Technical Expert Unqualified to Offer Opinion on Apportionment Value​

The court granted in part defendant's motion to exclude the testimony of plaintiff's technical expert regarding apportionment as unqualified. "An apportionment analysis is performed as part of a damages calculation. As such, there is an inherently economic quality to an apportionment analysis. . . . [Plaintiff's expert], with his Ph.D. in computer science and academic and industry experience in hardware and software design and development, is qualified to review the technical information in this case and opine regarding the importance of the various features of the accused products from a technical perspective. However, due to [his] limited experience with economic apportionment, he is not qualified to provide an ultimate opinion with respect to a damages value attributable to the patented invention. . . . [His] opinions . . . may be an input into the damages expert’s opinion about the proper apportionment value, but may not be the final apportionment value itself."
