Strati Sakellariou-Witt

Partner, Brussels



Strati advises on European competition law and general European Union law questions. She represents clients in merger control reviews, abuse of dominance and cartel proceedings. She has advised companies active in a broad range of industries, including IT, telecommunications, consumer goods, consumer electronics, pharmaceuticals, energy, chemicals, oil & gas, and transport.

She has represented clients before the European Commission in Phase I and Phase II merger control reviews, and has comprehensive experience in representing companies in in-depth investigations which include negotiation of divestitures.

Strati has represented clients in cartel investigations before the European Commission and on appeal in leading cases before the EU courts, including: 'Toshiba v Commission' (gas insulated switchgear); 'Chalkor v Commission' (copper plumbing tubes); 'Toshiba v Commission' (power transformers); and 'Toshiba v Úřad pro ochranu hospodářské soutěže' (ne bis in idem/parallel cartel investigations). Given the global nature of alleged cartel infringements, she has also advised, together with local counsel, clients in multinational cartel proceedings before the Czech, Slovak, Hungarian and Israeli authorities and courts.

Her practice also focuses on abuse of dominance proceedings before the European Commission as well as the Greek and Cypriot competition authorities and courts and has represented clients in relation to different types of conduct, including rebates (soft drinks, milk, semiconductors), excessive pricing (car rentals, FRAND licensing), refusal to supply, margin squeeze (telecoms).

She has particular expertise in pharmaceuticals and life sciences, where she advises clients on competition law questions, including distribution, rebates, generic and biosimilar entry. She has also successfully represented major pharmaceutical companies in abuse of dominance court proceedings in relation to parallel trade of pharmaceuticals in Greece. In addition, Strati has experience in a number of EU regulatory law questions, notably in pharmaceuticals, biotech and other life sciences sectors. She writes on a regular basis on a broad range of life sciences issues and sits on the editorial board of a quarterly newsletter produced for a multinational pharmaceutical company.

Strati advises regularly on questions of EU competition compliance and has conducted mock dawn raids for major international companies. Her secondment to a multinational conglomerate corporation, where she assisted the European Chief Compliance Officer on competition law compliance issues across Europe, provided her with invaluable insight from an industry perspective.
