Looking for a clear, practical guide to trademark examination in Japan?

This article walks you through who examines your application at the Japan Patent Office (JPO), what legal grounds are reviewed (distinctiveness and conflicts), typical JPO timelines.

It’s written for foreign applicants and in-house counsel planning filings in Japan.

Quick Summary

  • Who examines: JPO examiners (after a brief formalities check) conduct a full substantive examination.
  • What they check: Absolute grounds (e.g., lack of distinctiveness under Article 3 of the Japanese Trademark Act) and relative grounds (conflicts with earlier marks under Article 4).
  • Timeline: Most cases see a first action in about 5–8 months from filing; total time to registration is commonly 6–12 months (can be shorter/longer depending on backlog).
  • If refused: You’ll receive a Notice of Reasons for Refusal. You may amend goods/services, submit arguments, and if needed appeal a final refusal.
  • Foreign applicants: If you don’t have a Japanese address/office, a Benrishi (Japanese trademark attorney) is legally required to act before the JPO.

1) Who examines your application?

After filing, your application first passes a formalities (form) check. Then a JPO examiner (appointed under Trademark Act Art. 14) performs the substantive examination to decide whether your mark can be registered.

Examination follows the JPO’s published Examination Guidelines, which promote consistent, predictable decisions.

2) What does the JPO examine? (Legal grounds you should know)

A. Absolute grounds (distinctiveness) — Trademark Act Article 3

The examiner asks: Can this sign indicate a single source?
Common refusal bases include:

  • Generic/common names of goods/services
  • Customary terms in trade
  • Quality/description only (e.g., “ORGANIC” for food; “WATERPROOF” for coats)
  • Common surnames/very simple signs (single letters, basic shapes)

Tip: Coined/arbitrary words, distinctive logos, or distinctive combinations tend to pass more smoothly.

B. Relative grounds (conflicts) — Trademark Act Article 4

The examiner searches for prior identical or similar marks covering identical/similar goods/services.

If a conflict is found, it will be cited as a refusal ground.

Since 2024 reforms, Japan also allows consent (coexistence) in limited cases where there is no likelihood of confusion and the senior owner formally consents—but you still must satisfy the JPO that confusion won’t occur.

3) How long does JPO examination take?

  • Typical first action: ~5–8 months from filing (queue length varies).
  • Overall to registration: often 6–12 months.

Need speed? Consider:

  • Accelerated Examination/Early Examination (available if you already use the mark or have urgent reasons; additional documents required).

4) Outcomes of examination

No issues found → The examiner issues a decision allowing registration (you then pay the registration fee).

Issues found → The examiner sends a Notice of Reasons for Refusal (office action). This lists the legal grounds and evidence (e.g., citations).

    5) If you receive a Notice of Reasons for Refusal (office action)

    If you receive a Notice of Reasons for Refusal from the Japan Patent Office (JPO), you generally have about three months (often extendable) to respond through a Benrishi.

    The first option is to amend the goods/services, clarifying scope to avoid Article 3 (lack of distinctiveness under Japan’s Trademark Act) or to remove overlap that caused Article 4 citations.

    Next, submit substantive arguments showing inherent or acquired distinctiveness and the absence of likelihood of confusion (differences in appearance/sound/concept, trade channels, consumer attention).

    Where suitable under Japan’s new consent framework, file the senior owner’s consent together with evidence of no confusion.

    If only part of the application is problematic, file a divisional application so the clean portion can proceed.

    If a Decision of Refusal issues, appeal to the JPO Appeal Board (typically within three months). This pathway helps foreign applicants overcome a JPO Office Action and move toward trademark registration in Japan.

      6) After allowance: registration & what comes next

      If the application is allowed, pay the registration fee within the prescribed period (typically 30 days).

      Your mark registers for 10 years and can be renewed every 10 years indefinitely.

      Note: Japan operates a post-registration opposition system; third parties may file an opposition within 2 months after publication. Robust clearance and a well-drafted specification help minimize post-grant risk.

      7) Practical tips to improve your odds

      • Choose a distinctive sign (coined/arbitrary words, distinctive logos).
      • Draft a JPO-friendly specification using clear, accepted terms; avoid overly broad or vague wording.
      • Consider multi-class strategy carefully: it’s cost-efficient but a refusal in one class can delay others; division can de-risk.
      • Search before filing to identify conflicts early and plan arguments.
      • Line up evidence (use, market context) in case you need to show acquired distinctiveness or no confusion.
