Socket Solutions v. Top Greener: Outlet Cover Patent Dismissed Without Prejudice
Socket Solutions, LLC filed a patent infringement action against Top Greener, LLC in the Central District of California, asserting US9509080B1 directed to electrical wall outlet covers sold via topgreener.com. The case closed just 61 days after filing when Socket Solutions voluntarily dismissed without prejudice — leaving the door open for re-filing.
A 61-day outlet patent dispute closed before discovery began
On December 21, 2023, Socket Solutions, LLC filed a patent infringement action against Top Greener, LLC in the Central District of California, asserting US9509080B1, a patent directed to electrical wall outlet cover technology. Top Greener sells electrical products including outlet covers through its topgreener.com website, which was identified as a product and sales channel at issue. The case was initially assigned to Judge Cormac J. Carney before being administratively transferred to Judge John W. Holcomb in January 2024.
On February 19, 2024 — just 61 days after filing — Socket Solutions filed a Notice of Voluntary Dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii), alongside a Stipulation to Dismiss. Critically, the dismissal was filed without prejudice, meaning Socket Solutions retains the legal right to bring the same claims against Top Greener in a future action. No merits ruling, claim construction order, or damages determination was issued.
The speed of resolution — before any substantive motion practice or scheduling conference could take root — suggests the parties may have reached a private arrangement, or that Socket Solutions chose to withdraw strategically. The public record is silent on whether any licensing agreement, settlement payment, or design-around commitment was reached. Because the dismissal is without prejudice, the enforceability of US9509080B1 against Top Greener remains unresolved and could be revisited.

Dismissed without prejudice: what the voluntary exit means for both parties
Rule 41(a)(1)(A)(ii) — stipulated voluntary dismissal
Under FRCP 41(a)(1)(A)(ii), a plaintiff may voluntarily dismiss a case without a court order by filing a stipulation signed by all parties. This mechanism requires defendant consent, distinguishing it from a unilateral withdrawal. The dismissal is without prejudice here, meaning Socket Solutions is not barred from re-asserting the same patent claims in a new action. No substantive ruling was made on infringement, validity, or damages.
No merits adjudicationSocket Solutions exits — but retains full right to refile
A dismissal without prejudice preserves Socket Solutions’ right to assert US9509080B1 against Top Greener in a future action, subject to applicable statutes of limitations. The plaintiff gave up no substantive ground. However, a second voluntary dismissal against the same defendant would likely operate as an adjudication on the merits under FRCP 41(a)(1)(B) — the ‘two dismissal rule’ — raising the stakes of any future filing significantly.
Refile right preservedTop Greener avoids a ruling — but faces residual patent risk
Top Greener obtained no declaratory judgment of non-infringement or invalidity. US9509080B1 remains in force, and Top Greener’s outlet cover products and topgreener.com sales channel remain potentially exposed to a future infringement action. Without a ruling, Top Greener cannot invoke res judicata or issue preclusion as a shield. Any product design changes or licensing discussions that may have occurred are not reflected in the public record.
No immunity from re-filingOutlet cover manufacturers face unresolved IP exposure
Because the case resolved without any claim construction or validity assessment, US9509080B1 retains its full presumption of validity. Competitors in the electrical wall outlet and socket cover space — particularly those selling through e-commerce channels — should treat this patent as an active enforcement risk. The speed of dismissal and the without-prejudice designation are consistent with a pre-litigation licensing dynamic that could extend to other market participants.

Official order — verbatim text
The record reflects a stipulated voluntary dismissal under FRCP 41(a)(1)(A)(ii) with an explicit without-prejudice designation, filed by Socket Solutions on February 19, 2024. This procedural exit carries no finding on infringement or validity of US9509080B1. The joint stipulation suggests Top Greener’s acquiescence, though the terms of any collateral agreement remain undisclosed. The patent’s enforceability is entirely intact, and the without-prejudice designation means Socket Solutions may initiate a new action asserting identical claims.
US9509080B1 — electrical wall outlet cover technology
US9509080B1 is a granted U.S. utility patent asserting rights in electrical wall outlet cover technology, filed under application number US15/099559. The patent relates to the design and functional integration of outlet cover assemblies — a product category spanning residential, commercial, and consumer electronics accessory markets. As a B1 grant, the patent issued without any re-examination amendments on record at the time of grant, carrying the full statutory presumption of validity under 35 U.S.C. § 282.
Outlet cover and socket technology occupies a commercially dense space where incremental design innovations can attract meaningful IP disputes. Socket Solutions’ willingness to file federal litigation — even briefly — signals that it treats US9509080B1 as an enforcement-grade asset rather than a defensive portfolio piece. For any manufacturer producing outlet covers, faceplates, or integrated socket assemblies, this patent warrants active monitoring, particularly given the unresolved claim scope following dismissal without any court construction.
Should you run an FTO analysis against US9509080B1?
Any company designing, manufacturing, or distributing electrical wall outlet covers — particularly those with integrated or flush-mount socket elements — should assess their freedom to operate against US9509080B1. This is especially relevant for brands selling through e-commerce channels, given that Top Greener’s website was specifically cited as a sales channel of concern. The absence of a claim construction ruling means the patent’s enforceable scope has never been publicly tested, making independent FTO analysis essential before product launch or continued distribution.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the independent claims of US9509080B1, identify prior art that may constrain the patent’s scope, and flag related continuation or family patents in Socket Solutions’ portfolio.

What this case signals for the electrical socket IP landscape
A rapid voluntary dismissal without prejudice in outlet cover patent litigation typically signals unresolved commercial dynamics worth monitoring.
Without-prejudice exit is a classic demand-letter precursor to licensing
Cases resolved this quickly — before any substantive motion or scheduling order — are frequently consistent with a licensing approach rather than full-scale litigation. Socket Solutions may be using litigation filings as a structured licensing outreach. Competitors in the outlet cover and socket technology space should assess their exposure to US9509080B1 before receiving a demand letter.
Top Greener’s e-commerce channel was specifically cited — a signal to online sellers
The explicit reference to topgreener.com in the complaint suggests the patent holder is monitoring online sales channels to identify infringement. Other electrical accessory brands selling outlet covers via e-commerce marketplaces or direct-to-consumer sites should review their product lines against US9509080B1’s claim scope, particularly if they offer flush-mount or cover-integrated socket products.
Socket v Top — key questions answered
Socket Solutions, LLC filed a patent infringement action against Top Greener, LLC in the Central District of California on December 21, 2023, asserting US9509080B1 relating to electrical wall outlet covers. The case was voluntarily dismissed without prejudice on February 19, 2024 — just 61 days after filing — with no merits ruling issued.
A dismissal without prejudice means Socket Solutions retains the right to refile the same patent infringement claims against Top Greener in the future. Top Greener received no court ruling establishing non-infringement or invalidity of US9509080B1, leaving the patent’s enforceability against its products unresolved. A second voluntary dismissal against the same defendant, however, would likely operate as a merits adjudication under FRCP 41(a)(1)(B).
US9509080B1 is a granted U.S. utility patent covering electrical wall outlet cover technology, filed under application number US15/099559. It relates to the design and functional construction of outlet cover assemblies. As a B1 grant, it issued without post-grant amendment and carries the full presumption of validity. Its specific claim scope was never construed by a court in this litigation.
The transfer from Judge Cormac J. Carney to Judge John W. Holcomb was an administrative reassignment pursuant to the Central District of California’s General Order governing case assignment, not a substantive ruling. The case number was updated to reflect Judge Holcomb’s initials: 8:23-cv-02439-JWH-(KESx). This type of intra-district transfer is routine and carries no implications for the merits of the underlying patent dispute.
The dismissal without prejudice has no preclusive effect on third parties. US9509080B1 remains valid and enforceable, and Socket Solutions may pursue infringement claims against other outlet cover manufacturers independently of this case. The explicit mention of topgreener.com as a sales channel suggests the patent holder is actively monitoring e-commerce distribution, which is relevant for any brand selling competing products online.
