IP and IT in Luxembourg

Arendt & Medernach

The ‘very knowledgeable and responsive team’ at Arendt & Medernach has the strength-in-depth to handle a wide range of work, running the gamut from large-scale digitalisation projects and the IP due diligence associated with M&A mandates, through to advice on the commercialisation of IPR and unfair competition and product regulation. Data protection-related work remains a key driver for the practice, and aided by practitioners within the Arendt Regulatory and Consulting group (which bridges the gap between legal advice and its practical implementation), the firm has effectively been able to implement robust compliance procedures for clients. Astrid Wagner is ‘very impressive’ and co-heads the team alongside Sophie Wagner-Chartier.

Cyril Pierre-Beausse is specialised in data protection and IT-related work and he continues to represent many financial services entities on their IT outsourcing arrangements. The team is rounded out at partner level by Claire Leonelli, whose wide-ranging practice includes a considerable amount of copyright-related work and large-scale digitisation projects, and Elisabeth Guissart, who is best-known for her data protection expertise. At an associate level, Claire Denoual is recommended.
