Noco Co. v. Winplus: Jump Starter Patent Dispute Stayed After 79 Days
Noco Co. asserted three US patents covering portable vehicle battery jump starters against Winplus Company, Winplus NA LLC, and ADC Solutions Auto LLC in California's Central District. The court granted the defendants' unopposed motion to stay just 79 days after filing, halting proceedings before any merits ruling.
Noco's Jump Starter Patent Claims Halted by Unopposed Stay
On 14 February 2023, Noco Co. filed an infringement action in the Central District of California against Winplus Company, Winplus NA LLC, and ADC Solutions Auto LLC. Noco asserted three US patents — US11254213B2, US11447023B2, and US10981452B2 — covering portable vehicle battery jump starting apparatus technology, including designs with battery cell equalization circuits, safety protection features, and jumper cable devices.
The recorded basis of termination is 'Case Stayed.' The docket order states that the court granted the defendants' unopposed motion to stay, finding good cause shown for the requested relief. The motion was brought by Winplus North America Inc., Winplus NA LLC, and ADC Solutions Auto LLC, and was not opposed by Noco at the time of the ruling.

US11254213B2, US11447023B2 & US10981452B2 — Portable Jump Starter Technology
Any company designing, manufacturing, importing, or distributing portable vehicle battery jump starters — particularly products featuring battery cell equalization circuits, safety protection electronics, or integrated jumper cable devices — should assess freedom-to-operate against these three Noco patents. The stay preserves Noco's ability to resume enforcement at any time, meaning commercial exposure remains live.
Official order — verbatim text
The court's order granting the stay records that good cause was shown and that the motion was unopposed by Noco. No merits ruling was issued; the stay suspends all proceedings without adjudicating infringement, validity, or damages on any of the three asserted patents.

R&D signals in portable vehicle jump starter technology
Forward-looking patent and innovation intelligence derived from Noco's three-patent assertion against Winplus in the portable jump starter space.
Noco's jump starter filing activity signals continued IP build-out
With three patents filed in a coordinated 2019–2020 window and now asserted in litigation, Noco's portfolio suggests an active IP development strategy around next-generation jump starter architectures. Monitoring Noco's continuation filings and pending applications in this family will indicate whether further enforcement risk is expanding across new product variants.
Active portfolio expansionBattery cell equalization in jump starters: a contested innovation frontier
Battery cell equalization circuitry — a core claim element in US11254213B2 — is an active area of development as jump starter manufacturers integrate lithium-ion multi-cell architectures. Tracking filing trends around equalization circuit patents reveals which competitors are investing in this space and where design-around opportunities may exist.
Active filing trendWinplus and ADC Solutions' patent position in portable power accessories
Assessing Winplus Company's and ADC Solutions Auto LLC's own patent holdings and licensing arrangements in the portable jump starter and automotive accessory space can reveal whether they hold defensive IP or are primarily reliant on freedom-to-operate analyses. Their response posture in this case — seeking a stay rather than challenging on the merits — may reflect IP position or parallel proceedings strategy.
Defensive IP postureSafety protection and cable interface design: adjacencies beyond Noco's claims
Noco's claim scope around safety protection circuitry and jumper cable device design leaves adjacent technical territory — such as wireless or inductive transfer interfaces, AI-driven fault detection, and modular multi-chemistry support — potentially unclaimed. R&D teams can use claim mapping to identify white-space filing opportunities in these next-generation jump starter architectures.

What this stay signals for the portable jump starter IP landscape
An unopposed stay this early in litigation warrants close attention from anyone competing in portable vehicle power products.
Unopposed stays signal parallel proceedings — monitor USPTO and ITC activity
When a defendant seeks and obtains an unopposed stay within 79 days of filing, it typically suggests a parallel proceeding — such as an IPR petition or ITC investigation — is underway or anticipated. Competitors and licensees holding positions in portable jump starter technology should track USPTO PTAB filings against Noco's three asserted patents closely.
Three-patent assertion signals a broad Noco enforcement posture
Asserting three patents across jump starter circuitry, safety protection, and cable device design in a single action suggests Noco is pursuing layered IP protection. Product teams developing portable battery jump starters should conduct FTO analysis across Noco's full portfolio, not only the three asserted patents.
Noco v Winplus — key questions answered
The case was stayed by the Central District of California on 4 May 2023. The court granted the defendants' unopposed motion to stay, finding good cause shown. No merits ruling on infringement, validity, or damages has been issued. The case remains suspended pending further court order.
Noco asserted three US patents: US11254213B2 (application US16/461562), US11447023B2 (application US16/450422), and US10981452B2 (application US16/587624). All three cover portable vehicle battery jump starting apparatus technology, including battery cell equalization circuits, safety protection systems, and jumper cable device configurations.
The court's order states that good cause was shown for the stay and that the motion was unopposed by Noco. The specific grounds for the stay are not detailed in the available docket record. Unopposed early stays in patent cases are often associated with parallel USPTO proceedings such as inter partes review petitions, though no such proceeding is confirmed in the available record.
Three defendant entities were named: Winplus Company, Winplus NA LLC, and ADC Solutions Auto LLC. Naming multiple related corporate entities and a distribution-level company in a single infringement action is consistent with a strategy to capture liability across the full manufacturing and sales chain, though the specific relationships between these entities are not detailed in the available record.
The case record identifies two product categories: a portable or handheld vehicle battery jump starting apparatus with a battery cell equalization circuit, and a portable vehicle battery jump start apparatus with safety protection and a jumper cable device. Specific model names or product identifiers are not disclosed in the available public record.
