Johnson v. Chiappa Firearms USA: Triple Barrel Shotgun Patent Dismissed With Prejudice
Steve Johnson filed a patent infringement action against Chiappa Firearms USA in the Northern District of California, asserting US6935063B1 covering triple barrel shotgun technology. The parties reached a stipulated dismissal with prejudice under FRCP 41(a)(1)(A)(ii) after 149 days — each side bearing its own costs.
A Triple Barrel Shotgun Patent Dispute Ends by Mutual Agreement
On February 11, 2025, inventor Steve Johnson filed a patent infringement complaint against Chiappa Firearms USA, Ltd in the U.S. District Court for the Northern District of California (Case No. 5:25-cv-01427), presided over by Judge Noel Wise. Johnson asserted US6935063B1, a patent covering triple barrel shotgun technology (application no. US10/830995), against Chiappa USA’s firearm products in that category. Murthy Patent Law Inc. represented Johnson; Snell & Wilmer LLP defended Chiappa.
On July 10, 2025 — 149 days after filing — the parties jointly stipulated to dismiss the entire action with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The stipulation covers each and every count and claim in the complaint. Critically, dismissal is with prejudice, meaning Johnson is permanently barred from reasserting the same claims against Chiappa USA on US6935063B1. The cost-neutral structure — each party bearing its own fees and expenses — is consistent with a negotiated resolution rather than a capitulation by either side.
At 149 days, the case resolved well before typical district court milestones such as claim construction or summary judgment, suggesting the parties may have reached a commercial resolution — potentially a licensing agreement or cross-licensing arrangement — though the public record is silent on any underlying terms. The with-prejudice designation and mutual cost-bearing are hallmarks of a settled dispute, but no settlement agreement has been made public. What drove the resolution — whether a licence was granted, a design-around was accepted, or a business deal was struck — remains unknown from the docket.

Dismissed with prejudice: what the stipulated termination means for both parties
FRCP 41(a)(1)(A)(ii): Stipulated Dismissal Requires No Court Order
Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), parties may dismiss an action by filing a signed stipulation without requiring court approval. Here, both sides agreed — through counsel — to terminate all counts with prejudice. This mechanism is commonly used when parties have reached an off-docket resolution and wish to close the litigation cleanly and promptly.
Voluntary, bilateral, no merits rulingDismissal With Prejudice: Johnson Cannot Refile These Claims
A dismissal with prejudice operates as a final adjudication on the merits under res judicata principles. Johnson is permanently barred from bringing the same infringement claims against Chiappa USA based on US6935063B1. However, the patent itself remains in force — Johnson retains the ability to assert it against third parties who were not party to this action.
Permanent bar against Chiappa USA onlyChiappa USA Secures Finality — But Terms Remain Confidential
For Chiappa Firearms USA, the with-prejudice dismissal eliminates future litigation risk from Johnson on US6935063B1 for triple barrel shotgun products. The cost-neutral structure — each party bearing its own fees — suggests neither side was forced into an unfavourable position, consistent with a negotiated outcome. Whether Chiappa obtained a licence or simply agreed on a commercial resolution is not disclosed in the public record.
Future exposure on this patent extinguishedUS6935063B1 Remains Active — Other Firearm Makers Should Take Note
Despite the dismissal of this specific action, US6935063B1 continues in force as an enforceable patent. Other manufacturers developing or commercialising triple barrel shotgun products remain exposed to infringement risk from the same patent. The rapid pre-merits resolution limits the public record of claim scope analysis — meaning no claim construction order exists to guide third-party FTO assessments.

Official order — verbatim text
The stipulation’s explicit coverage of ‘each and every count and claim’ asserted in the complaint ensures no partial claims survive the dismissal. The with-prejudice designation forecloses any future action by Johnson against Chiappa USA on these specific claims under res judicata. Critically, the cost-neutral structure — where neither side pays the other’s fees — is typical of a negotiated commercial resolution and does not imply fault or weakness by either party. No merits ruling was made; the patent’s validity and claim scope remain fully intact.
US6935063B1 — Triple Barrel Shotgun Design and Mechanism
US6935063B1 (application no. US10/830995) protects a triple barrel shotgun — a distinctive firearm configuration featuring three barrels rather than the conventional single or double barrel arrangement. The patent covers the design and mechanical aspects of this multi-barrel shotgun format. This is a utility patent in the sporting arms and firearms engineering domain, representing a niche but commercially distinctive product category within the broader firearms market.
Triple barrel shotguns occupy a premium and specialist niche within the sporting firearms market. Chiappa Firearms — through its U.S. subsidiary — is one of the most prominent commercial producers of triple barrel shotgun models, making it a logical and commercially significant enforcement target for this patent. The fact that Johnson pursued infringement litigation rather than licensing negotiations upfront suggests confidence in the patent’s coverage of Chiappa’s product line. The patent’s continued enforceability post-dismissal means any competitor seeking to manufacture or import triple barrel shotguns into the U.S. market faces live FTO risk.
Should you run an FTO analysis against US6935063B1 for triple barrel shotgun products?
Any manufacturer, importer, or distributor of triple barrel shotgun products — or firearms engineers developing multi-barrel configurations — should treat US6935063B1 as a live enforcement risk. The Johnson v. Chiappa dismissal did not invalidate the patent or limit its claims via court order. Without a Markman ruling on record, the claim scope remains defined solely by the patent’s own language, and the risk of a new infringement action against non-Chiappa parties is unresolved.
PatSnap Eureka’s FTO Search Agent can map the claim landscape of US6935063B1, identify prosecution history estoppel, surface any inter partes review filings, and compare your product design against the asserted claims. For product teams developing triple barrel or multi-barrel shotgun configurations, an Eureka FTO report provides the documented clearance analysis needed before market entry — especially given the demonstrated willingness of this patent holder to litigate in federal court.

What this case signals for the firearms and sporting goods IP landscape
A fast, cost-neutral dismissal with prejudice in a firearms patent case leaves the underlying patent intact and enforcement risk live for competitors.
Pre-merits resolution leaves no public claim construction guidance
Because the case resolved in 149 days without any Markman hearing or summary judgment ruling, there is no judicial interpretation of the claims in US6935063B1 on the public record. Competitors designing triple barrel shotgun products must rely on the patent’s own claim language and prosecution history for FTO assessments — with no court guidance to calibrate scope.
With-prejudice + cost neutrality is a hallmark of negotiated resolution
Stipulated dismissals under FRCP 41(a)(1)(A)(ii) with each party bearing its own costs typically signal that the parties reached a commercial deal — whether a licence, royalty arrangement, or product design accommodation. The structure protects both parties: Johnson cannot refile; Chiappa USA avoids any fee award. Third parties should treat this as a possible licence grant, not an invalidation.
Johnson v Chiappa — key questions answered
Dismissal with prejudice permanently bars Steve Johnson from refiling the same patent infringement claims against Chiappa Firearms USA based on US6935063B1. Under res judicata principles, the dismissal operates as a final adjudication on the merits as between these two parties. The patent itself, however, remains valid and enforceable against other third parties not named in this action.
Steve Johnson asserted US6935063B1 (application no. US10/830995) against Chiappa Firearms USA. The patent covers triple barrel shotgun technology — a multi-barrel firearm design and mechanism. Chiappa Firearms is a prominent commercial producer of triple barrel shotgun models, making it the logical enforcement target for this patent.
The case resolved in 149 days, well before any claim construction hearing or merits ruling, which is consistent with the parties reaching a negotiated commercial resolution — potentially a licence, royalty agreement, or product design accommodation. The public docket does not disclose the underlying terms. The cost-neutral structure and with-prejudice dismissal are hallmarks of a privately settled dispute.
No. The stipulated dismissal with prejudice only bars Johnson from suing Chiappa Firearms USA again on these specific claims. US6935063B1 remains fully enforceable against any other manufacturer, importer, or distributor of triple barrel shotgun products who was not a party to this action. Other firearms companies should conduct FTO analysis before commercialising competing products.
Federal Rule of Civil Procedure 41(a)(1)(A)(ii) allows parties to dismiss an action by filing a signed stipulation without requiring court approval, provided the opposing party has answered or moved for summary judgment. It is a commonly used procedural mechanism when parties reach an off-docket resolution and wish to terminate litigation cleanly. Here, both Johnson and Chiappa USA — through their attorneys — filed the stipulation, requesting the court formally dismiss the entire case.
