Because of concerns about awarding patents to unproven inventions, prophetic examples are viewed with greater skepticism in Europe (8), Canada (9), Japan (10), and China (11). However, because patents with the same contents are often filed in multiple regions, prophetic examples originating in U.S. applications will often be present in applications filed in other jurisdictions. Further, because patent offices and examiners in those countries commonly read and cite patents from other jurisdictions, countries skeptical of prophetic examples still feel their effects.
