Miller Manufacturing v. Wolltex — Poultry Nesting Box Design Patent Dismissed
Miller Manufacturing Company filed suit against Wolltex, LLC in Minnesota federal court alleging infringement of USD650534S, a design patent covering a poultry nesting box. The case closed after 238 days via voluntary dismissal without prejudice, leaving open the possibility of refiling.
Quick exit in the agricultural equipment design patent space
On May 31, 2023, Miller Manufacturing Company, Inc. filed an infringement action against Wolltex, LLC in the U.S. District Court for the District of Minnesota (Case No. 0:23-cv-01624). The dispute centered on USD650534S (application no. US29/393472), a design patent covering the ornamental appearance of a poultry nesting box — a product category central to small-scale and backyard poultry farming markets. Miller was represented by Taft, Stettinius & Hollister LLP; no defendant counsel appears on the public docket.
The case ended on January 24, 2024, when Miller filed a Notice of Voluntary Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court ordered dismissal without prejudice. Because no answer or motion for summary judgment had been filed by Wolltex — a prerequisite for Rule 41(a)(1)(A)(i) to apply — Miller was entitled to dismiss unilaterally. The without-prejudice designation means Miller retains the legal right to assert the same patent claims against Wolltex in a future action.
At 238 days, the timeline suggests the dispute was resolved or abandoned before substantive litigation commenced. The absence of defendant counsel on the record, combined with the early voluntary dismissal, is consistent with either a private settlement, a licensing arrangement, or a reassessment of litigation strategy by the plaintiff. The public record does not disclose any financial terms or formal agreement, leaving the precise driver of dismissal unknown.
Filing to resolution in 238 days
238 days — resolved faster than most comparable design patent infringement cases
Dismissed without prejudice — what this means for both parties
Rule 41(a)(1)(A)(i) allows unilateral plaintiff exit
Federal Rule of Civil Procedure 41(a)(1)(A)(i) permits a plaintiff to dismiss its own case without a court order, provided the defendant has not yet served an answer or a motion for summary judgment. The absence of any recorded defendant counsel or filings suggests Wolltex had not formally appeared, making Miller’s unilateral notice legally straightforward and immediately effective upon filing.
Plaintiff-initiated exitWithout prejudice preserves Miller’s right to refile
A dismissal without prejudice does not extinguish the underlying claim. Miller Manufacturing retains the ability to refile its infringement action against Wolltex, subject to any applicable statute of limitations. This contrasts sharply with a dismissal with prejudice, which would bar refiling permanently. The public record is silent on whether any settlement or licence agreement was reached — the without-prejudice designation alone does not confirm or deny a private resolution.
Refiling remains possibleNo defendant counsel on record — an unusual signal
The docket lists no counsel or law firm for Wolltex, LLC. While LLCs are required to retain counsel to litigate in federal court, the absence here — combined with an early dismissal — suggests Wolltex may not have formally appeared before the case concluded. This is consistent with scenarios such as a rapid private settlement, a default posture prompting plaintiff reassessment, or an agreed resolution negotiated outside formal litigation channels.
No formal defendant appearanceUSD650534S protects ornamental appearance, not function
Design patents under 35 U.S.C. § 171 protect the ornamental, non-functional appearance of an article of manufacture. USD650534S covers the visual design of a poultry nesting box — meaning infringement turns on whether an ordinary observer would find the accused product substantially similar in appearance to the patented design. Functional elements of a nesting box would not fall within the patent’s scope, a distinction critical to any future litigation or freedom-to-operate analysis.

Stipulation of dismissal — official text
The court’s order adopts the plaintiff’s Notice of Voluntary Dismissal under Rule 41(a)(1)(A)(i) without modification, ordering dismissal without prejudice. The phrasing ‘IT IS HEREBY ORDERED’ is standard procedural confirmation — the court exercised no independent merits judgment. For Miller, the order preserves every claim it asserted. For Wolltex, the case closes without any admission of liability, but the patent remains enforceable and the threat of refiling is real.
USD650534S — Ornamental design patent for a poultry nesting box
USD650534S (application no. US29/393472) is a U.S. design patent protecting the ornamental appearance of a poultry nesting box. Design patents under 35 U.S.C. § 171 cover the visual, non-functional characteristics of a manufactured article. The scope of protection is defined by the drawings filed with the application — any competitor product that an ordinary observer would find substantially similar to those drawings is potentially infringing. The patent sits within the agricultural and animal husbandry equipment domain.
For manufacturers and distributors in the backyard poultry, small-farm, and agricultural supply markets, USD650534S represents a meaningful IP asset held by an established player. Miller Manufacturing’s willingness to enforce this patent in federal court signals that design differentiation in this product category is actively policed. Competitors introducing nesting box designs should conduct an ordinary-observer analysis against the patent’s drawings before launch — aesthetic similarity, not mechanical copying, triggers liability.
Should your team run an FTO against USD650534S?
Any company designing, sourcing, importing, or retailing poultry nesting boxes that bear visual resemblance to Miller Manufacturing’s patented form should treat an FTO assessment as a pre-launch priority. The ordinary observer standard used in design patent infringement is intentionally broad — even unintentional aesthetic similarity can create liability. This is especially relevant for private-label and OEM suppliers operating in the backyard poultry and small-farm equipment categories.
PatSnap Eureka’s FTO Search Agent allows R&D and product teams to map the ornamental claims of USD650534S against their own product designs, identify design-around opportunities, and monitor for new design filings from Miller Manufacturing. Claim monitoring alerts can flag continuations or related design applications in this product category before they become enforcement risks.

What this case signals for the agricultural equipment IP landscape
A swift, uncontested dismissal in a design patent dispute often signals more than a simple walkaway — it warrants scrutiny from competitors and IP teams alike.
Voluntary dismissal without prejudice should not be read as a clean exit
Miller Manufacturing’s right to refile remains intact. Competitors operating in the poultry nesting box or broader small-animal housing market should treat USD650534S as an active enforcement risk. The without-prejudice dismissal preserves all optionality for the patent holder, and a repeat filing — potentially with stronger evidence — cannot be ruled out.
Design patents are potent tools in agricultural equipment markets
The poultry equipment sector, including backyard and small-farm products, is increasingly competitive. Design patents like USD650534S provide a relatively low-cost enforcement mechanism against look-alike products. Companies sourcing or manufacturing similar nesting boxes should conduct design-around analyses before market entry, as ornamental similarity — not functional copying — is the legal standard.
Miller v Wolltex — key questions answered
The case was dismissed without prejudice on January 24, 2024. Plaintiff Miller Manufacturing filed a voluntary notice of dismissal under Rule 41(a)(1)(A)(i). No merits ruling was issued. Miller retains the right to refile infringement claims based on USD650534S against Wolltex.
The patent in dispute is USD650534S (application no. US29/393472), a U.S. design patent covering the ornamental appearance of a poultry nesting box. Design patents protect the visual, non-functional characteristics of a product rather than its mechanical function.
Dismissal without prejudice means Miller Manufacturing’s infringement claims are terminated for this proceeding but are not permanently barred. Miller retains the legal ability to refile the same claims against Wolltex in a future action, subject to the applicable statute of limitations for patent infringement.
Rule 41(a)(1)(A)(i) permits a plaintiff to voluntarily dismiss its case without a court order before the defendant has served an answer or a motion for summary judgment. The public docket lists no defendant counsel or answer for Wolltex, suggesting Wolltex had not formally responded, making the rule available to Miller as a matter of right.
The public record does not disclose any settlement agreement or licensing terms. The without-prejudice dismissal and absence of defendant counsel on the docket are consistent with a private resolution, but also with a plaintiff reassessing litigation strategy. Neither conclusion can be confirmed from available court documents alone.
