The acquisition and use of industrial property titles (patents, trademarks, drawings & models) require regulation through contracts.
A sales (or transfer) contract allows the holder of the title to transfer his rights to a third party. This transfer can be either total or partial. It can for example be limited to a certain territory. In terms of patents, the transfer can be limited to certain determined industrial applications, or be limited to certain geographical territories. In terms of trademarks, the transfer may cover only certain products or certain services.
A license (or transfer) contract allows the holder to not use his industrial property title directly. He will authorize a third party to use this title in exchange for the payment of fees (or royalties). The operating license can be granted exclusively (to a single third party) or simply (to several third parties), be limited to a manufacture, marketing or distribution, for a determined duration, over a precise geographical territory, etc.
Clauses that are poorly studied, poorly written or in contradiction with the law, can give rise to legal disputes and unnecessary expense.
In addition, in order to be opposable to third parties, certain contracts (transfers and licenses in particular) must be listed in the official Registries. These registrations involve strict administrative formalities, which generally become complex when they take place abroad.
