Bright Head LLC v. Schedule A Defendants: Federal Circuit Appeal Dismissed
Bright Head LLC brought a patent infringement action asserting US10928052B2, covering a hands-free headlamp system, against a broad ‘Schedule A’ defendant class. The Federal Circuit dismissed the appeal in just 98 days — not on the merits, but for failure to prosecute: no counsel appeared and no brief was filed.
Procedural collapse: headlamp patent appeal never reaches the merits
Bright Head LLC filed a patent infringement action asserting US10928052B2, a granted U.S. patent covering a hands-free headlamp system, against a large and unnamed group of defendants identified only on Schedule A — a format commonly used in mass e-commerce enforcement actions. The appeal was docketed at the Court of Appeals for the Federal Circuit on 24 September 2025 under case number 25-2142, with Nicholas S. Lee listed as plaintiff’s agent.
The Federal Circuit dismissed the appeal on 31 December 2025 — 98 days after filing — on purely procedural grounds. The court’s order records two failures: no attorney admitted to the Federal Circuit bar filed the required Entry of Appearance form, and no opening brief was filed within the time permitted under Federal Circuit Rule 31(a). The court ordered the notice of appeal dismissed for failure to prosecute in accordance with the rules. No merits adjudication of the underlying infringement claims took place.
The 98-day resolution is shorter than a typical Federal Circuit merits timeline, but it reflects administrative closure rather than swift adjudication. The public record does not disclose what occurred at the district court level prior to this appeal, why no qualified counsel appeared, or whether Bright Head LLC intends to refile or pursue alternative enforcement routes. The absence of a merits ruling leaves the validity and enforceability of US10928052B2 unresolved by this court.
Filing to Appeal Dismissed in 98 days
98 days — faster than typical Federal Circuit merits disposition, resolved procedurally
Appeal dismissed for failure to prosecute: what this means for both sides
Dismissed for failure to prosecute — no merits ruling
The Federal Circuit dismissed the appeal because Bright Head LLC failed two threshold procedural requirements: no attorney admitted to the Federal Circuit bar entered an appearance, and no brief was filed under Fed. Cir. R. 31(a). A dismissal for failure to prosecute is purely procedural — the court expressed no view on the validity or infringement of US10928052B2. The underlying patent rights remain intact but unvalidated at the appellate level.
No merits adjudicationBright Head LLC loses its appellate path without a ruling
Bright Head LLC forfeits the appeal entirely without any appellate court review of its infringement claims. The dismissal does not bar refiling a new action in district court on the same patent, but any district-level judgment that may have been appealed now stands unchallenged. The failure to secure qualified Federal Circuit counsel suggests resource or strategic constraints that may affect future enforcement of US10928052B2.
Appeal forfeited procedurallySchedule A defendants escape appellate review by default
The unnamed Schedule A defendants benefit from the dismissal without needing to file any brief or incur appellate litigation costs. Whatever district-level outcome preceded this appeal is preserved in their favour to the extent the appeal sought to disturb it. However, because no merits ruling was issued, the defendants cannot point to this dismissal as a precedent invalidating or limiting US10928052B2.
No appellate exposure incurredHeadlamp patent remains unresolved — enforcement uncertainty persists
US10928052B2 exits this appeal neither validated nor invalidated. Competitors and e-commerce sellers in the wearable lighting space cannot rely on this dismissal as clearing the patent. Bright Head LLC retains the right to assert the patent in fresh district court proceedings. The Schedule A enforcement model — targeting multiple unnamed online sellers — continues to be a live risk for marketplace vendors of hands-free headlamp products.

Official order — verbatim text
The Federal Circuit’s order is a procedural termination, not a merits ruling. The court’s language — ‘failure to prosecute in accordance with the rules’ — reflects the application of Federal Circuit Rule 31(a) and the court’s Entry of Appearance requirements. No standard of review of the underlying infringement issues was engaged. The order leaves the district court record undisturbed and US10928052B2 neither validated nor invalidated at the appellate level. Both parties’ substantive positions on infringement remain legally open.
US10928052B2 — Hands-free headlamp system
US10928052B2 is a granted U.S. utility patent filed under application number US15/681269, covering a hands-free headlamp system. The patent sits in the wearable lighting technology domain, protecting design or functional elements of a headlamp apparatus intended to operate without manual handling. As a granted patent, it carries a presumption of validity under 35 U.S.C. § 282. The application date provides a priority date relevant to assessing prior art challenges.
In the context of the rapidly growing wearable and outdoor lighting accessories market, US10928052B2 represents an enforcement asset being actively deployed against e-commerce sellers through the Schedule A model. The patent’s scope — covering a hands-free headlamp system — potentially captures a broad range of products sold on platforms such as Amazon and Alibaba. Competitors developing or sourcing wearable headlamp products should assess whether their designs fall within the claim scope before entering or expanding in this category.
Should you run an FTO against US10928052B2?
Any company designing, manufacturing, importing, or selling hands-free headlamp products in the U.S. market should treat US10928052B2 as an active enforcement risk. Bright Head LLC has demonstrated willingness to pursue litigation through both district court and appellate stages. The Schedule A enforcement model means re-filing against new groups of online sellers is low-cost and rapid. A freedom-to-operate analysis is advisable before product launch, sourcing, or platform listing.

What this case signals for the wearable lighting IP enforcement landscape
A procedural collapse at the Federal Circuit leaves US10928052B2 in legal limbo — and raises questions about the Schedule A enforcement model.
Federal Circuit bar admission is a hard requirement — no exceptions
The Federal Circuit enforces its own admission and appearance rules strictly. Failure to file an Entry of Appearance by a bar-admitted attorney is an automatic ground for dismissal. Parties pursuing appeals from district-level patent rulings must engage counsel specifically admitted to the Federal Circuit bar, distinct from general patent litigation counsel.
Schedule A enforcement actions carry procedural fragility at the appellate stage
Mass Schedule A infringement suits against unnamed e-commerce defendants are resource-intensive at scale. When such cases reach the appellate level, the administrative demands intensify. This dismissal is consistent with a pattern where smaller IP enforcement entities struggle to sustain proceedings through the appellate phase without dedicated appellate counsel.
BRIGHT v INDIVIDUALS — key questions answered
The Federal Circuit dismissed case 25-2142 because Bright Head LLC failed to file a required Entry of Appearance by a bar-admitted attorney and failed to file its opening brief under Federal Circuit Rule 31(a) within the permitted time. The court ordered the notice of appeal dismissed for failure to prosecute. No merits ruling on the underlying patent infringement claims was issued.
No. The dismissal was purely procedural and expressed no opinion on the validity or enforceability of US10928052B2. The patent retains its presumption of validity under 35 U.S.C. § 282. Bright Head LLC remains free to assert the patent in future district court proceedings.
The Schedule A model is a litigation format where a patent plaintiff sues a large group of unnamed defendants — typically e-commerce sellers — identified only on a confidential schedule. It is commonly used against online marketplace vendors selling allegedly infringing products. Courts have varied in their treatment of this format regarding joinder and service requirements.
Federal Circuit Rule 31(a) sets the deadline for filing the appellant’s opening brief. Failure to file within the specified time — without obtaining an extension — is grounds for dismissal of the appeal for failure to prosecute, as applied in case 25-2142 against Bright Head LLC.
A dismissal for failure to prosecute at the appellate level does not bar the plaintiff from filing a new district court action on the same patent. Bright Head LLC could potentially bring fresh infringement proceedings asserting US10928052B2 against new or existing defendants, subject to applicable statutes of limitations and any district court orders from prior proceedings.
