Shandong Yunxiang v. Purple Innovation: Design Patent Dismissed in 73 Days
A Chinese technology company alleged Purple Innovation infringed design patent USD990930S covering seat cushion configurations. The case, filed in the Northern District of California, was voluntarily dismissed without prejudice just 73 days after filing — before Purple Innovation answered or moved for summary judgment.
Design patent dispute over seat cushion aesthetics ends before first responsive pleading
On 11 February 2025, Shandong Yunxiang Century Intelligent Technology Co., Ltd. — joined by co-plaintiff Shandong Jiuhui Information Technology Co., Ltd. — filed an infringement action in the Northern District of California against Purple Innovation, LLC. The complaint centred on design patent USD990930S (U.S. Application No. 29/779618), which protects the ornamental design of a seat cushion. Purple Innovation’s products named in the suit include BulbHead, Hvllyan US Seat Cushions, and KYSMOTIC-US Seat Cushions.
On 25 April 2025, the plaintiffs filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), terminating all claims without prejudice. The dismissal was filed before Purple Innovation had answered or moved for summary judgment, which is a prerequisite for a plaintiff to exercise this unilateral right of dismissal. The order confirmed each party would bear its own costs, expenses, and attorneys’ fees — indicating no financial settlement terms were publicly recorded.
The 73-day lifecycle is notably brief, suggesting the dispute may have been resolved through private negotiation, licensing discussions, or a strategic reassessment by the plaintiffs following the filing. Because the dismissal is without prejudice, the plaintiffs retain the right to refile the same claims, which meaningfully preserves their enforcement options. The public record does not disclose whether any commercial agreement accompanied the dismissal.
Filing to Voluntary dismissal in 73 days
73 days — resolved before defendant filed any responsive pleading
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): unilateral dismissal before any answer
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss its action without a court order at any time before the defendant serves an answer or a motion for summary judgment. Because Purple Innovation had not yet done either, Shandong Yunxiang exercised this right unilaterally. The dismissal takes effect upon filing — no judicial approval is required — making it one of the fastest procedural exits available in U.S. federal litigation.
No court order requiredWithout prejudice confirmed — refiling remains an option
The notice expressly states the dismissal is WITHOUT PREJUDICE, meaning the plaintiffs are not barred from reasserting the same claims against Purple Innovation in a future action. This is meaningfully different from a dismissal with prejudice, which would extinguish the claims permanently. The public record confirms the without-prejudice characterisation, preserving Shandong Yunxiang’s full enforcement rights over USD990930S.
Refiling rights preservedPlaintiffs exit cleanly — enforcement posture intact
Shandong Yunxiang and Shandong Jiuhui exit the litigation without any adverse judgment on the merits of their design patent. The without-prejudice dismissal means they retain the ability to refile if negotiations fail or commercial circumstances change. The own-costs arrangement means no financial penalty attaches to the withdrawal, though litigation costs incurred to date are not recoverable from Purple Innovation.
No adverse ruling on meritsPurple Innovation avoids merits ruling — but patent threat persists
Purple Innovation obtains a clean exit from this action without any finding of infringement, and without bearing the plaintiffs’ legal costs. However, because the dismissal is without prejudice, the design patent USD990930S remains a live enforcement risk. Companies in the seat cushion and comfort products space should note that a without-prejudice dismissal is not a clearance — the same patent may be asserted again, potentially in the same or a different venue.

Official order — verbatim text
The dismissal notice invokes FRCP 41(a)(1)(A)(i) and explicitly characterises the termination as without prejudice, with each party bearing its own costs. This phrasing confirms no merits adjudication occurred: the court made no finding on infringement, validity, or claim scope of USD990930S. The without-prejudice designation is legally significant — it resets the parties to their pre-litigation positions while leaving the plaintiffs’ enforcement rights fully intact. Purple Innovation obtains no estoppel or res judicata protection from this exit.
USD990930S — Ornamental Seat Cushion Design
USD990930S (filed under U.S. Application No. 29/779618) is a U.S. design patent protecting the ornamental appearance of a seat cushion. Design patents under 35 U.S.C. § 171 cover the visual, non-functional characteristics of an article of manufacture — in this case, the specific shape, configuration, or surface ornamentation of a seat cushion product. Design patents typically grant protection for 15 years from issuance and are infringed when an ordinary observer, familiar with the prior art, would find the accused product substantially similar in appearance to the patented design.
In the highly competitive U.S. consumer comfort products market, design patents on seat cushion configurations can be asserted broadly against private-label and white-label sellers operating on e-commerce platforms. The products named in this action — BulbHead, Hvllyan US Seat Cushions, and KYSMOTIC-US Seat Cushions — are consistent with the multi-brand e-commerce retail model, where similar underlying products are sold under different brand names. This dynamic makes design patent enforcement particularly potent, as a single patent can be wielded against multiple product listings and sellers simultaneously.
Should your product team run an FTO against USD990930S?
Any company designing, importing, or selling seat cushions or ergonomic comfort products in the U.S. market should consider a freedom-to-operate review against USD990930S, particularly if their products share visual characteristics with cushion designs originating from Chinese manufacturers. The without-prejudice dismissal in this case means the patent remains active enforcement leverage — and e-commerce sellers offering similar SKUs under multiple brand names are especially exposed to design patent claims based on substantial similarity.
PatSnap Eureka’s FTO Search Agent can map your product’s ornamental design against the claim scope of USD990930S and identify prior art that may support a design-around or validity challenge. Eureka can also surface related design patent filings from the Shandong Yunxiang portfolio and flag co-pending applications that could extend enforcement risk beyond this single patent — giving your legal and product teams a complete picture before commercialisation decisions are made.

What this case signals for the seat cushion and consumer product IP landscape
Design patent enforcement by offshore patent holders against U.S. consumer brands is a growing pattern — this case illustrates both the speed and the limits of early-stage exits.
Early dismissals without prejudice are not clearances — monitor for refiling
A Rule 41(a)(1)(A)(i) dismissal is procedurally neutral. USD990930S remains valid and enforceable. Purple Innovation and similarly positioned comfort-product companies should maintain a watch on this patent and related design filings from the Shandong Yunxiang portfolio to anticipate any refiling or related assertions.
Design patents in consumer goods carry asymmetric litigation risk
Design patents such as USD990930S can be asserted broadly across visually similar products. Companies selling seat cushions or ergonomic accessories under third-party or white-label brands — as suggested by the BulbHead, Hvllyan, and KYSMOTIC products named here — should ensure their supply chain agreements include IP indemnification clauses and that they have conducted FTO reviews on their ornamental designs.
Shandong v Purple — key questions answered
The case was voluntarily dismissed without prejudice on 25 April 2025 under FRCP 41(a)(1)(A)(i). No merits ruling was issued. Each party bears its own costs. The plaintiffs retain the right to refile claims based on design patent USD990930S against Purple Innovation.
The asserted patent is USD990930S (U.S. Application No. 29/779618), a U.S. design patent covering the ornamental design of a seat cushion. Design patents protect the visual, non-functional appearance of a product and are infringed when an ordinary observer would find the accused product substantially similar to the patented design.
No. A dismissal without prejudice means no court has ruled on the merits of the infringement claim. USD990930S remains a valid and enforceable patent, and the plaintiffs may refile the same claims. Purple Innovation obtained no estoppel or res judicata protection from this dismissal.
The complaint named three products: BulbHead, Hvllyan US Seat Cushions, and KYSMOTIC-US Seat Cushions. These are consistent with multi-brand or white-label e-commerce product listings in the seat cushion and comfort products category.
The public record does not disclose the specific reason. The speed — 73 days before any responsive pleading — is consistent with private settlement or licensing negotiations, or a strategic reassessment by the plaintiffs. The own-costs clause in the dismissal notice suggests no publicly disclosed financial resolution was reached.
