The first option we are going to discuss is Copyright. This is the most protective, and restrictive measure that can be taken to protect your creative works. Even if someone were to steal your creative works you still have ownership of it due to copyright law as defined by copyright.gov:
“§ 102 . Subject matter of copyright: In general28
(a) Copyright protection subsists, in accordance with this title, in original works of authorship fixed in any tangible medium of expression, now known or later developed, from which they can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device. Works of authorship include the following categories:
(1) literary works;
(2) musical works, including any accompanying words;
(3) dramatic works, including any accompanying music;
(4) pantomimes and choreographic works;
(5) pictorial, graphic, and sculptural works;
(6) motion pictures and other audiovisual works;
(7) sound recordings; and
(8) architectural works.
(b) In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work.”.
As a result you can punish whoever takes your work without your permission to the full extent of the law, and get reparations for the loss of profit and damages incurred. These proceedings however, require a large amount of money, a lawyer, and a court of law. If you are willing to front the cost this would be your best option for protecting your creative works.
