Copyright

Copyright

• It is a legal concept, enacted by most governments, giving the creator of an original work exclusive right to it, usually for a limited time.

• It is distinct from other forms of creator protection such as Patents, which give inventors exclusive rights over use of their inventions, and Trademarks, which are legally protected words or symbols or certain other distinguishing features that represent products or services.

• It refers to laws that regulate the use of the work of a creator, such as an artist or author.
