Coronaviruses are a group of RNA viruses, which cause diseases in humans. The emergence of COVID-19, has caused a global pandemic. It is focused on developing an effective therapeutic strategy against COVID-19. To better understand the development and evolution of therapeutic strategies against coronaviruses, we conducted US granted patents analysis. The results showed vaccines played a leading role in therapies against coronaviruses. Both attenuated vaccines and recombinant genetic vaccines were very important approaches in vaccine development against coronaviruses. It is not a rapid approach to develop peptide drugs against COVID-19 or future novel coronaviruses. The study was the first one to show the development and evolution in therapeutic strategies against coronaviruses based on patent insight. The present study provides a new insight into the development of therapeutic strategies against coronaviruses.
