The Federal Circuit's Tuesday ruling in Stauffer v. Brooks Brothers permits qui tam relators to sue over mismarked patents, even when they have not personally been injured; together with an earlier decision that the $500 fine for violating the statute is calculated per mismarked item, rather than per incident, exposes manufacturers to potentially billions of dollars of liability. Naturally, a number of plaintiffs' lawyers are engaging in rent-seeking. [WSJ; Reuters; Bloomberg]
