Copyright y copyleft

Copyright: Es una ley que rige la propiedad intelectual. Engloba las obras de arte, las literarias, las musicales y las escénicas por un periodo de 50 años después de la muerte de su autor. Esta ley protege la obra desde el momento en que se crea sin necesidad de registrarla.
Intellectual property divides intellectual creations into three parts:

-Copyrights
-Trademarks
-Patent

-Copyrights protect expression:
Copyright protects creative expression that has been reduced to a tangible form, such as a book, piece of recorded music, computer program, screenplay, painting, photograph, or motion picture.


-Trademarks protect names:
Trademark protects brand names, literally marking items in trade. The idea behind trademark is to protect the consumer by giving them some confidence that items branded with a certain mark are authentic and come from where they purport to come from.


-Patent Protects ideas:
Patent protects innovation. While you can't copyright an idea, you can patent one.
