152The Court must reject the argument that the applicant sold Copigraph with its archives and therefore allegedly no longer had the means to defend itself. First, it was for the applicant to ensure, in the circumstances of the sale of Copigraph, to keep in its own books or records or by any other means, such as a right of access to the transferred archives, the information that would enable it to retrace the activities of its subsidiary, in order to have the necessary evidence to be able to defend itself in the event of judicial or administrative actions (see, to that effect, Hoechst v Commission, paragraph 45 above, paragraph 171). Secondly, to accept that argument would undermine the Commission’s very right to pursue a parent company after the sale of its subsidiary.
