Heading: Exclusion of Dr. Sherman’s Expert Report on In-

Text: fringement Kaneka argues the district court abused its discretion in excluding the portions of Dr. Sherman’s expert report regarding the “oxidizing” limitation and denying its ZHEJIANG MEDICINE CO., LTD. v. KANEKA CORPORATION 7 alternative request to supplement its expert report. 3 It argues Dr. Sherman’s report sufficiently embraces the Kingdomway construction of “oxidizing” and “plainly identifies and describes the action taken by ZMC during its manufacturing process that results in oxidation.” Appellant’s Br. 31. As discussed supra, we agree with Kaneka that the district court misinterpreted the Kingdomway construction. The district court required Dr. Sherman’s report to address more than was necessary under Kingdomway. See J.A. 50 (criticizing Dr. Sherman’s report for not addressing whether ZMC’s processes “actually do cause any amount of oxidation, beyond that which occurs naturally, as a result of the microbial cells’ exposure to ambient air”) (emphasis added). We, thus, need not decide whether it would have been an abuse of discretion to exclude Dr. Sherman’s opinions regarding the “oxidizing” limitation under the district court’s initial interpretation of Kingdomway. We also decline to assess Dr. Sherman’s report in the first instance to determine the relevance of his opinions in light of our claim construction conclusions. We leave that question, as well as the question of whether to allow one or both parties’ experts an opportunity to supplement their reports in response to our opinion. 3 Kaneka also appeals several of the district court’s evidentiary rulings unrelated to the court’s grant of summary judgment. Kaneka argues the district court erred in (1) denying its motion to compel test results relating to a different limitation; (2) excluding testimony regarding that limitation; and (3) excluding testimony of its damages expert. Because these issues do not affect the summary judgment entered by the district court, we decline to review them. 8 ZHEJIANG MEDICINE CO., LTD. v. KANEKA CORPORATION
