“I agree with Patent Owner that the Petition is barred by § 321(c). Section 321(c) provides that “[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).” Joinder is authorized under 35 U.S.C. § 325(c), which provides that “[i]f more than 1 petition for a post-grant review under this chapter is properly filed against the same patent and the Director determines that more than 1 of these petitions warrants the institution of a post-grant review under section 324, the Director may consolidate such reviews into a single post-grant review.” Notably, the statutory authorization for joinder under § 325(c) does not provide an exception to the nine-month statutory bar, as it requires any petition considered for joinder to be “properly filed,” i.e., to meet the statutory filing requirements including the nine-month filing deadline recited in § 321(c). Petitioner argues that I have broad discretion to promulgate rules and permit exceptions, such as here where institution would increase efficiency. See Reply 2–3. I agree that my institution discretion is broad. But § 325(c) provides no exception to the time period in which a petition for post-grant review may be filed.1 The board rule on which Petitioner relies cannot override a clear statutory requirement, and Petitioner does not point” slip op. at 3
