What is a trademark? A trademark is a word, name, logo or device that is used in trade to designate the source of goods and to differentiate them from the goods of others. A servicemark is similar to a trademark but is used to identify the source of a service instead of a product. For example, the name of a restaurant would have a servicemark, and the name of the burger they sell would be trademarked. Trademarks can be used to prevent others from using a similar mark that may be confusing to consumers as to the source of the service or product.
What is a copyright? A copyright is used by authors, artists, musicians, etcetera to protect original creative works, either published or unpublished. A copyright gives the owner the exclusive right to reproduce the work or derivative works, distribute copies of the work or to perform or display the work publicly. The copyright protects the expression of the work rather than the subject matter.
