Trademark renewal deadlines are among the most commonly misunderstood aspects of trademark ownership. Many businesses lose valuable registrations simply because they were unaware of when action was required. Understanding what happens between the 5th and 6th year mark and the 10-year renewal is essential for maintaining trademark rights.

The 5th to 6th Year Filing Explained

Between the fifth and sixth year after registration, trademark owners must file a Declaration of Use. This filing confirms that the trademark is actively used for all listed goods or services.

Sharon notes:

“You cannot just say you are using the trademark. You have to prove it, and the proof has to match exactly what is registered.”

Evidence must reflect real-world commercial use, not mockups or outdated materials.

Declaration of Incontestability and When It Makes Sense

At the same time, businesses may file a Declaration of Incontestability. This filing strengthens the trademark by limiting certain legal challenges.

However, it is optional and not appropriate for every situation. The trademark must meet eligibility requirements, including continuous use for five years.

What Happens at the 10-Year Renewal

Between the 9th and 10th year after registration and every ten years after that,   trademark owners must renew their registration by confirming continued use. This filing is mandatory.

Failure to file results in cancellation, and there is no reinstatement after the grace period ends.

Consequences of Missing Renewal Deadlines

Missing a renewal deadline can lead to:

• Permanent cancellation of the trademark
  
• Loss of enforcement rights
  
• Increased risk of brand infringement
  
• Costly re-filing with uncertain approval
  

As Sharon explains:

“Many business owners assume they will get reminders. The USPTO reminders are a courtesy, not a guarantee.”

Frequently Asked Question

1. What filing is required between the 5th and 6th years after trademark registration?

Between the 5th and 6th year after registration, trademark owners must file a Declaration of Use (Section 8) with the USPTO. This filing confirms that the trademark is still actively used in commerce for all listed goods or services and must be supported by accurate proof of use. More guidance on these filings is available through the firm’s trademark services.

2. Is a Declaration of Incontestability required at the 5–6 year mark?

No. A Declaration of Incontestability (Section 15) is optional. When filed and accepted, it can strengthen a trademark by limiting certain legal challenges, but only if eligibility requirements are met, including continuous use of the mark for five years. Not every trademark qualifies, and filing should be evaluated carefully.

3. What happens if a business misses the 10-year trademark renewal deadline?

If a trademark owner fails to file the required renewal between the 9th and 10th year (including any applicable grace period), the USPTO will cancel the registration. Once canceled, the registration cannot be reinstated, and any future protection would require filing a new application with no guarantee of approval.

4. Does the USPTO always send reminders about trademark renewal deadlines?

The USPTO may send courtesy reminders, but they are not guaranteed. Trademark owners are responsible for tracking their own deadlines. Relying solely on reminders can result in missed filings and permanent loss of rights. Many businesses choose to work with counsel or monitor deadlines through professional systems, such as those used at Adams Law Office.

5. When should a business contact a trademark attorney about renewal deadlines?

A trademark attorney should be consulted when approaching renewal deadlines, when there is uncertainty about whether evidence qualifies as valid use, or when managing multiple trademarks. Early guidance can reduce costly mistakes. Businesses with questions about renewal timing or filings can contact us to discuss their specific situation.
