The United States Supreme Court decided earlier this year that a 1957 opinion is still valid and still limits venue choices for patent infringement actions under 28 U.S.C. § 1400. See TC Heartland LLC v. Kraft Foods Group Brands LLC, 581 U.S. ___ (2017) (citing Fourco Glass Co. v. Transmirra Products Corp., 353 U.S. 222, 226 (1957)). In its extensively-covered TC Heartland decision issued in May, the Court held that “[a]s applied to domestic corporations, ‘reside[nce]’ in § 1400(b) refers only to the State of incorporation,” where the accused infringer has a “regular and established place of business” in the venue. While framed as merely confirmation of precedent from the 1950s, many practitioners and commentators viewed this decision as a dramatic change in the patent litigation landscape.
Since TC Heartland came down, lower courts have applied the new paradigm in differing ways. As trends have developed in recent months, we thought it useful to provide a sampling of the various approaches to venue issues post-TC Heartland. These issues include, for example, whether defendants who did not contest venue prior to the TC Heartland decision waived the defense of improper venue because the case was—or was not—an “intervening change” in the law, and how to assess whether a defendant has regular and established place of business in a particular venue.
