“…and Sapsalis et al (2006)), but they might be of a higher scientific value although of a lower market value due for instance to the uncertainty induced by unproven concepts. Third, the inexperience of a patentee with the patent system (Allison et al, 2003) may be the sign of a highly valuable invention (valuable enough to convince a newcomer to enter the patent arena) or of a small invention that did not pass a careful screening prior to being patented. And fourth, the size of the applicant's patent portfolio (Shane, 2001) -included in many empirical models -may reflect the level of experience the applicant has with the patent system and therefore be proportional to the value of his patents, but very large portfolios may denote patentees with a very high propensity to patent, possibly inducing many applications of a lower value to be filed.…”

This paper aims at contributing to the literature on the determinants of patent value. First, it puts forward a new potential class of value determinants in the form of filing strategies (encompassing filing routes and drafting styles). Second, it provides empirical evidence suggesting that these strategies are consistently and positively associated with patent value indicators. The empirical implementation relies on a unique dataset (about 250,000 patents granted by the EPO), which allows running large-scale sensitivity tests. The results reveal that the new determinants this paper puts forward -filing strategies -are the most stable of all. They also underline strong dependencies of several 'classical' results to the dependent variables and sampling methodologies, partly explaining several inconsistencies observed in the literature.

“…To date the empirical analysis of the patent system has been undertaken by economists and some legal scholars. See, e.g., [2,8,13]. Because patents and the citations between them can be conceptualized as a growing network, however, techniques from statistical physics that have been used in the study of complex networks can be usefully applied to the patent citation network [1,14].…”

This paper reports results of a network theory approach to the study of the United States patent system. We model the patent citation network as a discrete time, discrete space stochastic dynamic system. From data on more than 2 million patents and their citations, we extract an attractiveness function, A(k, l), which determines the likelihood that a patent will be cited. A(k, l) is approximately separable into a product of a function A k (k) and a function A l (l), where k is the number of citations already received (in-degree) and l is the age measured in patent number units. A l (l) displays a peak at low l and a long power law tail, suggesting that some patented technologies have very long-term effects. A k (k) exhibits super-linear preferential attachment. The preferential attachment exponent has been increasing since 1991, suggesting that patent citations are increasingly concentrated on a relatively small number of patents. The overall average probability that a new patent will be cited by a given patent has increased slightly during the same period. We discuss some possible implications of our results for patent policy.

“…of Patent Citations Receive has been used as a proxy for evaluating patent value. Although it is far from a perfect indicator [95], it has been widely used for studying the value of patent [96][97][98][99][100][101][102]. However, a 10-year windows is imposed to avoid truncation problem [103].…”

Global Interdependence of Collaborative R&D-Typology and Association of International Co-Patenting

Economic globalization implies a growing interdependence of resources across countries. Technological R&D and cross-border collaboration are often identified as the primary driving forces in the process. This study aims to holistically analyze global landscape of international collaboration and identify influential countries and the interdependencies among countries. A total of 458,381 international patents granted by the United States Patent and Trademark Office (USPTO) from 1976 to 2013 are analyzed and the structure of international collaboration network is created. It is found that highly developed and small countries usually show a higher degree of internationalization. However, emerging countries such as China present high collaborative influences. The highly skewed collaboration distribution indicates significant inequality of internationalization, which is indeed a hurdle to a country's technological mobility. It can be observed that most pairs of interdependent countries are neighboring or even bordering countries because of their similar historical, linguistic and cultural heritages. Several contributions of this study are summarized as follows: (1) this study first proposes the II, IA, II-IA, IA-AA, and II-IA-AA system for classifying international patent; (2) all international patents (38-year time span) from USPTO are examined without sampling; (3) association rule mining is used to evaluate the interdependency of international collaboration; and (4) network structures illustrating 38 years international co-patenting are visually presented.
