Get a lawyer who has expertise in licensing agreements. These agreements are complex and situation-specific. Many lawyers know how to build a general contract, but they cannot know the details of licensing agreements. An intellectual property lawyer could be a good place to start. However, the artistic licence is not related to the aforementioned licence. It is an understatement, freedom of expression, the ability to make the subject more attractive or more attractive, by fictionalizing a part of the subject. Patent licenses have been studied in formal business models in the field of industrial organization. In particular, Katz and Shapiro (1986) studied the optimal licensing strategy of a research laboratory sold to competing companies in the product market.  It appears that the licensee`s incentives to develop innovation may be exaggerated (compared to the social protection solution), while the licensee`s incentives to disseminate innovation are generally too low. Subsequently, the pioneering work of Katz and Shapiro (1986) was extended in several directions. For example, Bhattacharya, Glazer and Sappington (1992) have taken into account the fact that licensed companies need to invest more to develop marketable products.  Schmitz (2002, 2007) has shown that due to negative selection or moral risk, asymmetric information can lead the research laboratory to sell more licenses than would be the case for complete information.   Antelo and Sampayo (2017) studied the optimal number of licenses in a signalling model.
 Subsidiary license. The licensee may be granted the right to authorize someone to manufacture or sell their products. This depends on the specific terms of the license agreement. In the context of a pure licensing agreement, the licensee may, on its terms and under the common law, terminate the contract as it sees fit and without reason, unless it is linked to an interest or rendered irrevocable by contract. An interest-related licence cannot be revoked by the licensee without liability and potential damage. In the event that a licence is related to an interest, the licensee must give the licensee a reasonable period of time to withdraw that interest from the property prior to termination. Since a licence does not confer any interest on the licensee, the licence is terminated in the event of the sale of the property and cannot be imposed on the new owners of that property. In addition, the death of the licensee or licensee will terminate the contract.
