Personal collaborations are most effective.
Knowledge transfer is relatively straightforward.
It is the classical role of the universities. The transfer takes place through the open literature and through personal collaborations. An individual scientist in industry is the recipient, and patent considerations are not involved. Membership in industrial consortia can facilitate transfer for members of the consortia. From the industrial side, the best guaranty of using the most recent academic advances is to have on its staff experts doing research in the relevant areas.
