iBeauty Brands v. Bondi Boost: Design Patent Dispute Ends in Voluntary Dismissal
iBeauty Brands, Inc. filed suit against Bondi Boost US, LLC in the Delaware District Court, asserting design patent USD996829S covering an infrared thermal brush. The case was voluntarily dismissed without prejudice after 144 days, leaving the door open for future action.
Design patent clash over infrared thermal brush ends quietly in Delaware
iBeauty Brands, Inc. initiated this infringement action on June 10, 2024, in the Delaware District Court before Judge Jennifer Choe-Groves, asserting design patent USD996829S (application number US29/788594) against hair-care brand Bondi Boost US, LLC. The asserted patent covers the ornamental design of an infrared thermal brush — a product segment that has seen rapid commercial growth as consumers and professionals seek heat-styling tools with infrared technology.
The case ended on November 1, 2024, when the court ordered dismissal pursuant to Plaintiff’s Notice of Voluntary Dismissal Without Prejudice under Federal Rule of Civil Procedure 41(a)(1). The order, issued by Judge Choe-Groves, confirms the case is closed without a merits determination. The public record does not disclose whether a settlement was reached or what, if any, commercial terms accompanied the dismissal.
At 144 days, the case resolved well before any claim construction or substantive motion practice would typically occur in Delaware, suggesting either early-stage negotiations or a strategic reassessment by iBeauty Brands. No defendant law firm appeared on the docket, which may indicate limited formal engagement by Bondi Boost before the dismissal was filed. The absence of a prejudice determination in the underlying notice, as recorded, leaves the precise basis ambiguous in the public record.
Filing to Voluntary dismissal in 144 days
144 days — resolved before any substantive court rulings
Voluntarily dismissed: what Rule 41(a)(1) means for both parties
Rule 41(a)(1): plaintiff withdraws before defendant answers
Federal Rule of Civil Procedure 41(a)(1) allows a plaintiff to dismiss its own action by filing a notice before the defendant serves an answer or motion for summary judgment. The court’s order confirms dismissal under this rule. No defendant agents appear on the docket, consistent with an early-stage withdrawal. Critically, the verdict text specifies dismissal ‘without prejudice’, meaning iBeauty Brands retains the right to refile the same claims.
Procedural dismissal — no merits rulingWithout prejudice confirmed — but public record is limited
The court order expressly states dismissal ‘without prejudice’, meaning the claims are not extinguished and iBeauty Brands may refile. This differs from a dismissal with prejudice, which would bar the same claims permanently. While the verdict text is clear on this point, the record does not disclose whether any side agreement or settlement accompanied the withdrawal, leaving the commercial context of the dismissal unknown.
Refiling rights preserved for plaintiffBondi Boost exits without a finding — but risk persists
Bondi Boost US, LLC faces no adverse judgment and no injunction from this action. No defendant counsel appeared on record, suggesting the company may not have formally engaged before the dismissal was filed. However, the without-prejudice dismissal means iBeauty Brands could refile in Delaware or another jurisdiction, and the underlying design patent USD996829S remains valid and enforceable. Bondi Boost’s exposure to future design patent claims over its infrared thermal brush line is not eliminated.
No judgment — future risk unresolvedDesign patent enforcement in hair-care tools remains a live threat
The voluntary dismissal without prejudice does not signal that iBeauty Brands has abandoned its IP position. In competitive consumer product categories like infrared thermal brushes, design patents are frequently used to protect product aesthetics and market share. Other brands developing or distributing similar styling tools should treat USD996829S as an active enforcement risk and consider conducting freedom-to-operate analysis against the asserted ornamental design.

Official order — verbatim text
The court’s order adopts the plaintiff’s notice verbatim, confirming dismissal under Rule 41(a)(1) without prejudice. This procedural mechanism requires no judicial finding on the merits — the court’s role is limited to acknowledging the withdrawal. The express ‘without prejudice’ language is legally significant: it preserves iBeauty Brands’ right to assert USD996829S in future proceedings, and Bondi Boost receives no res judicata protection from this dismissal.
USD996829S — ornamental design for an infrared thermal brush
USD996829S, filed under application number US29/788594, is a United States design patent protecting the ornamental appearance of an infrared thermal brush. Design patents under 35 U.S.C. § 171 cover the novel, ornamental characteristics of a functional article — in this case, the visual design of a brush that incorporates infrared heat technology for hair styling. The scope of protection is defined by the patent’s drawings, not a written description, making visual similarity the central question in any infringement analysis.
Infrared thermal brushes occupy a growing premium segment of the consumer hair-care market, where brand differentiation is heavily driven by product aesthetics. A design patent on this form factor gives iBeauty Brands a tool to challenge competing products that replicate the protected appearance, regardless of functional differences. For competitors and new entrants developing infrared styling tools, USD996829S represents an active design exclusion risk that warrants close monitoring, particularly given the plaintiff’s demonstrated willingness to file in federal court.
Should your product team run an FTO against USD996829S?
Any brand manufacturing, importing, or distributing infrared thermal brushes in the US market should assess exposure to USD996829S. Design patent infringement turns on whether an ordinary observer, familiar with the prior art, would find the accused product substantially similar in overall visual impression to the patented design. If your brush shares key visual features — handle profile, head geometry, surface detailing — with the patented design, an FTO is warranted before launch or scale.
PatSnap Eureka’s FTO Search Agent enables product and IP teams to map the visual claim scope of USD996829S against your device designs, identify prior art that may narrow enforceability, and surface related design applications in iBeauty Brands’ portfolio. Run an automated FTO analysis to quantify your risk exposure before your next product launch in the infrared styling tool category.

What this case signals for the hair-care device IP landscape
A fast voluntary dismissal in Delaware rarely signals the end of a design patent dispute — it often marks a tactical reset.
Without-prejudice dismissal preserves iBeauty’s enforcement options entirely
USD996829S remains valid and enforceable. iBeauty Brands can refile against Bondi Boost or any other party in any competent jurisdiction. Competitors in the infrared thermal brush space should monitor this patent and any continuation or related design applications closely.
No defendant appearance suggests very early resolution or non-engagement
The absence of any recorded defendant counsel is notable. It may indicate a swift out-of-court resolution, a decision by Bondi Boost not to formally respond, or an agreement that rendered litigation unnecessary. Each scenario carries different implications for how aggressively iBeauty Brands may pursue future enforcement.

A dismissal without prejudice means the claims are not extinguished. iBeauty Brands retains the right to refile the same infringement claims against Bondi Boost or any other party in the future. Design patent USD996829S remains valid and enforceable, and the dismissal does not constitute any finding that the patent is invalid or not infringed.

Under 35 U.S.C. § 171, design patents cover the novel visual characteristics of a functional article. The scope is defined by the patent’s drawings. Any product that an ordinary observer would find substantially similar in overall visual impression may be found to infringe.
The public docket records no defendant agents or law firm for Bondi Boost US, LLC in this case.

The public record does not disclose the commercial terms, if any, behind the dismissal.
No. A voluntary dismissal without prejudice under Rule 41(a)(1) involves no merits determination and creates no legal precedent. The court made no findings on infringement, validity, or claim scope.
