Research
I specialize in intellectual property law, with a particular focus on the impact of emerging digital technologies, including generaive AI, on legal systems. Through a comparative analysis of intellectual property law in Japan and China, I examine legal issues concerning copyright, trademarks, unfair competition, and data use in the contexts of generative AI and the metaverse, as well as the licensing of standard-essential patents (SEPs) and related dispute resolution mechanisms. My research aims to contribute to the develpoment of a legal framework that balances technological innovation with the appropriate protection and use of intellectual property, while also applying its findings to education and practical implementation.
