Dr. Bertold Bär-Bouyssière, LL.M., is one of the leading practitioners of competition law in Brussels and Germany. Bertold has more than 20 years of experience in the field. A partner with DLA Piper’s Brussels and German offices, Bertold is a Fulbright alumnus and admitted to the New York, German and Brussels bars. Bertold currently heads the EU Competition team in Brussels and also has responsibilities as Elected Member of DLA Piper's International Board. Since 2017, Bertold serves as Elected Co-Chair of AmChamEU's Competition Policy Committee.

Bertold is recommended since 2004 in Chambers' The World's Leading Lawyers and Legal 500 as a leading expert for EU Competition and State aid (subsidies) law, with a special praise of his talent for delivering time and cost-efficient high-quality work. Clients describe him as a "very efficient, proactive and business-oriented lawyer who always makes himself available - brilliant." (Chambers 2017).

Together with other partners and his team, Bertold advises at the forefront of competition law developments. With a large team of lawyers from several offices he currently represents clients in the EU's and CMA's first ever investigations into "reverse patent settlements" in the pharmaceutical sector ("pay-for delay"), and he is currently advising several international clients, institutional stakeholders and foreign Governments in connection with the European Commission's investigations into tax rulings in EU Member States. Over the years, Bertold has gained extensive experience in the application of competition rules in a large variety of industry sectors including chemicals, crop protection, petrochemicals, pharmaceuticals, medical devices, gas, electricity, steel, motor vehicles, automotive components, construction equipment, cable television & multimedia, telecommunications, aerospace, satellite launching, tourism, air transport, defence equipment, online gaming, shipbuilding, food processing, fuel card services, financial services and luxury watches. He is also well connected with the political EU stakeholders in Brussels.

Giving back to the community is very important to Bertold, who manages DLA Piper's worldwide legal support to EURORDIS, the European Organization for Rare Diseases. Together with his family, he has been sponsoring the education of several children in Ethiopia for more than fifteen years.

Bertold provides services to DLA Piper UK LLP through a civil company under the form of a personal liability.
