Dongguan Guardian Technology v. Schedule A Defendants: Watch Case Design Patent Dismissed in 14 Days
Dongguan Guardian Technology Co., Ltd. filed suit in the District of Colorado asserting design patent USD1002391S — covering a watch case — against a class of unnamed online marketplace defendants. The action was voluntarily dismissed without prejudice just 14 days after filing, before any defendant responded.
A 14-day Schedule A watch design suit that never got off the ground
On August 11, 2025, Dongguan Guardian Technology Co., Ltd., a Chinese consumer electronics manufacturer, filed a design patent infringement action in the U.S. District Court for the District of Colorado before Judge Philip A. Brimmer. The asserted patent, USD1002391S (application number 29/824538), protects the ornamental design of a watch case. Defendants were identified collectively as corporations, partnerships, and unincorporated associations listed on Schedule A — a common enforcement tactic used against online marketplace sellers.
On August 25, 2025 — just 14 days after filing — plaintiff’s counsel at Alioth Law LLP filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The notice expressly states the dismissal is without prejudice. No defendant had filed an answer, motion for summary judgment, or any other responsive pleading at that point, meaning the plaintiff retained the procedural right to refile the same claims at a later date.
A 14-day window between filing and dismissal is notably brief even by Schedule A litigation standards, where early settlements and strategic withdrawals are common. The absence of any defendant appearance suggests the dismissal may reflect an out-of-court resolution, a decision to refile in a different venue, or a reassessment of litigation strategy — though the public record does not disclose the specific reason. The without-prejudice posture means the watch case design patent remains an active enforcement asset.

Voluntarily dismissed: what the FRCP 41 notice means for both parties
FRCP 41(a)(1)(A)(i): plaintiff’s unilateral right to dismiss
Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. Because no Schedule A defendant filed any responsive pleading here, Dongguan Guardian exercised this right unilaterally. The dismissal takes effect upon filing the notice — no judicial approval is required.
No court order neededWithout prejudice confirmed — but what does that mean?
The notice expressly states ‘without prejudice,’ meaning the plaintiff retains the right to refile the same design patent claims against the same or different defendants. A with-prejudice dismissal would permanently bar refiling on identical claims. Here, USD1002391S remains an enforceable asset. The public record does not disclose whether a private settlement was reached alongside the dismissal.
Refiling rights preservedSchedule A defendants face no judgment — but no permanent closure
No named defendant incurred a damages award, injunction, or adverse costs ruling. However, without-prejudice status means sellers offering products that potentially infringe USD1002391S remain exposed to a future action. Defendants who believed they had a strong non-infringement or invalidity argument have no judicial ruling to point to as precedent.
No judgment, but risk persistsWatch case design IP: enforcement risk remains alive
Schedule A campaigns targeting watch accessories on online marketplaces are a well-established enforcement pattern in the consumer electronics space. A swift voluntary dismissal without prejudice can signal a private settlement with certain sellers or a venue strategy shift. Competing sellers and product designers working with similar watch case aesthetics should monitor USD1002391S for refiling activity.

Official order — verbatim text
The voluntary dismissal notice cites FRCP 41(a)(1)(A)(i) and expressly confirms the action is dismissed without prejudice. This phrasing is legally precise: it confirms the plaintiff’s unilateral authority to end the case at this pre-answer stage and preserves all claims for potential refiling. The absence of any mention of a settlement agreement, defendant identity, or damages in the public filing means the strategic rationale behind the 14-day withdrawal remains unknown from the record.
USD1002391S — Ornamental design for a watch case
USD1002391S, filed under application number 29/824538, is a U.S. design patent protecting the ornamental appearance of a watch case. Design patents cover the visual, non-functional characteristics of a product as depicted in the patent drawings — not the underlying mechanical or electronic functionality. In the consumer wearables and accessories sector, watch case design patents are frequently asserted against overseas manufacturers and online marketplace sellers whose products share similar silhouettes, bezels, or surface treatments.
For Dongguan Guardian Technology, USD1002391S represents a strategic IP asset in a highly competitive online marketplace environment where design differentiation is commercially significant. The patent’s filing date and application number suggest it is a relatively recent design registration, potentially timed to establish prior rights against a wave of copycat sellers. Any manufacturer or importer of watch cases with overlapping ornamental features — particularly those selling on Amazon or similar platforms — should treat this patent as an active enforcement risk, regardless of the current dismissal.
Should you run an FTO analysis against USD1002391S?
Any company designing, importing, or distributing watch cases for the U.S. market should assess clearance against USD1002391S. Because design patent infringement is determined by the ‘ordinary observer’ test — whether an average consumer would find the designs substantially similar — even products that differ functionally may infringe if the ornamental appearance is close. The without-prejudice dismissal means Dongguan Guardian retains full rights to enforce, and Schedule A campaigns can resume rapidly.
PatSnap Eureka’s FTO Search Agent can map the claim scope of USD1002391S against your product drawings, identify prior art that may limit the patent’s effective scope, and surface related design patent families from the same assignee. For product teams launching new watch case SKUs, running this analysis before market entry is materially less costly than defending a TRO motion in federal court.

What this case signals for watch design patent enforcement on online marketplaces
A 14-day Schedule A action is rarely the end of an enforcement campaign — it is often a calibration point.
Without-prejudice dismissal keeps USD1002391S fully loaded for refiling
Because no defendant responded and dismissal was filed under FRCP 41(a)(1)(A)(i), Dongguan Guardian retains all enforcement options. IP teams tracking consumer electronics design patents should flag USD1002391S as an active risk asset, not a resolved dispute.
Schedule A litigation in Colorado: a pattern worth monitoring
Filing against Schedule A defendants in the District of Colorado is a deliberate venue choice. When a plaintiff dismisses quickly without prejudice, it often suggests either a targeted seller settled privately or the plaintiff is reassessing defendant identification — not that the campaign has ended.
Dongguan v Corporations — key questions answered
The dismissal without prejudice means Dongguan Guardian Technology retains the right to refile the same design patent infringement claims based on USD1002391S against the same or different defendants at a future date. No court judgment was entered, no defendant was adjudicated liable, and no damages or injunctions were issued. The patent remains fully enforceable.
USD1002391S is a U.S. design patent filed under application number 29/824538, owned by Dongguan Guardian Technology Co., Ltd. It protects the ornamental visual design of a watch case. Design patents cover how a product looks — not how it functions — and infringement is assessed by whether an ordinary observer would find the designs substantially similar.
The District of Colorado is a recognised venue for Schedule A design patent enforcement actions. Schedule A cases name unknown or pseudonymous online sellers collectively, allowing plaintiffs to seek temporary restraining orders and asset freezes before defendants are individually identified. The choice of Colorado likely reflects plaintiff counsel’s venue preference rather than any defendant’s physical location.
Yes. Because the dismissal was expressly without prejudice and filed before any defendant served a responsive pleading, FRCP 41(a)(1)(A)(i) preserves the plaintiff’s right to refile identical claims. There is no statutory bar to a new action on USD1002391S against the same or newly identified defendants, subject to the applicable statute of limitations.
Sellers offering watch cases with ornamental designs similar to those depicted in USD1002391S remain at risk of a refiled action. A without-prejudice dismissal does not provide any legal safe harbour. Sellers who received takedown notices or asset freezes during the 14-day window should treat the dismissal as a pause, not a clearance, and consider obtaining an FTO opinion covering the patent’s design claims.
