So essentially, this is a lawsuit that asks the question, is it ok to imitate “the style of”. If Seuss wins this case (which I doubt will happen), it would severely hinder creativity. No more artist would be able to paint “in the style of” Picasso or Warhol...write a book about wizards?.. nope... been done so you can’t do that any more. That movie was filmed using the same style as Michael Bay.... lawsuit.
Then the courts would have to constantly make decisions on whether a certain “style” is different enough which is purely subjective. Just not going to happen.
