Pactiv, LLC v. Lee presents a question fundamental to all ex parte reexaminations: whether, after the PTO initiates an ex parte reexamination, that proceeding is limited in scope to the question determined to qualify as the “substantial new question of patentability.” The “substantial new question of patentability” identified by the Director included certain prior art references. But the examiner subsequently rejected several of Pactiv’s claims due to wholly different prior art references. There was never any determination under 35 U.S.C. § 303 that these other references raised a “substantial new question of patentability,” nor did the Director issue the order required under Section 304 identifying a “substantial new question of patentability” based on these wholly different prior art references.
