Document:
With respect to the § 315(b) issue, the Board acknowledged that Ingenio was served with a complaint alleging infringement of the ’836 patent on June 8, 2001. The Board nonetheless concluded that Ingenio had not been served more than a year before the May 28, 2013, filing of the Petition because the Federal Circuit consistently has interpreted the effect of such dismissals as leaving the parties as though the action had never been brought. The issue before the Federal Circuit was whether the Board erred in interpreting the phrase “served with a complaint alleging infringement of [a] patent” recited in § 315(b) such that the voluntary dismissal without prejudice of the civil action in which the complaint was served “does not trigger” the bar.
The Federal Circuit said that courts must avoid adding conditions to the applicability of a statute that does not appear in the provision’s text. The Federal Circuit noted that Congress specifically addressed the effect of a dismissal of an IPR petitioner’s district court action in § 315(a)(2), but did not include any similar language in § 315(b). Congress also demonstrated that it knew how to provide an exception to the time bar by including a second sentence in the provision: “The time limitation set forth in the preceding sentence shall not apply to a request for joinder under subsection (c).” 35 U.S.C. § 315(b). Similarly, Congress could have chosen to include a variation of the phrase “unless the action in which the complaint was served was later dismissed without prejudice,” but it did not do so. The Federal Circuit rejected the Board’s effort to graft this additional language into § 315(b).
Considering Chevron deference, the Federal Circuit found that the text of the statute answers the question — § 315(b) clearly and unmistakably considers only the date on which the petitioner, its privy, or a real party in interest was properly served with a complaint — there is no need to proceed to Chevron’s second step.
The Federal Circuit rejected the Board’s interpretation of the text of § 315(b) for failing to recognize the statute was agnostic as to the “effect” of the service — i.e., what events transpired after the defendant was served.
The Federal Circuit also rejected the Petitioner’s arguments that, because the claims of the ’836 patent were materially changed during a subsequent ex parte reexamination, neither they nor any other entity was served with a complaint alleging infringement of this patent more than one year before the IPR petition was filed. The Federal Circuit pointing out that unlike reissue, reexamination does not result in the surrender of the original patent and the issuance of a new patent.
