Analysis
What this data actually tells you
The Japan Patent Office (JPO) recorded 358,317 total patent applications in 2025, a 17% year-on-year increase notably higher than any of the past 10 years, driven partly by an unusual surge of over 82,000 applications in December 2025 alone; Japanese entities filed 80.3% of all applications, with US, Chinese, and Korean entities filing most of the remainder.
No dedicated broader sectoral statistics (employment, revenue) for this NACE section beyond JPO patent-filing data were located in this research. Counterparties verify a professional, scientific, or technical-services counterparty’s actual current patent-filing activity and scale directly.
