早期審査 — Accelerated Examination Eligibility

Target: First Office Action in 2 months · Typical total pendency 6–9 months

Japan's 早期審査 (Hayaki Shinsa) program grants examination priority when at least one eligibility criterion is met. Unlike PCT or Track One programs, Japan's accelerated exam is free of additional fees.

Applicant is already working (manufacturing/selling) the invention in Japan

A third party is (or is likely to be) implementing the invention in Japan

PCT application with Japan national phase and IPER already issued

Invention contributes to reducing environmental burden (green tech track)

SME, individual inventor, or university with priority examination eligibility

Tick at least one criterion to confirm eligibility.

6-Month Grace Period (Art. 30 JPL): Japan allows a 6-month grace period from the applicant's own public disclosure (publications, academic presentations, exhibitions). File Form 30 declaration with the application or within 30 days. Internet disclosures and sales generally qualify. Unlike China, Japan's grace period covers the applicant's own disclosures broadly.
