AbbVie v. Teva: Teva Admits Infringement of Elagolix Patents, Accepts Injunction
AbbVie brought a Hatch-Waxman infringement action against Teva in Delaware over two patents covering elagolix sodium co-packaged capsules used to treat heavy menstrual bleeding. Teva admitted both patents are valid, enforceable, and infringed — and was permanently enjoined from commercialising its ANDA 217650 product for the life of either patent. The case resolved in 333 days without a full trial.
Teva’s ANDA admission hands AbbVie a clean elagolix patent win
Filed on 2 February 2023 in the District of Delaware before Judge Richard G. Andrews, this Hatch-Waxman action saw AbbVie assert US Patent Nos. 10,881,659 and 11,045,470 against Teva’s ANDA 217650 — an application for a generic version of elagolix sodium, estradiol, and norethindrone acetate co-packaged capsules, sold under the Oriahnn brand for heavy menstrual bleeding. The filing of an ANDA referencing a listed patent constitutes a technical act of infringement under 35 U.S.C. § 271(e)(2)(A), which triggered AbbVie’s right to sue and a statutory 30-month stay on FDA approval.
The case closed on 2 January 2024 via a consent stipulation and order. Critically, Teva admitted that both the ‘659 and ‘470 patents are valid, enforceable, and would be infringed by the commercial manufacture, use, or sale of its ANDA product. The court then entered a permanent injunction barring Teva — and those acting in concert with it — from commercialising the ANDA 217650 product for the entire remaining life of both patents, including any extensions or pediatric exclusivities, absent an AbbVie licence. Other claims, counterclaims, and defences were dismissed without prejudice.
Resolution in under a year, without trial or claim construction proceedings on the public record, suggests the parties reached an agreed position — possibly including an undisclosed licence or market entry date — before litigation costs escalated. The without-prejudice dismissal of ancillary claims preserves both parties’ positions on any future disputes involving the same patents and a different product. The public record does not disclose whether any licence agreement, settlement payment, or authorised generic arrangement was agreed as part of the broader resolution.

Consent order: Teva admits infringement and accepts permanent injunction
What a consent stipulation and order means
A consent stipulation and order is a binding court judgment agreed by both parties. It carries the same legal force as a litigated judgment. Here, it means Teva’s admission of infringement is on the permanent public record, and the injunction is enforceable by the court for the life of both patents. Both parties also waived any right to appeal or seek relief from its terms.
Binding final judgmentWithout prejudice: what remains open
Ancillary claims, counterclaims, and defences were dismissed without prejudice — meaning Teva retains the right to challenge validity or non-infringement in a future action involving a different product. However, Teva’s explicit admission that the ‘659 and ‘470 patents are valid and enforceable in this action could carry persuasive weight in any future dispute, even if it is not technically preclusive on different product facts.
Future disputes preservedPermanent injunction tied to full patent life
The injunction extends to the life of either patent, including any extensions (e.g., patent term extensions under 35 U.S.C. § 156) and any pediatric exclusivity periods. This means Teva cannot launch its ANDA 217650 product until the last of those protections expires — unless it secures an explicit licence from AbbVie. The injunction binds Teva’s officers, agents, and all persons acting in concert.
Covers extensions & exclusivityWhy ANDA filing itself triggers infringement
Under 35 U.S.C. § 271(e)(2)(A), submitting an ANDA referencing a listed patent is itself a statutory act of infringement, even before any product is manufactured or sold. This Hatch-Waxman mechanism exists to allow brand and generic companies to resolve patent disputes before market entry, giving patent holders like AbbVie the ability to obtain injunctive protection without waiting for actual commercial launch.

Stipulation of dismissal — official text
The consent order is structured as a full final resolution — not a partial settlement. Teva’s admissions on validity, enforceability, and infringement are unqualified and on the public record, which is unusual in Hatch-Waxman litigation where defendants typically preserve invalidity arguments. The permanent injunction covering extensions and pediatric exclusivities closes off near-term generic entry via this ANDA. However, the without-prejudice language on ancillary claims, and the carve-out for future actions on different products, means the parties have deliberately preserved tactical flexibility beyond this specific dispute.
US11045470 & US10881659 — Elagolix sodium co-pack formulations
US10,881,659 (application no. US14/211096) and US11,045,470 (application no. US16/355359) both protect aspects of AbbVie’s elagolix sodium franchise — specifically the co-packaged formulation combining elagolix sodium (eq. 300 mg base), estradiol (1 mg), and norethindrone acetate (0.5 mg) capsules used in the treatment of heavy menstrual bleeding associated with uterine fibroids. The application lineage of the ‘659 patent predates the ‘470 patent, with the ‘470 patent’s application number suggesting a continuation or related filing strategy to extend and refine the protected claim scope across the product lifecycle.
Elagolix (sold as Oriahnn by AbbVie) is a GnRH receptor antagonist, and the co-packaged formulation with add-back hormone therapy represents a clinically and commercially distinctive product design. The dual-patent assertion strategy — asserting two related patents simultaneously against a single ANDA — is consistent with AbbVie’s broader approach to building layered patent protection around its key franchises. For competitors developing GnRH antagonist products or seeking to file ANDAs in women’s health, this outcome demonstrates that AbbVie is prepared to enforce both formulation and method patents aggressively and secure injunctions that cover the full statutory protection period.
Should you run an FTO analysis against US10881659 and US11045470?
Any company developing GnRH antagonist formulations, elagolix sodium combination products, or ANDA applications targeting heavy menstrual bleeding indications should treat these two patents as live blocking risks. The consent order confirms they are valid, enforceable, and actively asserted. R&D and regulatory teams considering formulations involving elagolix sodium — whether in co-pack or standalone configurations — need claim-level FTO analysis before committing to development or ANDA filing costs.
PatSnap Eureka’s FTO Search Agent lets you map claims across US10881659 and US11045470 against your specific product design, identifying freedom corridors or design-around opportunities before litigation risk materialises. Eureka’s claim monitoring tools can also alert your team if AbbVie files continuation applications that extend claim coverage beyond the two patents already asserted — a common lifecycle management strategy in pharmaceutical IP.

What this case signals for the women’s health and ANDA litigation landscape
A swift admission and permanent injunction in a Hatch-Waxman case carries outsized signals for how AbbVie enforces its elagolix franchise.
AbbVie’s elagolix patent position proved strong enough to secure admission
Teva’s unconditional admission that both patents are valid, enforceable, and infringed — without any invalidity counterclaim surviving — suggests AbbVie’s patent portfolio around elagolix sodium formulations is robust. Companies considering ANDA challenges to Oriahnn-related patents should expect aggressive enforcement and well-prepared claim sets.
Early resolution in ANDA cases often signals an undisclosed licence
Consent orders in Hatch-Waxman litigation that arrive within 12 months, without public invalidity arguments, are frequently accompanied by authorised generic agreements or future market-entry licences. The public record here is silent on any such arrangement, but this pattern is well-established in the sector. Monitoring future FDA Orange Book listings and authorised generic designations for ANDA 217650 may reveal undisclosed terms.
AbbVie v Teva — key questions answered
Teva admitted that US10,881,659 and US11,045,470 are valid, enforceable, and would be infringed by the commercial manufacture, use, or sale of the generic elagolix sodium co-packaged product described in ANDA 217650. Teva also admitted the ANDA filing itself was an act of infringement under 35 U.S.C. § 271(e)(2)(A). These admissions are recorded in the court’s consent stipulation and order dated January 2024.
ANDA 217650 is Teva’s Abbreviated New Drug Application to the FDA for a generic version of elagolix sodium (eq. 300 mg base), estradiol (1 mg), norethindrone acetate (0.5 mg) co-packaged capsules — the generic equivalent of AbbVie’s Oriahnn, which is indicated for heavy menstrual bleeding associated with uterine fibroids. The filing of this ANDA triggered AbbVie’s Hatch-Waxman infringement action.
The court’s consent order permanently enjoins Teva, its officers, agents, and all persons acting in concert from manufacturing, using, offering to sell, or selling the ANDA 217650 product in the United States, or importing it, for the entire remaining life of either US10,881,659 or US11,045,470 — including any patent term extensions and pediatric exclusivity periods — unless Teva obtains a licence or authorisation from AbbVie.
The consent order dismissed all other claims, counterclaims, and defences without prejudice as part of the agreed resolution. This means neither party is barred from raising those arguments in a future action. Critically, the order expressly states it does not prejudice any claim or defence in a future action involving either patent and a product other than the ANDA 217650 product, preserving both parties’ flexibility for future disputes.
AbbVie asserted two patents: US10,881,659 (the ‘659 Patent) and US11,045,470 (the ‘470 Patent). Both relate to the elagolix sodium co-packaged formulation used in Oriahnn, a treatment for heavy menstrual bleeding. Both patents were confirmed as valid, enforceable, and infringed by the ANDA 217650 product under the terms of the parties’ consent stipulation.
