Dyson Technology Ltd v. Schedule A Defendants — Battery Pack Design Patent Dismissed
Dyson Technology Limited brought a design patent infringement action in the Northern District of Illinois against anonymous online sellers identified on a Schedule A, asserting USD710299S covering a battery pack. The case closed voluntarily without prejudice just 61 days after filing — a timeline consistent with early resolution or parallel enforcement pressure.
Dyson’s Schedule A design patent action ends after 61 days
On 14 August 2025, Dyson Technology Limited — the UK-based consumer technology group and holder of design patent USD710299S — filed suit in the Northern District of Illinois against a set of unnamed online sellers grouped under the pseudonym ‘The Partnerships and Unincorporated Associations Identified on Schedule A.’ The asserted patent, filed as US29/464509, protects the ornamental design of a battery pack. Schedule A complaints are a well-established enforcement tactic in N.D. Illinois, commonly deployed against e-commerce sellers alleged to be infringing consumer product designs at scale.
The case closed on 14 October 2025 — exactly 61 days after filing — when Dyson filed a notice of voluntary dismissal without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i) specifically as to defendant ‘gadget_gift’ and the individuals and entities operating under that name. A dismissal without prejudice means Dyson has not surrendered its right to bring the same claims again: the patent remains asserted and enforceable, and Dyson faces no res judicata bar against refiling against gadget_gift or related parties.
A 61-day lifespan is notably short even for Schedule A cases, which often resolve quickly through default judgment or early settlement. The public record does not disclose whether a settlement, payment, or takedown agreement was reached — the dismissal notice is silent on terms. The specificity of the dismissal (naming gadget_gift alone) suggests this may have been one defendant among a broader Schedule A roster, with other defendants potentially subject to ongoing or separate proceedings. No fee award or costs ruling is recorded.
Filing to Voluntary dismissal in 61 days
61 days — well below the typical N.D. Illinois patent case median of 2+ years
Voluntarily dismissed without prejudice: what the ruling means for both parties
Rule 41(a)(1) dismissal: no merits ruling, case closes cleanly
A voluntary dismissal under Rule 41(a)(1)(A)(i) requires no court order and takes effect upon filing. Crucially, it carries no adjudication on the merits — the court made no finding on infringement, validity, or enforceability of USD710299S. Dyson retains full freedom to refile the same claims against gadget_gift in any competent court, subject only to any applicable statute of limitations.
No merits adjudicationWithout prejudice vs. with prejudice — what the record shows
The dismissal notice expressly states ‘without prejudice,’ which is legally significant. A with-prejudice dismissal would permanently bar Dyson from refiling against these defendants on the same patent claims. Without prejudice preserves Dyson’s enforcement options entirely. The public record does not disclose any settlement terms, payment, or takedown obligation — the basis for Dyson’s decision to dismiss remains commercially confidential.
Refiling rights preservedgadget_gift avoids judgment — but faces continued exposure
The named defendant, gadget_gift, secures no declaratory judgment of non-infringement and gains no finding that USD710299S is invalid or unenforceable. While the immediate litigation threat is removed, Dyson’s without-prejudice dismissal means gadget_gift cannot treat this case as a clean bill of health. Any continued sale of products that Dyson contends infringe the battery pack design could trigger refiling.
No invalidity finding securedUSD710299S remains a live enforcement tool for Dyson
Design patent USD710299S survives this proceeding with full enforceability intact. For other Schedule A sellers and e-commerce platforms offering battery packs with similar ornamental designs, this case signals that Dyson is actively monitoring and asserting this right. The 61-day resolution — without any validity challenge reaching the record — means the patent’s strength has not been publicly tested, preserving its deterrent value across the market.

Official order — verbatim text
The dismissal notice is narrow and precise: it names ‘gadget_gift and the Individuals and Entities Operating gadget_gift’ as the sole subject of the withdrawal, leaving open the possibility that other Schedule A defendants remain subject to separate proceedings. Filed under Rule 41(a)(1), the notice required no judicial approval and carries no court-endorsed findings. The phrase ‘the above captioned case may be terminated’ is procedural housekeeping — it confers no rights on the defendant and constitutes no concession by Dyson on the merits of the infringement claim.
USD710299S — Ornamental design for a battery pack
USD710299S, filed as application US29/464509, is a US design patent protecting the ornamental appearance of a battery pack — the visual and aesthetic elements of the product form, not its functional attributes. Design patents under 35 U.S.C. § 171 grant protection for the novel, ornamental characteristics of a manufactured article. The scope of protection is defined by the drawings in the patent, making claim construction in design patent cases highly visual and context-dependent. Dyson’s battery packs are central to its cordless vacuum and appliance product lines.
For e-commerce sellers and OEM manufacturers operating in the battery pack and cordless appliance accessory space, USD710299S represents a concrete enforcement risk. Dyson has demonstrated willingness to assert this design right aggressively through Schedule A actions in N.D. Illinois — a venue known for its streamlined handling of multi-defendant IP cases. Competitors developing visually similar battery pack form factors should treat this patent as an active clearance concern, particularly given that the without-prejudice dismissal leaves the patent’s enforceability entirely intact.
Should you run an FTO against USD710299S?
Any company designing, importing, or selling battery packs — particularly those intended as accessories or replacements for cordless consumer appliances — should assess whether their product’s ornamental design could be colourably similar to USD710299S. Dyson’s active Schedule A enforcement in N.D. Illinois means exposure is not theoretical. E-commerce sellers, OEMs, and product development teams working on battery pack form factors should not rely on this case’s dismissal as clearance.

What this case signals for the consumer electronics IP landscape
Dyson’s rapid Schedule A filing and withdrawal patterns reveal a disciplined, volume-based design patent enforcement strategy worth tracking.
Schedule A filings are pressure tools — not always intended for trial
Dyson’s 61-day filing-to-dismissal cycle is consistent with a strategy of using N.D. Illinois Schedule A complaints to secure early injunctive relief, TRO orders, or asset freezes, then dismiss once a defendant complies or a commercial resolution is reached. IP teams competing in battery accessories and consumer electronics should map Dyson’s Schedule A docket comprehensively.
Without-prejudice exits preserve Dyson’s enforcement optionality
Because no merits ruling was entered, USD710299S is as enforceable today as it was at filing. Sellers and manufacturers of battery pack products should not interpret this dismissal as a safe harbour. Dyson retains the right to refile against gadget_gift or pursue related defendants under the same or related design patents without any prior adjudication as a barrier.
Limited v Partnerships — key questions answered
The case was voluntarily dismissed without prejudice by Dyson Technology Limited on 14 October 2025, 61 days after filing. The dismissal was filed under Rule 41(a)(1) specifically as to defendant gadget_gift. No merits ruling was entered, and USD710299S remains fully enforceable.
Dyson asserted design patent USD710299S (application number US29/464509), which protects the ornamental design of a battery pack. Design patents under 35 U.S.C. § 171 cover the visual appearance of a product, not its functional features. The scope is defined by the patent’s drawings.
A without-prejudice dismissal means Dyson has not waived its right to refile the same infringement claims against gadget_gift or related parties. The defendant receives no declaration of non-infringement and no finding of invalidity. The patent remains fully enforceable, and Dyson faces no legal bar to initiating new proceedings.
N.D. Illinois is a preferred venue for Schedule A actions because its local rules facilitate expedited proceedings against anonymous or pseudonymous online sellers. Courts in this district routinely grant temporary restraining orders and asset freezes early in the case, making it an effective forum for enforcing design patents against e-commerce infringers at scale.
No. Because the case was dismissed without prejudice and without any merits adjudication, USD710299S remains valid and enforceable as issued. No court finding of invalidity, non-infringement, or unenforceability was entered. Manufacturers and sellers of battery pack products should continue to treat this design patent as an active enforcement risk.
