In today’s competitive market, your brand is one of your most valuable assets. People typically recognize your brand through its name and trademark. It is what makes your clients recognize your products and services, distinguishing them from others. Unfortunately, trademark infringement is a significant concern for businesses, particularly online businesses, where counterfeit goods or fake websites can damage their reputation and mislead customers. Whether you run an E-commerce store or a tech startup, understanding what counts as trademark infringement and how to protect your brand is essential for safeguarding your business. Read on to learn more.
Trademark infringement happens when someone uses your trademark or service name without permission in a way that is likely to confuse consumers about the source of goods or services. Trademark infringement can include:
According to the United States Patent and Trademark Office (USPTO), to prove a trademark infringement in court, you must demonstrate that:
The unauthorized use is likely to cause consumer confusion.
When determining whether trademark infringement has occurred, the court may consider factors such as similarity of the trademarks, overlapping customer bases, marketing channels, and any documented consumer confusion.
Trademark infringement can have serious consequences for your business. Customers may mistake counterfeit or inferior products for yours, leading to a lack of trust and eroding the loyalty you’ve built for many years. Additionally, you may experience financial loss when sales drop, your brand may be diluted, leading to less distinctiveness, and consumers may struggle to identify your actual products, which can weaken your competitive advantage.
Having seen how consequential trademark infringement can be for you and your business, understanding how to protect it is imperative. To do this, consider the following:
Registering your trademark with the USPTO gives you protection and public notice of your rights. It is best to consult a trademark attorney to guide you through the process and ensure all your products are covered.
Before registering or enforcing your trademark, check the USPTO database, domains, social media, and state trademark agencies to ensure your trademark is unique. This can help spot potential conflicts early and avoid costly disputes.
Ensure you update registrations for new products, services, or significant brand changes, and file maintenance documents at the required intervals.
Registering a trademark doesn’t mean all your issues are sorted. Ensure to keep an eye on any unauthorized use, counterfeit goods, or misleading marketing. If you detect any trademark infringement, promptly contact an attorney. The attorney can help in crafting and sending cease-and-desist letters to prevent further damage, among other legal options.
Federal courts evaluate trademark infringement claims using the “likelihood of confusion” test, first articulated in Polaroid Corp. v. Polarad Electronics Corp., 287 F.2d 492 (2d Cir. 1961). The Polaroid factors—now applied by circuits across the country—include the strength of the senior mark, the degree of similarity between the marks, the proximity of the products, actual consumer confusion, the sophistication of buyers, and the quality of the defendant’s goods. No single factor is dispositive; courts weigh them together. The Ninth Circuit applies a similar eight-factor test from AMF Inc. v. Sleekcraft Boats, 599 F.2d 341 (9th Cir. 1979). Courts ask whether an ordinary consumer exercising ordinary care would be confused about the source, affiliation, or sponsorship of the goods.
Courts recognize three types of confusion: point-of-sale confusion at the moment of purchase, post-sale confusion among observers who see the goods afterward, and initial-interest confusion that lures a consumer to a competitor even if dispelled before purchase. The Ninth Circuit addressed initial-interest confusion in Brookfield Communications, Inc. v. West Coast Entertainment Corp., 174 F.3d 1036 (9th Cir. 1999), involving a competitor’s trademark used as a website metatag. E-commerce sellers who embed competitor brand names into product listings or ad keywords face liability on exactly this theory.
Trademark rights in the United States are governed primarily by the Lanham Act, 15 U.S.C. §§ 1051–1141n. Section 32, 15 U.S.C. § 1114, creates a civil cause of action for infringement of a registered mark. Section 43(a), 15 U.S.C. § 1125(a), extends protection to unregistered marks used in commerce and covers false designations of origin and trade dress infringement. Section 43(c), 15 U.S.C. § 1125(c), covers dilution by blurring or tarnishment for “famous” marks with widespread public recognition.
Registration on the USPTO’s Principal Register gives the owner a presumption of validity, constructive notice nationwide, and the right to use the ® symbol. Incontestability status, available after five years of continuous post-registration use under 15 U.S.C. § 1065, provides a near-conclusive presumption of validity. Without federal registration, rights arise only from actual use in commerce and are geographically limited—a serious disadvantage in online markets where customers span every state.
Section 35 of the Lanham Act, 15 U.S.C. § 1117, authorizes several categories of monetary relief. A prevailing plaintiff may recover the infringer’s profits, actual damages, and costs. Courts may treble damages for willful infringement. Attorney’s fees are available in “exceptional cases”—a standard the Supreme Court interpreted in Octane Fitness, LLC v. ICON Health & Fitness, Inc., 572 U.S. 545 (2014), to mean cases that stand out based on the strength of litigating positions or litigation conduct. In counterfeit goods cases under 15 U.S.C. § 1117(c), statutory damages range from $1,000 to $200,000 per counterfeit mark per type of goods, and up to $2,000,000 per mark for willful counterfeiting.
Injunctive relief is the most commonly sought remedy and is routinely granted when a plaintiff shows likelihood of success on the merits and irreparable harm. Courts may also order seizure and destruction of infringing goods, transfer or cancellation of infringing domain names, and recall of already-distributed products in serious cases.
Before filing suit, most trademark owners send a cease and desist letter. A well-crafted letter identifies the senior mark and its priority date, describes the infringing conduct with specificity, sets a concrete response deadline—typically 10 to 21 days—and lists the remedies the owner will pursue. These letters create a written record of actual notice, which supports a later willfulness finding and strengthens damages claims. They also sometimes resolve disputes without litigation entirely.
For online infringement, trademark owners can file takedown requests under platform IP policies, submit Uniform Domain-Name Dispute-Resolution Policy (UDRP) complaints with ICANN-accredited arbitrators to recover infringing domain names, and file complaints with U.S. Customs and Border Protection (CBP) to intercept counterfeit goods at the border. Amazon’s Brand Registry and similar programs on other platforms offer expedited removal of infringing listings for registered trademark owners, often resolving issues faster than federal litigation.
Defendants frequently assert fair use defenses. Descriptive fair use under 15 U.S.C. § 1115(b)(4) permits using a word in its primary descriptive sense rather than as a brand identifier. Nominative fair use, recognized in New Kids on the Block v. News America Publishing, Inc., 971 F.2d 302 (9th Cir. 1992), permits referencing another’s mark to identify that mark’s own goods when no reasonable alternative exists and the use does not suggest sponsorship or endorsement. Parody is a qualified defense that protects genuine commentary on the markholder but does not excuse free-riding that merely uses the mark to attract business.
Defendants may also challenge the mark’s validity through a cancellation proceeding at the USPTO’s Trademark Trial and Appeal Board (TTAB). Grounds include abandonment—non-use for three consecutive years creates a rebuttable presumption under 15 U.S.C. § 1127—fraud on the USPTO, and failure of the term to function as a mark. Laches and acquiescence can bar damages or injunctive relief when the trademark owner unreasonably delayed enforcement to the defendant’s detriment.
Digital commerce creates unique infringement vectors. Keyword advertising—bidding on a competitor’s trademarked name in Google Ads—has produced contested case law. Courts in the Second, Fourth, and Ninth Circuits generally hold that merely purchasing a keyword does not constitute trademark “use in commerce” unless the resulting ad copy is likely to cause confusion. 1-800 Contacts, Inc. v. WhenU.com, 414 F.3d 400 (2d Cir. 2005), limited liability for pop-up ads, while Network Automation, Inc. v. Advanced Systems Concepts, Inc., 638 F.3d 1137 (9th Cir. 2011), applied the Sleekcraft factors to keyword advertising with particular emphasis on consumer sophistication.
Social media and marketplace platforms present additional exposure. Unauthorized use of a brand’s trademark in product titles, hashtags, or branded content creates both platform-level takedown risk and potential federal liability. Sellers who list counterfeit goods on Amazon, eBay, or Etsy face statutory damages that can be catastrophic—$2,000,000 per mark per product type for willful counterfeiting. Brand owners should actively monitor these channels and maintain active USPTO registrations, which unlock platform enforcement tools not available to unregistered mark holders.
