Critical and conflict materials (CCMs) are providing an important material infrastructure for recent technological shifts. Relying on text analysis of US Patent and Trademark Office (USPTO) data, this exploratory study examines the technological and geographical linkages between technological paradigms and selected CCMs. Our descriptive analysis finds evidence of a clear association between information and communication technologies (ICTs) and CCM intensity over time, and of a striking resource–technology divide between value-creating and -extracting activities across the Global North and the Global South and their regions. The paper emphasizes the need for a more critical, spatially sensitive approach to studying resource-based technological change to expose its uneven development consequences.
