Last week the Federal Circuit heard oral argument in Ollnova Technologies Ltd. v. Ecobee Technologies ULC, a patent case we have been following because it attracted an amicus brief. In this case, the patent owner, Ollnova, appeals a denial of requested prejudgment interest, and the accused infringer, Ecobee, cross-appeals the lower court’s decisions on jury instructions and multiple issues including eligibility, infringement, damages, and marking. Judges Chen, Stark, and Cunningham heard the oral argument. This is our argument recap.
