(c) Filing Deadline.—A petition for a post-grant review may only be filed not later than the date that is 9 months after the date of the grant of the patent or of the issuance of a reissue patent (as the case may be).

"(A) whether a stay, or the denial thereof, will simplify the issues in question and streamline the trial;
