If the preemptively registered trademark is in the preliminary announcement period, you can file an objection with the Trademark Office. 2. If the registered trademark has been approved for registration, you can apply to the Trademark Review and Adjudication Board for cancellation within five years after the trademark is registered; if the registered trademark is a well-known trademark, there is no time limit for filing a cancellation application. 3. If the preemptively registered trademark has not been used for a long time after registration, a cancellation application can be filed with the Trademark Office on the grounds of "stopping use for three consecutive years." 4. Re-register the trademark. The trademark cannot be similar to the original trademark. As for the popularity of the trademark, you don’t have to worry about it. As long as the product quality is good and you pay attention to publicity and promotion, you can still achieve good sales. A trademark does not necessarily have to correspond to a business name.
