The Japanese intellectual property landscape continues to evolve rapidly in 2026, with significant developments in AI-related patent examination, Letter of Consent practice for trademarks, and accelerated examination programs. This comprehensive annual report from EVORIX Intellectual Property Law Firm provides foreign IP counsel, in-house IP teams, and IP researchers with the data and analysis needed to navigate Japan's IP system in 2026.
Based on JPO published statistics, our internal data from 500+ foreign client engagements, and direct observation of examination trends, this report covers patent, trademark, and design filings, foreign applicant patterns, JPO performance metrics, and strategic recommendations for the year ahead.
Key Findings — Executive Summary
Japan's IP system in 2026 reflects three major themes: (1) operational stability with steady ~290,000 annual patent filings, (2) increased foreign filer sophistication as more firms leverage PPH and AI-related filings, and (3) regulatory modernization including the 2024 Letter of Consent practice update and ongoing JPO AI integration.
For foreign IP counsel, key takeaways for 2026 include: ensure multi-multi claim restructuring at PCT entry; leverage PPH aggressively when corresponding office allowance exists; consider Letter of Consent strategy proactively in trademark prosecution; and budget for higher annuity costs as Japan annuities scale steeply in later years.
