On January 12, 2018 in Exmark Manufacturing Co. Inc., v. Briggs & Stratton Power Products Group, LLC, the Federal Circuit once again addressed the issue of apportioning damages, an area of the law that continues to evolve. The parties in Exmark are competitors in the commercial lawn mower market. The patent-in-suit related to a lawn mower with an improved “baffle” that more efficiently directed air flow and grass clippings when the mower was operating. At the conclusion of the jury trial, the defendant’s mower was found to infringe and the jury awarded the plaintiff over $24 million in damages. On appeal, the Federal Circuit affirmed the method of apportionment utilized by the Plaintiff’s expert, but rejected the expert’s application of that method.
