GCE Gas Control Equipment v. VBOX: Federal Circuit Appeal Voluntarily Dismissed
GCE Gas Control Equipment Inc. appealed a patentability ruling against VBOX Inc. at the Federal Circuit, asserting US11389614B2 covering a removable cartridge for oxygen concentrators. The parties agreed to dismiss the proceeding under Fed. R. App. P. 42(b) after just 98 days, with each side bearing its own costs.
Federal Circuit appeal ends by mutual agreement, merits unresolved
GCE Gas Control Equipment Inc. filed this appeal at the Court of Appeals for the Federal Circuit on 19 August 2024, challenging a patentability determination in an invalidity or cancellation action concerning US11389614B2. That patent, with application number US15/931716, covers a removable cartridge for an oxygen concentrator — a device category with direct relevance to medical and industrial gas supply markets. The defendant, VBOX Inc., had successfully obtained a ruling below calling the patent’s validity into question.
The appeal closed on 25 November 2024, just 98 days after filing. The parties jointly agreed to dismiss the proceeding under Federal Rule of Appellate Procedure 42(b), and the Federal Circuit’s order reflects that mutual consent. Crucially, the public record does not specify whether the dismissal was with or without prejudice — FRAP 42(b) dismissals can carry either condition depending on the parties’ stipulation, and the available record is silent on this point. Each side was ordered to bear its own costs, suggesting a negotiated resolution rather than a unilateral withdrawal.
A 98-day lifespan at the Federal Circuit is notably short and suggests the parties reached a commercial or licensing resolution promptly after the appeal was docketed — a pattern consistent with leverage-driven appellate filings. What drove the settlement or agreement, whether GCE retained any licensing rights or whether VBOX secured a freedom-to-operate position, remains unknown from the public record. The validity of US11389614B2 was never adjudicated on the merits at the appellate level, leaving the patent’s enforceability status commercially uncertain.

Appeal voluntarily dismissed: what the FRAP 42(b) order means for both parties
FRAP 42(b) dismissal ends appeal without merits ruling
Federal Rule of Appellate Procedure 42(b) allows parties to dismiss an appeal by stipulation at any time. The Federal Circuit’s order confirms the dismissal was consensual. Critically, no court reached the merits of the patentability challenge, meaning the underlying validity dispute — whether US11389614B2 should survive or be cancelled — was never resolved by an appellate tribunal.
No merits adjudicationWith or without prejudice? The public record is silent
FRAP 42(b) dismissals can be entered with or without prejudice to refiling, depending on the parties’ stipulation. The published order does not specify which applies here. This distinction matters significantly: a with-prejudice dismissal would bar GCE from re-raising the same appellate arguments; a without-prejudice dismissal could leave that door open. Practitioners should treat the enforceability status of US11389614B2 as unresolved absent further disclosure.
Prejudice status unconfirmedGCE’s patent survives appeal — but validity cloud remains
GCE Gas Control Equipment filed this appeal to defend US11389614B2 against a patentability challenge. The voluntary dismissal means the adverse ruling from the tribunal below was not reversed on appeal, but neither was it affirmed by the Federal Circuit. The patent technically remains in existence, though the underlying cancellation or invalidity finding — if it stands — may constrain GCE’s enforcement options depending on the precise procedural posture of the originating proceeding.
Validity status uncertainOxygen concentrator IP landscape left without definitive guidance
Because the Federal Circuit issued no merits ruling, competitors and product teams in the oxygen concentrator and portable medical gas sector cannot rely on this proceeding as precedent for or against the patentability of removable cartridge designs covered by US11389614B2. Companies evaluating freedom-to-operate in this space should conduct independent analysis rather than drawing conclusions from this dismissal alone.

Official order — verbatim text
The Federal Circuit’s order confirms a purely procedural exit: the proceeding was dismissed by party agreement under FRAP 42(b), with no opinion on the merits of the patentability challenge. The cost-neutral directive — each side bearing its own — is consistent with a negotiated resolution. The order provides no guidance on the validity of US11389614B2, the scope of any surviving claims, or the legal effect of the underlying tribunal’s patentability finding. Practitioners should look to the originating proceeding’s record to assess the standing of any invalidity or cancellation determination.
US11389614B2 — Removable cartridge for oxygen concentrator
US11389614B2, filed under application number US15/931716, protects a removable cartridge design for use in oxygen concentrators. Oxygen concentrators separate ambient air to deliver enriched oxygen, and modular or removable cartridge architectures enable serviceability, filter replacement, and product differentiation in both medical and industrial gas supply contexts. The patent’s grant positions GCE Gas Control Equipment as a holder of structural IP in the device-level architecture of portable or stationary oxygen delivery hardware.
From a competitive standpoint, a patent covering removable cartridge mechanisms in oxygen concentrators sits at the intersection of medical device design and consumable supply chains — a commercially significant position. VBOX Inc.’s challenge to this patent’s validity suggests the technology is commercially relevant enough to contest. With the Federal Circuit appeal resolved without merits adjudication, the patent represents a continuing uncertainty for competitors designing cartridge-based oxygen concentrator products, particularly those evaluating whether their architectures design around or potentially infringe the asserted claims.
Should you run an FTO analysis against US11389614B2?
Any company designing, manufacturing, or distributing removable cartridge systems for oxygen concentrators — whether for medical, homecare, or industrial gas applications — should treat US11389614B2 as a live risk. The Federal Circuit’s dismissal without a merits ruling does not extinguish the patent or its claims. If your product roadmap includes modular or replaceable cartridge architectures in oxygen concentrator hardware, an independent freedom-to-operate analysis is warranted before commercial launch or market entry.

What this case signals for the oxygen concentrator IP landscape
A quick Federal Circuit dismissal by agreement typically signals one of two things: a licensing deal struck in the shadow of appeal, or a strategic retreat.
Speed of dismissal suggests a negotiated exit, not abandonment
At 98 days, this appeal resolved before substantive Federal Circuit briefing would typically be complete. That pace is consistent with parties reaching a commercial agreement — licensing, cross-licensing, or a covenant not to sue — shortly after the appeal was docketed. IP teams tracking GCE or VBOX should watch for licensing disclosures or product announcements.
US11389614B2 remains a live enforcement risk — validity unresolved
The absence of a Federal Circuit merits ruling means the patent has not been definitively invalidated at the appellate level. Companies making or distributing removable cartridge assemblies for oxygen concentrators should not treat this dismissal as clearing the IP landscape. Independent FTO analysis against US11389614B2 remains advisable.
GCE v VBOX — key questions answered
The Federal Circuit appeal was voluntarily dismissed by agreement of the parties under Fed. R. App. P. 42(b) on 25 November 2024, 98 days after filing. The court issued no merits ruling on the patentability of US11389614B2. Each side was ordered to bear its own costs.
A FRAP 42(b) dismissal is procedural — it terminates the appeal without the Federal Circuit ruling on whether the patent is valid or invalid. The underlying patentability determination from the tribunal below may retain legal effect depending on the specific proceeding type, but the appellate record provides no merits guidance. The patent’s enforceability should be treated as unresolved.
The public record does not specify. The Federal Circuit’s order confirms mutual agreement and cost-neutrality but is silent on whether the dismissal was entered with or without prejudice to refiling. Practitioners should not assume either condition without further disclosure from the parties.
US11389614B2, filed as application US15/931716, is held by GCE Gas Control Equipment Inc. and covers a removable cartridge for oxygen concentrators — devices that separate ambient air to deliver enriched oxygen for medical or industrial use. The patent’s modular cartridge architecture is the subject of the patentability dispute with VBOX Inc.
Yes, caution is warranted. The voluntary dismissal does not invalidate the patent or its claims. Companies designing removable or modular cartridge systems for oxygen concentrators should conduct independent freedom-to-operate analysis. The lack of a Federal Circuit merits ruling leaves the patent’s enforceability scope commercially uncertain.
