Xu, C.M. and Zhu, D.Z., 2020. The development of marine drugs: A research based on patent analysis. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 271–276. Coconut Creek (Florida), ISSN 0749-0208.

To study the condition of marine drugs, optimize the management of research and increase the efficiency of development, in this article the patents about marine drugs from all over the world have been analyzed qualitatively based on Patsnap search and analysis platform. A valuable reference for the development of Chinese marine drugs industry is expected by using patent bibliomatrics and statistical method, and the aspects of technology development trend, geographical distribution, technical branches and patent value are taken into account. The present key technologies are controlled by European and American Countries, and are also distributed in major markets around the world. The market in China is advantageous for active innovation and commercialization, but is lack of key technology and long-term layout. In this area the organic component pharmaceutical preparation has become the technical hot point, while gene engineering with a few achievements is in need of advanced development.
