     Intellectual property (IP) is a product of the mind that has commercial value . The concept

dates back to1623,when the first patent law to protect IP rights was passed. IP rights protect

an artist from having his/her creative ideas copied by another. For example. if somebody 

generates an idea for a novel, that idea is protected by IP rights. If someone else wishes to

represent the idea or develop it further, he/she  must consult the original artists,

    who will normally be rewarded   financially for its use. Back in the 17th century, IP rights

were primarily carried out to protect newly developed manufacturing processes against stealing ,

but today, intellectual property rights are also enjoyedby those who create music, art and literature.

     In recent years, IP rights have been the focus of a great deal of discussion because of a

technology which looks set to weaken them altogether: the Internet. Many years ago, if you

wanted a recording of a song, you would have to purchase it from a music store;if a novel,from a

bookstore. In those days,IP rights were easily protected since it was very difficult to obtain

intellectual property without paying for it. However, a lot of IP, including songs,films,books

and artwork,can be downloaded today free of charge using the Internet. This practice has now

taken the world by storm,dramatically affecting the way in which we view IP rights.
