How Important are Noncorporate Patents? A Comparative Analysis Using Patent Citations Data

Research output: Contribution to journalJournal articleResearchpeer-review


This article analyses the innovative performances of noncorporate inventors using patent citations data from the European Patent Office. The results show that inventions patented outside an established corporate framework are on average less ‘important’ than corporate patents, but with large variations across technology classes. Patents applied for by independent inventors, start-ups and corporate firms are of comparable ‘quality’ in emerging technologies. The results also highlight that in these fields noncorporate patents are more ‘radical’ than corporate patents.
