Problem setting. In the conditions of the full-scale war of the Russian Federation against Ukraine, the destroyed infrastructure, the loss of a large part of the raw material bases, the littering of agricultural lands, our state especially needs the implementation of progressive solutions with the aim of rebuilding the economy based on innovation and creating products with high added value. On the other hand, in the context of European integration processes, a comprehensive and rapid adaptation of legal, state, economic, scientific and other elements to the realities of EU functioning is necessary. Thus, there is a need to study the content of deep tech innovations, as a new wave of innovations, defined in the New European Innovation Agenda dated 07.05.2022, as well as the main legal aspects of its practical implementation in Ukraine. analysis of recent researches and publications. Some separate aspects of the issue of deep tech innovations received attention, both by foreign authors, in particular, in the works of O. B. Apodaca, L. Frolund, F. Murray, S. Pamela, A.Swain, and in the works domestic scientists I. Podorychyva, M. Haustov, P. Kartashov and others. At the same time, the issue of deep tech innovations requires a more detailed study as a separate phenomenon, including with the aim of introducing its legal regulation in Ukraine. Purpose of the research is to determine the essence and content of deep tech innovations as a «new wave» of innovations in the European Union, taking into account the scientific approaches proposed by foreign and domestic scientists. In addition, an important goal of the article is to determine the expediency and ways of adapting the main legal aspects of the development and support of such innovations in Ukraine, including in the context of European integration processes in our country. article’s main body. The article is devoted to the study of the legal nature of deep tech innovations, as a new wave of innovations in the world and in the European Union, in particular. The main provisions of the legal regulation of the specified innovations in the EU have been defined. Some scientific approaches of foreign and Ukrainian scientists to understanding the essence, content, and definition of the concept of deep tech innovations are given. An attempt was made to characterize deep tech innovation as a new wave of innovations that are based on advanced science, technology and engineering, are mostly physical products, often combine achievements in the physical, biological and digital spheres and have the potential to provide transformative solutions to global challenges of humanity. The issue of legal regulation of the specified concept in Ukrainian legislative acts has been studied. The main features of innovative processes in Ukraine related to the full-scale invasion of our country are given. The need to implement the main aspects of the legal regulation of the development of deep tech innovations in Ukraine is substantiated, including on the basis of the analysis of the provisions of the Association Agreement between Ukraine and the European Union, the European Atomic Energy Community and their member states, as well as practical expediency. conclusions and prospects for the development. According to the results of the analysis of innovation processes taking place recently, it was established that the surface aspects of deep tech innovations, despite the lack of definition in legislation, are applied in practice, in particular, at the initiative of foreign partners, including the European Union. At the same time, the mentioned concept is relatively new for Ukrainian legal science and not sufficiently studied. At the same time, in our opinion, in order to adapt the provisions of Ukrainian legislation to the EU Acquis, it is advisable to pay attention to the legal regulation of the main aspects of the specified concept.
