Spanx v. Honeylove Sculptwear: Six-Patent Shapewear Dispute Dismissed With Prejudice
Spanx, LLC sued rival shapewear brand Honeylove Sculptwear, Inc. in the Central District of California, asserting six patents — utility and design — across 24 competing garment lines. After 233 days, both parties stipulated to dismiss all infringement claims with prejudice, each absorbing its own legal costs.
Spanx asserts shapewear patent portfolio against direct competitor Honeylove
On 30 December 2024, Spanx, LLC filed a patent infringement action against Honeylove Sculptwear, Inc. in the United States District Court for the Central District of California (Case No. 2:24-cv-11222). Spanx asserted six patents — comprising both utility patents and design patents — against 24 Honeylove products ranging from bodysuits and briefs to shorts and thongs in the shapewear category.
The case closed on 20 August 2025 when the parties filed a stipulated dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). All infringement claims brought by Spanx were dismissed with prejudice, meaning Spanx is permanently barred from re-asserting the same claims against Honeylove based on the same conduct. Critically, each party agreed to bear its own costs, expenses, and attorneys’ fees — a mutual walk-away structure that neither party publicly characterised as a settlement.
The 233-day duration, from filing on 30 December 2024 to close on 20 August 2025, is relatively compressed for a dispute of this complexity. The with-prejudice dismissal absent any fee award suggests the parties likely reached a private commercial arrangement, though the public record is silent on any licensing terms, design changes, or ongoing business relationship. The mutual cost-bearing structure is consistent with a negotiated resolution rather than a litigated outcome on the merits.

Dismissed with prejudice: what the stipulated exit means for both brands
Rule 41 stipulated dismissal with prejudice explained
Under FRCP 41(a)(1)(A)(ii), parties may jointly stipulate to dismiss an action without a court order. A ‘with prejudice’ designation is the critical qualifier here: it operates as a final adjudication on the merits, permanently extinguishing Spanx’s right to re-file the same infringement claims against Honeylove for the same conduct. This is a stronger exit than a voluntary dismissal without prejudice, which would preserve Spanx’s right to refile.
Permanent bar on re-filingSpanx surrenders right to re-litigate these specific claims
By agreeing to a with-prejudice dismissal, Spanx permanently forecloses the option to revive these particular infringement claims against Honeylove on the same factual basis. This is a meaningful concession by the patent holder. However, Spanx retains the ability to enforce these six patents against other parties, and could potentially bring new claims if Honeylove launches materially different products — though such a strategy would carry significant risk.
Patents remain enforceable vs. third partiesHoneylove gains permanent protection from these specific claims
For Honeylove, the with-prejudice dismissal provides lasting legal certainty: Spanx cannot resurrect these six patents against the 24 accused products on the same theory. Represented by WilmerHale, Honeylove avoided a public merits ruling that could have validated Spanx’s IP assertions. The mutual cost-bearing structure suggests neither party was positioned to dominate on the merits, which is commercially significant for a growing direct competitor.
Certainty on accused product linesShapewear IP enforcement: design and utility patents used together
This case is notable for deploying both design patents and utility patents simultaneously against a competitor’s full product range — a portfolio enforcement strategy increasingly common in apparel IP. The swift resolution without a merits ruling leaves the validity and scope of Spanx’s patents untested in court, meaning they remain formidable tools against other competitors. The fashion and shapewear sector should note that design patent portfolios paired with utility claims raise both the cost and complexity of defence.

Official order — verbatim text
The stipulation’s explicit ‘WITH PREJUDICE’ language, capitalised in the original filing, signals a deliberate and final disposition. Under FRCP 41, this operates as a judgment on the merits for res judicata purposes, permanently foreclosing these specific claims. The mutual cost-bearing clause — common in negotiated resolutions — distinguishes this from a plaintiff capitulation and is more consistent with a confidential commercial settlement. No court-ordered relief, damages, or injunction appears on the public record.
US10455866B2 — Shapewear garment utility patent (and 5 further patents)
The six asserted patents span both utility and design protection across Spanx’s shapewear innovations. The utility patents — US10455866B2, US9930916B2, and US9179713B2 — cover functional garment construction technologies in the sculpting and shaping apparel space, including structural and material innovations. The three design patents — USD796784S, USD707920S, and USD796780S — protect the ornamental appearance of specific garment configurations. Together they represent a layered IP strategy covering both how the garments work and how they look.
For the shapewear sector, a portfolio combining utility and design patent protection creates significant competitive moats. Utility patents can block functional imitation even where aesthetics differ, while design patents protect the visual identity of best-selling SKUs. Spanx’s assertion of all six patents across 24 Honeylove product lines suggests the portfolio was specifically constructed to cover the core commercial range of sculpting apparel — briefs, bodysuits, shorts, and thongs — making freedom-to-operate analysis essential for any brand in this space.
Should you run an FTO against Spanx’s shapewear patent portfolio?
Any company developing or commercialising shapewear garments — particularly bodysuits, mid-thigh shorts, briefs, or sculpting camisoles — should treat Spanx’s six-patent portfolio as a live enforcement risk. This case demonstrates that Spanx is willing to assert both utility and design patents simultaneously across an entire product range of a direct competitor. The with-prejudice resolution leaves all six patents valid and unconstrued, meaning their full potential claim scope is intact against third parties.

What this case signals for the shapewear and apparel IP landscape
Spanx’s multi-patent enforcement posture and the swift with-prejudice exit carry clear signals for competing brands and IP counsel in the apparel sector.
Portfolio enforcement: design + utility patents raise the litigation stakes
Spanx asserted three design patents alongside three utility patents — a stacking strategy that forces defendants to defend on both aesthetic and functional grounds simultaneously. For shapewear brands developing competing garments, this dual exposure significantly increases the cost and complexity of any infringement defence. Companies should audit their product lines against both patent types before launch.
With-prejudice exits without fee awards suggest negotiated resolution
The mutual cost-bearing, with-prejudice structure is consistent with a private commercial arrangement — potentially a licence, cross-licence, or product modification agreement — though the public record is silent. When both parties walk away absorbing their own fees after 233 days, a negotiated business outcome is the most plausible explanation, even absent any public confirmation.
Spanx v Honeylove — key questions answered
Spanx filed suit against Honeylove Sculptwear in the Central District of California on 30 December 2024, asserting six patents across 24 shapewear products. The case closed on 20 August 2025 when both parties stipulated to dismissal of all infringement claims with prejudice under FRCP 41(a)(1)(A)(ii). Each party bore its own costs and attorneys’ fees.
A dismissal with prejudice operates as a final adjudication on the merits for res judicata purposes. Spanx is permanently barred from re-filing the same infringement claims against Honeylove based on the same conduct and the same patents. However, Spanx’s six patents remain valid and enforceable against other parties.
Spanx asserted six patents: utility patents US10455866B2, US9930916B2, and US9179713B2, covering shapewear garment construction technologies, and design patents USD796784S, USD707920S, and USD796780S, protecting the ornamental appearance of specific garment configurations. All six patents remain in force post-dismissal.
The public record does not disclose the reason. However, a with-prejudice dismissal with mutual cost-bearing — reached after 233 days — is commonly consistent with a confidential commercial resolution such as a licence, cross-licence, or agreed product modification. Neither party confirmed any settlement terms, so the private commercial substance, if any, remains unknown.
No. Because the case resolved without any merits ruling, none of the six asserted patents were construed, invalidated, or found to infringe in a judicial decision. Their claim scope and validity are legally unchanged. Competing shapewear brands and potential IPR petitioners face no prior judicial construction to rely on — the patents remain in their pre-litigation state.
