Knowledge Spillovers from Renewable energy Technologies, Lessons from patent citations (2017, background): “In addition, these technologies have high social value for society: they receive a large number of citations and find applications in a large set of diverse fields - two characteristics of highly valuable innovations (Lanjouw and Schankerman, 2004; Popp and Newell, 2012).”
Identifying Technology Spillovers and Product Market Rivalry (2005, neutral): “23See also Jaffe (1986), Lanjouw and Schankerman (2004), and Hall et.”
Patent statistics: A good indicator for innovation in China? Patent subsidy program impacts on patent quality (2015, background): “Another approach is to quantify the breadth of patent claims by counting either the number of claims (Lanjouw & Schankerman, 2004) or the length of the primary independent claim.”
Do tax incentives for research increase firm innovation? An RD design for R&D (2016, neutral): “Finally, counting citations made by subsequent patents are a popular method of accounting for patent value (Lanjouw and Schankerman, 2004; Hall et al., 2005).”
Where does energy R&D come from? Examining crowding out from energy R&D (2012, background): “Related work includes Link (1982), who finds evidence that part of the measured decline in productivity R&D in the 1970s occurred because more R&D was directed toward environmental research, whose benefits (e.g. a cleaner environment) were not measured in traditional market outcomes. Using macroecon”
The firm-level employment effects of innovations in high-tech US manufacturing industries (2011, methodology): “We are not the only ones to apply PCA to studies into firmlevel innovation however—this technique has also been used by Lanjouw and Schankerman (2004) to develop a composite index of ‘patent quality’ using multiple characteristics of patents (such as the number of citations, patent family size and”
Inventors and invention processes in Europe: Results from the PatVal-EU survey (2007, background): “Also, Lanjouw and Schankerman (2004) show that it is hard to distinguish whether patent claims are a measure of patent scope, degree of protection or of value.”
Knowledge Maturity and the Scientific Value of Innovations (2017, methodology): “In addition, we controlled for the number of claims per patent (Claims) (Lanjouw & Schankerman, 2004), references to scientific knowledge (SciKnowledge) measured by the number of nonpatent references each focal patent cited (Narin, Hamilton, & Olivastro, 1997), and number of forward self-citations…”
