The Invaluable App launched on Android

Invaluable launched the Invaluable app on Android, now available at Google Play Store.

U.S. Utility Patent secured by Invaluable

Invaluable secured a U.S. Utility Patent on live auction bidding console technology that will streamline auction house operations – allowing auction houses to promote, market and advertise upcoming catalogs to multiple marketplaces and see all bidding filter through a single clerking console. We envision a far simpler and more efficient future in which auction houses can upload a catalog to Invaluable and list with all marketplaces. The goal: one listing fee, one upload, one approval process, one registration and one clerk.
