Samsung's paid expert, Judith Chevalier, a professor of economics and finance at the Yale University School of management, said a reasonable royalty on the five patents -- if they were infringed -- would be approximately $1.75 per device, a total of $38.4 million in total damages. Apple had previously argued that it was owed $40 in damages per device.
She also called Apple's patents "very negligible" in value because they were not mentioned as frequently in customer reviews as other features that are not at issue in the case.
Chevalier also pointed to Apple's accounting for each of its annual iOS software updates since 2009, which Apple pegs between "100+" and "200+" new features at each release, and come in at $10 to $25 per device in deferred revenue. Dividing the number of features, Chevalier claimed you could classify these features, on average, as costing 5 to 25 cents per feature.Following Chevalier's testimony, Samsung rested its defense before starting its own case accusing Apple of infringing on its patents. The trial is expected to conclude and head to jury deliberations sometime next week.
