Gilead Sciences, Inc. v. Lee
778 F.3d 1341
Fed. Cir.
2015

Background

  • Gilead filed the application for U.S. Patent No. 8,148,374 (cobicistat) on Feb. 22, 2008; the patent issued Apr. 3, 2012.
  • PTO awarded Gilead 245 days of A-delay and 406 days of B-delay (651 days), then reduced the PTA for overlap (35 days) and for applicant-caused delay (57 days) tied to Gilead’s supplemental IDS filed after responding to a restriction requirement, yielding 559 days total PTA.
  • PTO relied on 37 C.F.R. § 1.704(c)(8) (promulgated under 35 U.S.C. § 154(b)(2)(C)(iii)) to treat a supplemental IDS filed after an initial reply as applicant failure to engage in reasonable efforts to conclude prosecution, warranting reduction of PTA.
  • Gilead challenged the 57‑day reduction, arguing § 154(b)(2)(C) permits reductions only where the applicant’s conduct actually delayed conclusion of prosecution; it sought review under the APA alleging the PTO’s interpretation was arbitrary and contrary to law.
  • The district court granted summary judgment for the PTO; on appeal the Federal Circuit reviewed de novo and applied Chevron deference to the PTO’s statutory interpretation and rulemaking authority.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Whether § 154(b)(2)(C) permits PTO to reduce PTA for applicant conduct that did not actually delay prosecution (supplemental IDS after reply to restriction) Reductions allowed only when applicant behavior actually delayed conclusion of prosecution Congress delegated to PTO authority to define failures to engage in reasonable efforts; PTO reasonably defined supplemental reply after initial reply as a failure regardless of actual delay Court upheld PTO: statute doesn’t require actual delay; PTO’s interpretation permissible under Chevron step two
Whether ejusdem generis or legislative history limits § 154(b)(2)(C)(i) to conduct that causes actual delay Statutory context (the 3‑month example in (ii)) and legislative history show Congress intended to penalize only conduct causing actual delay The statutory text, structure, and enacted legislative history do not limit ‘‘reasonable efforts’’ to only conduct producing actual delay; examples do not narrow the general grant Court rejected Gilead’s textual/legislative‑history arguments and refused to read an actual‑delay requirement into the statute
Whether 37 C.F.R. § 1.704(c)(8) is unreasonable, overbroad, or causes unequal treatment Regulation is overbroad and treats applicants who received restriction requirements differently from those who did not Regulation reasonably accounts for PTO’s tighter response deadlines after § 132 notices (e.g., restriction requirements) and recognizes examiner workload/externalities Court found the regulation reasonable and not arbitrary; differences in treatment are justified by statutory timing constraints
