Which Invention Level focuses on creating the underlying operating system API for mass adoption?

Answer

Platform Invention

The hierarchy of invention involved in creating deployable contact tracing systems distinguishes between several layers. The 'Platform Invention' specifically describes the development work focused on creating the necessary underlying Application Programming Interface (API) that allows for mass adoption across mobile operating systems. In the context of the COVID-19 response, this level is exemplified by the Google/Apple EN System, which provided the essential technological foundation upon which national health ministries built their own specific applications (Application Invention).
