New article of Dr Georg von Graevenitz at Vox.EU.

Dr Georg von Graevenitz – Senior Lecturer in Quantitative Methods at Queen Mary University of London, School of Business and Management –  has published a new article at VoxEu.Org, the CEPR online Policy portal aimed to promote research based policy analysis and commentary.

The article -co-authored with Bronwyn H.Hall, Professor Emerita of Economics at UC Berkeley, and Christian Helmers, Assistant Professor at the Economics Department at Santa Clara University- analyses the effects of Patent Thickets (patents belonging to many companies protecting overlapping technology) on Innovation.  

“Patent filings have proliferated globally in recent years. While some may see this as a direct consequence of increased innovation, this column uses evidence from the UK to show that patent thickets reduce innovation. Patent thickets decrease entry (i.e. first time patenting in an area) by 20%, which is substantial bearing in mind that the average probability of entry into a technology area is only about 1.5%.”

The complete article can be read at Vox.EU.


More information about Patent Thickets, and their effects on innovation, can be found on the CGR Working Papers: “Technology Entry in the Presence of Patent Thickets” and “Conflict Resolution, Public Goods and Patent Thickets”.
