How do we best protect our website IP?

A website has a number of components that can be copyright protected including the artwork (visual arts), the text, any photographs and videos and any software code. All of this is automatically copyright protected for the "creator" under U.S. law as soon as it is created and can be registered in the U.S. Copyright Office to be further protected which enables enforcement of copyright rights in federal court and statutorily defined damages amounts. I believe all of this can be registered in one electronically submitted copyright application available at http://www.copyright.gov.
The term "creator" is a legal issue because if the creation is by an employee during his/her employment, then by law the rights revert to the employer but there are many exceptions to this, especially in the independent contractor scenario.
There may be other forms of intellectual property available to protect the website. Any business serious about protecting all of its IP on and off its website should consult with an intellectual property attorney and the cost would be a worthwhile investment because failure to do so could cost a great deal more down the road.
