v. No. 25-1278 (D.C. No. 1:24-CV-02558-RMR-KAS)

MICHAEL THOMPSON, (D. Colo.)

Defendant - Appellant.

ORDER AND JUDGMENT *

Before EID, EBEL, and FEDERICO, Circuit Judges.

After two separate stints as a salesman for Appellee Edwards Lifesciences LLC (“Edwards”), Appellant Michael Thompson twice left to join a competitor. When Thompson left the second time, to sell a product that competed with one he had previously sold for Edwards, Edwards brought suit in the District of Colorado to enforce its employment contract with Thompson. Edwards alleged Thompson violated the non-competition and non-solicitation provisions of his contract, each of which had eighteen-month effective periods after Thompson left the company.

This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.

Edwards also alleged Thompson violated the non-disclosure provision of his contract, which runs in perpetuity. While the case proceeded in the district court, Edwards sought a preliminary injunction to enforce the contract provisions. The district court granted the preliminary injunction, to expire on the same date that the non- competition and non-solicitation contract provisions expired. Thompson appealed the district court’s order, but while that appeal unfolded, the preliminary injunction ran its course. Because Thompson is no longer constrained by the preliminary injunction, the sole ground for appeal, his appeal is moot.

I. BACKGROUND

Thompson sells cardiac medical devices. Aplt. Br. at 2. Thompson first worked for Edwards from 2012 to 2021. Id. at 5-6. Then, he left for competitor Abbott Laboratories, at which point Edwards raised no concerns because he was selling a non-competing device. Id. at 6. Thompson returned to Edwards from July 2022 to July 15, 2024, when he again left for Abbott, this time to sell a competing device. 1 Id. at 6, 9. In Thompson’s employment contract with Edwards, there were three provisions creating the covenant at issue: 1) an eighteen-month non- competition period in which he could not directly compete with Edwards’ products, 2) an eighteen-month non-solicitation period in which he could not solicit Edwards’ customers that he had serviced in the previous year, and 3) an indefinite

confidentiality period in which Thompson could not use or disclose Edwards’ confidential information, including: trade secrets; data regarding vendors, customers, sales, and pricing; and information regarding suppliers, competitors, and customers. Dist. Ct. Order at 11.

Edwards sued Thompson for misappropriating trade secrets, under federal and state law, and breaching his contract through his work for Abbott. Id. at 18-19. Edwards sought permanent injunctive relief and compensatory damages based on allegations that Thompson provided customer pricing and preference information to Abbott, accessed Edwards’ confidential product information in the lead up to his departure, and solicited restricted customers. 2 Id. at 15-18. Additionally, while the district court case unfolded, Edwards moved for a preliminary injunction barring Thompson from violating the contract. Id. at 1-2. The district court granted the preliminary injunction on June 18, 2025, to run until January 15, 2026—the day that the eighteen-month effective periods for the non-competition and non-solicitation contract provisions expired. Id. at 39-40. So, the preliminary injunction would ensure that these provisions were enforced throughout the remainder of their duration, but once they expired, neither the contract itself nor the preliminary injunction would bar Thompson from competing with Edwards’ products and soliciting Edwards’ customers. The employment contract would, of course, still prohibit Thompson from disclosing confidential information going forward.

2 Again, the facts relating to Thompson’s violations of the contract provisions, disputed in the proceedings below, are not relevant to the question before us.

Thompson then appealed the grant of a preliminary injunction, arguing the district court erred in three ways: 1) by finding Edwards was substantially likely to succeed on the merits of the non-competition issue, 2) by finding Edwards would suffer irreparable harm, and 3) by granting an unnecessarily broad injunction that barred all sales to Edwards’ customers anywhere in the country. Aplt. Br. at 1. Thompson filed his appeal on July 18, 2025. After submitting his initial brief on September 22, 2025, the last day to do so including a one-week extension, Order Granting Mot. to Extend Time, Thompson filed a motion to expedite his appeal on December 1, 2025. Mot. of Aplt. to Expedite Appeal at 8. Before this court heard his appeal, the preliminary injunction expired. At that point, Edwards moved to dismiss the appeal as moot. Aple. Mot. for Summ. Disposition at 1. Without conceding mootness as to the preliminary injunction, Thompson now shifts focus and urges this court to weigh in on the district court’s interpretation of “trade secrets” for purposes of his ongoing non-disclosure obligation under the employment contract. Resp. of Aplt. to Mot. for Summ. Disp. at 5.

II. ANALYSIS

“Constitutional mootness doctrine is grounded in the Article III requirement that federal courts may only decide actual ongoing cases or controversies.” Seneca– Cayuga Tribe of Okla. v. Nat’l Indian Gaming Comm’n, 327 F.3d 1019, 1028 (10th Cir. 2003) (internal quotation omitted). “If the issues in a case before us are no longer live,” such as when “an event occurs while a case is pending on appeal” that renders the case moot, we must dismiss the case. Prier v. Steed, 456 F.3d 1209, 1212

(10th Cir. 2006) (internal quotations omitted). Generally, appellate courts only have jurisdiction to review “final decisions of the district courts.” 28 U.S.C. § 1291. Though this court may review the grant of a preliminary injunction as an interlocutory order, 28 U.S.C. § 1292, to weigh in on the underlying merits of an ongoing dispute in the district court would be premature.

Thompson asserts that this appeal is still alive because the district court errantly ascribed too broad a scope to “trade secrets” in its preliminary injunction order, considering his “generalized customer information” a trade secret such that he cannot operate as a salesman without using this knowledge. Resp. of Aplt. to Mot. for Summ. Disposition at 15. And he argues that he is still under the effect of the district court’s erroneous interpretation because, while the preliminary injunction itself is no longer in force, he fears the district court will apply the same allegedly errant interpretation of “trade secrets” when it decides the underlying misappropriation and breach of contract dispute. Id. at 5. The problems with Thompson’s argument are two-fold.
