This study shows for a large sample of R&D-active manufacturing firms that
collaborative R&D has a positive effect on firms’ patenting in terms of both quantity
and quality. When distinguishing between alliances that aim at joint creation of new
knowledge and alliances that aim at exchange of existing knowledge, the results
suggest that the positive effect on patent quantity is driven by knowledge exchange
rather than joint R&D. Firms engaged in joint R&D, on the other hand, receive more
forward citations per patent indicating that joint R&D enhances patent quality. In light
of literature on strategic patenting, our results further suggest that knowledge creation
alliances lead to patents that are filed to protect valuable intellectual property, while
exchange alliances drive ‘portfolio patenting’, resulting in fewer forward citations.
