Classification of technology in 389 subfields | Sciences, technologies and visualizations

Classification of technology in 389 subfields

The global map of technology uses an original classification of technology that distributes all inventions in 389 non-overlapping classes.
This IFRIS classification is based on the well-established WIPO hierarchical classification that distinguishes, at its finest aggregation level, 35 technological fields, these 35 fields, being grouped in 5 technological domains.
The IFRIS classification adds a finer grained level of disaggregation - i.e. below the level of technological field - of 389 technological subfields.

Global Map Of Technologie
Global Map Of Technologie >>

This research presents first a document level global map of technology. In a second place, the technological portfolios of two large industrial corporations are projected on this global map, allowing comparisons that are visually attractive and potentially useful for research, development and innovation policy makers as for research managers within corporations.
