But it is rarely so simple, with the activities of the licensee, a deal that must be of great interest to any savvy licensee, because a licensee of poor or poor performance can lead to a product or service that could have developed a good cash flow being useless, while other competing products dominate the field. In addition, most takers require advice and support from the licensee, so it inevitably involves more than “cashing cheques.” While many inventors dream of conceding their product to a multinational that simply pays a lot of money over time, the average license includes two small businesses that have to work together to succeed in the process. Duration: Many licenses are valid for a specified period of time. This protects the licensee if the value of the license increases or if market conditions change. In addition, applicability is maintained by ensuring that no license goes beyond the duration of the contract. A licensing agreement is an agreement by which a licensee grants another company the right to intangible ownership for a specified period of time and the donor receives a royalty from the taker in return. Intangible property includes patents, inventions, formulas, processes, drawings, copyrights and trademarks.  A licence is granted by one party to another party as part of an agreement between these parties. In the case of a government-issued licence, the licence is obtained by application. In the case of a private party, it is a particular contract, usually in writing (for example. B a lease or other contract). The simplest definition is “a licence is a promise not to file a complaint” because, with the exception of a marriage license (which grants only official recognition of the relationship between the two persons), a licence of the licensed party allows either to engage in illegal and criminal activity without the licence (p.B.
fishing, driving a car or operating a radio or television channel) , to do something that would violate the rights of the licensing company (for example. B make copies of a copyrighted work) that could be sued without the license, the conceded, civil, criminal or both. Normally, the subject of a license is that the licensee is passive and receives only royalties, while the taker participates in the business or development and must be used freely as long as royalties are paid and other criteria are met. Failure to comply with the license agreement by the licensee generally results in the termination of the licence and the payment of damages to the licensee. 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.
