In a report and recommendation issued Tuesday, August 15, 2017, a magistrate judge in the Eastern District of Texas stated that failure to provide a patent examiner with a copy of a relevant post-grant review (PGR) institution decision does not make a patent unenforceable for inequitable conduct.
In Oil-Dri Corporates of America v. Nestle Purina Petcare Company, the court recently held that a defendant who has filed a parallel inter partes review (IPR) petition is estopped from raising invalidity grounds in the district court that were not, but reasonably could have been, raised in the defendant’s IPR petition. Oil-Dri, 1-15-cv-01067 (ILND August 2, 2017, Order). In this case, Purina raised several invalidity arguments in district court, some of which were not raised in Purina’s IPR petition. Id. at 5.

The Supreme Court’s recent holding in TC Heartland settled several points of law: first, 28 U.S.C. § 1400(b) is the “sole and exclusive provision controlling venue in patent infringement actions; second, the broader venue provisions in 28 U.S.C. § 1391(c) are not applicable to patent infringement cases; and third, TC Heartland reversed the Federal Circuit’s decision that reaffirmed VE Holding and held that “the current version of § 1391 does not contain any indication that Congress intended to alter the meaning of § 1400(b) as interpreted in Fourco.” In the aftermath of TC Heartland, there have been inconsistent approaches to the question of waiver and whether the recent Supreme Court decision constitutes new law. Two such decisions are detailed, below.
