Infringement is the act of violating the exclusive rights of a rights holder. Infringement of a copyright is generally when the copyright holder is deprived of one of the rights they are entitled to. For instance, if a piece of art work is displayed and the author's name is not displayed with the work, the authorship right of the copyright holder has been infringed and the holder is able to seek damages. Another example may be if someone writes an article based on another article that s/he has seen in a newspaper, but neglects to mention where the information came from. In this example, there may also be infringement.
