LooseLeaf International v. CannVerify: Anti-Counterfeiting Patent Suit Settles in 100 Days
LooseLeaf International LLC filed suit against CannVerify LLC in the Southern District of California, asserting three patents covering anti-counterfeiting systems and methods. The parties reached a settlement agreement within 100 days, with each side bearing its own attorney fees and costs.
Three anti-counterfeiting patents, one swift settlement in S.D. Cal.
On September 30, 2024, LooseLeaf International LLC filed an infringement action against CannVerify LLC in the U.S. District Court for the Southern District of California (Case No. 3:24-cv-01746). LooseLeaf asserted three patents — US11736287B2, US12034842B2, and US11405194B2 — all directed to anti-counterfeiting systems and methods of use, a technology domain with growing commercial relevance in regulated product markets.
The case closed on January 8, 2025, just 100 days after filing, when LooseLeaf filed a voluntary dismissal under Fed. R. Civ. P. 41(a)(1)(A)(i), expressly citing a settlement agreement between the parties. The dismissal notice provides that each party bears its own respective attorney fees and costs, suggesting neither side extracted a fee award as part of the resolution. No defendant law firm appeared on record, which may indicate CannVerify resolved the matter before formal representation was fully engaged.
A 100-day resolution is notably rapid for multi-patent patent infringement litigation and suggests the parties likely reached commercial or licensing terms early in the proceeding. The absence of a merits ruling leaves the validity and scope of LooseLeaf’s three patents unresolved in the public record, which has implications for potential future enforcement. The specific terms of the underlying settlement agreement remain confidential and are not disclosed in the court filings.
Filing to Voluntary dismissal in 100 days
100 days — well below the median district court patent case duration of ~2.5 years
Voluntarily dismissed: what the settlement-driven exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff-controlled voluntary dismissal
A dismissal under Fed. R. Civ. P. 41(a)(1)(A)(i) is filed by the plaintiff before the defendant serves an answer or motion for summary judgment. It is the simplest form of voluntary dismissal and requires no court order. Here, LooseLeaf explicitly stated the dismissal was ‘pursuant to the parties’ settlement agreement,’ confirming this was not a unilateral abandonment but a negotiated exit.
Plaintiff-initiated exitThe public record is silent on prejudice designation
When a voluntary dismissal does not expressly state ‘with prejudice,’ Rule 41(a)(1)(B) generally treats it as without prejudice — meaning LooseLeaf could theoretically refile. However, the underlying settlement agreement may privately restrict refiling. The court filing does not disclose those terms. Parties reviewing this case should not assume either a permanent bar or an open door to future litigation — the true answer lies in the confidential settlement.
Prejudice status: undisclosedLooseLeaf exits with patents intact and no adverse ruling
LooseLeaf secured a settlement without any adverse finding on patent validity, claim scope, or infringement. All three asserted patents — US11736287B2, US12034842B2, and US11405194B2 — remain in force with no court-imposed limitations. This preserves LooseLeaf’s ability to enforce against other market participants, though the confidential settlement may impose constraints specific to CannVerify.
Patents remain enforceableCannVerify avoids merits ruling — at a negotiated cost
CannVerify escaped without a liability finding, invalidity ruling, or injunction on record. However, the settlement almost certainly involved commercial terms — potentially a licence, design-around commitment, or payment — that are not visible in the public record. No defendant counsel of record appeared in the docket, which may suggest early-stage resolution before full legal mobilisation. Each party bearing its own costs is a neutral cost outcome.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly attributes the exit to a settlement agreement, while specifying a mutual cost-bearing arrangement. This phrasing is legally precise: it is a plaintiff-unilateral filing that required no defendant signature or court order, yet the settlement attribution signals mutual agreement on underlying commercial terms. The absence of a prejudice designation in the public filing is legally significant — practitioners should not infer a final resolution bar without reviewing the private settlement instrument.
US11736287B2, US12034842B2 & US11405194B2 — Anti-Counterfeiting Systems
The three patents asserted — US11736287B2 (App. No. US17/808362), US12034842B2 (App. No. US18/218339), and US11405194B2 (App. No. US16/580476) — form a portfolio directed to anti-counterfeiting systems and associated methods of use. The sequential application numbers suggest a deliberate continuation or family strategy, with US11405194B2 representing the earliest filing (App. No. US16/580476) and US12034842B2 the most recent. This filing pattern is consistent with a portfolio built to cover both apparatus and method claims across successive generations of a core technology.
Anti-counterfeiting and product authentication patents have become strategically significant across regulated industries including cannabis, pharmaceuticals, luxury goods, and supply chain management. A portfolio of three patents with no adverse litigation history — as LooseLeaf’s now carries — represents a credible enforcement asset. Companies developing digital verification, QR-based authentication, blockchain provenance, or NFC-based anti-counterfeiting systems should assess whether their products fall within the claim scope of this family, particularly given the demonstrated willingness to litigate.
Should you run an FTO against US11736287B2, US12034842B2, and US11405194B2?
Any company developing or deploying anti-counterfeiting, product authentication, or verification systems — particularly in regulated markets such as cannabis, pharma, or consumer goods — should conduct a freedom-to-operate analysis against LooseLeaf’s patent family. The 100-day settlement demonstrates that LooseLeaf is an active enforcer willing to file in federal court, and the three-patent portfolio provides overlapping claim coverage that increases the risk of a multi-front infringement allegation.

What this case signals for the anti-counterfeiting IP landscape
Three patents, a 100-day close, and no merits ruling: the pattern suggests enforceability pressure that resolved commercially, not judicially.
Multi-patent portfolios accelerate early settlement pressure
Asserting three patents simultaneously raises the cost and complexity of defence. CannVerify faced invalidity and non-infringement arguments across all three, likely driving early commercial resolution. IP teams operating in anti-counterfeiting and authentication markets should audit their exposure to overlapping patent families before receiving a demand letter.
No adverse ruling leaves LooseLeaf’s patents fully available for re-use
Because the case settled on voluntary dismissal without a merits adjudication, LooseLeaf’s three anti-counterfeiting patents carry no negative litigation history. This strengthens their enforceability signal in any future action. Competitors and adjacent technology developers should treat US11736287B2, US12034842B2, and US11405194B2 as actively asserted and commercially live.
LooseLeaf v CannVerify — key questions answered
LooseLeaf International LLC asserted three patents: US11736287B2 (App. No. US17/808362), US12034842B2 (App. No. US18/218339), and US11405194B2 (App. No. US16/580476). All three are directed to anti-counterfeiting systems and methods of use. The case was filed on September 30, 2024, in the Southern District of California.
The case was voluntarily dismissed by LooseLeaf under Fed. R. Civ. P. 41(a)(1)(A)(i) on January 8, 2025, citing a settlement agreement between the parties. Each party bears its own attorney fees and costs. The dismissal does not specify ‘with prejudice’ or ‘without prejudice’ in the public filing, leaving the refiling question dependent on the confidential settlement terms.
No. Because the case resolved on voluntary dismissal without any merits adjudication, there is no court ruling on the validity, infringement, or claim scope of US11736287B2, US12034842B2, or US11405194B2. All three patents remain in force and carry no negative litigation history from this proceeding.
The 100-day resolution is well below the typical multi-patent district court case timeline. No defendant counsel of record appeared in the docket, which suggests CannVerify may have engaged in settlement discussions very early. Asserting three patents simultaneously increases defence complexity and cost, which typically accelerates negotiation. The specific commercial terms of the settlement are not publicly disclosed.
Yes. LooseLeaf’s three patents — including US11736287B2 — remain enforceable with no adverse court ruling on their validity or scope. The swift settlement in this case may indicate a preference for licensing over protracted litigation, but LooseLeaf’s demonstrated willingness to file in federal court means companies in the authentication and anti-counterfeiting space should monitor this portfolio and consider a freedom-to-operate analysis.
