Shenzhen Juxinli v. Interlink Products: Rain Shower Head Patent Case Voluntarily Dismissed
Shenzhen Juxinli Technology filed a patent infringement action against Interlink Products International in the Western District of Washington, asserting two shower head patents. The case was voluntarily dismissed within 118 days, before Defendants served an answer or motion for summary judgment.
Rain Shower Head Patent Suit Ends in Voluntary Dismissal After 118 Days
Shenzhen Juxinli Technology Co. Ltd., a Shenzhen-based technology company, filed suit against Interlink Products International, Inc. and individual Eli Zhadanov in the Western District of Washington on 30 December 2025, asserting infringement of US11992850B2 and US12485435B2. The asserted patents relate to rain shower head technology, and the complaint identified multiple Amazon ASINs (B0DQHFG94H, B0DQHHCGHQ, B0DQHJR1YB, B0FH1577WQ) as accused products.
The recorded Basis of Termination is 'Voluntary dismissal.' The docket order states that plaintiff filed a notice pursuant to Fed. R. Civ. P. 41(a)(1)(A)(i) voluntarily dismissing with prejudice all claims against Interlink Products International, Inc. and Eli Zhadanov, noting that defendants had not served an answer or motion for summary judgment and that plaintiff had not previously dismissed any federal- or state-court action against defendants based on the same claims.
The case resolved in just 118 days, before defendants were required to respond on the merits. What drove the dismissal — whether a private agreement, commercial resolution, or strategic reassessment — is not disclosed in the available public record. The specific terms, if any, governing the parties' relationship following dismissal are likewise not disclosed.

US11992850B2 & US12485435B2 — Rain Shower Head Technology
Any company manufacturing, importing, distributing, or selling rain shower heads — particularly through Amazon or other e-commerce channels — should conduct a freedom-to-operate analysis against US11992850B2 and US12485435B2. This case demonstrates that Juxinli is actively enforcing these patents, and no court has yet narrowed or invalidated the asserted claims. The risk is live for the entire supply chain, from OEM manufacturers in China to US-based Amazon sellers.
Official order — verbatim text
The docket notice invokes Rule 41(a)(1)(A)(i), the self-executing plaintiff dismissal mechanism available before any responsive pleading is served. The order characterises the dismissal as 'with prejudice.' No merits ruling, claim construction, or validity determination was entered, meaning the substantive questions raised by the infringement allegations against Interlink Products International and Eli Zhadanov remain judicially unresolved.
Voluntary dismissal: what the resolution means for both parties
Rule 41(a)(1)(A)(i): self-executing voluntary dismissal
A notice filed under Fed. R. Civ. P. 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order, provided the defendant has not yet served an answer or motion for summary judgment. This is the most straightforward exit route in US federal litigation. The notice is self-executing — no judicial approval is required and it takes effect upon filing.
No court order requiredThe record is split: Basis says 'Voluntary dismissal'; order says 'with prejudice'
The recorded Basis of Termination is 'Voluntary dismissal' without specifying prejudice. The verbatim docket order states dismissal 'with prejudice.' A with-prejudice dismissal bars the plaintiff from refiling the same claims against these defendants. A without-prejudice dismissal would preserve that right. The public record as captured presents both characterisations; readers should consult the original docket for the operative filing.
Prejudice status: review docketInterlink and Zhadanov exit without a merits adjudication
Defendants were dismissed before filing any responsive pleading. No finding of non-infringement or invalidity was entered. If the dismissal is operative with prejudice as stated in the order, defendants receive finality against re-litigation of these specific claims by this plaintiff. No cost or fee award is disclosed in the available record.
No merits ruling enteredAmazon-listed shower products: IP risk remains unresolved for the sector
The accused products were identified by Amazon ASINs, consistent with enforcement patterns targeting e-commerce sellers of shower hardware. The patents-in-suit remain in force. Competitors and distributors selling rain shower heads — particularly via Amazon — should monitor both US11992850B2 and US12485435B2, as no validity or claim scope determination was reached in this action.

R&D signals in the shower head and bath hardware IP space
Forward-looking patent and innovation intelligence derived from Shenzhen Juxinli's enforcement of rain shower head patents US11992850B2 and US12485435B2 against Interlink Products International.
Juxinli's shower head patent portfolio and filing activity
Shenzhen Juxinli has filed at least two US patents covering rain shower head technology, with sequential applications suggesting an active continuation strategy. Monitoring their USPTO prosecution history and pending applications may reveal the full boundaries of their IP position and where they are seeking to expand coverage in shower hardware.
Active filer — continuation strategyPatent filing trends in rain shower head and handheld shower technology
The rain shower head category has attracted increasing patent activity from Chinese manufacturers targeting US markets. Filing trends around nozzle design, water flow control, and integrated filtration represent active innovation sub-domains. Companies entering this space should map the density of existing filings before committing to product development.
High-filing consumer hardware sub-sectorInterlink Products International's IP position in bath hardware
Interlink Products International was named as defendant in this shower head patent action. Assessing their own patent portfolio and any defensive filings in bath hardware technology reveals whether they hold blocking positions or are primarily reliant on design freedom. Their IP posture shapes competitive risk for adjacent product developers.
Defensive IP audit recommendedDesign-around opportunities adjacent to US11992850B2 and US12485435B2
With two patents asserted and no claim construction ruling on record, the precise boundaries of Juxinli's claims remain undefined in litigation. White-space analysis around the application numbers US17/247425 and US18/665994 — covering alternative nozzle geometries, flow regulators, and mounting mechanisms — may surface design-around opportunities for manufacturers seeking to enter the market safely.

What this case signals for the shower hardware IP landscape
A swift voluntary dismissal over Amazon-listed shower products points to active IP enforcement in the consumer bath hardware space.
Amazon ASIN-targeted enforcement is a growing vector in consumer hardware IP
Juxinli identified accused products by their Amazon ASINs — a pattern consistent with IP enforcement strategies aimed at e-commerce sellers. Companies distributing shower hardware on Amazon marketplaces should assess their exposure to US11992850B2 and US12485435B2 before scaling product listings.
Early dismissal leaves patent validity and claim scope entirely open
Because the case ended before any responsive pleading, no court assessed the validity, scope, or enforceability of either asserted patent. Both patents retain their presumption of validity. Any party in the rain shower head supply chain should treat these patents as live enforcement risk pending any future IPR or litigation.
Shenzhen v INTERLINK — key questions answered
Shenzhen Juxinli asserted two patents: US11992850B2 (application US17/247425) and US12485435B2 (application US18/665994), both relating to rain shower head technology. The accused products were identified by Amazon ASINs B0DQHFG94H, B0DQHHCGHQ, B0DQHJR1YB, and B0FH1577WQ.
The recorded Basis of Termination is 'Voluntary dismissal.' The docket order states that plaintiff Shenzhen Juxinli filed a notice under Fed. R. Civ. P. 41(a)(1)(A)(i) dismissing all claims with prejudice against Interlink Products International and Eli Zhadanov. The case closed on 27 April 2026, 118 days after filing.
No. A voluntary dismissal is a procedural resolution and carries no finding on patent validity or infringement. US11992850B2 and US12485435B2 remain in force with their presumption of validity intact. No court assessed claim scope or validity in this action.
Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss before the defendant serves an answer or motion for summary judgment, without court approval. Here, the order characterises the dismissal as 'with prejudice,' which — if operative — bars Juxinli from refiling the same claims against these defendants. No cost or fee award is disclosed in the available record.
Manufacturers, importers, and Amazon sellers of rain shower heads should treat both patents as live enforcement risk. This case demonstrates active enforcement by Juxinli, and no invalidity or non-infringement finding was made. A freedom-to-operate analysis against these patents is advisable before launching or scaling products in this category.
