The Complete Guide to Understanding Trademark Infringement and Protecting Your Brand
Discover the key legal concepts, practical steps, and important case examples to safeguard your business from unauthorized use of your trademark.
In today’s competitive marketplace, a trademark is more than just a logo or a name—it is the very essence of your brand’s identity. It distinguishes your products or services from others and builds consumer trust and recognition. When another party uses your trademark without authorization, it can lead to confusion and harm the value you have worked so hard to build. This unauthorized use is known as trademark infringement.
For any business owner, a solid understanding of trademark infringement is essential for protecting your intellectual property and brand reputation. This guide will walk you through the key legal principles, the elements required to prove a claim, the steps to take when infringement occurs, and what to expect in the legal process.
At its core, trademark infringement is a violation of the exclusive rights attached to a registered or unregistered mark. Infringement typically occurs when a party uses a mark that is identical or confusingly similar to another’s trademark, particularly in connection with identical or similar goods and services. The central question in most infringement cases is whether the use of the mark is “likely to cause confusion” among consumers about the source, origin, or affiliation of the goods or services.
While the specific factors may vary slightly by jurisdiction, courts generally consider the following elements:
To succeed in a trademark infringement lawsuit, a plaintiff must generally establish three key elements:
The primary federal law governing trademark infringement in the United States is the Lanham Act, which provides the legal framework for both registered and unregistered marks.
💡 Tip: Registered vs. Unregistered Trademarks
While common law rights can protect an unregistered mark, a federal registration provides significant advantages. It grants nationwide protection and a legal presumption of ownership, making it easier to enforce your rights.
If you believe your trademark has been infringed, the first step is to gather evidence and consult with a legal expert. This involves documenting the infringing party’s use of the mark with screenshots, product packaging, and other materials.
Common steps in the legal process include:
If a trademark infringement claim is successful, the trademark owner may be awarded various remedies, including:
Examining real-world cases helps illustrate how courts apply the likelihood of confusion standard. For example, in Starbucks v. Obsidian Group, Starbucks sued a smaller coffee shop for using the name “Freddoccino” for a beverage, claiming it was confusingly similar to their “Frappuccino” trademark. The lawsuit alleged that the names had a similar number of syllables and endings, which could mislead consumers. The case was settled out of court in Starbucks’ favor, with the smaller shop agreeing to change the name.
Case Example: Adidas v. Forever 21
In 2017, Adidas filed a lawsuit against Forever 21 for using its registered “three stripe” trademark on track pants and shorts. Adidas alleged both trademark infringement and dilution, arguing that the design was a famous source indicator worthy of protection. The case was settled out of court, demonstrating the significant legal power of a famous and well-promoted mark.
Trademark infringement is a serious issue that can impact your business’s bottom line and reputation. By understanding the key legal concepts and taking proactive steps, you can effectively protect your brand.
Trademark infringement is the unauthorized use of a mark that is likely to cause consumer confusion. The central legal test is the “likelihood of confusion,” which is evaluated based on factors like the similarity of marks and relatedness of goods. The legal process often begins with a cease and desist letter and can escalate to a lawsuit, where remedies may include injunctions and monetary damages. Federal registration is highly recommended for strong protection.
The primary federal law is the Lanham Act, which provides the legal framework for both registered and unregistered trademarks.
No, you can sue for infringement based on common law rights from using your mark in commerce, but a federal registration provides significant advantages, including nationwide protection.
Remedies can include an injunction to stop the infringing use, monetary damages for harm caused, and an accounting for the profits the infringer earned from the unauthorized use.
The most crucial and often contentious element is proving a “likelihood of confusion”—that consumers are likely to be confused about the source or origin of the goods or services due to the infringing mark.
