This could discourage people who simply have fair use or parody defense from seeking registration. Is that legal, to threaten lawsuit without at least being clear on this point?
@muCephi - in addition to the response @oswriter gave, I'll add the following: who is threatening anyone with a lawsuit?
I'm seeing a common misconception among various people that the guidelines are various things that they are not. They are not a threat to sue if a filmmaker does not comply with them. They are not a threat to sue if a filmmaker affirmatively does anything that is prohibited by the guidelines. Finally, they are not even "rules" to which there is any stated consequence if they are broken.
They are, merely, exactly what they say they are: guidelines which, if a filmmaker follows all of them, he or she can consider himself or herself free from the threat of a lawsuit by the studio. However, there is no corresponding statement – express or implied – in the guidelines that there is automatically any punitive consequence to not following the guidelines. The Studio may object or it may not. The only clear consequence from not following any of the guidelines is that the studio has not affirmatively told you that they will not object to your production. That's it.
The guidelines simply provide a safe harbor if you follow all of them – but they do not in any way constitue a threat of - or grounds for - liability if you do not. It is strictly the choice of the filmmaker as to whether it wants to follow the stated conditions and avail itself of the safe harbor that is being offered.
