Failure to Apportion Damages on Claim-by-Claim Basis Does Not Render Expert’s Opinion Unreliable

The court denied defendant's motion to exclude the testimony of plaintiffs' damages expert regarding a reasonable royalty for failing to apportion damages on a claim-by-claim basis. "Plaintiffs [argue] that [the expert's] opinion is economically justified because he opines that infringing any of the asserted patents would 'have the same economic effect as infringing all of them.' In other words, Plaintiffs lose the same profit whether one patent claim in one patent is infringed, or whether multiple claims in multiple patents are infringed. . . . [T]o the extent that Defendant quarrels with certain factual assumptions made by [the expert] in failing to apportion damages on a claim-by-claim basis, those disputes go to the weight that his testimony should be given. . . . [His] reasonable royalty opinion need not be excluded simply because he did not apportion damages on a claim-by-claim basis."
