Ownership of copyright initially belongs to the author or authors of the work.  The “author” is generally the individual who created the work.  If an employee creates a work as part of his employment, the employer is considered to be the “author” for copyright purposes and therefore in such cases, the ownership in the work will vest with the employer.  Ownership in copyright is vested with the author of the work as soon as the work t is “fixed in a tangible medium of expression.”   Copyrights last for the life of the author plus 50 years if the author is a natural person, or for 150 years if the author is a corporation.
