What a Trademark is and What it Does.
A trademark is any word, name, symbol, or device, or combination thereof, used to identify and distinguish the goods (i.e., products) of one supplier from those of others. A service mark is the same as a trademark, but is used in connection with services rather than goods...
...Virtually all of the rules that apply to trademarks apply equally to service marks and further references to “trademark” or “mark” herein include both trademarks and service marks.
Contrary to what many believe there is no protection for a mark just because you were the first to think of it. Similarly, filing a state “doing business as” form, organizing a corporation using the mark as a company name, or registering the name with a city or county authority confers no trademark rights. Trademark protection arises only when a mark is used in connection with goods or services.
