Abstract
Smart cities thrive on supporting digital technology innovation of applications and patent protection in the entrepreneurial ecosystem. This research aimed to explore the significant trends in patents related to smart city applications worldwide. The researcher conducted a patent landscape analysis using 22,655 patent materials from the Lens.org database. The study's findings indicate that the number of patents for applications related to smart cities is rising annually. There is an opportunity to use innovations in smart city applications without having to pay royalties by using 1,443 patents that have been discontinued. With seven companies, American corporations have most of the patents for applications in smart cities. The most productive individual investor was Kim Soenghun from Korea, with 946 patents. The electricity (H), physics (G), and new technological developments (Y) patent sections dominate patents related to smart city applications. There were 11,903 simple family patents for smart city applications in seven country jurisdictions; the United States occupied the highest region.
