Javascript Copyright Legal Jargon
I developed all of the javascript code for a particular website, and I mean ALL from scratch.  There is weeks worth of code I have in a particular javascript file.  I know that anyone could take it at anytime (or parts within) without me knowing, however I am more concerned about how the text written in the copyright holds up legally?

    /**
     * Scripting in an XXX Site Environment
     *
     * Copyright (c) 2011 My Name (email@email.com)
     * Any use of the code written here-in belongs to the developer
     * and is hereby the owner.  If used, one must have strict
     * approval by the developer of the code written here-in.
     * The developer may at anytime change, modify, add, or delete
     * any content contained within.
