A trademark is a word, phrase, symbol, or design that identifies the source of goods or services. A trademark can be an original design or an invented word, but it can also be an descriptive term recognized by the public as indicating a particular source. Unlike patents and copyrights, trademarks are renewable indefinitely, but companies often change their trademarks over time.
