Patent Marking Burden of Production on Alleged Infringer, Burden of Persuasion on Patentee

In Arctic Cat Inc. v. Bombardier Rec. Prods., after unsuccessfully defending a patent infringement lawsuit, Bombardier Recreational Products, Inc. (“BRP”) appealed the district court’s denial of its motion for judgment as a matter of law. BRP argued that the asserted claims of U.S. Patent Nos. 6,568,969 (“the ‘969 patent”) and 6,793,545 (“the ‘545 patent”) were obvious, that patentee Arctic Cat failed to mark patented products, that the jury based its royalty award on improper expert testimony, and that BRP did not willfully infringe the asserted claims. BRP also appealed the district court’s award of treble damages and the ongoing royalty to Artic Cat… While the burden of persuasion under the statute is always on the patentee… the alleged infringer who challenges the patentee’s compliance with the marking statute has the initial burden of production because placing the burden on the patentee “could lead to a large-scale fishing expedition.”
