Merely thinking of a great trademark is not enough, you have to use it. This does not mean that you have to be selling your goods, but you have to be using it publicly. Public use of your trademark will establish your priority and increase your protection. A few examples of public use other than actually selling your goods include presale announcements and soliciting/accepting orders. If you are not yet using your trademark, but plan on using it in the future and want to establish your priority as soon as possible, you can file an intent to use application. While your trademark will still not be fully registered until a statement of use is filed and accepted, the benefit is that once accepted your priority date will be the date you filed the application. In addition to using your trademark in a public manner, you must use your trademark in continuous commercial use. Just like you are dependent on your trademark for protection, your trademark is dependent on your use.
