Dispute Summary
FreightCar America filed an IPR petition seeking cancellation of all 44 claims of U.S. Patent 8,132,515, asserting that the hopper‑car features were obvious in view of historic rail‑car literature. The petition relies on multiple early‑20th‑century references and expert testimony to demonstrate lack of novelty.
