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.

Case overview

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.

Court ruling

S.D. Texas grants summary judgment: what the $16.77M ruling means

Legal mechanism

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 law
Patent holder outcome

Plaintiffs 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 granted
Challenger outcome

Defendants 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 liability
Commercial implications

Exemplary 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 verdict

Official order — verbatim text

“The plaintiffs, Well Cell Global LLC, Well Cell Support LLC, and Diabetes Relief LLC (“Plaintiffs”), have entered into a stipulated consent judgment with Defendants, Shawn Paul Calvit, Patrick Dale Leleux, MD, Insulinic LLC, Insulinic of Lafayette LLC, Insulinic of Hialeah LLC, Insulinic of Gretna, LLC, Insulinic of Hammond, LLC, and Integral Medicine Group, Inc. (see Docket Entry Nos. 211, 212). Plaintiffs have also dismissed one of the defendants, Diabetes Management Clinic, LLC (see Docket Entry No. 218), and have moved for summary judgment against the remaining defendants, Marc Pierre Desgraves IV, Charles Alexander Elliott, and Insulinic of Hawaii LLC, (collectively “Remaining Defendants”) regarding the liability of the Remaining Defendants for trade secret misappropriation, trademark infringement, and unfair competition. The court considered the pleadings and Plaintiffs’ summary judgment and granted Plaintiffs’ summary judgment against the Remaining Defendants regarding liability for trade secret misappropriation, trademark infringement, and unfair competition. The court also granted Plaintiffs’ summary judgment against the Remaining Defendants regarding damages. United States District Court Southern District of Texas ENTERED May 14, 2025 Nathan Ochsner, Clerk Case 4:22-cv-03062 Document 231 Filed on 05/14/25 in TXSD Page 1 of 8 2 The court has considered the pleadings and Plaintiffs’ proposed Final Judgment, and finds that it has subject matter and personal jurisdiction over this action, Plaintiffs, and the Remaining Defendants. The court also finds that venue is proper in the Southern District of Texas. The court incorporates by reference its findings set forth in its Order Granting Stipulated Judgment and Permanent Injunction (Docket Entry No. 212) and Memorandum and Opinion and granting Plaintiffs’ summary judgment against the Remaining Defendants, (Docket Entry Nos. 221, 222). The court makes the following additional findings as to Plaintiffs’ claims for trade secret misappropriation against the Remaining Defendants: a. The Remaining Defendants were given a license to Plaintiffs’ Trade Secrets, which was revoked by Plaintiffs as a result of the actions of the Remaining Defendants in their improper use thereof. Following this revocation, the Remaining Defendants continued to use, and continue to use, Plaintiffs’ Trade Secrets without such authority. b. Plaintiffs have suffered lost profits because of the misappropriation of their Trade Secrets by the Remaining Defendants. Plaintiffs would have gained said profits but for the misappropriation in the competing businesses of the Remaining Defendants. c. The misappropriation of Plaintiffs’ Trade Secrets by Remaining Defendants was willful and malicious, and Plaintiffs are entitled to an award of exemplary damages in an amount equal to twice the award of any other monetary damages under 18 U.S.C. § 1836(b)(3)(C) and reasonable attorney’s fees in this action under 18 U.S.C. § 1836(b)(3)(D). The court makes the following additional findings as to Plaintiffs’ claims for trademark infringement and unfair competition against the Remaining Defendants: Case 4:22-cv-03062 Document 231 Filed on 05/14/25 in TXSD Page 2 of 8 3 a. Plaintiffs have suffered lost profits because of the infringement of Plaintiffs’ Trademarks by the Remaining Defendants, wherein Plaintiffs would have gained said profits but for the infringement in the competing businesses of the Remaining Defendants. b. The nature of the relationship between Plaintiffs and the Remaining Defendants and the fact that Plaintiffs and the Remaining Defendants are direct competitors, the lost profits of Plaintiffs are directly measurable, in part, by the profits gained by the Remaining Defendants. c. The Remaining Defendants were given a license to Plaintiffs’ Trademarks, which was revoked by Plaintiffs as a result of the actions of the Remaining Defendants in their improper use thereof. Following this revocation, the Remaining Defendants continued to use, and continue to use, Plaintiffs’ Trademarks without such authority. d. Plaintiffs possess a high reputation and goodwill in their field, including because of the technologies they developed. This reputation and goodwill are highly important to Plaintiffs, including because they are a market leader and have been required to, and continue to be required to, put forth efforts to counteract the infringement and misrepresentations of the Remaining Defendants. e. Plaintiffs have suffered loss of business, including loss of additional past and future licensees and patients, because of the Remaining Defendants’ unauthorized use of Plaintiffs’ Trademarks. f. The misappropriation of Plaintiffs’ Trademarks by Remaining Defendants was willful and malicious, and Plaintiffs are entitled to an award of exemplar damages in an amount equal to twice the award of any other monetary damages pursuant to Tex. Civ. Prac. & Case 4:22-cv-03062 Document 231 Filed on 05/14/25 in TXSD Page 3 of 8 4 Rem. Code § 134A.004 and reasonable attorney’s fees in this action pursuant to Tex. Civ. Prac. & Rem. Code § 134A.005. g. The Remaining Defendants’ use of Plaintiffs’ Trademarks in connection with the competing businesses of the Remaining Defendants was done with deliberate, intentional, willful, and malicious intent of the Remaining Defendants. h. There was actual confusion by consumers due to the infringing use of Plaintiffs’ Trademarks by the Remaining Defendants, resulting in the diversion of sales from Plaintiffs to the Remaining Defendants. i. As a result of the acts of the Remaining Defendants in both pre-suit infringement and post-suit infringement, this case is exceptional and stands out from other similar cases. Judgment is entered in favor of Plaintiffs and against the Remaining Defendants both individually and as joint and severally liable defendants for Plaintiffs’ trade secret misappropriation, trademark infringement, and unfair competition claims. The Remaining Defendants, and their respective officers, directors, agents, parents, subsidiaries, affiliates, successors, assigns, and each of them, and upon those persons in active conceit or participation with them, who receive actual notice of this Final Judgment and Permanent Injunction by personal service or otherwise, are immediately and permanently enjoined and restrained from doing any of the following without written authorization from Plaintiffs: a. Using any of the knowledge, information, training, or materials taught, delivered, described, or otherwise imparted from Plaintiffs, in whole or in part, as part of any medical procedure, treatment, therapeutic modality, or otherwise; Case 4:22-cv-03062 Document 231 Filed on 05/14/25 in TXSD Page 4 of 8 5 b. Practicing Plaintiffs’ propriety method of insulin resensitization, the microburst insulin infusion modality, or any other form of exogenous intravenous insulin infusion designed to treat diabetes or other metabolic disorders; c. Disclosing Plaintiffs’ Trade Secrets, including their confidential business contacts and their specialized medical training, including their training modules, videos, and handbooks, and methods of conducting their business for Plaintiffs’ proprietary method of insulin resensitization for the treatment of diabetes to any person or entity in the United States; d. Representing, by any means whatsoever, that any products manufactured, distributed, advertised, offered or sold by the Remaining Defendants are Plaintiffs’ products or vice versa, and from otherwise acting in a way likely to cause confusion, mistake, or deception on the part of purchasers or consumers as to the origin or sponsorship of such products; e. Using Plaintiffs’ Trademarks or any confusingly similar derivative thereof, in any form, in connection with the promotion of goods and/or services or as a tradename, service mark, or logo in any such manner that is likely to cause consumer confusion, in a manner disparaging to Plaintiffs, or in a manner that would otherwise unfairly compete with Plaintiffs’ trade or business; and f. Using any internet domain or other social media address that includes any of Plaintiffs’ Trademarks or any confusingly similar derivation. Promptly, and in compliance with the injunction, the Remaining Defendants must cooperate with Plaintiffs to transfer any such domain name to Plaintiffs’ control, and shall terminate the use of any other similar domains it holds as well as any other social media address making use of Plaintiffs’ Trademarks or any derivation thereof. Case 4:22-cv-03062 Document 231 Filed on 05/14/25 in TXSD Page 5 of 8 6 Plaintiffs are entitled to the following damages for its trade secret misappropriation claims against the Remaining Defendants: a.

Based on the foregoing, the total amount awarded to Plaintiffs against the Remaining Defendants is $16,771,973.71, broken down as follows: a. $9,088,814.94 in damages comprising Plaintiffs’ lost profits and disgorgement of the profits of the Remaining Defendants; b. $6,000.000.00 in exemplary damages; c. $683,330.98 in attorneys’ fees; d. $2,154.00 in costs; and e. $997,673.79 in prejudgment interest. Plaintiffs’ claims against the Remaining Defendants are dismissed with prejudice. However, the Remaining Defendants are hereby bound to the terms of the injunction provided herein, under Case 4:22-cv-03062 Document 231 Filed on 05/14/25 in TXSD Page 7 of 8 8 Federal Rule of Civil Procedure 65(d)(2)(C). All claims, defenses, and issues in this action between Plaintiffs and the Remaining Defendants are finally resolved by this Final Judgment and Permanent Injunction, thus disposing of all of Plaintiffs’ claims. No security shall be required with respect to the entry of any of the provisions of this Final Judgment and Permanent Injunction. If any of the Remaining Defendants breaches any terms of the Final Judgment and Permanent Injunction, then Plaintiffs shall be entitled to recover their reasonable attorneys’ fees and costs incurred in seeking enforcement of the Final Judgment and Permanent Injunction. This Court shall retain continuing jurisdiction over the parties and this action for purposes of enforcing or adjudicating claims of violations of this Final Judgment and Permanent Injunction, and any motion or application seeking its enforcement shall be directed to this Court.”

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.

Cited in actionSeptember 8, 2022

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.

Freedom to operate

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.

Strategic implications

What 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.
