Inhale v. Gravitron: Federal Circuit Dismisses Appeal for Lack of Jurisdiction
Inhale, Inc. brought an infringement appeal against Gravitron, LLC over US8393563B2, covering a handheld tobacco grinder with windows. The Federal Circuit dismissed the appeal for lack of jurisdiction in just 138 days, leaving the underlying district court case open to further proceedings and offering Inhale a narrow reinstatement window of 60 days.
Jurisdictional dismissal halts Inhale’s Federal Circuit appeal over grinder patent
Inhale, Inc. filed this appeal at the Court of Appeals for the Federal Circuit on 10 January 2025, targeting Gravitron, LLC for alleged infringement of US8393563B2, a patent covering a handheld tobacco grinder featuring windows. The appeal arose from an underlying infringement action, with Inhale represented by Strategic Legal Counseling and Gravitron by Winstead PC. The case was docketed as No. 25-1259 in the District of Columbia circuit region.
The Federal Circuit closed the case on 28 May 2025 — just 138 days after filing — by granting Gravitron’s motion to dismiss. The court found it lacked jurisdiction to hear the appeal, a threshold determination that ends the appellate proceeding without any ruling on the underlying patent infringement merits. Critically, the order preserves a reinstatement pathway: if Inhale appeals from an appealable final judgment in the underlying case within 60 days, the appeal may be reinstated under the same docket number without an additional filing fee.
The speed of resolution — under five months — is consistent with a pure jurisdictional dismissal, which requires no substantive briefing on the merits. The public record does not disclose the precise jurisdictional defect the court identified, though the absence of a final judgment in the underlying case is the most common basis for such dismissals at the Federal Circuit. Whether Inhale will obtain and appeal a final judgment within the 60-day window remains unknown from the available record.
Filing to Appeal Dismissed in 138 days
138-day appellate proceeding — resolved faster than typical Federal Circuit merits appeals
Appeal dismissed for lack of jurisdiction: what the order means for both parties
Jurisdictional dismissal ends appeal without merits review
A dismissal for lack of jurisdiction means the Federal Circuit declined to examine whether the underlying infringement ruling was correct. The court’s authority to hear an appeal generally requires a final, appealable judgment below. Where that predicate is absent, the appellate proceeding cannot proceed regardless of the substantive strength of either party’s position. This is a procedural terminus, not a vindication or defeat on the patent claims.
No merits adjudicationInhale retains a narrow 60-day reinstatement window
Inhale is not permanently barred from Federal Circuit review. The order expressly permits reinstatement under docket No. 25-1259 — without a new filing fee — if Inhale appeals from an appealable final judgment in the underlying case within 60 days of this order. This effectively pauses, rather than ends, Inhale’s appellate strategy, provided the district court proceedings advance to a final judgment promptly.
Reinstatement possibleGravitron escapes Federal Circuit review for now — but underlying risk persists
Gravitron successfully moved to dismiss the appeal, and each party bears its own costs — a neutral cost outcome. However, Gravitron obtains no merits ruling in its favour. The infringement allegations under US8393563B2 remain live in the underlying case. If Inhale secures and appeals a final judgment within the reinstatement window, Gravitron will face renewed appellate exposure.
Underlying case still liveJurisdictional uncertainty prolongs risk for tobacco accessories market
For competitors and licensees operating in the handheld grinder segment, the unresolved infringement question under US8393563B2 sustains commercial uncertainty. No court has ruled on validity or infringement, meaning the patent retains its presumption of validity. Companies manufacturing or selling similar windowed tobacco grinders should monitor whether Inhale pursues reinstatement and the eventual district court outcome closely.

Official order — verbatim text
The Federal Circuit’s order is unambiguous in its procedural character: the motion to dismiss is granted solely for lack of jurisdiction, with no assessment of infringement or validity under US8393563B2. The reinstatement clause is significant — it is not a final disposition of Inhale’s rights, but a conditional preservation of appellate access contingent on the underlying proceedings maturing to a final judgment. The own-costs ruling reflects standard practice in jurisdictional dismissals where neither party bears responsibility for the procedural defect in the usual adversarial sense.
US8393563B2 — Handheld tobacco grinder with windows
US8393563B2, filed under application number US12/980330, protects a handheld tobacco grinder incorporating windows — transparent viewing apertures that allow users to observe the grinding chamber contents. This is a mechanical consumer device patent in the tobacco accessories segment. The patent’s design and functional combination of grinding mechanism and windowed housing represents a specific product differentiation feature in a competitive consumer market.
The patent’s strategic relevance lies in the tobacco grinder accessories market, where product differentiation through design features carries commercial value. Competitors offering similar windowed grinder designs risk infringement exposure under this patent’s claims, which remain judicially untested on the merits following the Federal Circuit’s jurisdictional dismissal. For sector participants, the patent retains full presumptive validity, making it a meaningful consideration in product design, procurement decisions, and licensing strategy across the handheld grinder category.
Should you run an FTO against US8393563B2?
Any company designing, manufacturing, importing, or distributing handheld tobacco grinders — particularly models featuring transparent windows or viewing apertures — should evaluate freedom-to-operate against US8393563B2. The Federal Circuit’s dismissal for lack of jurisdiction leaves the patent’s claims entirely untested, meaning no narrowing or invalidity finding exists to limit its enforceability. This is especially relevant for brands competing directly in the premium or design-focused grinder segment.

What this case signals for the tobacco accessories IP landscape
A procedural dismissal without merits keeps US8393563B2 fully enforceable — sector players cannot take comfort from this outcome.
Jurisdictional dismissals reset the clock — not the risk
This Federal Circuit dismissal does not extinguish the patent or the infringement claim. US8393563B2 remains in force. Competitors in the handheld grinder space should treat this as a pause in proceedings, not a safe harbour. Monitor the 60-day reinstatement window and the underlying district court docket carefully.
Own-costs order signals neither party held a decisive advantage
The court’s decision that each party bears its own costs is consistent with a purely procedural outcome where fault lies with an unripe appeal rather than bad-faith conduct. This symmetry suggests neither party should read fee exposure into the dismissal — but it also withholds the deterrent signal a fee award might have sent.
Inhale v Gravitron — key questions answered
The Court of Appeals for the Federal Circuit dismissed case No. 25-1259 for lack of jurisdiction. The order does not specify the precise defect on the public record, but the absence of a final appealable judgment in the underlying district court case is the most common basis for such dismissals. No merits ruling on US8393563B2 infringement was issued.
Yes, subject to conditions. The Federal Circuit’s order expressly provides for reinstatement under docket No. 25-1259 without an additional filing fee if Inhale appeals from an appealable final judgment in the underlying case within 60 days from 28 May 2025. This window closes approximately 27 July 2025 based on the order date.
The order that each party shall bear its own costs means neither Inhale nor Gravitron is entitled to recover appellate legal fees or expenses from the other. This is standard in jurisdictional dismissals and carries no implication about the underlying merits of the patent infringement claim or either party’s litigation conduct.
No. The dismissal is purely procedural — the court declined jurisdiction and made no ruling on the validity, scope, or infringement of US8393563B2. The patent retains its statutory presumption of validity under 35 U.S.C. § 282 and remains fully enforceable against third parties in appropriate proceedings.
US8393563B2, filed under application number US12/980330, covers a handheld tobacco grinder with windows — a mechanical consumer device combining a grinding mechanism with transparent viewing apertures in the housing.
