This map represents co-inventorship of priority patents in the areas of nanotechnologies.
There is a collaboration between 2 Functional Urban Areas (FUA) when organisations located within the boundaries of a FUA share authorship of a patent with organisations located in a second FUA.
FUAs (nodes) and collaborations (links) constitute a network. A cluster analysis was realised to identify the type of position of the FUA in their cluster: 'core', 'intermediary' or 'periphery'.

This map has 3 layers (displayed by default):
