Last week, Judge Nelson of the District of Minnesota decided that further briefing on venue in The Valspar Corp. et al. v. PPG Industries, Inc. was appropriate given the recent TC Heartland decision by the Supreme Court. This decision by Judge Nelson came even though the case was already well past the dispositive motion stage and quickly approaching Markman. The decision was based off of a letter written by defendant, PPG Industries, essentially asking the Judge to recognize the unique situation created by TC Heartland. In the letter, PPG stated that “[t]his is not a discretionary question as to what venue is ‘convenient’…rather, this raises a new question as to whether venue is proper in Minnesota.” PPG went on to address the Rule 12 waiver issue by citing cases stating that a defense cannot be waived “which did not exist when [a party] makes its first defensive move.”
