Pandrol USA v. Airboss Railway Products
In sum, this court affirms the district court’s decision that the ’046 patent’s specification satisfies the written description requirement of § 112. In addition, this court affirms the district court’s decision to exclude Mr. Young’s testimony in light of the doctrine of assignor estoppel and because Airboss did not produce a timely expert report under FRCP 26(a)(2). Finally, the district court did not abuse its discretion in refusing to entertain Airboss’s obviousness challenge.
