The jury made no decision on fair use, and the judge declared a mistrial on that portion of the case. His subsequent ruling moots the whole issue (no copyright, no infringement) --- but if that ruling were reversed, there would be a new trial on at least fair use. And IIRC, Google has indicated that they'd want a new trial on all copyright matters at that point.
