A trademark serves to identify a good or service, and to distinguish that good or service from others. The trademark may be a word, several words (such as a slogan), a design, symbol, graphic or any combination of these elements.
Copyright refers to laws that regulate the use of the work of a creator, such as an artist or author.
Work-for-hire refers to the situations in which a creator of a work does not retain the rights to that work. By default, and artist or designer owns the copyright to his or her work. Work-for-hire includes two exceptions to that rule.
