In contrast, Adobe Systems lists many Photoshop developers in its credits. In both cases, the software is the property of the employer company. In both cases, the actual creators have moral rights. Similarly, newspapers regularly write press articles written by their employees, and publishers award authors and illustrators who produce comics with characters like Batman or Spider-Man, but publishers own the copyright to the work. However, articles published in scientific journals or works produced by freelancers for journals are generally not works created as a rental work, which is why it is common for the publisher to require the copyright owner, the author, to sign a copyright transfer, a short legal document that transfers certain copyright from the author to the publisher. In this case, the authors retain the copyright in their work that has not been granted to the publisher. [Citation required] When it comes to copyright, the owner of a protected work is usually the creator. No big surprise. However, there are circumstances in which the author of the protected work is not the owner and is therefore not entitled to copyright protection.
You can determine if a particular work has co-ownership by reviewing the Copyright Office`s documents. For example, a recording for a song may indicate that a composer and lyricist are co-owners of a song. An author can grant the client his copyright (if applicable). However, if it is not a rental work, the author or the author`s heirs may exercise their right to terminate the donation. The termination of a grant may not take effect until 35 years after the implementation of the grant or, if the grant covers the right of publication, no earlier than 40 years after the implementation of the grant or 35 years after publication under the grant (whichever comes first).  In any case, any assignment or license of copyright is always expressly subject to full payment of the compensation due to you under the Agreement. It is very important to make sure that your copyright is not legally transferred until you have been paid. If a copyright assignment or license is not related to payment, the courts have ruled that the copyright was actually transferred at the time the contract was signed.
This does not allow you to claim that continuing to use your artwork without payment constitutes copyright infringement. .
