Abstract

Silver nanoparticles gained much attention in research and development because of its unique physical, chemical and biological properties that can be applied in various areas of applications. While several paper have been published, there has been no formal evaluation of its global patent landscape. This study explores the silver nanoparticles diverse patent applications by analyzing a data set of 20,778 patents by 54 countries from the start of silver nanoparticles patent publication to the year 2021. These is done by categorizing patents and with the used of network statistical analysis. Patent documents was searched using AccliamIP database with proper set of keyword used. Silver nanoparticles showed diverse areas of its utilization. Synthesis methods like biological, sol-gel and microwave assisted synthesis are the most widely used. Heat map indicated that most prolific countries were China and USA. International companies like GENENTECH INC and 3M INNOVATIVE PROPERTIES showed highest interest on this nanomaterial. Moreover, Philippines have 6 silver nanoparticles patents mainly in the field of Human Necessities.
