The Federal Circuit reversed a district court ruling, declaring Crown Packaging's patents invalid under the pre-AIA on-sale bar, despite the detailed price quotation.
Crown Packaging's high-speed necking machine patents were deemed invalid because a detailed quote marked 'subject to written acceptance' was an invalidating offer, not just an invitation.
The court's ruling highlights that in patent law, a price quotation can serve as an offer for sale, triggering the on-sale bar effectively.
Crown's patents protect their innovative horizontal, multi-stage necking machines, which are crucial for the production of beverage cans at high speeds.
