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...

This article takes a critical look at recent developments in university technology licensing. It argues that the Bayh Dole Act vastly underestimated the difficulty in licensing advances made within universities. First, these developments are often far upstream. Second, university technology...

Around 300 B.C., a Greek mathematician — Euclid — discovered a theorem on which modern geometry and a fundamental algorithm is based. The Euclid’s theorem represents a method for calculating the greatest common divisors between two integers. Since 300 B.C., both Euclid’s Theorem and...

After an introduction into the principle data and methodology, this study starts by providing a quantitative overview of the general features of standard essential patents (also called SEPs). It considers the occurrence of essential patents, how their existence has developed over time, and how...

A popular theory is that it may be sufficiently difficult to reach agreement on patent license terms that holdup in development may occur. Early U.S. radio development is widely believed to provide an empirical example of such holdup during 1905-1920, with numerous allegations of an impasse in...

This Article demonstrates that all intellectual property defenses fit into three conceptual categories: general, individualized, and class defenses. A general defense challenges the validity of the plaintiff’s intellectual property right. When raised successfully, it annuls the plaintiff’s...

We have examined all the US patents (444) issued to homegrown Indian pharma and pharma biotech firms. Most (425, 95%) patents are pharma patents not biotech (19). Also, only 11 patents have been cited ten times or more. This data provides one snapshot of the biotech industry in India today. It...

The Italian and European regulatory framework for patents would benefit from further improvements in order to foster dynamic competition between Italian firms. At the national level the exclusive allocation of the right to patent inventions to universities, rather than to researchers, would...

A current refrain in patent policy discourse is that “overly-broad” patents of “dubious validity” retard innovation. We briefly review expressions of the thesis to show that they reduce to the allegation that disagreements over enforceable patent scope and/or validity harm innovation....
