Exmark: Reasonable Royalty Damages, Apportionment and Expert Opinions

While Exmark invites a more flexible approach to apportionment, allowing, at least in some cases, a focus on the royalty rate to value the patented invention, the rate analysis itself must be properly supported. Indeed, Exmark serves as a cautionary reminder that any expert opinions on reasonable royalty damages must be closely tied to the facts of the case. Damages opinions that are purely speculative and unsupported by the facts of the case are likely to be found inadmissible. As a result, apportionment approaches will continue to be case-specific, variously focusing on the royalty base, the royalty rate, or a hybrid-model involving both elements.
