Patent law, which arose at the beginning of the industrial revolution and protects the rights of the patent holder solely on the territory of patenting, does not apply to inventions used in outer space. Space is not included in any patenting territory. It is necessary on a new basis to form the space law on the protection of innovative solutions, which will take into account the uncertain time between the filing of an application for an invention and its first use in space. Now it often exceeds the generally accepted period of validity of patents. For space patents, it is advisable to establish their validity for at least 50 years from the date of first use. All outer space, including all objects located in it, is proposed to be declared a single patent territory. It is necessary to exclude duties on the maintenance of patents used in space flights, if they are used only by the developer or are transferred to them for free leasing.

Abstract This paper addresses a finite-time regulation problem for time-varying nonlinear systems in p-normal form. This class of time-varying systems includes a well-known lower-triangular system and a chain of power integrator systems as special cases. No growth condition on time-varying uncertainties is imposed. The control law can guarantee that all closed-loop trajectories are bounded and well defined. Furthermore, all states converge to zero in finite time.

This paper considers the robust stabilization problem for interval plants with parametric uncertainty and uncertain time-delay based on the value set characterization of closed-loop control systems and the zero exclusion principle. Using Kharitonov’s polynomials, it is possible to establish a sufficient condition to guarantee the robust stability property. This condition allows us to solve the control synthesis problem using conditions similar to those established in the loopshaping technique and to parameterize the controllers using stable polynomials constructed from classical orthogonal polynomials.
