Sylvain Boyer filed a complaint against COJOP and a communications agency for favoritism, illegal taking of interests, counterfeiting and receiving stolen goods. The complaint is currently being analyzed by the National Financial Prosecutor's Office.

The designer believes he was fraudulently sidelined in favor of the W Coran agency, under the pretext of a new, expanded market. The latter's lawyer, Julien Guinot-Delery, indicated that he “refutes all of the manifestly unjustified grievances formulated by Sylvain Girler and his company Royalties” The Co-founders of W Conran, Gilles Deléris and Denis Gancel, described the complaint as a “blackmail strategy, motivated by unacceptable financial maneuvers” The Organizing Committee is currently the subject of four separate financial investigations, relating in particular to its remuneration or to suspicions of favoritism during the award of contracts. In 2019, SylvainBoyer won a contract dedicated to the design of the Olympic emblem.
