Shenzhenshibairihongmao v. Novoluto GmbH: Rose Suction Device Patent Terminated in 1 Day
A Chinese consumer-goods company asserted US9763851B2 — covering suction devices shaped as flowers or roses — against German firm Novoluto GmbH in the Virginia Eastern District Court. The case was closed within a single day of filing, suggesting a procedural termination before any substantive proceedings commenced.
A one-day patent filing: procedural termination in suction-device IP dispute
On 9 October 2025, Shenzhenshibairihongmao — a Shenzhen-based trading company — filed an infringement action (Case No. 1:25-cv-01730) in the Virginia Eastern District Court against Novoluto GmbH, a German intimate-wellness technology firm. The asserted patent, US9763851B2 (application no. US15/023471), covers suction device technology embodied in a flower- or rose-shaped product — a consumer category that has grown substantially in recent years.
The case was terminated on 10 October 2025 — one day after filing. The public record designates the basis of termination simply as ‘Case Terminated,’ without specifying whether this reflects a voluntary dismissal, a procedural defect, a filing error, or a court-initiated administrative closure. No defendant agents or defendant law firm are recorded, suggesting Novoluto GmbH had not yet appeared before termination occurred.
A one-day lifespan is highly atypical for district court patent litigation and most likely signals a clerical or jurisdictional issue with the original filing rather than a substantive resolution. The absence of a judge assignment and defendant representation on the docket is consistent with the case having been closed before service was effected. What, if anything, the plaintiff intends next — including refiling in a different venue — remains unknown from the public record.

Case terminated in one day: what the public record reveals
Administrative termination: no merits ruling recorded
A ‘Case Terminated’ basis without further qualification typically indicates an administrative or procedural closure rather than a decision on the merits. This can arise from filing deficiencies, jurisdictional problems, failure to pay filing fees, or a court clerk’s administrative action. No judge was assigned, which is consistent with the case ending before normal docketing processes completed.
No merits adjudicationTermination leaves the dispute legally unresolved
Because the public record does not specify whether the termination was with or without prejudice, the plaintiff’s ability to refile the same claims cannot be confirmed or ruled out from available data. A purely administrative closure would generally not bar refiling, but the specific circumstances here are ambiguous. Both parties should treat the underlying patent dispute as potentially ongoing until clarified.
Refiling status unclearNovoluto GmbH: no appearance required before closure
No defendant agents or law firm are recorded on the docket, suggesting Novoluto GmbH was never formally served or did not enter an appearance before the case closed. This means no responsive pleading, invalidity argument, or counterclaim was filed. The infringement allegation against Novoluto’s products has therefore not been tested or adjudicated in this proceeding.
No defendant appearanceRose-device patent remains in play for the sector
US9763851B2 covering suction devices in flower or rose form factors remains an active enforcement asset. The abrupt termination of this case does not diminish the patent’s validity or enforceability. Competitors and distributors in the intimate-wellness and personal-care device market should monitor future filings by the plaintiff against Novoluto or other parties in this product category.

Official order — verbatim text
The verdict entry ‘Case terminated’ without elaboration on basis offers limited analytical purchase. It indicates the court did not reach any infringement, validity, or claim-construction question. The absence of a judge assignment and defendant representation suggests the termination occurred at or before the docketing stage. This phrasing is procedurally distinct from a dismissal with or without prejudice and does not, on its face, constitute a ruling that would bind either party on the merits of US9763851B2.
US9763851B2 — suction device in flower/rose form factor
US9763851B2 (application US15/023471) protects a suction-based device designed in the form of a flower or rose. The patent sits within the broader intimate-wellness and personal-care technology space, where tactile form factors have become a significant product differentiator. The application’s filing lineage through US15/023471 suggests international prosecution origins, consistent with the Shenzhen-based plaintiff’s manufacturing profile.
The commercial relevance of this patent is substantial. Rose- and flower-shaped suction devices have become a high-volume consumer category globally, with significant import volume into the US market. A patent covering this form factor — if broadly construed — could capture a wide range of competing products. For companies distributing or manufacturing in this space, the enforceability and claim scope of US9763851B2 warrants careful attention, especially given the plaintiff’s apparent willingness to litigate in US federal courts.
Should you run an FTO against US9763851B2?
Any company manufacturing, importing, or distributing suction devices in rose or flower form factors for the US market should consider a freedom-to-operate review against US9763851B2. The plaintiff’s filing — however brief — signals active enforcement intent. OEMs, white-label suppliers, and e-commerce retailers sourcing from Shenzhen-based manufacturers are particularly exposed if their product designs overlap with the patent’s claims.

What this case signals for the intimate-wellness device IP landscape
Even a one-day filing creates a litigation record that patent holders can build on — and that competitors must monitor.
One-day cases still create prior litigation history for enforcement signals
Even a procedurally aborted filing establishes that the patent holder is actively pursuing enforcement. Product companies in the suction-device and intimate-wellness space should treat this as an early indicator of a broader enforcement strategy, particularly given the plaintiff’s apparent product-manufacturing base in Shenzhen.
Venue choice matters: Virginia Eastern is a high-volume patent docket
Filing in the Virginia Eastern District Court — home to the ‘rocket docket’ — suggests the plaintiff or counsel anticipated an aggressive litigation timeline. If refiled, defendants should prepare for rapid scheduling. The one-day termination may reflect a venue mismatch or technical filing issue rather than strategic withdrawal.
Shenzhenshibairihongmaoyiyouxiangongsi v Novoluto — key questions answered
The case was filed on 9 October 2025 and terminated the following day, 10 October 2025. The basis of termination is recorded only as ‘Case Terminated’ with no further explanation, and no judge was assigned. No substantive proceedings or merits rulings occurred.
US9763851B2 covers a suction device designed in the form of a flower or rose, falling within the intimate-wellness and personal-care technology category. The product involved in the litigation is described as a suction device in the shape of a flower or rose. The patent was asserted via application number US15/023471.
The public record does not specify the reason. A one-day termination without a judge assignment or defendant appearance typically suggests a procedural or administrative issue — such as a filing defect, jurisdictional problem, or clerical error — rather than a voluntary strategic withdrawal or settlement.
The public record does not state whether the termination was with or without prejudice, making refiling eligibility ambiguous from available data. A purely administrative closure would generally not preclude refiling. Both parties and market observers should monitor for subsequent filings by the plaintiff in this or other venues.
Yes. The one-day termination did not involve any validity ruling, claim construction, or finding of non-infringement. US9763851B2 remains a granted US patent with full enforceability. The abrupt case closure does not affect the patent’s legal status, and the plaintiff retains the right to assert it in future proceedings subject to any applicable procedural constraints.
