Removing Blockages: A Guide to Article 50 Non-Use Cancellation Trials

One of the most effective tactical tools in Japanese trade mark practice is the non-use cancellation trial under Article 50 of the Trademark Act. When a registered mark is blocking your application, and you believe the owner has not been using it, Article 50 allows you to file a cancellation action — and the most powerful feature of this procedure is the reverse burden of proof. The trade mark owner, not the petitioner, must prove that the mark has been used.

The Legal Basis

Article 50 provides that any person may file a trial for cancellation of a registered trade mark if the owner or any licensee has not used the trade mark in Japan in connection with any of the designated goods or services for a continuous period of three years or more.

The three-year period is calculated backwards from the date the cancellation trial is filed. This means the owner must demonstrate use within the three years immediately preceding the filing of the cancellation action.

The Reverse Burden of Proof

This is the defining feature of Japan’s non-use cancellation system. Unlike many jurisdictions where the petitioner must prove non-use, in Japan:

• The petitioner files the cancellation trial and does not need to prove that the mark has not been used.
• The trade mark owner bears the burden of proving that the mark has been used in Japan for the designated goods or services within the relevant three-year period.

If the owner fails to respond or cannot provide sufficient evidence of use, the registration is cancelled. The petitioner does not need to present any evidence of non-use — the mere filing of the trial shifts the evidentiary burden entirely to the registered owner.

What Constitutes “Use”?

To successfully defend against a cancellation trial, the owner must prove use that meets the following criteria:

• Use in Japan: The use must have occurred within Japanese territory. Overseas use alone does not satisfy the requirement.
• Use on designated goods or services: The use must relate to at least some of the goods or services covered by the registration. Use on unrelated goods does not count.
• Use as a trade mark: The mark must be used in a manner that functions as a source identifier, not merely as decoration or description.
• Use of the registered mark or a “socially accepted identical” variation: Minor variations may be accepted if the mark is deemed identical based on conventional understanding. However, significant modifications may not qualify.

Evidence of use typically includes invoices, advertisements, product photographs, catalogues, web pages, and any other materials showing the mark in commercial use in Japan during the three-year period.

Use by Licensees

Use by a licensee qualifies as use by the owner for the purposes of Article 50. The owner does not need to prove personal use — use by any authorised licensee (exclusive or non-exclusive) is sufficient, provided the licence relationship can be established.

Partial Cancellation

Non-use cancellation is applied on a goods-by-goods or service-by-service basis. The petitioner can target specific goods or services within the registration, and the owner must prove use for each designated item that is challenged. If the owner can prove use for some goods but not others, the registration survives for the goods where use is demonstrated and is cancelled for the rest.

The Tactical Use of Article 50

Non-use cancellation is commonly used as a clearance tool when a prior registration blocks a new application. The typical workflow is:

1. The applicant files a trade mark application and receives a similarity refusal citing a prior mark.
2. The applicant investigates whether the cited mark appears to be in use in Japan.
3. If no evidence of use is found, the applicant files a non-use cancellation trial against the cited mark.
4. If the cancellation succeeds, the obstacle is removed and the applicant can proceed to registration.

This procedure is widely used and is considered a standard part of the Japanese trade mark practitioner’s toolkit.

Timing and Procedure

• A non-use cancellation trial can be filed by any person — there is no requirement to demonstrate standing or a particular interest.
• The trial is conducted by the Board of Trials within the JPO.
• The owner is notified and given an opportunity to submit evidence of use.
• If the owner fails to submit evidence, the registration is cancelled.
• The decision can be appealed to the Intellectual Property High Court.

Important Limitations

• Timing of evidence submission: The Supreme Court has ruled that use evidence may be accepted even at the court appeal stage, even if the owner did not respond at the JPO trial stage. This means a cancelled mark can potentially be revived on appeal if the owner produces belated evidence.
• Token use: Some owners maintain minimal or token use specifically to defend against cancellation trials. Even limited commercial activity may suffice if it constitutes genuine use as a trade mark.
• Katakana equivalents: Use of the Katakana version of a registered Roman-letter mark may not automatically constitute use of the registered mark. The forms must be considered identical based on conventional understanding.

Strategic Recommendations

• Investigate before filing: Before initiating a cancellation trial, investigate whether the cited mark appears in the Japanese market. Check online retailers, product listings, and industry directories.
• File promptly: If a cited mark appears unused, file the cancellation trial early to begin clearing the path for your own application.
• Target specific goods: If the cited mark is used for some goods but not others, target the cancellation at the specific goods that conflict with your application.
• Maintain your own use records: If you are a trade mark owner in Japan, keep organised evidence of use to defend against potential cancellation actions.

Key Takeaway

Article 50 non-use cancellation is one of the most practical and frequently used tools in Japanese trade mark practice. The reverse burden of proof makes it a powerful instrument: the petitioner simply files, and the registered owner must prove use or lose the mark. For applicants facing a similarity refusal based on a seemingly dormant mark, Article 50 is often the most efficient and cost-effective path to clearing the register and securing registration.
