Trademark registration is not something that can be completed within a short time. It requires patience because it takes a significant amount of time to finish. Of course, no one likes to wait for a long time to get a trademark registered, particularly Amazon sellers who need to acquire a registered trademark quickly—this is where trademark assignment of an existing trademark comes into play.
Since the process of obtaining a trademark registration certificate is a long one, you may be considering the purchase of someone else’s registered trademark. Ultimately, trademarks are regarded as assets, so it should be easy to buy and sell them.
Unfortunately, buying someone else’s trademark is not as easy as it sounds—not by a long shot. Trademarks only become valid when they are used in commerce; that is to say, only when a trademark is attached to a product or product packaging, and when the product(s) having this trademark are sold in marketplaces, does that trademark become legally valid. Additionally, if you provide services, the trademark must be shown when providing the services or when advertising them.
