Lexing Avocats

Innovative in its organization, management, and quality system (ISO 9001:2015 certified since 1998 in the field of advanced technology law for advisory and litigation services), Lexing has an international presence through the Lexing® Network, which brings together 42 members in 41 countries.

Its positioning—centered on digital and technology law—naturally leads the firm to operate across all advanced technology sectors as they emerge and evolve. In particular, it possesses deep expertise in digital law, IT law, and AI law. By mastering the entire value chain of IT and AI projects, the firm brings a cross-functional and operational edge to its strategic consulting, compliance, contracting, and litigation practices. It intervenes at every milestone: RFP assistance, negotiation, legal project phasing (scoping-design-build-run-maintenance), contract management, escalation and dispute management, court-appointed expert proceedings, and litigation.

Its expertise in these matters is highlighted by its numerous publications and books, including The European AI Act (2025); ChatGPT dans le monde du droit – la cobotique juridique [ChatGPT in the Legal World – Legal Cobotics] (2023); Algorithmes et droit [Algorithms and Law] (2023); Legal Aspects of Artificial Intelligence (2019); Le contract manager [The Contract Manager] (2019); IA, robots et droit [AI, Robots and Law] (2019); Informatique, Télécoms, Internet [IT, Telecoms and the Internet] (2017, 6th ed.).

Its teams are composed of both legal and technical experts: lawyers with a daily practice in AI law, an in-house IT and digital team closely aligned with business needs, and specialized information systems security consultants.

The firm operates two subsidiaries: Lexing Editions, which publishes Planète Robots, the only mainstream magazine entirely dedicated to robotics and artificial intelligence; and Lexing Technologies, which delivers SaaS solutions for GDPR compliance, contract management, risk management, cybersecurity, and other digital governance or regulatory requirements.
