The purpose of this scientific article is to justify the need to create a new law of intellectual property, which would protect and defence the rights of the rationalizers and successors of the creator of the rationalization proposal. It has been noted that lately, some scientists have underestimated the importance of our chosen to study the intellectual property object. It is emphasized that it is worth studying the experience of legal regulation of innovation in the production of economically developed countries, in particular, Germany. It is emphasized that during the post -war reconstruction of Ukraine and the creation of an innovative economy, stimulating the development of rationalization is an effective lever of the above process. On the basis of the analysis of the current legal acts and scientific achievements of modern scientists, an attempt was made to find out the main shortcomings of the modern regulatory framework and the determination of ways of overcoming them. It is noted that in the future law it is necessary to pay special attention to the conceptual apparatus, the conditions of protection of the rationalization proposal, the personal non - property rights of the rationalizer, his property rights and defence rights of the successors. Since the rationalizer is usually an employee, it is suggested to think about providing him with greater preferences in labor law compared to current standards. It is emphasized that it is necessary to create the conditions for realization of the ability to register a transformed rationalization proposal into a utility model or invention. It is also necessary to stimulate employers to quickly introduce the specified intellectual property object into production. Therefore, in the future, the law must be laid by mechanisms of such incentives. In the rules for the protection of the rights of the subjects of the rationalization proposal, it will be right to specify the main offenses and to provide responsibility for seeming co - authorship.
