RT Journal Article T1 Abuse of Dominant Position, Effective Judicial Protection and Abuse of Procedure A1 De-Vivero-de-Porras, María del Carmen A1 Sanjuán-Muñoz, Enrique K1 Competencia económica desleal K1 Industria farmacéutica K1 Medicamentos -- Legislación K1 Medicamentos -- Derecho K1 Derecho mercantil K1 Comercio -- Regulación K1 Patentes -- Derecho AB On October 21, 2022, the Spanish Competition Agency (CNMC) sanctioned the North American pharmaceutical company Merck Sharp & Dohme for abuse of a dominant position. The practice for which it was finally sanctioned consisted of the adoption of a strategy aimed at delaying and making it difficult for another company to enter the Spanish medicines market in order to protect sales for a product marketed exclusively by that company and for which had a patent. This paper analyzes this resolution in an attempt to delimit the difference between the legitimate exercise of the right to effective judicial protection and its abuse.
