The goal is to tackle anew the main problems encountered in using patent data in economic research, namely, the large variance in the value of patents, and the difficulties in matching patents with economic categories. The first is addressed with the aid of patent citations, the second with computerized search techniques for large databases. The proposed solutions are applied to the case of Computed Tomography (CT) Scanners, a pathbreaking innovation in medical technology. The main findings are that patents weighted by citations are highly correlated with the value of innovations, and that important innovations generate further innovative activity (R&D), and hence bring about down-the-line patents

We propose an empirical strategy for estimating competition in innovation markets based on a model of creative-destruction. Our method relates firms' market return on equity to information about patent citation patterns. Two innovations we introduce are using daily abnormal stock returns rather than annual measures of Tobin's q and creating citation patterns related to the area of science a firm patents in as represented by the detailed patent classification system. We find that firm's market value increases when its patent portfolio is cited and when there are citations to an area of science in which their patent portfolios are prominent. Holding this effect constant, we find that citations from patents in the same area of science tend to reduce market value. We interpret these findings as consistent with more citations indicating more valuable intellectual property but citations from competing technologies decreasing its value.

"What is driving the remarkable increase over the last decade in the propensity of patents to cite academic science? Does this trend indicate that stronger knowledge spillovers from academia have helped power the surge in innovative activity in the U.S. in the 1990s? This paper seeks to shed light on these questions by using a common empirical framework to assess the relative importance of various alternative hypotheses in explaining the growth in patent citations to science. Our analysis supports the notion that the nature of U.S. inventive activity has changed over the sample period, with an increased emphasis on the use of the knowledge generated by university-based scientists in later years. However, the concentration of patent-to-paper citation activity within what we call the "bio nexus" suggests that much of the contribution of knowledge spillovers from academia may be largely confined to bioscience-related inventions"--National Bureau of Economic Research web site.

Not all innovations are equal. Though recent economic literature on the evaluation of technological change acknowledges this reality, actual evaluation methods suffer from numerous limitations. Technological Innovation Index uses patent citation analysis to highlight the enormous variation in the characteristics, importance and evolution of technology over time and outlines a set of sophisticated tools for its analysis. Prominent among them is ?Patent Importance Technology Factor? (PITF), an improved algorithm for the calculation of patent impact using citation scores. The usefulness of PITF is illustrated by examining the evolution paths of high-impact innovations. The methods proposed have important implications for the measurement of technological change and would be of interest to a wide range of patent specialists, including economists, technology evaluators, finance and law professionals."The work of Fredrick Pachys signifies a further and important contribution towards our ability to quantify in a meaningful way the "importance" or "impact" of patents. There is no question that in this era of accelerated innovations we need better indicators of the significance of patents, both for academic purposes and for policy - PITF is a milestone in that direction."Prof. Manuel TrajtenbergTel-Aviv University, Author of "Patents, Citations and Innovations: A Window on the Knowledge Economy" (with Adam Jaffe).
