Cross-Jurisdictional Analysis Charts Diverging Rules for Litigation Funding
Third-party litigation funding has grown into a multibillion-dollar force across major legal markets, yet the rules governing it remain strikingly inconsistent from one jurisdiction to the next, according to a new cross-jurisdictional analysis.
As reported by JD Supra, the review — authored by Arthur Coviello, Colin Dunn, and Mark Selwyn of WilmerHale — examines third-party funding across the United States, United Kingdom, Germany, China, and the Unified Patent Court. It notes that funders now manage billions in assets, with an estimated 20% committed to patent litigation, and that the U.S. leads but no longer dominates a market with established industries in the U.K., Germany, and China.
The authors highlight a sharp regulatory divergence. The United States has built a patchwork of state and federal measures, including disclosure requirements, while the U.K., Germany, China, and the UPC have largely declined to adopt comprehensive rules despite voicing similar concerns about conflicts of interest, funder control, and foreign influence.
The analysis catalogs recent developments: at least five bills pending in Congress addressing transparency and national-security concerns, the lingering effects of the U.K.'s 2023 PACCAR decision and the Civil Justice Council's call for "light touch" regulation, the European Commission's November 2025 decision not to adopt proposed funding rules, and the International Trade Commission's recent disclosure proposal. Without mandatory disclosure, the authors argue, judges and parties cannot reliably assess who holds a stake in a case or where potential conflicts may lie.
