Predatory pricing is a form of abuse of a dominant position, which is prohibited by European and national competition law. It is an anti-competitive strategy aimed at excluding competitors from the market in order to maintain or strengthen the dominant position of the predator. The harmfulness of predatory pricing is reflected in the negative effects on consumers, market structure, innovation, and the variety and quality of products. For this reason, predatory pricing has been the subject of study by numerous legal and economic theorists. In 2019, the European Commission adopted the Qualcomm desicison, which is the first decision establishing the abuse of a dominant position by predatory pricing since 2003. The Commission's conclusion is that Qualcomm abused its dominant position on the market of chipsets for mobile devices by selling a certain amount of products at predatory price levels to two of its key customers, all with the intent of excluding its main competitor from the market. This paper elaborates in detail the concept of predatory pricing in general, and then analyzes the Commission's decision in the Qualcomm case and its impact on the further development of European law.
