Article 1357: Right to a patent for invention, a useful model or an industrial model

1. The right to a patent for an invention, a useful model or an industrial specimen is originally vested in the author of the invention, a useful model or an industrial design. The grant for an invention, a useful model or an industrial specimen may be transferred to or transferred to another person (the successor) in cases and on grounds established by law, including: 3. Agreement on the exclusion of the right to a patent for an invention, a useful model or an industrial image 4. If the agreement of the parties to the contract on the exclusion of the right to obtain a patent for an invention renders the contract null and void, the non-compliance with the written form must be concluded in writing. There is no other provision for a useful model or industrial model, and the buyer of such right bears the risk of non-patentability.
