Shenandoah Manufacturing v. AIHG: Face Mask Patent Case Transferred to Richmond Division
Shenandoah Manufacturing Partners and co-plaintiffs filed an infringement action against American International Healthcare Group over protective face mask patent US11052269B1. After the court dismissed the sole patent claim in November 2023, the case was transferred from the Alexandria Division to the Richmond Division of the Eastern District of Virginia in just 215 days — the surviving dispute now centres on SMP’s Operating Agreement.
Patent claim dismissed, contract dispute drives venue transfer to Richmond
On July 14, 2023, Shenandoah Manufacturing Partners, LLC, Aorta Medical, Inc., Brian Fortier, William Bailey, and WTB Consulting, Inc. filed suit in the Eastern District of Virginia against American International Healthcare Group, LLC and Michael Greenway, asserting infringement of US11052269B1, a patent covering protective face masks. The case was initially filed in Richmond but administratively reassigned to the Alexandria Division under the District’s practice of routing patent matters across its divisions.
On November 16, 2023, the court dismissed the only patent count in the case, simultaneously dismissing third-party defendant Gavin Law Offices, PLC. With no patent claims surviving, plaintiffs filed a Corrected Motion to Transfer Venue on December 8, 2023, arguing — and the court agreeing — that no basis remained for the case to sit in Alexandria. On February 13, 2024, the court granted the transfer under 28 U.S.C. § 1404(b), moving the matter to the Richmond Division where SMP is headquartered and all counter-defendants reside. Defendants did not oppose the motion.
The 215-day trajectory from filing to transfer is notable because the case effectively transformed from a patent infringement dispute into a contract controversy centred on SMP’s Operating Agreement within roughly four months. The uncontested nature of the transfer motion suggests the defendants — Arizona residents — saw little tactical advantage in Alexandria. The public record does not disclose the full merits of the Operating Agreement dispute or the outcome of the pending Motion to Dismiss now before the Richmond Division.

From Alexandria to Richmond: what the venue transfer means for both parties
Transfer under § 1404(b): intra-district, not dismissal
A transfer under 28 U.S.C. § 1404(b) moves a case between divisions within the same district rather than terminating it. The court retains jurisdiction; pleadings, motions, and the docket carry over intact. Here, the court applied § 1404(b) — which requires party motion or consent — rather than the § 1406(a) improper-venue basis the plaintiffs originally invoked, signalling a convenience and efficiency rationale rather than a procedural defect.
No dismissal — case continues in RichmondPatent claim dismissed before transfer — IP exposure reduced
The sole patent infringement count against AIHG was dismissed by the court on November 16, 2023 — prior to any transfer ruling. This means US11052269B1 was not adjudicated on the merits; no invalidity finding was made. For SMP, the patent survives legally intact, but the plaintiffs secured no infringement judgment. The surviving dispute is contractual, centred on SMP’s Operating Agreement, leaving the patent’s enforceability unchallenged and undecided.
Patent claim dismissed — no merits rulingDefendants gain Richmond forum; Motion to Dismiss still live
AIHG and Michael Greenway — both Arizona residents — did not oppose the transfer, suggesting Richmond presents no material disadvantage. Crucially, their Motion to Dismiss (Dkt. 71) remains pending on the docket and carries over to the Richmond Division. This gives defendants a live dispositive vehicle against the surviving Operating Agreement claims. The transfer itself is neutral procedurally for defendants; the strategic contest now shifts to that pending motion.
Motion to Dismiss pending in RichmondFace mask patent unresolved: freedom-to-operate uncertainty persists
Because the patent claim was dismissed without a merits ruling on US11052269B1, competitors in the protective face mask and respiratory barrier space cannot rely on this case as precedent for invalidity or non-infringement. The patent remains enforceable and may be asserted again. Companies manufacturing or distributing protective face masks should treat this case’s outcome as neutral — neither a clearance nor a confirmation of infringement — and consider independent FTO analysis.

Official order — verbatim text
The court’s order is procedural rather than substantive: it resolves only the question of intra-district venue under 28 U.S.C. § 1404(b) and makes no ruling on the merits of any remaining claim. The language granting the transfer while preserving AIHG’s Motion to Dismiss confirms the Richmond Division inherits the case in precisely the posture it left Alexandria. Neither party gains a substantive advantage from the transfer itself; the operative legal contest is now the pending dismissal motion.
US11052269B1 — Protective face mask respiratory barrier device
US11052269B1 (application number US17/015869) covers protective face mask technology in the respiratory barrier device category. The patent is held by the plaintiff group anchored by Shenandoah Manufacturing Partners, LLC. While the specific claims were not adjudicated in this proceeding, the patent’s assertion in an infringement context against a healthcare products distributor suggests it covers commercial-grade protective mask design or construction features relevant to mass-market or medical supply channels.
The protective face mask sector experienced intense patent activity during and after the COVID-19 pandemic, with numerous design, utility, and materials patents asserted across supply chain participants. US11052269B1’s continued enforceability — following dismissal of the infringement count without prejudice to invalidity arguments — means it represents a live risk for manufacturers, distributors, and importers of protective face masks who have not conducted independent freedom-to-operate analysis against this specific patent family.
Should your team run an FTO against US11052269B1?
Any company manufacturing, distributing, importing, or retailing protective face masks or respiratory barrier devices in the United States should treat US11052269B1 as an active enforcement risk. This case demonstrates the patent holder’s willingness to assert the patent in federal court. Because the infringement count was dismissed without a validity ruling, no judicial clearance exists. R&D teams developing next-generation mask designs and procurement teams sourcing protective equipment are both exposed without a documented FTO.

What this case signals for the protective face mask IP landscape
A patent case that collapses into a contract dispute before trial sends distinct signals for how medical device IP portfolios are being deployed and defended.
Patent claim dismissal before trial leaves US11052269B1 fully enforceable
No court has ruled on the validity or infringement scope of US11052269B1. Companies in the protective face mask and respiratory barrier sector should not treat the dismissal of the infringement count as a green light. The patent was not invalidated; it was simply not litigated to judgment. Independent FTO analysis remains the only reliable path to clearance.
Intra-district transfers signal how patent courts manage post-dismissal dockets
The Eastern District of Virginia’s practice of routing patent matters to Alexandria — and then transferring non-patent residue back to the originating division — illustrates how specialised patent docket management can affect litigation costs and forum strategy. Plaintiffs filing in EDVA should model venue reassignment risk when patent claims are legally fragile from the outset.
Shenandoah v American — key questions answered
The sole patent infringement count was dismissed by the Eastern District of Virginia on November 16, 2023, before any merits ruling on US11052269B1. No invalidity or non-infringement finding was made. The dismissal of the patent count prompted plaintiffs to seek transfer of the surviving Operating Agreement dispute from the Alexandria Division to the Richmond Division.
The case was originally assigned to Alexandria under EDVA’s practice of routing patent matters across divisions. After the patent count was dismissed, no basis remained for Alexandria jurisdiction. SMP is headquartered in Glen Allen, Virginia (Richmond Division), all counter-defendants reside in the Richmond Division, and defendants — Arizona residents — did not oppose the transfer. The court applied 28 U.S.C. § 1404(b).
No. The patent count was dismissed without any ruling on validity or infringement. US11052269B1 remains legally enforceable. The dismissal provides no FTO clearance for competitors. The patent holder retains the right to assert it in future proceedings against the same or different defendants.
Per the February 13, 2024 transfer order, AIHG’s Motion to Dismiss (Dkt. 71) was explicitly preserved and remains pending on the docket. It carries over to the Richmond Division of the Eastern District of Virginia where it will be heard by the reassigned judge. The outcome of this motion will determine whether the Operating Agreement claims survive.
The court applied 28 U.S.C. § 1404(b), which permits transfer between divisions within the same district upon motion, consent, or stipulation. The plaintiffs had originally moved under § 1406(a) — which addresses improper venue — but the court found § 1404(b) the proper basis, as the transfer was driven by convenience and the changed nature of the surviving claims rather than an initial venue defect.
