Art Law. Intellectual property laws give owners the exclusive right to profit from a work for a particular limited period. For copyrighted material, the exclusive right lasts for 70 years beyond the death of the author. The length of the right can vary for patents, but in most cases it lasts for 20 years. Trademark rights are exclusive for ten years and can be continually renewed for subsequent ten-year periods. Intellectual property laws do not fall in the category of Criminal Law, per se.
