VTINVA v. Zhenzhen Zhu: Remote Control Design Patent Dismissed With Prejudice
Sichuan Xinxiangyuantong Technology Co. Ltd. (VTINVA) filed suit against individual defendant Zhenzhen Zhu in the Eastern District of Texas, asserting design patent USD971180S over the VTINVA Remote Control. The case ended after 379 days when both parties jointly stipulated to dismissal with prejudice, each bearing their own costs and attorneys’ fees.
Design Patent Dispute Over Remote Control Ends in Mutual Walk-Away
On October 31, 2024, Sichuan Xinxiangyuantong Technology Co. Ltd., operating under the brand name VTINVA, filed an infringement action against Zhenzhen Zhu in the U.S. District Court for the Eastern District of Texas (Case No. 4:24-cv-00977), presided over by Judge Sean D. Jordan. The asserted patent — USD971180S, filed as application US29/845876 — covers the ornamental design of the VTINVA Remote Control. VTINVA was represented by YoungZeal LLP, while Zhu retained Bayramoglu Law Offices LLC.
The case terminated on November 14, 2025, when both parties executed a joint stipulation of dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Dismissal with prejudice is a permanent resolution: VTINVA is barred from reasserting the same claims arising from USD971180S against Zhu in any future federal proceeding. Critically, the stipulation included a mutual waiver of costs and attorneys’ fees, suggesting neither side secured a financial concession from the other.
The 379-day duration — spanning filing through stipulated dismissal — is consistent with pre-trial resolution patterns seen in design patent disputes involving individual defendants, where litigation costs can quickly outweigh recovery prospects. The mutual cost waiver and counter-claim structure (Zhu filed a counter-claim) suggest the parties reached a negotiated resolution rather than one side capitulating unilaterally. The specific terms of any underlying commercial arrangement, if any, are not reflected in the public docket.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii): joint stipulation ends the case permanently
Under FRCP 41(a)(1)(A)(ii), parties may jointly stipulate to dismiss an action without a court order. When the stipulation specifies ‘with prejudice,’ the dismissal is a final adjudication on the merits — VTINVA cannot refile the same design patent claims against Zhu in federal court. Zhu’s counter-claim is similarly extinguished. This mechanism is frequently used when parties reach a private resolution and wish to close the docket cleanly.
Permanent bar on re-filingVTINVA forfeits the right to re-assert USD971180S against Zhu
Dismissal with prejudice means VTINVA permanently relinquishes its infringement claims against this specific defendant regarding USD971180S. No damages award or injunctive relief is recorded in the public docket. However, USD971180S itself remains valid and enforceable against other parties — VTINVA retains full rights to assert the design patent in future actions against different defendants. The mutual cost waiver suggests VTINVA did not achieve a clear litigation win.
Patent survives; claims against Zhu extinguishedZhu walks away with no recorded liability and counter-claim closed
Zhenzhen Zhu faces no recorded damages judgment, injunction, or royalty obligation from this action. The counter-claim Zhu filed against VTINVA is also dismissed with prejudice under the same stipulation. Both parties bearing their own fees is commercially significant for an individual defendant: it confirms Zhu is not required to pay VTINVA’s litigation costs, which would be a common outcome in a plaintiff-favourable settlement. The resolution is consistent with a mutual stand-down.
No liability; counter-claim also closedDesign patent enforcement against individual sellers: a common e-commerce battleground
Cases of this pattern — a branded consumer electronics plaintiff asserting a design patent against an individual defendant, followed by swift stipulated dismissal — are common in e-commerce enforcement contexts. They typically suggest early resolution via takedown compliance, licensing, or nuisance settlement. Companies operating in the remote control or consumer electronics accessory market should note that USD971180S remains active and enforceable, and VTINVA’s willingness to litigate signals ongoing enforcement intent against copycat products.

Official order — verbatim text
The stipulation is precise in its legal effect: dismissal ‘with prejudice’ under Rule 41(a)(1)(A)(ii) operates as a final adjudication, permanently barring VTINVA from reasserting the same design patent claims against Zhu. The inclusion of Zhu’s counter-claim in the dismissal — and the mutual fee waiver — indicates a bilateral negotiated resolution rather than a unilateral capitulation. No merits determination on infringement or validity was made by the court.
USD971180S — Ornamental Design for a Remote Control
USD971180S, filed as application US29/845876, is a U.S. design patent protecting the ornamental appearance of the VTINVA Remote Control. Design patents under 35 U.S.C. § 171 protect the visual, non-functional characteristics of a product — meaning the scope of protection is limited to the specific ornamental design as depicted in the patent drawings. Infringement is assessed under the ‘ordinary observer’ test: whether an ordinary purchaser, familiar with the prior art, would be deceived into thinking the accused product is the same as the patented design.
Design patents for consumer electronics accessories — particularly remote controls — are a growing enforcement tool for brands seeking to differentiate their products visually in crowded e-commerce markets. The relatively low cost of design patent prosecution compared to utility patents makes them attractive for product lines where ornamental differentiation is a key brand asset. USD971180S, still valid and unencumbered by this litigation outcome, represents an enforceable IP right that could be deployed against any market participant whose remote control design is deemed substantially similar by an ordinary observer.
Should you run an FTO against USD971180S before launching a remote control product?
Any company designing, importing, or distributing a remote control — particularly for consumer electronics or smart home devices sold via e-commerce channels — should evaluate design clearance against USD971180S. The ordinary observer test applied to design patents means that visual similarity, not functional identity, is the operative risk. Products with similar button layouts, housing profiles, or overall aesthetic to the VTINVA Remote Control design may fall within the scope of this patent’s claims.

What this case signals for the consumer electronics design patent landscape
Design patent enforcement in e-commerce markets is escalating. This case illustrates the pressure individual sellers face when a brand deploys litigation.
USD971180S is still live — third parties remain at infringement risk
The dismissal with prejudice resolves VTINVA’s claims only against Zhenzhen Zhu. Design patent USD971180S covering the VTINVA Remote Control remains valid and enforceable. Any party manufacturing, importing, or selling a product with a substantially similar ornamental design should conduct an FTO review before commercialising.
Mutual cost waivers are a signal — not a concession of weakness
The ‘each party bears its own fees’ structure in this stipulation is standard for negotiated walk-aways but does not indicate who had the stronger legal position. In design patent disputes, plaintiffs often accept this structure when the primary goal is market clearing rather than damages recovery — particularly against individual or small-volume defendants.
Sichuan v Zhenzhen — key questions answered
Dismissal with prejudice means VTINVA’s infringement claims against Zhenzhen Zhu are permanently extinguished. VTINVA cannot re-file the same claims arising from USD971180S against Zhu in any future federal proceeding. The dismissal was entered by joint stipulation under FRCP 41(a)(1)(A)(ii), with no merits determination by the court.
Yes. The dismissal resolves VTINVA’s claims only as against Zhenzhen Zhu. Design patent USD971180S — covering the ornamental design of the VTINVA Remote Control — remains valid and fully enforceable against any other third party. VTINVA retains all rights to assert it in future infringement actions.
The mutual cost waiver is standard in negotiated stipulated dismissals and does not indicate which party had the stronger legal position. It typically signals a bilateral resolution where neither side obtained a clear financial concession from the other — consistent with a commercial stand-down or confidential settlement rather than a contested adjudication.
Zhu’s counter-claim elevated the litigation stakes for VTINVA beyond a simple defence posture. Counter-claims — which may have included invalidity or non-infringement arguments — increase the plaintiff’s exposure and cost of continued litigation, and commonly serve as leverage toward a mutual dismissal outcome. The counter-claim was also dismissed with prejudice under the joint stipulation.
The Eastern District of Texas is a historically patent-holder-friendly venue with established local patent rules. Plaintiffs sometimes select EDTX to create procedural and geographic pressure on defendants, particularly individuals or small entities for whom defending in that district is costly. Public records do not disclose VTINVA’s specific venue rationale, but the choice is consistent with an enforcement-focused litigation strategy.
