What Causes Japan Trademark Disputes
Trademark disputes in Japan typically fall into one of four categories:
- Infringement — A third party uses a mark identical or similar to your registered trademark without authorisation
- Conflicting registrations — Two similar marks end up registered in overlapping classes due to examination error or changed circumstances
- Bad-faith squatting — A party registers your brand name in Japan before you, with no legitimate connection to the brand
- Dispute over ownership — Former partners, distributors, or licensees register or claim rights to marks they used under your authorisation

Trademark Dispute Resolution Process
- Assess your position — Confirm whether you have a registered trademark in Japan. Your enforcement options depend on this. Consult your Japanese attorney immediately
- Gather evidence — Collect proof of your rights and the infringing or conflicting use: registration certificates, sales records, correspondence, screenshots, product photos
- Send a cease and desist letter — In most cases, a formal letter from your attorney is the first and most cost-effective step. Many disputes are resolved at this stage
- File opposition (if within 2-month window) — If a conflicting mark has been published but not yet registered, file an opposition immediately
- File invalidation or cancellation trial — If a conflicting mark is already registered, file an invalidation trial (for bad faith or legal grounds) or a non-use cancellation trial (if the mark has not been used for 3+ years)
- Pursue civil litigation — If other routes fail, apply to court for an injunction and/or damages
- Consider negotiated settlement — In many disputes, a negotiated outcome — coexistence agreement, assignment, or licence — is faster and cheaper than full litigation

Common Mistakes
- No Japanese registration — Without a JPO-registered trademark, your enforcement options in Japan are severely limited. Unregistered marks have minimal legal standing
- Delayed action — Allowing a dispute to drag on without response can weaken your legal position. Act as soon as a conflict is identified
- Missing the 2-month opposition window — If a conflicting mark is published, opposition must be filed within 2 months. This deadline cannot be extended
- Attempting direct negotiation without an attorney — In disputes involving IP rights, negotiating without qualified legal representation often leads to unfavourable outcomes
- Not preserving evidence — Courts and JPO proceedings are evidence-driven. Keep dated records of your trademark use in Japan from day one
FAQ
What is the fastest way to resolve a trademark dispute in Japan?
A cease and desist letter from a Japanese trademark attorney is typically the fastest first step. Many disputes — particularly straightforward infringement cases — are resolved within weeks at this stage. More complex disputes involving conflicting registrations may require JPO proceedings or litigation.
Can I resolve a Japan trademark dispute without going to court?
Yes. Many disputes are resolved through: cease and desist correspondence, JPO opposition or invalidation proceedings, or direct negotiated settlement. Litigation is typically a last resort when other routes have been exhausted.
What if the conflicting trademark was filed in bad faith?
Japan's Trademark Act includes grounds for invalidating marks filed in bad faith. If a squatter registered your brand name with no legitimate purpose, an invalidation trial may succeed — but requires strong evidence and experienced legal representation. Contact your attorney immediately.
Does BrandAgent handle trademark dispute cases?
Yes. BrandAgent handles opposition filings, invalidation trials, non-use cancellation actions, and can advise on enforcement strategy. Contact us for an initial assessment of your dispute situation.
