Evolution Nutraceuticals Incorporated v. ThermoLife International LLC — Court Stays Non-Markman Discovery Pending Claim Construction

Background

Plaintiff Evolution Nutraceuticals Incorporated and Defendant ThermoLife International LLC filed a Joint Discovery Dispute on October 30, 2026 (Doc. 116), disagreeing over whether discovery should be stayed pending the Court's claim construction order. Defendant requested a stay of discovery until the Court issues its claim construction order, arguing that the order will streamline the case, while Plaintiff opposed any stay, claiming that halting discovery would prejudice its ability to present its positions at the claim construction hearing. The Court observed that the parties' contentions were brief and lacking in detail, yet it was inclined to stay all discovery not directly related to the claim construction hearing.

The underlying action concerns the '531 Patent. Plaintiff's remaining claims are declaratory judgment of noninfringement of the '531 Patent, declaratory judgment of invalidity of the '531 Patent, tortious interference, and bad faith infringement under the Arizona Patent Troll Prevention Act. On February 13, 2026, the Court dismissed Plaintiff's Arizona Consumer Fraud Act claim with prejudice and its trade libel and Lanham Act claims without prejudice, and the Court corrected Plaintiff's inaccurate assertion that those dismissed claims were still pending, noting that counsel is expected to be up-to-speed on what has already transpired.

The parties had already conducted significant discovery following Plaintiff's initial Motion for Preliminary Injunction, enough that both sides were fully able to argue likelihood of success on the merits as to noninfringement and invalidity in the renewed preliminary injunction briefing. The Court's Rule 16 Scheduling Order is focused solely on the claim construction hearing, with the parties to propose remaining deadlines only after the claim construction order issues.

The Court’s Holding

The Court found a limited stay of discovery warranted to promote judicial economy and preserve the parties' and the Court's resources, citing Landis v. North American Co., 299 U.S. 248, 254 (1936). It ordered that all discovery in the matter unrelated to claim construction and the Markman hearing is stayed until further order of the Court. The Court noted that although the parties represented that Plaintiff served 355 discovery requests and Defendant served 265, neither side stated how many requests remain outstanding or which are relevant to the Markman hearing, leaving the Court unable to resolve what it called an amorphous dispute based only on broad contentions of prejudice and unmeritoriousness.

The Court further ordered the parties to meet and confer within seven days of the Order as to any outstanding discovery crucial to receive in advance of the Markman hearing. To the extent the parties agree on discovery to be provided, it should be promptly supplied; if they cannot agree on what outstanding discovery is necessary, they may file a subsequent notice of discovery dispute detailing the specific discovery sought and any objection to its production. The Court forewarned that it will not appreciate an additional discovery dispute occupying its limited time that is not reflective of considerable, sincere efforts to resolve the points of contention.

Key Takeaways

• District courts may stay discovery pending claim construction when the current Rule 16 scheduling order focuses solely on the Markman hearing and the parties have already conducted substantial discovery on the merits.
• A party opposing a discovery stay must identify with specificity what discovery remains outstanding and why it is essential to the claim construction hearing, rather than relying on broad contentions of prejudice.
• The Court corrected Plaintiff's inaccurate assertion about its pending claims, emphasizing that counsel is expected to be up-to-speed on prior orders dismissing certain claims with or without prejudice.
• Judicial economy and resource preservation under Landis v. North American Co. support limiting discovery to issues directly relevant to upcoming claim construction when the scheduling order is similarly focused.
• Parties must engage in considerable, sincere meet-and-confer efforts within the court-ordered window before burdening the court with additional discovery disputes.

Why It Matters

This order illustrates the practical application of judicial economy principles to patent case management, authorizing a targeted discovery stay that carves out Markman-related discovery while halting broader merits discovery. By requiring the parties to meet and confer regarding essential claim construction discovery within a strict seven-day window, the Court balanced efficient case progression against the risk of prejudice to the party opposing the stay, and it signaled that vague, undeveloped discovery disputes will not be entertained.

The decision also cautions patent litigators about maintaining accurate records of pending claims and prior orders. The Court's explicit correction of Plaintiff's mischaracterization of the live claims underscores that counsel's familiarity with the procedural history is a baseline expectation, and inaccurate assertions about dismissed claims can undermine credibility in later disputes.
