Attorneys who build software — and litigate it

Software & Technology Litigation

When software projects, SaaS relationships, or AI deployments end in litigation, the disputes are technically dense and document-heavy. Our attorneys build software and ship AI systems — so when a software dispute, source-code claim, or trade-secret case lands on our desk, we read the codebase, not just the contract.

Software & SaaS Disputes

Software projects fail in technically complex ways, and the resulting litigation requires counsel who can read both the contract and the code. We litigate claims involving IP ownership of custom-developed software, source-code escrow disputes, API and integration failures, SaaS service-level breaches, software warranty claims, and disputes over deliverables on stalled or abandoned development engagements. We handle these matters in Cook County Circuit Court and the Northern District of Illinois, and in courts across the country where the contract or the conduct reaches.

Software Trade Secret Litigation

Source code, training data, model weights, architecture documents, and internal tooling are among the most valuable assets a software company owns — and the most vulnerable when a co-founder leaves, an engineer joins a competitor, or a vendor exits with a copy of the repository. We litigate software trade secret claims under the federal Defend Trade Secrets Act (DTSA) and the Illinois Trade Secrets Act (765 ILCS 1065), including emergency injunctive relief, expedited discovery into devices and repositories, and forensic evidence preservation. As part of a trial team at an international law firm, our attorneys helped secure a $66M verdict in a trade secret case involving complex manufacturing technology.

AI & Machine Learning Litigation

AI is a rapidly developing source of new IP disputes. We handle litigation involving training-data copyright and trade-secret claims, AI output infringement and ownership disputes, model-weight misappropriation, allegations of model copying, and IP-allocation fights between AI vendors and their customers. We also litigate right-of-publicity and unfair competition claims arising from AI-generated likenesses and deepfakes — overlap that often draws on both software-litigation and traditional IP-litigation tools.

Open Source License Enforcement & Disputes

Open-source software is everywhere, and so are the disputes that arise when copyleft obligations are ignored. We litigate GPL and AGPL enforcement actions, copyleft compliance disputes, and downstream license-violation claims, as well as defending companies accused of failing to meet attribution, source-availability, or share-alike requirements. These cases sit at the intersection of copyright law and software architecture, where understanding the actual code matters as much as understanding the license.
