Case overview

Swift ANDA enforcement: ARI secures injunction over selenium IV patents

American Regent, Inc. (ARI), a pharmaceutical company and holder of US11998565B2 and US12150957B2, filed suit against BPI Labs, LLC on 16 May 2025 in the District of New Jersey. The dispute centred on BPI’s Abbreviated New Drug Application No. 220051, which covered selenious acid injectable products — parenteral selenium supplements supplied in three concentration configurations — that ARI alleged would infringe its two licensed patents upon approval and commercialisation.

The case terminated on 5 August 2025 via a consent judgment stipulated by both parties. Under the order, BPI and its affiliates, successors, and assigns are enjoined from making, selling, offering to sell, importing, or distributing the BPI ANDA products in the United States without ARI authorisation. All claims and counterclaims were dismissed without prejudice, and no costs or attorneys’ fees were assessed. Critically, the FDA retains the right to grant final ANDA approval, and BPI may maintain Paragraph IV certifications — suggesting a negotiated commercial path may exist under a separate settlement agreement.

Eighty-one days from filing to consent judgment is notably rapid for Hatch-Waxman patent litigation, where cases routinely extend years. The speed is consistent with an early negotiated resolution, likely driven by the 30-month statutory stay mechanism and commercial considerations on both sides. The settlement agreement referenced in the consent judgment is not part of the public record, leaving the precise licensing terms, any authorised generic arrangements, and BPI’s future market entry date undisclosed.

Dismissal terms

Consent judgment with injunction: what the resolution means for both parties

Legal mechanism

Consent judgment enjoins BPI — not a merits ruling

A consent judgment is a court-entered order agreed to by both parties, carrying the full enforcement weight of a judicial decree without a trial on the merits. Here, BPI stipulated to an injunction covering both ARI patents, meaning any future violation is directly actionable as contempt. The dismissal of all claims without prejudice preserves each party’s ability to relitigate if the settlement agreement is breached, but does not constitute an admission of liability by either side.

Enforceable by court order
Dismissal with/without prejudice

Claims dismissed without prejudice — rights preserved

The order expressly dismisses all claims, counterclaims, affirmative defenses, and demands without prejudice. This means BPI has not surrendered its right to challenge patent validity or non-infringement in a future proceeding if circumstances change — for example, if the settlement agreement’s terms are disputed. Without prejudice dismissal in this context is standard in Hatch-Waxman consent judgments and does not indicate weakness in ARI’s patent position; it reflects mutual risk management.

Without prejudice
Patent holder outcome

ARI secures injunction and protects selenious acid market position

American Regent obtained a court-enforced injunction blocking BPI’s ANDA product from the US market absent ARI authorisation. The consent judgment binds BPI’s affiliates, successors, and assigns — structurally limiting workarounds via corporate restructuring. ARI’s two selenium IV patents are effectively shielded from near-term generic competition, and the referenced settlement agreement likely defines a controlled entry date or licensing royalty that ARI negotiated from a position of strength.

Injunction granted
Generic challenger outcome

BPI retains ANDA and Paragraph IV rights — future entry possible

BPI accepted the injunction but preserved material optionality: the FDA may still grant final ANDA approval, and BPI may continue filing or maintaining Paragraph IV certifications. This structure is consistent with an authorised generic agreement or a defined market entry date embedded in the undisclosed settlement. BPI avoided a costly trial while keeping its ANDA alive — suggesting the commercial calculus favoured a negotiated entry path over full patent challenge.

Official order — verbatim text

“American Regent, Inc. ("ARI") and BPI Labs, LLC ("BPI"), parties in the above-captioned action, specifically in the action initiated by Plaintiff, ARI, against BPI in Civil Action No. 25-cv-04439, have resolved this litigation for good cause and valuable consideration recognized by ARI and BPI. Now the parties, by their respective undersigned attorneys, hereby stipulate and consent to entry of judgment and an injunction in the action, as follows: IT IS this 5th day of August, 2025: ORDERED, ADJUDGED AND DECREED as follows: 1. This District Court has jurisdiction over the subject matter of the above action and has personal jurisdiction over the parties. 2. As used in this Consent Judgment, (i) the term "BPI Product(s)" shall mean the drug product(s) manufactured, sold, offered for sale or distributed pursuant to Abbreviated New Drug Application No. 220051 (including any supplements, or modification or amendments thereto or replacements thereof) ("BPI’s ANDA"); (ii) the term "Licensed ARI Patents" shall mean United States Patent Nos. 11,998,565 ("the ‘565 patent") and 12,150,957 ("the ‘957 patent"); and (iii) the term "Affiliate" shall mean any entity or person that, directly or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with BPI; for purposes of this definition, "control" means: (a) ownership, directly or through one or more intermediaries, of: (1) more than fifty percent (50%) of the shares of stock entitled to vote for the election of directors, in the case of a corporation, or (2) more than fifty percent (50%) of the equity interests in the case of any other type of legal entity or status as a general partner in any partnership; or (b) any other arrangement whereby an entity or person has the right to elect a majority of the Board of Directors or equivalent governing body of a corporation or other entity or the right to direct the management and policies of a corporation or other entity. Unless otherwise specifically authorized by ARI pursuant to the Settlement Agreement or by 35 U.S.C. § 271(e)(1), BPI, including any of its Affiliates, successors and assigns, is enjoined from infringing the Licensed ARI Patents, on its own part or through any Affiliate, by making, having made, using, selling, offering to sell, importing or distributing of the BPI Product(s) in the United States. . Compliance with this Consent Judgment may be enforced by ARI, its successors in interest, or assigns, as permitted by the terms of the Settlement Agreement. This District Court retains jurisdiction to enforce or supervise performance under this Consent Judgment and the Settlement Agreement. All claims, counterclaims, affirmative defenses and demands in this action are hereby dismissed without prejudice and without costs, disbursements or attorneys’ fees to any party.Nothing herein shall preclude the U.S. Food & Drug Administration from granting final approval to BPI’s ANDA or shall preclude BPI from filing, modifying, or maintaining with the FDA any Paragraph IV Certification for the BPI Product(s) pursuant to 21 U.S.C. § 355(j)(2)(A)(vii)(IV).”
Source: PACER Docket, Case 2:25-cv-04439, New Jersey District Court

The consent judgment is a stipulated court order, not a merits determination — the court made no finding on infringement or validity. Its enforcement significance lies in the injunction’s breadth: BPI and all affiliated and successor entities are barred from commercialising ANDA No. 220051 products absent ARI authorisation. The without-prejudice dismissal preserves litigation rights but practically these are constrained by the parallel private settlement agreement, whose breach triggers the court’s retained jurisdiction. The FDA approval and Paragraph IV carve-outs are the operative signals that a negotiated market-entry arrangement likely exists outside the public record.

US11998565B2 and US12150957B2 both cover selenious acid injectable formulations used to deliver selenium intravenously in parenteral nutrition settings. The application numbers (US18/124391 and US18/672876 respectively) suggest relatively recent filings, consistent with lifecycle management or reformulation patents protecting ARI’s established selenium IV product line. Selenium is an essential micronutrient supplied via injection in critically ill or long-term parenterally fed patients, making this a specialist but clinically critical pharmaceutical category.

In the context of ANDA litigation, these patents sit on the Orange Book and trigger the Hatch-Waxman 30-month stay upon a Paragraph IV challenge — a powerful commercial lever for the innovator. ARI’s ability to obtain a consent injunction against both patents within 81 days suggests a robust claim scope that BPI found difficult to design around or invalidate quickly. Any pharmaceutical company developing a generic selenious acid IV product, or seeking to acquire BPI’s ANDA, faces direct infringement exposure under both assets until their expiry or a negotiated licence.

Freedom to operate

Should you run an FTO against US11998565B2 and US12150957B2?

Pharmaceutical manufacturers, compounding pharmacies, and generic drug developers working with parenteral selenium formulations — particularly selenious acid injectables at any concentration — should treat both ARI patents as live enforcement risks. The consent judgment confirms ARI’s willingness to litigate rapidly and pursue injunctive relief. The binding of affiliates and successors in the consent order also means ANDA acquirers and licensing partners carry inherited exposure if they step outside the settlement’s boundaries.

PatSnap Eureka’s FTO Search Agent can map the claim scope of US11998565B2 and US12150957B2 against your formulation specifications, identify any design-around opportunities, and surface related continuation or family applications that may extend ARI’s exclusivity window. Running a structured FTO now — before ANDA filing or product launch — is materially lower cost than defending a consent-judgment-backed enforcement action in the District of New Jersey.

Strategic implications

What this case signals for the parenteral nutrition IP landscape

Swift consent judgments in ANDA cases signal patent strength and early leverage — here is what competitors and IP teams should note.

Early consent judgments typically reflect strong patent positions

When an ANDA filer agrees to a consent injunction within 81 days of suit — before claim construction or any substantive motion — it typically suggests the patent holder presented credible infringement evidence and the generic filer assessed litigation risk as unfavourable. IP teams monitoring the selenious acid space should treat both ARI patents as high-enforcement-probability assets.

The undisclosed settlement agreement is where the real commercial terms live

The public consent judgment reveals the injunction but not the deal. The retained FDA approval pathway and preserved Paragraph IV certifications for BPI strongly suggest a licence or authorised generic arrangement is embedded in the private settlement. Competitors evaluating market entry should monitor FDA Orange Book patent listings and ANDA approval dates for indirect signals about agreed entry windows.
