Aperçu du dossier
Les parties
⚖️ Demandeur
A patent assertion entity (PAE) focused on monetizing intellectual property related to computerized ledger systems.
🛡️ Défendeur
A decentralized autonomous organization (DAO) governing the Maker Protocol on the Ethereum blockchain.
Le brevet en cause
This case centered on a single patent covering fundamental computerized ledger architectural elements. Patents are registered with the U.S. Patent and Trademark Office (USPTO) and protect novel and non-obvious inventions.

Le verdict et l'analyse juridique
Résultat
On August 9, 2024, True Return Systems filed a Notice of Voluntary Dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a). Chief Judge Swain directed the Clerk to close the action and terminate all open motions. No damages were awarded. No injunctive relief was granted. The dismissal with prejudice is a final adjudication on the merits — True Return Systems cannot refile this infringement action against MakerDAO based on the same patent and accused conduct.
Analyse stratégique du licenciement
A voluntary dismissal with prejudice after nearly two years of active litigation — with multiple motions still pending — is a significant strategic signal. It typically reflects one or more of the following:
- Unfavorable Claim Construction Positioning: If MakerDAO’s defense team successfully reframed the scope of patent claims during Markman proceedings or briefing, the plaintiff may have faced an infringement theory that no longer survived scrutiny.
- Validity Pressure: Perkins Coie’s defense team likely mounted prior art and invalidity challenges. The patent’s broad architectural claims risk invalidation under 35 U.S.C. § 101 (patent-eligible subject matter) or obviousness grounds.
- Defendant Identification Complexity: MakerDAO’s decentralized structure raises novel jurisdictional and party identification questions. Establishing proper service, legal standing, and damages attribution against a DAO presents meaningful litigation obstacles.
- Economic Calculus: With a well-resourced defense team and no clear path to damages or injunction, continued litigation costs may have outweighed projected recovery.

U.S. Patent No. 10,025,797 B1 (Application No. 15/923,317), covering a method and system for separating storage and processing functions in a computerized ledger.
True Return Systems filed a voluntary dismissal with prejudice on August 9, 2024. No court ruling on the merits was issued; the dismissal may reflect unfavorable claim construction positioning, validity risk, or strategic economic considerations.
It highlights the challenges of asserting software-architecture patents against decentralized protocols and reinforces the importance of § 101 eligibility and claim construction strategy in blockchain IP disputes.
