In what will be welcome news in the offices of general counsel around the country, on June 10 the Court of Appeals for the Federal Circuit released its opinion in Pequignot v. Solo Cup Co.

The decision likely deals a mortal blow to what was a burgeoning cottage industry of patent marking “trolls” filing qui tam suits for false patent marking. A huge increase in the filing of such suits arose in the wake of The Forest Group v. Bon Tool, 590 F.3d 1295 (Fed. Cir. 2009), decided last December.
