What is a Common Law Trademark?

Understanding Common Law Trademarks: What You Need to Know

A common law trademark, also known as an unregistered trademark, is a mark (such as a name, logo, or slogan) used by a business or individual to identify their goods or services without formal registration with a trademark office, such as the United States Patent and Trademark Office (USPTO). These trademarks are established through actual use in commerce, meaning the mark gains legal recognition by being actively used to represent a brand in the marketplace.

Unlike registered trademarks, which are officially recorded with a government authority, common law trademarks rely on the principle of “first use” to establish rights. They still provide valuable legal protections for businesses and individuals.

Legal History of Common Law Trademarks

The concept of common law trademarks has deep roots in English common law, which forms the basis of much of the legal system in the United States and other common law jurisdictions. Historically, trademark protection emerged to prevent consumer confusion and protect businesses from unfair competition. In the absence of formal registration systems, courts recognized trademark rights based on a business’s established use of a mark in commerce.

In the U.S., common law trademark principles predate federal trademark law, such as the Lanham Act of 1946, which formalized trademark registration. Before federal legislation, businesses relied solely on common law to protect their marks, with courts resolving disputes based on evidence of use, consumer recognition, and market presence. Even today, common law trademarks remain a critical part of intellectual property law, particularly for small businesses or startups that may not yet have the resources to register their marks.

Legal Foundation of Common Law Trademarks

The legal foundation for common law trademarks lies in the principle of priority of use. Under common law, the first person or entity to use a mark in connection with specific goods or services gains trademark rights. These rights are grounded in:

  1. Use in Commerce: To claim a common law trademark, the mark must be actively used in commerce to identify goods or services. This could include displaying the mark on products, packaging, or marketing materials.
  2. Consumer Recognition: Courts often consider whether the mark has achieved “secondary meaning,” where consumers associate the mark with a specific source. This strengthens the mark’s legal standing.
  3. State and Common Law Protections: In the U.S., common law trademarks are recognized under state laws and common law principles, which vary by jurisdiction. Additionally, the Lanham Act provides some federal protections against unfair competition, even for unregistered marks, under Section 43(a).

Examples of Legal Defenses for Unregistered Trademarks

When defending a common law trademark in a legal dispute, the trademark owner must demonstrate their rights and the validity of their claim. Common defenses include:

  1. Priority of Use:
    • Example: If a local bakery has been using the name “SweetTreats” since 2018 and a new bakery in the same city starts using a similar name in 2023, the original bakery can assert priority of use to prevent confusion. Courts will look at evidence like dated receipts, advertisements, or customer testimonials to confirm the first use.
  2. Secondary Meaning:
    • Example: A small clothing brand uses an unregistered logo that becomes widely recognized. If another company tries to use a similar logo, the original brand can argue that its logo has acquired secondary meaning, meaning consumers associate it exclusively with their brand.
  3. Fair Use or Non-Commercial Use:
    • Example: If a business accuses another of infringing its common law trademark, the accused party might argue that their use of the mark is descriptive (e.g., using “Apple” to describe fruit rather than electronics) or non-commercial (e.g., parody or commentary).

Why Consider a Common Law Trademark?

Common law trademarks are a cost-effective way for businesses, especially small or local ones, to establish brand identity without the expense of federal registration. They offer protection against copycats.
