A turbo engine is used to improve engine volumetric efficiency by using the energy of exhaust gas with a device such as a turbocharger. Recently, it has been attracting attention as a solution for responding to environmental issues such as exhaust gas regulation, and its use is being expanded to gasoline and CNG engines as well as diesel engines. However, as electric and hydrogen vehicles enter the automotive market more rapidly, traditional turbo engines also confront many challenges. In this paper, to examine the current status and prospects of the turbo engine, we analyze the related patents in the turbo engine field applied to patent offices in seven major countries, including Korea, USA, China, Japan, Germany, France, and the European Union Patent Office, and analyze the patent application trend. Using ‘the pie’ system of Korea Institute of Science and Technology Information (KISTI), family patents were refined, patent application trends were diagnosed, and the technology and market competitiveness of major applicants were compared and analyzed. Even within the turbo engine market, where traditional automakers and turbocharger manufacturer participate, it was possible to examine the dynamic changes in the market through the analysis of technology and market competitiveness. The main companies leading the technology and market aspects and the companies specialized in the technology and market aspects were observed.

A non-pneumatic tire (NPT), unlike a pneumatic tire, is a tire that acts as air pressure with spokes, and has the advantage of not requiring maintenance of air pressure and the risk of puncture of the pneumatic tire. Recently, many technological advances are taking place in non-pneumatic tire (NPT) using artificial intelligence technology, and non-pneumatic tire manufacturers are actively conducting research and development. Here, in order to compare and analyze the technological competitiveness of major patent applicants, non-pneumatic tire-related patents that have been applied for Japan, the United States, China, Korea, Germany, France, and the European Union Patent Office are reviewed through the patent applications of global tire manufacturers.
