Dongguan Guanyi v. Schedule A Defendants: LED Light String Patent Voluntarily Dismissed
Dongguan Guanyi Light-decoration Co., Ltd. filed suit in the Northern District of Illinois asserting US11408585B1 against a group of unnamed online marketplace defendants over LED light strings and bulbs. The case was voluntarily dismissed in just 58 days — a timeline consistent with rapid Schedule A enforcement tactics.
Schedule A LED light string enforcement ends in 58-day voluntary dismissal
On 23 October 2023, Dongguan Guanyi Light-decoration Co., Ltd., a Chinese lighting manufacturer, filed an infringement action in the U.S. District Court for the Northern District of Illinois (Case No. 1:23-cv-15248) before Judge Andrea R. Wood. The suit asserted U.S. Patent No. 11,408,585 B1 (application no. US17/404988) against an undisclosed set of defendants identified only as 'The Partnerships and Unincorporated Associations Identified on Schedule A of the Complaint' — the standard placeholder format used in multi-defendant online marketplace cases. Products at issue spanned C7, C9, G30, G40, G50, and S14 LED light strings, LED mini light strings, E26 light strings, extension cords, power cords, and related lighting accessories.
The recorded basis of termination is Voluntary dismissal. The docket order states that plaintiff's counsel filed a notice pursuant to Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure voluntarily dismissing with prejudice any and all claims raised in the complaint against the named defendants. The case closed on 20 December 2023, 58 days after filing. No defendant agents or law firms appear in the public record, suggesting the defendants may not have formally appeared before dismissal was filed. The specific terms underlying the resolution are not disclosed in the available record.
A 58-day lifespan is consistent with the pace of Schedule A enforcement campaigns, where plaintiffs often secure a temporary restraining order or preliminary injunction early, then resolve individual defendants through private agreements before trial. Whether any such resolution drove the dismissal here is not disclosed in the public record. The absence of defendant representation on the docket and the 'with prejudice' language in the Rule 41 notice may be commercially significant, but the specific terms are not disclosed.

US11408585B1 — LED light string and decorative bulb technology
Any company manufacturing, importing, distributing, or selling LED light strings — including C7, C9, G30, G40, G50, S14, E26, or mini LED string formats — in the U.S. market should assess its freedom-to-operate position against US11408585B1. The patent has already been deployed in active litigation against marketplace sellers, and the voluntary dismissal does not limit its enforceability. Online marketplace sellers and private-label importers are particularly exposed given the Schedule A enforcement model used here.
Official order — verbatim text
The Rule 41(a)(1)(A)(i) notice was filed by plaintiff's counsel and states dismissal with prejudice of all claims against the Schedule A defendants. Because no defendant appears to have filed an answer or summary judgment motion, plaintiff was entitled to file this notice as of right without court approval. The recorded basis of termination is Voluntary dismissal; the notice text additionally characterises the dismissal as with prejudice. The specific terms underlying the resolution are not disclosed in the available record.
Voluntary dismissal: what the resolution means for both parties
Rule 41(a)(1)(A)(i): plaintiff-initiated dismissal without court order
A Rule 41(a)(1)(A)(i) notice may be filed by a plaintiff as of right before the opposing party serves an answer or a motion for summary judgment. It requires no court approval. Here, plaintiff filed such a notice and stated the dismissal was with prejudice. The recorded basis of termination is Voluntary dismissal; the docket order additionally characterises it as with prejudice. The specific terms are not disclosed in the available record.
Rule 41(a)(1)(A)(i) noticeWith prejudice vs. without prejudice: what the public record says
The recorded basis of termination is Voluntary dismissal, which does not specify prejudice. The Rule 41 notice text states the dismissal was with prejudice. A with-prejudice dismissal bars the plaintiff from re-filing the same claims against the same defendants. The public record does not disclose whether a settlement or licence agreement underlies this characterisation. The specific terms are not disclosed in the available record.
Prejudice qualifier in noticeNo formal appearance: defendants' exposure and what dismissal means for them
No defendant agents or law firms appear in the docket record, suggesting the Schedule A defendants did not formally appear before the dismissal was filed. If the dismissal is with prejudice as stated in the Rule 41 notice, defendants face no further liability on these specific claims from this plaintiff. Whether any private commercial terms accompanied the dismissal is not disclosed in the available record.
No defendant appearance recordedSchedule A enforcement dynamics in LED lighting IP
Schedule A cases targeting LED light string sellers on online marketplaces are a common enforcement vehicle for lighting IP holders. A rapid 58-day resolution — before any defendant formally appeared — is consistent with early-stage settlement or account suspension leverage. US11408585B1 remains a live patent asset. Third-party sellers of C7, C9, G-series, and S14 LED light strings should assess their FTO posture against this patent.

R&D signals in the LED decorative lighting patent space
This case surfaces active patent enforcement activity by Chinese LED lighting OEMs in the U.S. — here are the forward-looking IP and R&D signals that matter for the sector.
Dongguan Guanyi's U.S. patent filing activity in LED lighting
Dongguan Guanyi's enforcement of US11408585B1 suggests an active U.S. IP strategy beyond a single patent. Mapping the company's full U.S. patent portfolio reveals the breadth of its claimed innovations in LED string light construction, electrical connectors, and decorative bulb formats — and may indicate where further enforcement actions could emerge.
Portfolio mapping signalFiling trends in LED decorative string light patent claims
Patent filings covering LED string light configurations — including C7, C9, G-series, and S14 formats — have grown alongside the commoditisation of LED technology. Understanding claim density and filing velocity in this space helps product teams identify crowded claim areas and potential white space for design-around strategies.
LED string light claim densityHow marketplace LED light sellers are building defensive IP
Schedule A defendants in LED lighting cases are typically unrepresented marketplace sellers with no patent portfolio of their own. This asymmetry is commercially significant: sellers with even modest utility or design patent portfolios are better positioned to negotiate or deter enforcement. Tracking defensive patent activity among major LED string light importers signals a shift in market IP posture.
Defensive filing gapAdjacent innovation opportunities near LED string light IP
Beyond bulb configurations, adjacent claim space in LED decorative lighting includes smart connectivity, weatherproofing, energy-harvesting connectors, and modular string architectures. These areas show lower claim density relative to standard C7/C9/G-series formats and may represent protectable white space for manufacturers seeking to differentiate and build IP defensive moats.

What this case signals for the LED lighting IP enforcement landscape
Rapid Schedule A dismissals in N.D. Illinois often mask private resolutions — this case follows that pattern closely.
58-day Schedule A cases rarely end without off-docket resolution
When a Schedule A infringement action closes this quickly — before any defendant appears — it typically signals an early private agreement or marketplace account action rather than a clean walk-away. IP teams monitoring LED lighting enforcement should treat rapid dismissals as commercially resolved, not abandoned.
US11408585B1 remains enforceable: FTO review warranted for LED string sellers
The voluntary dismissal does not invalidate or limit the scope of US11408585B1. Any company manufacturing, importing, or selling C7, C9, G-series, or S14 LED light strings in the U.S. market should conduct a freedom-to-operate analysis against this patent before expanding product lines or marketplace listings.
Dongguan v Partnerships — key questions answered
The case was voluntarily dismissed. Plaintiff Dongguan Guanyi filed a Rule 41(a)(1)(A)(i) notice on or around 20 December 2023 — 58 days after filing — stating that all claims were dismissed with prejudice against the Schedule A defendants. The recorded basis of termination is Voluntary dismissal. The specific terms underlying the resolution are not disclosed in the available record.
The asserted patent is U.S. Patent No. 11,408,585 B1 (application no. US17/404988). Products identified in the complaint include C7 and C9 LED bulbs and light strings, G30, G40, G50, and S14 light strings, E26 light strings, LED mini light strings, extension cords, power cords, and lighting accessories.
The defendants are identified only as 'The Partnerships and Unincorporated Associations Identified on Schedule A of the Complaint' — the standard placeholder format used in multi-defendant online marketplace enforcement actions. No defendant agents or law firms appear in the public docket record.
No. A voluntary dismissal resolves the litigation between the named parties but does not affect the validity or enforceability of the underlying patent. US11408585B1 remains a granted U.S. patent and can be asserted in future proceedings against other parties. Companies selling or importing LED light strings covered by the patent's claims should conduct a freedom-to-operate analysis.
The Rule 41(a)(1)(A)(i) notice states the dismissal was with prejudice. A with-prejudice dismissal generally bars the plaintiff from re-filing the same claims against the same defendants. The recorded basis of termination is Voluntary dismissal, which does not itself specify the prejudice qualifier. The specific terms underlying the dismissal are not disclosed in the available public record.
