In 1977, Patrizio Bertelli set up I.P.I spa to consolidate the production resources that he had built up over the previous ten years, including those of Sir Robert and Granello. In the same year, I.P.I spa obtained an exclusive license from Miuccia Prada to produce and distribute leather goods bearing the Prada brand name. In the following years, the activities of the two families were gradually brought together within a single Group and, in 2003,IPI spa was merged into PRADA spa
