Claudio Mereu

Claudio Mereu is a partner in our Brussels office, where he heads the EU Regulatory Group and the firm's Life Sciences Group.

His practice focuses on European Union law, with an emphasis on the chemicals (REACH), pesticides, biocides and life sciences industry sectors, as well as other regulated industries including medical devices, pharmaceuticals, cosmetics, toys, electrical and electronic equipment, and fuel additives (including devising lobbying strategies and general compliance issues).

Claudio advises on regulatory compliance issues, task force/consortia formation (under pesticides, biocides and REACH), product defence strategies and product circulation across the European Union.

He handles product approval processes in the EU, related litigation before European courts, national courts and WTO panels, and counsels companies on a wide range of business law and antitrust matters relating to their international agreements and commercial presence in Europe (distribution agreements, supply contracts, letters of access, data compensation agreements, R&D joint ventures, etc.).

His expertise covers all aspects of product regulations and restrictions (including notification, data protection, mutual recognition, classification & labelling, marketing and use restrictions, parallel imports, environmental liability, product recalls and data compensation negotiations, amongst others). In the life sciences sector, Claudio advises on a wide range of issues relating to the importation, regulation and sale of medical devices, pharmaceuticals, GMOs, novel food, food supplements and food contact materials, for which he has been recommended for several years by “Global Counsel - Life Science Industry Report”.

He regularly represents chemical companies before the European Institutions, Member State authorities, Scientific Committees, and the European Courts. He was involved in the first case of data sharing arbitration in Italy and in a case of alleged abuse of dominant position on pesticides markets, both of which he successfully resolved on behalf of his clients. He also obtained interim relief measures in a landmark case against a product restriction decided by the European Commission. Since many years Claudio is being regularly invited to major international conferences as an expert speaker and panellist on pesticides/chemicals and is highly recommended by Legal 500, Chambers Europe and the Life Sciences Industry Report.

Claudio graduated in law at the University of Modena (Italy), where he specialised in European Community law. He studied one year of law and economics at the University of Leicester (UK) and obtained his postgraduate diploma in European Community law at King's College (University of London). He is admitted to practice in Belgium as avocat and is a member of the Rome bar.

He is fluent in English, French, Spanish and Italian.
