As the Intellectual Property surrounding the Copyright of original work can be highly valuable, not owning the rights attached to a copyright can reduce the value of a company or business.
To demonstrate the usefulness of a Deed of Copyright Assignment, let's take the example of artwork created for a company or businesses sales material. Unless the person who creates the artwork is your employee (in which case the governing Copyright Act 1968 gives you, the employer, ownership), you will need a Deed of Copyright Assignment to transfer ownership of the copyright from the creator to yourself. This means that if you engaged a graphic design company to create your artwork the designer automatically owns the copyright in your new artwork. To transfer the copyright to you, you will need a Deed of Copyright Assignment executed by the designer to ensure that you now own the Copyright surrounding that work. Once you get the copyright, you have the right to do, or to authorise another person to do, certain acts in relation to that work.
