Traditionally patents are seen as the gold standard for intellectual property protection. But, in line with empirical findings that secrecy is considered more important for appropriating returns, recent theories predict that firms keep their most important inventions secret. This article...

This paper utilizes a data set of over 208,000 U.S. patents applied for between 1975 and 2010 to study development of strategic patenting over time and across industries. With received citations as a measure of patent social value, we use data envelopment analysis to estimate firm-level relative...

The intellectual property system does not seem to drive the rate of innovation in the market for vegetable varieties. Drawing on a unique data set of all plant patents, plant variety protection certificates, and utility patents among 42 vegetable varieties, this short paper examines the...

This paper compares reward systems to intellectual property rights (patents and copyrights). Under a reward system, innovators are paid for innovations directly by government (possibly on the basis of sales), and innovations pass immediately into the public domain. Thus, reward systems engender...

There is increasing concern that overlapping patents in the field of genetics will create a costly and legally complex situation known as a patent thicket, which, along with the associated issues of accumulating royalty payments, can act as a disincentive for innovation. One potential means of...

Open innovation is the subject of increased scholarly debate. A lot of attention has thereby been paid to firm-centered open innovation, characterized by a for-profit motive and the interplay between patents and contracts, resulting in restricted openness. Inspired by the increasing call for...

Concerns have been raised that the upsurge of 3D printing technology would disrupt the patent system. The central question the present paper aims to address is whether and to what extent the emergence of 3D printing technology indeed urges us to rethink patent law. The paper splits up this...

We discuss various economic aspects of different types (or taxa) of “patent thickets” identified in a companion article co-authored by one of us. We analogize patent thickets to “tangible input thickets” (in which manufacturers of complex products need a large number of different...
