| Abstract: |
Artificial intelligence (AI) technology can play a critical role in economic
development, resource conservation, and environmental protection by increasing
efficiency. This study is the first to apply a decomposition framework to
clarify the determinants of AI technology invention. Exploiting data from the
World Intellectual Property Organization, this study clarifies the determining
factors that contribute to AI technology patent publications based on
technology type. Consisting of 13,567 AI technology patents for the 2000-2016
period, our worldwide dataset includes patent publication data from the United
States, Japan, China, Europe, and the Patent Cooperation Treaty (PCT). We find
that priority has shifted from biological- and knowledge-based models to
specific mathematical models and other AI technologies, particularly in the
United States and Japan. Our technology type and country comparison shows that
the characteristics of AI technology patent publication differ among companies
and countries. |
