Well Cell Global v. Calvit & Insulinic: $16.77M Judgment for Insulin IP Theft
Well Cell Global LLC secured a $16.77 million final judgment — including $6 million in exemplary damages — against former licensees who continued operating competing Insulinic clinics after their licenses were revoked. The Texas Southern District Court found willful trade secret misappropriation, trademark infringement, and unfair competition across a 979-day litigation.
Former Insulinic Licensees Hit With $16.77M Judgment for Willful IP Theft
Filed in September 2022 in the Southern District of Texas before Judge Lee H. Rosenthal, this case pitted Well Cell Global LLC and affiliated plaintiffs against a network of former franchisee-style licensees operating under the Insulinic brand across Hawaii, Hialeah, and Lafayette. The dispute centred on three patents — US9654595B2, US9652595B1, and US10533990B2 — covering insulin infusion pumps, kits, and IV tubing cassettes, as well as the proprietary microburst insulin resensitization method and associated trademarks used to treat diabetes and metabolic disorders.
The case resolved through a dual-track process: some defendants entered a stipulated consent judgment and permanent injunction, while the remaining defendants — Marc Pierre Desgraves IV, Charles Alexander Elliott, and Insulinic of Hawaii LLC — faced summary judgment. Judge Rosenthal granted plaintiffs’ summary judgment on both liability and damages, entering a final judgment of $16,771,973.71 comprising $9.09M in lost profits and disgorgement, $6M in exemplary damages, $683,330.98 in attorney’s fees, $2,154 in costs, and $997,673.79 in prejudgment interest at 7.5% compounded daily.
The 979-day duration reflects the complexity of coordinating claims against multiple defendants across several states, including managing a mid-litigation consent judgment with one group while pursuing summary judgment against another. The court’s finding of willful and malicious misappropriation — triggering exemplary damages at twice the base award — suggests the evidence of continued post-revocation use was substantial. The public record does not disclose the precise damages methodology underlying the $4.54M actual damages figure, nor the royalty rate basis for the $1.08M reasonable royalty component.

S.D. Texas grants summary judgment: what the $16.77M ruling means
Summary judgment on liability and damages — a rare dual grant
The court granted summary judgment on both liability and damages — an unusually complete pretrial resolution. This means no genuine dispute of material fact existed on either issue: the remaining defendants were found legally liable for misappropriation and infringement, and the damages quantum was fixed without trial. The willfulness finding unlocked exemplary damages at twice the base award under 18 U.S.C. § 1836(b)(3)(C) and the Texas TUTSA equivalent.
Judgment as a matter of lawPlaintiffs secure permanent injunction and $16.77M total award
Well Cell Global and its affiliates obtained not only monetary relief but a permanent injunction barring all remaining defendants from practicing the microburst insulin resensitization method, using plaintiffs’ trademarks or domain names, or disclosing proprietary training materials. The injunction binds successors and assigns, giving plaintiffs durable exclusivity over their licensed network. Prejudgment interest at 7.5% compounded daily from September 2022 further enhanced the economic recovery.
Permanent injunction grantedDefendants face joint and several liability — no trial opportunity
Desgraves, Elliott, and Insulinic of Hawaii LLC are jointly and severally liable for the full $16.77M — meaning each can be pursued individually for the entire sum. The summary judgment ruling closed off a trial defence, and the permanent injunction prevents any continued operation. Their post-revocation continuation of licensed activities, including use of training modules and the Insulinic brand, was characterised by the court as willful and malicious, a finding that significantly limits any appeal prospects on damages.
Full joint and several liabilityExemplary damages set a deterrent benchmark for medical franchise IP
The $6M exemplary award — roughly 66% of the base damages — signals that courts will apply maximum statutory multipliers when licensees continue operating after explicit revocation. For healthcare IP licensors, this outcome reinforces the value of documented revocation notices and tightly drafted licence agreements. For competitors in the insulin therapy and metabolic disease treatment space, the permanent injunction effectively rings-fences Well Cell’s microburst method and Insulinic branding from ex-licensee channels.

Official order — verbatim text
The final judgment’s scope is notably broad: it resolves all claims on the merits against the remaining defendants via summary judgment — an outcome that reflects the court’s assessment that no triable issue existed on liability or quantum. The willfulness finding under both federal DTSA (18 U.S.C. § 1836) and Texas TUTSA triggers statutory exemplary damage multipliers, which the court applied to reach $6M in punitive relief. The joint and several liability structure, combined with a permanent injunction binding successors and assigns, creates a durable enforcement posture for plaintiffs well beyond the litigation itself.
US9654595B2, US9652595B1 & US10533990B2 — Insulin Infusion Delivery Systems
The three asserted patents — US9654595B2, US9652595B1, and US10533990B2 — cover the hardware layer of Well Cell’s proprietary microburst insulin resensitization platform: insulin infusion pumps, treatment kits, and intravenous tubing cassettes designed to deliver controlled exogenous insulin infusions for the treatment of diabetes and metabolic disorders. The patents protect both the physical delivery infrastructure and, in combination with the trade secrets at issue, the clinical method by which insulin is administered in precise micro-doses to achieve resensitization rather than conventional glycaemic control.
In the context of this litigation, the patents anchored the enforceability of Well Cell’s exclusive licensing model — converting clinical know-how into defensible IP that former licensees could not legally replicate after revocation. For competitors in the diabetes treatment and metabolic disorder therapy space, the combination of patented delivery hardware and trade secret clinical protocols creates a layered exclusivity barrier. Any entity commercialising intravenous insulin infusion therapy in the U.S. should assess exposure against all three patent families before clinical deployment.
Should you run an FTO against US9654595B2, US9652595B1 & US10533990B2?
Any company developing, manufacturing, or deploying intravenous insulin infusion systems — including pump hardware, cassette components, or clinical delivery kits for metabolic disorder treatment — should conduct a freedom-to-operate assessment against these three patent families. The court’s final judgment confirms that the claim scope is judicially validated and actively enforced. Ex-licensees, white-label device makers, and telemedicine platforms offering insulin resensitization services face particular exposure given the injunction’s broad reach into training materials and branding.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the independent and dependent claims of US9654595B2, US9652595B1, and US10533990B2, identify file-history prosecution disclaimers that may narrow enforceability, and flag related continuation or divisional applications that could extend the exclusivity window. For medtech and diabetes care R&D teams, this analysis is a prerequisite before any commercial launch in the U.S. insulin infusion therapy market.

Portfolio viewWhat this case signals for the medical treatment IP licensing landscape
A $16.77M willfulness finding against ex-licensees resets risk calculus for healthcare IP franchise operators and their competitors.
Revocation documentation is now a litigation asset
The court’s willfulness finding was anchored in the defendants’ continuation of licensed activities after explicit revocation. IP licensors in medtech and healthcare should treat revocation notices as litigation-grade evidence — timestamped, served formally, and followed up with demand letters that create a clear post-revocation timeline.
Joint and several liability amplifies recovery against franchisee networks
Structuring claims against all clinic operators jointly and severally — rather than individually — gave plaintiffs maximum collection leverage. For IP owners dealing with distributed franchise or licensee networks, this approach ensures that solvency of any single defendant does not cap total recovery. The $16.77M award reflects the aggregate harm across multiple competing clinics.
Microburst insulin method patents create enforceable exclusivity zones
The three asserted patents — covering insulin infusion systems and IV delivery cassettes — formed the technical backbone of the injunction. Any competitor or ex-licensee attempting to design around these claims faces a court-confirmed scope that extends to training materials, protocols, and even social media branding. Freedom-to-operate analysis is essential before entering the insulin resensitization therapy market.
Consent judgment plus summary judgment strategy maximises settlement pressure
Plaintiffs resolved claims against one defendant group via stipulated consent judgment while simultaneously pressing summary judgment against holdouts. This bifurcated strategy isolates non-settling defendants, deprives them of co-defendant testimony, and creates a public record of liability findings that increases settlement pressure on remaining parties — a template worth noting for multi-defendant IP enforcement campaigns.
Well v Shawn — key questions answered
The court entered a final judgment of $16,771,973.71 against the remaining defendants jointly and severally. This comprised $9,088,814.94 in lost profits and disgorgement, $6,000,000 in exemplary damages, $683,330.98 in attorney’s fees, $2,154 in costs, and $997,673.79 in prejudgment interest at 7.5% compounded daily from September 7, 2022.
Well Cell Global and affiliated plaintiffs asserted trade secret misappropriation under the federal Defend Trade Secrets Act (18 U.S.C. § 1836) and Texas TUTSA, trademark infringement, and unfair competition. The claims arose from former licensees continuing to operate Insulinic-branded clinics and use plaintiffs’ proprietary microburst insulin resensitization method after their licences were revoked.
Three patents were asserted: US9654595B2, US9652595B1, and US10533990B2, covering insulin infusion pumps, kits, and IV tubing infusion cassettes. These patents protected the hardware infrastructure underlying Well Cell’s proprietary microburst insulin resensitization platform for treating diabetes and metabolic disorders.
The court found that the remaining defendants’ misappropriation of trade secrets and trademark infringement was willful and malicious. Under 18 U.S.C. § 1836(b)(3)(C) and Texas Civ. Prac. & Rem. Code § 134A.004, willful misappropriation entitles a plaintiff to exemplary damages up to twice the base monetary award. The court awarded $6,000,000 in exemplary damages, consistent with these statutory provisions.
The permanent injunction bars the remaining defendants — and their successors, assigns, and agents — from practising the microburst insulin resensitization method or any exogenous IV insulin infusion therapy, using Well Cell’s trademarks or confusingly similar marks, disclosing proprietary training materials, or operating internet domains or social media accounts incorporating plaintiffs’ trademarks. The defendants were also ordered to transfer any such domain names to plaintiffs’ control.
