Goodwill travels with the mark
Under U.S. law, a trademark is transferred together with the goodwill of the business it represents. An assignment that tries to sell the bare mark without that goodwill, called an assignment in gross, risks being treated as invalid, and the buyer may not inherit the seller's priority. In practice, agreements recite the transfer of goodwill and, where relevant, the assets or know-how needed to keep offering consistent goods or services. An application based on intent to use generally cannot be assigned before use has been shown, except to a successor to the business it relates to.
Recording and cleaning up the record
Assignments of federal registrations and applications can be recorded with the USPTO, which updates the public record and protects against later conflicting transfers. Foreign registrations need their own recordals in each country. Many assignment problems are really record problems: a registration still in a founder's personal name, in a dissolved entity's name, or in a predecessor company's name. Domain names, social media handles, and state registrations do not move with a USPTO recordal and need separate steps.
Terms worth negotiating
Beyond the transfer itself, the agreement usually addresses the seller's warranties about ownership and disputes, any license back to the seller during a transition, and how existing licenses to third parties are handled. If the seller will keep running a related business, coexistence terms can prevent a later conflict. We review the registrations and their status, check for pending oppositions or cancellations, and draft the transfer so the buyer can enforce the mark from the day after closing. Bring the registration list, any existing licenses, and the deal documents.
