Even with a registered trademark, common law rights can pose significant challenges.
1. Understanding Common Law Trademarks
Establishment Through Use: Common law rights are acquired by simply using a mark in commerce.
Geographic Scope: These rights are generally limited to the geographic area where the mark is used.
Impact: A common law trademark owner with prior use can have superior rights in their area of operation.
2. Grounds for Challenging a Registered Mark
Common law trademark owners can challenge a registered mark through:
a. Opposition Proceedings
Timeline: Must be filed within 30 days after the mark is published in the USPTO’s Official Gazette.
Grounds: Prior use of a confusingly similar mark, likelihood of confusion, or dilution.
b. Cancellation Proceedings
When: Can be filed any time after registration, with some grounds limited to the first five years.
Grounds: Prior common law rights, abandonment, fraud, or the mark becoming generic.
Impact: A successful opposition or cancellation can prevent or remove registration.
3. Likelihood of Confusion Claims
A common law trademark owner may argue that:
Consumer Confusion: The registered mark is likely to cause confusion with their mark.
Priority of Use: They have been using the mark in commerce before the registrant.
Impact: Courts may side with the prior user, affecting the registrant's rights.
4. Infringement Actions
Common law owners can file lawsuits alleging trademark infringement based on:
Use in Commerce: Unauthorized use of a mark causing confusion.
Damages: Seeking monetary damages or injunctive relief.
Impact: Legal action can result in costly litigation and potential loss of trademark rights.
5. Defenses Against Common Law Claims
Registered trademark owners can defend themselves by:
Challenging the Validity: Arguing that the common law mark is not protectable.
Geographic Limitations: Asserting that the common law rights are limited geographically.
Laches and Acquiescence: Claiming that the common law owner unreasonably delayed enforcement.
Impact: Effective defense strategies can mitigate risks.
6. Importance of Prior Searches
Comprehensive Searches: Including common law databases, business directories, and internet searches.
Due Diligence: Helps identify unregistered marks that could pose conflicts.
Impact: Early identification of potential issues allows for strategic planning.
Conclusion
Trademark registration is a nuanced process influenced by various factors such as distinctiveness, likelihood of confusion, and proper use in commerce. While registration provides substantial legal benefits, it does not make your mark impervious to challenges. Common law trademark rights can significantly impact registered trademarks, especially when prior use can be established.
To navigate these complexities:
Choose a Distinctive Mark: Enhances registrability and protection.
Conduct Thorough Searches: Identify potential conflicts before applying.
Monitor and Enforce Your Mark: Protect against infringement and dilution.
Seek Legal Counsel: An experienced trademark attorney can provide invaluable guidance.
By understanding the factors that affect trademark registration and the potential impact of common law trademarks, businesses can better protect their brands and intellectual property assets.
