Patent activity in the field of graphene microwave path elements GHZ range from the point of view of import independence

Abstract

The patent activity in the field of graphene microwave path elements the GHz range is analyzed from 2004 (the year of graphene discovery) to the present from the point of view of import independence. The articles from SCOPUS and WoS were taken into account in analysis in addition to patents. The search was conducted by countries: Russia, USA, China, India, Great Britain, Germany, France, Italy, Spain, Japan, Iran, Malaysia; by branch of knowledge: technical applications, energy, applications in chemical technology, biotechnology, chemistry, applications in computer technology, applications of mathematics, also materials science and the field of physics and astronomy. The patent research methodology is based on conducting searches through a combination keywords, and IPC indexes. Statistical analysis of patent documents selected because of the search illustrates the main conclusions regarding inventive activity in the research area by IPC indices years of priority, countries.
