Overview
The Challenge
The claimant asserted that he was the original author of a foundational cryptographic protocol and, on that basis, brought proceedings against a group of developers and companies involved in maintaining and building upon open-source software associated with the protocol. The claim raised novel questions about how property and intellectual property law principles apply to decentralised, collaboratively developed software, an area with little established precedent.
The stakes for the defendants were considerable: an adverse finding risked establishing precedent that could have chilled participation in open-source development across the wider digital assets industry, well beyond the specific parties involved in the litigation.
Our Approach
Our Disputes team was instructed because of the firm's experience in complex, technically demanding litigation and our familiarity with the digital assets sector. The case required close collaboration with technical experts to build an evidential record capable of withstanding detailed cross-examination on highly specialised cryptographic and software development concepts, translated into a form the tribunal could assess with confidence.
We ran an extensive disclosure exercise to test the claimant's account of authorship against the contemporaneous technical record, and worked with counsel to develop a case strategy that addressed both the narrow legal questions in dispute and the broader factual narrative underpinning the claim.
The Outcome
The tribunal found decisively in favour of the defendants, rejecting the claimant's case on authorship and ownership in its entirety. The decision was widely reported across the digital assets industry and has since been cited as a reference point in subsequent disputes involving open-source software and digital assets.
