Analysis of the “First to Use” Principle in U.S. Trademark Registration

In the U.S. intellectual property system, the establishment of trademark rights follows the "First to Use" principle, which differs from the "First to File" principle adopted by many other countries. This principle reflects U.S. law’s respect for actual market usage and aims to protect the legitimate rights of trademark users, preventing malicious trademark registrations and trademark hoarding. This article will analyze the uniqueness and practical impact of this principle from the perspectives of legal content, practical operations, and international comparisons.

I. Legal Content of the "First to Use" Principle

Logic of Priority Recognition
The U.S. Lanham Act clearly states that trademark rights are determined based on "first commercial use" rather than "registration time." This means that even if a trademark is not federally registered, if the prior user can prove that the trademark has been commercially used in a specific region or field, it can challenge subsequent applicants for registration. For example, if a local company has been using an unregistered trademark for a long time, when another company applies for the same trademark in the same field, the former can invoke "prior use" to request the rejection of the registration or limit its scope.
Distinction Between Actual Use and Intent-to-Use
The U.S. trademark registration process strictly distinguishes between "Actual Use" and "Intent-to-Use." Applicants must choose the appropriate basis for their application (Section 1(a) or 1(b)) based on their usage status:

Section 1(a): If the trademark is already in use at the time of the application, the applicant must provide the date of first use and evidence of commercial use (e.g., product labels, sales records).
Section 1(b): Allows applicants to submit an application based on "bona fide intent to use" the trademark, but the applicant must file a statement of use within 6 months (extendable up to 3 years) after the approval, otherwise, the application will be considered abandoned.

This mechanism balances the flexibility of commercial practices while preventing shell companies from abusing the registration process.

Coordination of Federal Registration and State-level Rights
The U.S. operates a dual-level trademark protection system, with both federal and state protections. Unregistered trademarks may only be protected under common law at the state level, while federal registration grants nationwide exclusive rights. In the event of a conflict, the "First to Use" principle requires courts to weigh the parties' actual use time, geographic scope, and commercial impact, using the "natural expansion principle" or "market penetration standard" to define the boundaries of rights.

II. Advantages and Challenges of the "First to Use" Principle

Advantages:

Encourages Actual Trademark Use: By granting priority rights to those who use the trademark in commerce, this principle curtails trademark squatting, ensuring a true connection between trademarks and commercial activity.
Protects the Interests of Small and Local Enterprises: Local businesses can still claim rights through common law even if they have not registered their trademarks, preventing large national companies from overpowering them.
Enhances Market Transparency: Consumers can identify stable sources through trademarks that have been in use for a long time, reducing the risk of confusion.

Challenges:

Heavy Burden of Proof: The prior user must provide extensive evidence, such as historical sales records and advertising materials, which can be costly and time-consuming.
Complexity in Cross-State Operations: The limited scope of common law protection may cause challenges for businesses expanding to other states, potentially facing opposition from federally registered trademarks.
Adaptation Challenges for International Applicants: Many countries adopt the "First to File" principle. Foreign businesses that have not used the trademark in the U.S. may lose protection due to priority disputes.

III. Key Strategies in Practical Operations

Timely Federal Registration
Although common law protection exists, federal registration remains the best way to strengthen rights. Businesses should apply for registration as soon as they begin commercial use or use the "Intent-to-Use" mechanism to secure an early filing date when expanding into new markets.
Systematic Evidence Preservation
Maintain records of first use dates, sales contracts, product packaging, advertising campaigns, and other critical evidence to form a complete chain of proof for potential disputes.
Regular Monitoring and Opposition Procedures
Regularly monitor the USPTO trademark database for similar trademark applications, and take action through opposition or cancellation procedures to protect one’s rights.
Consideration of International Trademark Strategies
For multinational companies, strategies should be designed based on the differences between the "First to Use" and "First to File" countries, leveraging international treaties such as the Madrid Agreement to avoid conflicts.

IV. Insights from International Comparisons

In stark contrast to the U.S., countries like China and the European Union operate under the "First to File" system. In China, trademark rights are granted to the first applicant, even if there is prior use, except for well-known trademarks. This difference requires businesses to adjust their strategies based on the legal characteristics of their target markets: in the U.S., the approach should be "use first, register to strengthen," while in China and similar markets, it should be "register first, protect through defense."

Conclusion

The "First to Use" principle reflects U.S. law's respect for genuine market competition, but its complexity raises higher compliance demands for businesses. In a globalized business environment, companies must develop trademark management strategies that balance efficiency and security to remain competitive in the intense brand marketplace.
