From Detection to Defense: A Powerful Duo that Tackles Trademark Proof Use

Once a trademark is registered, its owner must begin using it within a specific timeframe in many jurisdictions (often 3–5 years). Failure to do so opens the door for third parties to file for revocation on the grounds of non-use. This principle ensures that trademarks remain indicators of commercial origin and are not simply warehoused to block others from using them. 

A New Ally for Trademark Clearance: The “Vulnerable to Non-use” Column 

To help IP professionals make more informed decisions during trademark clearance projects, we’ve introduced a new feature in our Markify ProSearch™ reports: the “Vulnerable for non-use” column*:  

This new column flags trademarks that, based on local rules and applicable timeframes, have reached the point where they could be challenged for non-use. A clear “YES” indicator shows when a mark is potentially vulnerable, giving you a valuable signal during early-stage analysis. 

* It’s important to note that this column does not assess whether a mark is actually used in commerce. It simply reflects whether a trademark is subject to a use requirement.

Identifying a vulnerable trademark is just the first step. Proving non-use—or defending against such claims—requires solid, well-prepared evidence. And that’s where many rights holders struggle. 

Collecting, organizing, and presenting compliant documentation across different countries and formats is often complex and time-consuming. Mistakes or gaps can mean the difference between keeping or losing your rights. This is where our second solution for trademark proof of use classification comes into play. 

Monitoring and Strategic Vigilance 

Effective trademark management means not only registering and renewing your rights but also anticipating vulnerabilities. Regular monitoring of your portfolio can help identify marks at risk of cancellation due to lack of use. A comprehensive watch strategy also includes ensuring that trademarks cited in oppositions are still actively used—and that you have the documentation to prove it. 

Similarly, engaging in opposition or litigation using a trademark that hasn’t been used (or for which use cannot be demonstrated) can backfire, weakening your position or even resulting in loss of rights. 

Declarations of Use and Local Compliance 

In some countries (e.g. the United States, the Philippines, Argentina...), owners are required to submit Declarations of Actual Use (DAU) or similar affidavits to maintain their trademarks. Failure to comply leads to cancellation—another reason why evidence of use must be collected in a timely, strategic manner, and according to local standards. 

If you manage a portfolio of trademarks and are unsure whether your use documentation is compliant, complete, or up to date, now might be the right time to explore new solutions.
