Airigan Solutions v. Morning Chef & Yuhuan Aobo: NEGG Egg Peeler Patent Dismissed With Prejudice
Airigan Solutions, LLC asserted US9968211B2 — the patent behind the NEGG® brand egg peeler — against Morning Chef and manufacturer Yuhuan Aobo Plastic Industry Co. in the Western District of Pennsylvania. The case ended in a stipulated dismissal with prejudice after 182 days, with all parties bearing their own costs and fees.
NEGG® egg peeler patent dispute ends in binding stipulated dismissal
Airigan Solutions, LLC filed suit on October 8, 2024 in the Western District of Pennsylvania before Judge William S. Stickman IV, asserting infringement of US9968211B2 — the patent protecting the NEGG® brand boiled egg peeler. The accused products included devices marketed as boiled egg peelers, egg crackers, and egg peelers, sold under the Morning Chef brand and manufactured by Yuhuan Aobo Plastic Industry Co., a Chinese plastics manufacturer.
The case terminated on April 8, 2025 via a Rule 41(a)(1)(A)(ii) stipulated dismissal with prejudice. Both parties signed the stipulation after Yuhuan Aobo had already filed an Answer — meaning the dismissal required mutual consent rather than unilateral plaintiff action. The with-prejudice designation means Airigan Solutions is permanently barred from reasserting the same infringement claims against Yuhuan Aobo on the same patent. Each party bears its own attorneys’ fees and costs, suggesting no prevailing-party determination was made.
Resolution in 182 days is notably swift for a patent infringement matter in the Western District of Pennsylvania, suggesting the parties likely reached a commercial resolution — potentially a licensing arrangement or agreed market exit — without protracted discovery or claim construction proceedings. The public record does not disclose any settlement terms, royalty agreement, or consent injunction, leaving the commercial outcome opaque. The case caption also names Morning Chef as a defendant, though the stipulation on record addresses only Yuhuan Aobo, which may indicate separate or ongoing proceedings with respect to that party.

Dismissed with prejudice: what the stipulated termination means for both parties
Rule 41(a)(1)(A)(ii) requires both parties to sign
Because Yuhuan Aobo had already filed an Answer before dismissal was sought, Airigan Solutions could not unilaterally withdraw under Rule 41(a)(1)(A)(i). The stipulated route under Rule 41(a)(1)(A)(ii) required the defendant’s written consent. That consent, combined with the with-prejudice designation, makes the dismissal a permanent, court-recognised end to these specific claims.
Bilateral consent requiredAirigan Solutions permanently relinquishes these claims against Yuhuan Aobo
A dismissal with prejudice operates as a final adjudication on the merits for preclusion purposes. Airigan Solutions cannot refile the same infringement claims under US9968211B2 against Yuhuan Aobo. If the parties reached a licensing or settlement deal, those terms are confidential. The own-costs provision means no fee award flows back to either party, consistent with a negotiated resolution rather than a contested loss.
No refiling permittedYuhuan Aobo exits with finality — and without a fee award
Yuhuan Aobo secured a with-prejudice dismissal, eliminating any future infringement risk from Airigan Solutions on this patent for the same accused products. The absence of any fee-shifting under 35 U.S.C. § 285 suggests the case was not found exceptional, or more likely that both sides preferred a clean exit over continued litigation. The defendant’s legal exposure on US9968211B2 is now fully extinguished.
Claim extinguishedUS9968211B2 remains enforceable against other egg peeler sellers
The stipulated dismissal disposes only of claims against Yuhuan Aobo. US9968211B2 remains in force and Airigan Solutions retains full rights to enforce it against other manufacturers or retailers of competing egg peeler products. Sellers of NEGG-style devices — particularly those sourcing from Chinese OEM manufacturers — should treat this patent as actively enforced and conduct FTO analysis before commercialising similar products.

Official order — verbatim text
The stipulation invokes Rule 41(a)(1)(A)(ii), confirming that dismissal required mutual written consent because Yuhuan Aobo had already answered. The with-prejudice designation is legally significant: it bars Airigan Solutions from relitigating these claims against this defendant, functioning as a final judgment for claim preclusion purposes. The own-costs provision — expressly written into the stipulation — forecloses any subsequent fee motion under 35 U.S.C. § 285. No merits ruling, claim construction, or validity determination was reached.
US9968211B2 — NEGG® boiled egg peeler device
US9968211B2 (application no. US15/156785) protects the NEGG® brand boiled egg peeling device — a consumer kitchen tool designed to remove eggshells from hard-boiled eggs via a water-agitation mechanism. The patent covers the structural configuration of the device and its operational method, distinguishing it from conventional manual peeling. As a utility patent, it provides exclusivity over the claimed design elements and functional features of the peeling mechanism.
The NEGG® device achieved significant consumer traction in the kitchen gadget category, particularly through e-commerce channels. That commercial success makes US9968211B2 a strategically valuable enforcement asset: any manufacturer producing a functionally similar boiled egg peeler — particularly one using a comparable shaking or agitation mechanism — faces infringement exposure. The Yuhuan Aobo action demonstrates Airigan Solutions’ willingness to pursue Chinese OEM manufacturers directly, raising the risk profile for importers and private-label brands sourcing similar devices.
Should you run an FTO analysis against US9968211B2?
Any company manufacturing, importing, or selling boiled egg peeler devices — particularly handheld water-agitation style peelers — in the US market should treat US9968211B2 as a live enforcement risk. This case confirms Airigan Solutions actively monitors and litigates against competing products. OEM manufacturers in China supplying US brands, and Amazon marketplace sellers offering NEGG-style devices, are the most exposed categories.

What this case signals for the consumer kitchen gadget IP landscape
A swift, bilateral exit suggests commercial pragmatism — but the underlying patent remains a live enforcement tool.
Early dismissal without costs typically signals a negotiated exit, not a win
When both parties bear their own fees and the case closes in under six months, the public record is silent on any licensing terms. Competitors and distributors of egg peeler devices should not interpret this dismissal as a patent invalidity signal — US9968211B2 was never challenged on the merits in this proceeding.
The case name covers Morning Chef — whose status in the litigation is ambiguous
The docket names Morning Chef as a defendant, but the stipulated dismissal specifically addresses only Yuhuan Aobo Plastic Industry Co. IP professionals monitoring this matter should track whether separate claims against Morning Chef remain open or were resolved separately from this termination.
Airigan v MORNING — key questions answered
The dismissal with prejudice under Rule 41(a)(1)(A)(ii) permanently bars Airigan Solutions from refiling the same infringement claims against Yuhuan Aobo Plastic Industry Co. under US9968211B2. However, the patent itself remains valid and enforceable against other parties, and Airigan retains full rights to pursue other manufacturers or sellers of competing egg peeler products.
No validity determination was made. The case settled via stipulated dismissal before any merits ruling, claim construction hearing, or validity challenge. The patent’s validity was not adjudicated in this proceeding, meaning it carries the same presumption of validity it held at filing.
The stipulation expressly provides that all parties bear their own costs and counsel fees. This forecloses any subsequent motion for attorney fees under 35 U.S.C. § 285 or Fed. R. Civ. P. 54(d). It is consistent with a negotiated resolution where neither side sought a prevailing-party determination, likely to facilitate a clean commercial exit.
The accused products identified in the case include devices marketed as a boiled egg peeler, egg cracker, egg peeler, and NEGG® brand egg peeler. The defendant Yuhuan Aobo Plastic Industry Co. is a Chinese plastics manufacturer, suggesting the accused products were manufactured in China and imported or sold in the US market.
The public record of the stipulated dismissal specifically names Yuhuan Aobo Plastic Industry Co. as the party to the dismissal. Morning Chef is named as a defendant in the case caption but is not expressly addressed in the available termination stipulation. IP professionals should independently verify the docket for any separate orders or stipulations addressing Morning Chef’s status in the litigation.
