What is a "trademark" or "service mark"?
The trademark distinguishes and authenticates a product of a particular manufacturer from similar products offered by others. The owner of a Trademark has the right to prevent others from using the same or similar trademark on their products.
A "service mark" is a form of trademark that is used in the sale or advertising of services. The service mark distinguishes the services offered by one business from similar services offered by other businesses.
Both trademarks and service marks can be registered with the United States Patent and Trademark Office - and states can regulate trademarks and service marks used within the particular state.
A mark is not eligible to be registered if it is:
(a) immoral, deceptive or scandalous matter,
(b) flag of coat of arms or other insignia of the United States, or of any state, municipality, or foreign nation,
(c) a name, portrait, or signature identifying a particular living individual except with that individual's written consent, or the name, signature or portrait of a deceased President of the United States during the life of the President's spouse, except with the spouses written consent,
(d) a mark that resembles one already registered that is likely to cause confusion, mistake or deception,
(e) a mark that is merely descriptive, or a deceptive mis-description, of goods, or primarily a geographical description or deceptive geographical mis-description of goods, or a surname - unless the mark has become distinctive of the applicant's goods in commerce.
