Shenzhenshi Santian v. Zhiyong Qiu: Phone Holder Design Patent Dismissed
A Chinese consumer goods company filed a design patent infringement suit in the Northern District of California over a phone holder sold on Amazon. After 267 days, the plaintiff voluntarily dismissed the case without prejudice before the defendant had answered — leaving the door open for future action.
Design Patent Dispute Over Amazon Phone Holder Ends Pre-Answer
On January 23, 2025, Shenzhenshi Santian Shiye Youxiangongsi — a Shenzhen-based commercial entity — filed an infringement action in the U.S. District Court for the Northern District of California, asserting design patent USD981468S (application no. 29/849136) against individual defendant Zhiyong Qiu. The accused product was a phone holder listed on Amazon.com under ASIN B0CJTL7Q3J, placing this dispute squarely within the rapidly contested e-commerce design patent enforcement landscape.
The case closed on October 17, 2025, when the plaintiff filed a notice of voluntary dismissal without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). Critically, dismissal was effectuated before Zhiyong Qiu served either an answer or a motion for summary judgment, meaning the dismissal was self-executing and required no court order. Neither party received a merits determination, and no costs were assessed against either side.
The 267-day duration before dismissal is notable given that the exit occurred at the earliest possible procedural stage, suggesting settlement discussions, a licensing arrangement, or a strategic reassessment may have occurred off the record. The absence of defendant counsel on the public docket and the pre-answer timing leave the precise motivation unclear. Because dismissal was without prejudice, Shenzhenshi Santian retains the right to reassert USD981468S against Qiu or other parties in a future action, subject to applicable statutes of limitation.
Filing to Voluntary dismissal in 267 days
267 days — resolved before defendant filed any responsive pleading
Voluntarily dismissed: what the Rule 41(a) exit means for both parties
Rule 41(a) dismissal: self-executing before any responsive pleading
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or summary judgment motion. That threshold was met here. The dismissal is automatic upon filing — the court has no discretion to block it — and carries no merits ruling. This is the cleanest procedural exit available in federal civil litigation.
No court order requiredWithout prejudice: the public record does not reveal the full story
A dismissal without prejudice means the plaintiff has not waived its claims — it may refile the same infringement action against the same or different defendants, subject to the statute of limitations. The public record is silent on whether any settlement, licensing deal, or commercial resolution accompanied this dismissal. Parties sometimes agree to resolve disputes privately while filing a without-prejudice dismissal to close the docket, but no such agreement is disclosed here.
Refiling right preservedQiu faces no judgment — but the threat is not extinguished
Zhiyong Qiu avoids any adverse ruling, injunction, or damages award. No costs were assessed. However, because dismissal is without prejudice, Qiu cannot treat this as a final resolution. If the underlying Amazon listing or design at issue remains active, the plaintiff retains the ability to reinitiate proceedings. Absent a formal settlement or license, the commercial risk profile for Qiu has not fundamentally changed.
No judgment — risk persistsAmazon design patent enforcement: a pattern of pre-answer exits
Design patent suits targeting Amazon marketplace sellers frequently resolve or dissolve before merits adjudication, often because defendants remove listings, agree to cease-and-desist terms, or negotiate licenses quickly. This case is consistent with that pattern. For Amazon sellers and their counsel, the case reinforces that receiving a complaint — even without a court judgment — can be sufficient commercial leverage to achieve the plaintiff’s objective without full litigation.

Official order — verbatim text
The dismissal notice closely tracks the statutory language of FRCP 41(a)(1)(A)(i), emphasizing that no answer or summary judgment motion had been served — the precise condition that makes the dismissal self-executing. The explicit ‘WITHOUT PREJUDICE’ designation is legally significant: it forecloses any argument that the plaintiff’s claims are extinguished. No merits finding, claim construction, or validity ruling was ever made with respect to USD981468S.
USD981468S — Consumer Phone Holder Ornamental Design
USD981468S, filed under application number 29/849136, is a U.S. design patent protecting the ornamental appearance of a phone holder — the type of mounting or grip accessory commonly sold through e-commerce platforms. Design patents protect only the visual, non-functional aspects of a product, meaning the scope of protection turns on how an ordinary observer would perceive the overall design, not on mechanical or functional features. The application number places it in the Design Patent series handled by the USPTO.
Design patents covering commodity consumer electronics accessories represent a significant and growing enforcement vector on Amazon and similar marketplaces. A single design patent can be asserted against dozens of visually similar competing listings, making them cost-effective enforcement tools for manufacturers protecting product aesthetics. For competitors, the key risk is that design patent infringement is assessed under the ‘ordinary observer’ test — a relatively low bar that can capture products differing in minor functional respects but sharing overall visual similarity.
Should your team run an FTO search against USD981468S?
Any brand, Amazon seller, or product team sourcing or marketing phone holders, dashboard mounts, desk grips, or similar mobile device accessories should assess design clearance against USD981468S. Because this patent survived this litigation without any invalidity challenge, it carries full presumption of validity. The ‘without prejudice’ dismissal means the plaintiff can and may target other sellers with visually similar products — making proactive FTO analysis commercially essential before a new SKU goes live.
PatSnap Eureka’s FTO Search Agent can map the ornamental design scope of USD981468S against your product’s visual profile, surface prior art that could support a future invalidity challenge, and identify related design patent families filed by Shenzhenshi Santian or connected entities. Eureka also monitors for new filings and Amazon enforcement actions in the phone holder and consumer electronics accessory space, giving product and IP teams early warning before a complaint lands.

What this case signals for the Amazon design patent IP landscape
Pre-answer voluntary dismissals in Amazon marketplace design patent suits reveal a litigation strategy built on commercial leverage, not courtroom resolution.
Design patent suits against Amazon sellers rarely reach trial
This case illustrates a well-documented enforcement pattern: file suit, exert commercial pressure, then exit before costly discovery begins. For IP teams monitoring competitor enforcement activity, a voluntary dismissal without prejudice should be treated as a pause, not a resolution. The asserting party retains full rights to refile.
Pre-answer timing signals a leverage-driven litigation strategy
The plaintiff dismissed before the defendant even engaged counsel on the docket. This asymmetry — a represented plaintiff versus an apparently unrepresented individual seller — is consistent with a strategy designed to prompt a quick commercial response rather than litigate to judgment. Product teams sourcing from Shenzhen-based suppliers should audit design patent clearance before Amazon listings go live.
