Introduction to Common Law Trademark Infringement
Common law trademark infringement occurs when a business or individual uses a mark that is likely to confuse consumers with an existing mark, even if the existing mark is not registered with the USPTO. This type of infringement can be just as damaging as registered trademark infringement, and businesses must take steps to protect their brand.
To establish a common law trademark infringement claim, the plaintiff must show that they have prior use of the mark and that the defendant's use of the mark is likely to cause consumer confusion. This can be a complex and nuanced area of law, and businesses should consult with a trademark attorney to understand their rights and obligations.
Elements of a Common Law Trademark Infringement Claim
To establish a common law trademark infringement claim, the plaintiff must show that they have acquired trademark rights in the mark through prior use. This can be established by showing that the mark has been used in commerce and has acquired a secondary meaning, which means that consumers associate the mark with the plaintiff's goods or services.
The plaintiff must also show that the defendant's use of the mark is likely to cause consumer confusion. This can be established by showing that the defendant's mark is similar to the plaintiff's mark and that the goods or services offered by the defendant are similar to those offered by the plaintiff.
Prior Use and Trademark Rights
Prior use is a critical element of a common law trademark infringement claim. The plaintiff must show that they have used the mark in commerce before the defendant and that they have acquired trademark rights in the mark. This can be established by showing that the mark has been used in advertising, on packaging, and in other marketing materials.
The plaintiff must also show that the mark has acquired a secondary meaning, which means that consumers associate the mark with the plaintiff's goods or services. This can be established by showing that the mark has been used consistently and that consumers have come to recognize the mark as a source indicator for the plaintiff's goods or services.
Likelihood of Consumer Confusion
The likelihood of consumer confusion is a critical element of a common law trademark infringement claim. The plaintiff must show that the defendant's use of the mark is likely to cause consumer confusion, which means that consumers are likely to believe that the defendant's goods or services are associated with the plaintiff.
To establish a likelihood of consumer confusion, the plaintiff can show that the defendant's mark is similar to the plaintiff's mark, that the goods or services offered by the defendant are similar to those offered by the plaintiff, and that the defendant's use of the mark is likely to cause consumer confusion.
Defending Against a Common Law Trademark Infringement Claim
If a business is facing a common law trademark infringement claim, it is essential to take the claim seriously and to consult with a trademark attorney. The business can defend against the claim by showing that it has not used the mark in a way that is likely to cause consumer confusion.
The business can also defend against the claim by showing that the plaintiff does not have prior use of the mark or that the plaintiff's mark is not distinctive. The business can also argue that its use of the mark is fair use, which means that it is using the mark in a way that is not likely to cause consumer confusion.
