What is protected by copyright?

Copyright protects works (texts, music, drawings, photographs, films, etc.) that have been created and that are original. 

The work must exist in a tangible form
A work must be capable of being observed by a third party and must be able to be communicated. It must therefore have taken a certain form.

In this sense, ‘abstract creations’ such as ideas, concepts, styles and methods are not protected. The chosen form (written, drawn, filmed, spoken, etc.) does not matter.

It doesn’t have to be completely finished to be protected. A draft version, a sketch or a plan will suffice.

The work must be original
The work must carry the personality of its creator. The term ‘originality’ is interpreted broadly. A professional or artistic character is not required.

Real facts such as historical or scientific events are not protected.

In case of doubt, it is up to a judge to decide whether or not a work is protected.
