VPR Brands v. O.pen Vape: Vaporizer Patent Suit Dismissed in 7 Days
VPR Brands, LP asserted US8205622B2 — covering vaporizer and cannabis oil delivery technology — against O.pen Vape LLC in Colorado. The case was voluntarily dismissed without prejudice just seven days after filing, with each party bearing its own costs.
A vaporizer patent suit that ended before it began
On December 3, 2024, VPR Brands, LP filed an infringement action against O.pen Vape LLC in the Colorado District Court, asserting US8205622B2 — a patent directed to vaporizer technology encompassing batteries, cartridges, dab pen and flower vaporizer components, and medical marijuana oil vaporizers. O.pen Vape is a prominent brand in the cannabis vaporizer market, making it a commercially significant target for enforcement of vaporizer hardware IP.
Just seven days later, on December 10, 2024, VPR Brands filed a Notice of Voluntary Dismissal pursuant to Fed. R. Civ. P. 41(a)(1)(A)(i), dismissing the lawsuit without prejudice. The dismissal was filed before any answer or motion for summary judgment was served by O.pen Vape, satisfying the procedural requirements for a unilateral voluntary dismissal. Each party was designated to bear its own costs, attorneys’ fees, and expenses.
A resolution of this speed — seven days — typically signals that the matter was resolved or redirected through channels outside the court record, such as a licensing negotiation, a settlement-in-principle, or a strategic decision to re-file in a different venue or posture. The without-prejudice designation means VPR Brands has preserved the option to reassert these claims. The public record is silent on whether any commercial agreement underlies the dismissal.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to exit before answer
Fed. R. Civ. P. 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order at any time before the defendant has served an answer or a motion for summary judgment. VPR Brands exercised this right unilaterally. Because no responsive pleading had been filed by O.pen Vape, the dismissal required no judicial approval and is effective as of filing.
Unilateral plaintiff exitWithout prejudice: the distinction that matters most here
A without-prejudice dismissal does not adjudicate the merits — VPR Brands may refile the same claims against O.pen Vape in the future. A with-prejudice dismissal would permanently bar refiling. The verdict text explicitly states ‘without prejudice,’ preserving VPR Brands’ enforcement options. Note: if a plaintiff refiles and dismisses a second time, the second dismissal may operate as a with-prejudice bar under Rule 41(a)(1)(B).
Refiling risk remains openO.pen Vape exits without admissions — but risk persists
O.pen Vape faces no judgment, no injunction, and no admission of infringement. The cost-neutral terms confirm no financial transfer occurred via court order. However, the without-prejudice dismissal means O.pen Vape cannot treat this case as resolved. VPR Brands retains the right to reassert US8205622B2, and a future action could proceed with more preparation on both sides.
No judgment, exposure remainsSpeed of exit suggests undisclosed driver — watch for a refile
A seven-day case lifecycle is consistent with a pre-filing licensing dialogue that reached resolution quickly, a strategic decision to change venue or claim set, or a discovery that affected the plaintiff’s immediate enforcement calculus. Companies operating in the cannabis vaporizer hardware space — particularly those selling cartridges, batteries, and oil delivery components — should monitor VPR Brands’ docket activity for a potential refile or a broader enforcement campaign.

Official order — verbatim text
The voluntary dismissal notice invokes Rule 41(a)(1)(A)(i) precisely, signalling that VPR Brands acted before any responsive pleading was filed — a procedurally clean exit requiring no court order. The explicit ‘without prejudice’ language is significant: it preserves all claims against O.pen Vape and avoids any preclusive effect on the patent’s enforceability. The cost-neutral terms suggest no financial resolution was ordered by the court, though the public record cannot confirm whether a private commercial arrangement was reached contemporaneously.
US8205622B2 — Electronic vaporizer and cannabis oil delivery device
US8205622B2, filed under application number US12/437511, covers electronic vaporizer technology relevant to cannabis oil and botanical material delivery. The patent’s claims are directed to the hardware architecture of vaporizer systems — encompassing battery components, cartridge interfaces, and oil atomisation mechanisms. Products asserted to fall within scope include batteries, cartridges, dab pens, flower vaporizers, and medical marijuana oil vaporizers, suggesting broad claim coverage across the cannabis hardware stack.
In the rapidly expanding cannabis vaporizer market, foundational hardware patents like US8205622B2 carry significant commercial leverage. VPR Brands’ willingness to assert this patent against a well-known Colorado brand signals active enforcement intent. For competitors and OEM suppliers operating in cartridge manufacturing, battery supply, or private-label vaporizer assembly, this patent represents a live infringement risk. The breadth of the accused product categories suggests the claims may read on standardised hardware used industry-wide.
Should you run an FTO analysis against US8205622B2?
Any company manufacturing, importing, or distributing cannabis oil cartridges, vaporizer batteries, dab pens, or pen-style medical marijuana delivery devices in the US market should assess whether US8205622B2 reads on their products. The asserted product scope in this case is broad — covering both hardware components and finished vaporizer systems. With the case closed without prejudice, VPR Brands retains full enforcement rights, making a proactive FTO assessment commercially prudent before entering or expanding in this product category.

What this case signals for the cannabis vaporizer IP landscape
A seven-day patent suit in cannabis vaporizer hardware raises more questions than it answers — and carries real implications for the sector.
VPR Brands is an active enforcer of vaporizer hardware IP
VPR Brands has demonstrated willingness to assert US8205622B2 and related patents across the cannabis vaporizer supply chain. Any company selling cartridges, batteries, dab pens, or oil vaporizer components should treat this dismissal as a pause, not a conclusion — the without-prejudice terms leave enforcement options fully intact.
Rule 41 exits this fast typically signal off-record activity
When a patent suit closes in under ten days with no responsive pleading filed, the most common explanations are a licensing agreement, a settlement-in-principle, or a tactical repositioning. None of these are confirmed by the public record. Competitors of O.pen Vape should assess whether a licensing framework now exists that could be extended to the broader market.
VPR v O.pen — key questions answered
VPR Brands, LP filed a patent infringement action against O.pen Vape LLC in Colorado District Court on December 3, 2024, asserting US8205622B2 covering vaporizer technology. The case was voluntarily dismissed without prejudice seven days later on December 10, 2024, with each party bearing its own costs.
Dismissed without prejudice means VPR Brands has not waived or lost the right to refile the same patent infringement claims against O.pen Vape in the future. No merits determination was made. If VPR Brands refiles and subsequently dismisses a second time, however, Rule 41(a)(1)(B) may treat that second dismissal as with prejudice.
US8205622B2, filed as application US12/437511, covers electronic vaporizer hardware technology. In this case, the accused products included batteries, cartridges, the Conceal product line, dab pen and flower vaporizer products and components, and medical marijuana oil vaporizers — suggesting broad claim coverage across O.pen Vape’s hardware portfolio.
A seven-day case lifecycle is consistent with several scenarios: a pre-filing or immediate post-filing licensing or settlement agreement, a decision to refile in a different venue or with a revised claim set, or a tactical withdrawal pending further investigation. The public record does not confirm which applied. The Rule 41(a)(1)(A)(i) mechanism requires no court order when filed before any responsive pleading.
No. A voluntary dismissal without prejudice under Rule 41(a)(1)(A)(i) has no effect on the validity or enforceability of the asserted patent. US8205622B2 remains in force and fully enforceable. VPR Brands retains all rights to assert it in future litigation or licensing negotiations against O.pen Vape or any other party.
