Bloom Nu LLC v. ThermoLife International: One-Day Infringement Action
Bloom Nu LLC filed a patent infringement complaint against ThermoLife International LLC in the Central District of California, asserting US8455531B2 against ThermoLife’s Greens & Superfoods and pre-workout supplement products. The case was voluntarily dismissed in its entirety just one day after filing — a timeline that raises questions about the underlying litigation strategy.
A one-day supplement patent filing: strategic probe or procedural misstep?
On 27 June 2024, Bloom Nu LLC filed Case No. 2:24-cv-05442 in the U.S. District Court for the Central District of California, asserting patent infringement of US8455531B2 against ThermoLife International LLC. The accused products include ThermoLife’s Greens & Superfoods, Greens Stick Packs, Original Pre-Workout, and High Energy PreWorkout lines — all consumer dietary supplement products. Bloom Nu was represented by Norton Rose Fulbright LLP, a firm with deep IP litigation capability, suggesting the complaint was not filed casually.
The action was voluntarily dismissed by Bloom Nu in its entirety on 28 June 2024 — just one day after the complaint was filed. The dismissal covered not only the primary infringement claim but also any counterclaims, cross-claims, and third-party claims. The basis of termination is recorded as voluntary dismissal, but the public docket does not specify whether the dismissal was with or without prejudice, leaving open the question of whether Bloom Nu retains the right to refile on the same patent and same accused products.
A one-day litigation arc is highly unusual even for cases resolved by immediate settlement or licensing agreement. Possible explanations include a pre-filing licence agreement reached after the complaint was drafted, a strategic withdrawal upon learning of a defect in the claim, or a filing made to establish a priority date in parallel proceedings. The absence of any defendant counsel on record and the completeness of the dismissal language — covering all claim types — suggests either a clean settlement or a deliberate reset, though the public record does not confirm either interpretation.

Voluntarily dismissed: what the one-day exit means for both parties
Voluntary dismissal: the plaintiff pulls the case entirely
A voluntary dismissal under Federal Rules of Civil Procedure Rule 41 allows a plaintiff to withdraw its action, typically before the defendant has served an answer or motion for summary judgment. Here, Bloom Nu dismissed all claims — primary, counterclaims, cross-claims, and third-party — in a single order. Crucially, the public record does not specify ‘with prejudice’ or ‘without prejudice’, which carries significant legal consequences for whether the action can be refiled.
Rule 41 voluntary dismissalThe public record is silent on prejudice — and that matters
A dismissal ‘without prejudice’ preserves Bloom Nu’s right to refile the same infringement claim against ThermoLife on US8455531B2. A dismissal ‘with prejudice’ would bar any future action on those claims. Under Rule 41(a)(1)(B), a voluntary dismissal is without prejudice unless the notice states otherwise — but practitioners should verify the actual filing rather than rely on default assumptions. The distinction is commercially material for ThermoLife and any third party monitoring this patent.
Refiling risk unresolvedThermoLife exits with no judgment — but not necessarily clear
ThermoLife was dismissed from the case without any merits ruling, meaning no finding of infringement or non-infringement was made regarding its Greens & Superfoods or pre-workout products. No defendant counsel ever appeared on record. While ThermoLife avoids any immediate liability, it faces residual uncertainty: if the dismissal was without prejudice, Bloom Nu may refile. The absence of a declaratory judgment of non-infringement leaves ThermoLife’s freedom-to-operate position on US8455531B2 legally unresolved.
No merits ruling for defendantSports nutrition IP holders should monitor US8455531B2 closely
The rapid dismissal without resolution suggests this patent remains active and potentially in play. Companies operating in the greens, superfoods, and pre-workout supplement categories who compete with ThermoLife’s accused product lines face the same potential infringement exposure. The one-day lifecycle of this case provides no claim construction guidance or invalidity record, meaning the patent’s scope is entirely untested. Competitors should treat US8455531B2 as a live enforcement risk until its status is clarified.

Official order — verbatim text
The dismissal order covers an unusually comprehensive set of claim types — primary action, counterclaims, cross-claims, and third-party claims — suggesting the parties or Bloom Nu alone moved to ensure a complete procedural exit. The language ‘dismissed by the Plaintiff(s) in its entirety’ is consistent with a plaintiff-initiated unilateral withdrawal rather than a stipulated dismissal, though no merits determination was reached. The absence of any prejudice specification in the publicly recorded basis is the most commercially consequential ambiguity in this record.
US8455531B2 — dietary supplement formulation patent
US8455531B2 was filed under application number US13/038537 and covers dietary supplement formulation technology. The patent was asserted in the context of ThermoLife’s greens, superfoods, and pre-workout product lines, suggesting its claims relate to ingredient compositions or formulation methods relevant to botanical, adaptogenic, or performance nutrition categories. The patent’s grant number places its prosecution in a period of significant growth in functional food and supplement IP activity.
For the sports nutrition and dietary supplement sector, US8455531B2 represents an untested enforcement asset: no court has construed its claims or assessed its validity in adversarial proceedings. This makes it potentially high-risk for formulators active in the greens and pre-workout categories. The combination of a sophisticated plaintiff law firm, a one-day voluntary dismissal, and a broad accused product set suggests the patent holder may be pursuing a structured licensing campaign rather than a single dispute resolution.
Should you run an FTO analysis against US8455531B2?
Any company formulating or selling greens blends, superfoods, or stimulant-based pre-workout products in the U.S. market should treat US8455531B2 as a live enforcement risk. The Bloom Nu v. ThermoLife case produced no claim construction or invalidity finding, meaning the patent’s scope has never been judicially tested. If your product line overlaps with ThermoLife’s accused categories — greens powders, stick-pack formats, or high-stimulant pre-workout complexes — a formal FTO analysis is warranted before product launch or expansion.
PatSnap Eureka’s FTO Search Agent can map the independent and dependent claims of US8455531B2 against your specific formulation parameters, identify prior art that could support an invalidity argument, and surface any continuation applications or related family members that may extend the patent’s reach. Given the absence of any litigation history on this patent, Eureka’s claim analysis tools provide the only structured risk signal available to product teams operating in this space.

What this case signals for the dietary supplement IP landscape
A one-day infringement filing by a Norton Rose Fulbright-represented entity is rarely accidental — the supplement sector should take note.
One-day dismissals often precede refiling or licensing — monitor this patent
When well-resourced counsel file and immediately withdraw a patent complaint, it frequently signals that a parallel commercial resolution — licensing, settlement, or strategic repositioning — is underway. Competitors in the greens and pre-workout supplement categories should track US8455531B2 for any continuations, assignments, or fresh enforcement activity.
No merits ruling means ThermoLife’s products carry unresolved IP risk
The voluntary dismissal produced no claim construction, no invalidity finding, and no non-infringement ruling. ThermoLife’s Greens & Superfoods, Greens Stick Packs, and pre-workout products remain legally exposed to the same patent. Any company benchmarking against or competing with those product lines should run a formal FTO analysis against US8455531B2.
Bloom v ThermoLife — key questions answered
Bloom Nu LLC filed a patent infringement action against ThermoLife International LLC on 27 June 2024 in the Central District of California, asserting US8455531B2 against ThermoLife’s Greens & Superfoods, Greens Stick Packs, and pre-workout products. The case was voluntarily dismissed in its entirety by Bloom Nu on 28 June 2024 — one day after filing — with no merits ruling issued.
The public record records the basis of termination as ‘voluntary dismissal’ without specifying with or without prejudice. Under Rule 41(a)(1)(B), a voluntary dismissal is presumptively without prejudice unless the notice states otherwise, which would preserve Bloom Nu’s right to refile. However, practitioners should consult the actual docket filing to confirm the specific terms of dismissal.
The accused products were ThermoLife International LLC’s Greens & Superfoods, Greens Stick Packs, Original Pre-Workout, and High Energy PreWorkout products. No merits ruling was issued, so no finding of infringement or non-infringement was made with respect to any of these products.
US8455531B2 is a U.S. patent asserted by Bloom Nu LLC in the context of greens, superfoods, and pre-workout supplement products, suggesting its claims relate to dietary supplement formulation technology. Because no claim construction or invalidity analysis has been issued in any adversarial proceeding, the patent’s enforceable scope is unresolved — making it a live risk for formulators and brands in these product categories.
A one-day voluntary dismissal most commonly suggests that a commercial resolution — such as a licensing agreement or settlement — was reached after the complaint was filed or that a strategic decision was made to withdraw and refile under different circumstances. It may also reflect a pre-filing agreement that was only executed after the complaint was lodged. The public record in this case does not disclose the specific reason for the rapid dismissal.
