Determining ownership of an invention is a fundamental first step in securing patent rights and commercializing technology. In Japan, the legal framework for invention ownership starts with a clear principle but quickly delves into complexities, especially concerning inventions made by employees.

For businesses operating in or engaging with Japan, a clear understanding of its intellectual property (IP) landscape is crucial.
