Stopping goods at the border
Owners of registered trademarks and copyrights can record those rights with U.S. Customs and Border Protection, which helps officers identify and detain suspected counterfeit or pirated goods at ports of entry. Patents cannot be recorded with customs in the same way; stopping patent-infringing imports usually goes through an exclusion order from the U.S. International Trade Commission, which runs its own fast-moving investigation and does not award money damages. Recordation is most useful when officers also get practical guidance, such as how to tell genuine product from fakes and which factories or shippers are authorized. When customs detains a shipment, the rights holder may be contacted for input, and the window to respond can be short.
Sellers you cannot easily find
Marketplace sellers often use rotating names and foreign contact details. Platform complaint programs remove listings and sometimes whole storefronts, but they rarely reach the money, and a seller can reopen under a new name. Some owners file a single lawsuit against many anonymous online sellers and ask the court early for orders freezing marketplace accounts, an approach that has become common and that some courts now examine more closely. Payment processors, domain registrars, and hosting providers each have their own complaint channels, and the information they release can link one storefront to the next. Keep test purchases, dated screenshots with URLs, and the packaging and labels from what arrives, since those connect a listing to a real shipper.
Choosing where to press
Trademark and patent enforcement abroad generally depends on rights held in that country, so a U.S. registration does little against a factory selling inside its home market. A practical program often combines several pressure points: customs at the border, platforms online, and litigation against operators who can be identified and who hold assets. In a first review we look at which rights are registered where, where the goods are made and sold, and which channel is likely to reduce the volume rather than just move it elsewhere. We also check whether your own registrations are recorded and current, because most enforcement tools assume that groundwork has already been done.
