The UK Competition Appeal Tribunal (CAT) has delivered a closely watched judgment certifying an opt-out collective proceedings order (CPO) against Valve Corporation, clearing the way for a landmark competition claim to proceed on behalf of millions of UK consumers. The decision marks another important moment in the evolution of collective actions—and their funding—in the UK.

In its judgment, the CAT approved the application brought by Vicki Shotbolt as class representative, alleging that Valve abused a dominant position in the PC video games market through its operation of the Steam platform. The claim contends that Valve imposed restrictive pricing and distribution practices that inflated prices paid by UK consumers. Valve opposed certification on multiple grounds, including challenges to the suitability of the class representative, the methodology for assessing aggregate damages, and the adequacy of the litigation funding arrangements supporting the claim.

The Tribunal rejected Valve’s objections, finding that the proposed methodology for estimating class-wide loss met the “realistic prospect” threshold required at the certification stage. While Valve criticised the expert evidence as overly theoretical and insufficiently grounded in data, the CAT reiterated that a CPO hearing is not a mini-trial, and that disputes over economic modelling are better resolved at a later merits stage.

Of particular interest to the legal funding market, the CAT also examined the funding structure underpinning the claim. Valve argued that the arrangements raised concerns around control, proportionality, and potential conflicts. The Tribunal disagreed, concluding that the funding terms were sufficiently transparent and that appropriate safeguards were in place to ensure the independence of the class representative and legal team. In doing so, the CAT reaffirmed its now-familiar approach of scrutinising funding without treating third-party finance as inherently problematic.

With certification granted, the case will now proceed as one of the largest opt-out competition claims yet to advance in the UK. For litigation funders, the ruling underscores the CAT’s continued willingness to accommodate complex funding structures in large consumer actions—while signalling that challenges to funding are unlikely to succeed absent clear evidence of abuse or impropriety.

Litigation insurers and third-party funders across Europe are closely monitoring the first case heard by a newly constituted panel of the Unified Patent Court’s Court of Appeal, as the matter could offer early signals on how appellate judges will approach procedural and cost-related issues in the UPC system. The case, Syntorr v. Arthrex, is the inaugural appeal to be considered by the third Court of Appeal panel, making it an important early data point for stakeholders assessing litigation risk in the young court.

An article in JUVE Patent explains that the appeal arises from a dispute over European patent rights and follows contested proceedings at the Court of First Instance. While the substantive patent issues are central to the case, the appeal has attracted particular interest from insurers and funders because of its potential implications for security for costs and the treatment of insurance arrangements in UPC litigation. These questions are of direct relevance to how litigation risk is underwritten and financed, especially in cross-border patent disputes where exposure can be significant.

The establishment of additional appeal panels is itself a sign of the UPC’s increasing caseload, and early rulings from these panels will play a key role in shaping expectations around procedural consistency and predictability. For funders, clarity on whether and how courts scrutinise insurance coverage, funding structures, and security applications is critical when deciding whether to deploy capital into UPC matters. Insurers, meanwhile, are watching closely to see how appellate judges view policy wording, anti-avoidance provisions, and the extent to which coverage can be relied upon to satisfy cost concerns raised by opposing parties.

Although no substantive appellate guidance has yet emerged from this first hearing, the case underscores how closely financial stakeholders are tracking the UPC’s evolution. Even procedural decisions at the appellate level can have downstream effects on pricing, structuring, and appetite for funding complex patent litigation.

For the legal funding industry, the UPC Court of Appeal’s early jurisprudence may soon become a reference point for risk assessment, influencing both underwriting practices and investment strategies in European IP disputes.
