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

to 1623 when the first patent law to protect IP sights was passed. IP rights protect the artist from having

his/her creative ideas copied by another. For example, if somebody generated 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 enjoyed by those who creative 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, form a book store. 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.
