Calypso license management is ensured by Innovatron, who in the nineties co-financed the R&D development of the Calypso solution. RATP, the proprietary of the Calypso patents, has delegated an exclusive mandate of gesture of Calypso license to Innovatron, who is consequently the only one able to negotiate and sell a license to a manufacturer. In counterpart of this exclusivity, Innovatron has no authorization to manufacture whatever Calypso product. In consequence, for Innovatron, the return on investment is ensured only through the selling of license, which guarantees the users that they will benefit from the maximum number of manufacturers in competition for buying their Calypso products. All the Calypso licensees benefit from the same conditions and fees, ensuring a true and loyal competition between them in tendering process.
Regarding the costs of the Calypso products, the fees linked to the Calypso license have no impact, or a favorable one: in all products, one part of the selling cost is always dedicated to the return on investment of the R&D program of the manufacturer who designed this product. For a Calypso product, this part of the cost is shared between all the licensees through the Calypso fee, which represent an amount less important than in the case of a product of a single manufacturer (there is only one R&D cost for all manufacturers selling Calypso products).
