In the context of copyright law, a work is defined as any original creation of the mind that is expressed in a perceivable form. This definition encompasses a wide range of productions in the fields of art, literature, music, film and architecture among others. To be protected by copyright, a work must be original, meaning it must reflect the personality of its author and be the result of their creative choices.
The notion of originality is central to the legal definition of a work. It does not require a high level of creativity or innovation, it is sufficient for the work to bear the personal imprint of its author. Works can include texts (such as novels, poems, plays), musical compositions, films, photographic works, paintings, sculptures and even certain software.
Legally, works are protected from the moment of their creation without the need for registration or specific formalities, depending on the legislation of most countries. This protection aims to allow creators to control the use of their works and to benefit from the fruits of their creation, while also promoting the cultural and intellectual development of society.
