What a claim usually needs
The central question in most trademark cases is whether the other party's use is likely to cause confusion about the source, sponsorship, or affiliation of goods or services. Courts weigh several factors together, including the similarity of the marks and the relationship between the products, and no single factor decides the case. A federal registration helps by creating legal presumptions about ownership and validity, but unregistered marks can also be protected under federal law and state law. Evidence of actual confusion, such as misdirected customer calls or reviews, can be persuasive, though it is not required. The strength of your mark matters as well, since distinctive or coined names usually receive broader protection than descriptive ones.
Timing and remedies
Waiting too long after learning of infringement can weaken a claim, especially for emergency relief, and may support a delay defense. In federal court, injunctions are the most common remedy, and federal law now presumes irreparable harm when a trademark owner shows likely success on the merits. Monetary relief can include the defendant's profits, the owner's damages, and costs, with enhanced awards and attorney's fees possible in exceptional cases. Counterfeiting claims carry their own remedies. What is realistic depends on the evidence and on how quickly you act.
Assessing your claim
Bring your registrations or applications, evidence of when and how you first used the mark, examples of the other party's use, records of any customer confusion, and your sales and advertising history. We assess the strength of your mark, the similarity of the uses, and possible defenses the other side may raise, including prior use in its own territory. In a first meeting we usually decide whether a demand letter, a Board proceeding, or a court filing is the appropriate first step. If the other party has applied to register its mark, an opposition may also belong in the plan, and opposition periods are short.
