24:1.) Roscigno designed protocols, collaborated with pharmacokinetic consultants, participated in meetings with regulators, and oversaw the program budget. (Pls.’ Roscigno Dep. 25:1−27:17; see also Aff. and Expert Report of David W. Feigal [Feigal Report] ¶ 87, ECF No. 255.17 (under seal), ECF No. 335.17 (public version).) 3 7. UTC ultimately succeeded in its efforts. In 2009, it received FDA approval for Tyvaso®, an inhaled treprostinil treatment delivered through a nebulizer. (Tyvaso® Prescribing Info., ECF No. 285.12.)

Roscigno’s Resignation and Subsequent Employment with Liquidia 8. Roscigno resigned from UTC on 18 June 2007. (Roscigno Aff. ¶ 8.) At the time of his resignation, Tyvaso® had not yet received FDA approval. (See Feigal Report ¶ 79 (observing that Tyvaso® was not approved as an orphan drug until 9 April 2009).) 4

3 On 9 September 2024, Liquidia filed a Motion to Exclude the opinions of UTC’s expert, Dr. David W. Feigal (Feigal), both at summary judgment and at trial, (ECF No. 312). On 23 July 2025, the Court entered an Order granting in part the Motion and excluding certain of Feigal’s opinions. (See Order on Mot. Exclude, ECF No. 382.) While the Court cites to Feigal’s expert report throughout this Opinion, it does not rely on any excluded statements or opinions.

Despite a practice of conducting exit interviews with departing employees, UTC has no record of an exit interview with Roscigno during which it would have requested the return of any UTC-related information. (Dep. of Alyssa Friedrich, Individually and as Corporate Representative on Behalf of UTC [Pls.’ Friedrich Dep.] 90:8−101:22, ECF No. 255.1 (under seal), ECF No. 335.1 (public version); Dep. of Alyssa Friedrich, Individually and as Corporate Representative on Behalf of UTC [Def.’s Friedrich Dep.] 135:5−136:15, ECF No. 285.17 (under seal), ECF No. 347 (public version); Memo. from A. Friedrich, ECF No. 285.18 (under seal), ECF No. 348 (public version).) Roscigno testified that there was no exit interview. (Roscigno Aff. ¶ 8.)
