This article compares the relationship between patent quality and patent value in discrete and cumulative innovation. Using factor analysis and a set of various commonly used patent quality indicators including claims, citations and family size, we build a quality factor jointly driving all...

This article explores what factors determine the decision of a patent pool to accept new inputs. We propose a dynamic analysis of 1337 U.S. patent inputs into 7 important pools. This analysis highlights a trade-off between firm and patent characteristics as the determinants of inclusion of...

This paper analyzes empirically the value - as measured by patent citations - of a set of 1363 essential patents belonging to 9 different patent pools. We find that pooled patents receive more cites than control patents having the same characteristics but not included in a pool. This difference...

The development of formal ICT standards is a loose form of collaborative innovation: firms first develop rival technologies, some of which are then eventually selected in the standard. Against this background, firms often use informal consortia to define a clearer technology roadmap ahead of the...

This article investigates the interplay between formal standards, essential patents and informal industry alliances such as consortia and patent pools. Building upon more than 6.200 declarations of essential patents to major international Standard Development Organizations (SDO), we investigate...
