R & D and the patent premium by Ashish Arora( Book )

11 editions published between 2002 and 2003 in English and held by 45 WorldCat member libraries worldwide

We analyze the effect of patenting on R&D with a model linking a firm's R&D effort with its decision to patent, recognizing that R&D and patenting affect one another and are both driven by many of the same factors. Using survey data for the U.S. manufacturing sector, we estimate the increment to the value of an innovation realized by patenting it, and then analyze the effect on R&D of changing that premium. Although patent protection is found to provide a positive premium on average in only a few industries, our results also imply that it stimulates R&D across almost all manufacturing industries, with the magnitude of that effect varying substantially
Firm size and R & D intensity : a re-examination by Wesley M Cohen( Book )

9 editions published in 1987 in English and held by 23 WorldCat member libraries worldwide

Using data from the Federal Trade Commission's Line of Business Program and survey measures of technological opportunity and appropriability conditions, this paper finds that overall firm size has a very small, statistically in- significant effect on business unit R & D intensity when either fixed industry effects or measured industry characteristics are taken into account. Business unit size has no effect on the R & D intensity of business units that perform R & D, but it affects the probability of conducting R & D. Business unit and firm size jointly explain less than one per cent of the variance in R & D intensity; industry effects explain nearly half the variance
Protecting their intellectual assets : appropriability conditions and why U.S. manufacturing firms patent (or not) by Wesley Marc Cohen( Book )

13 editions published in 2000 in English and held by 18 WorldCat member libraries worldwide

Based on a survey questionnaire administered to 1478 R & D labs in the U.S. manufacturing sector in 1994, we find that firms typically protect the profits due to invention with a range of mechanisms, including patents, secrecy, lead time advantages and the use of complementary marketing and manufacturing capabilities. Of these mechanisms, however, patents tend to be the least emphasized by firms in the majority of manufacturing industries, and secrecy and lead time tend to be emphasized most heavily. A comparison of our results with the earlier survey findings of Levin et al. [1987] suggest that patents may be relied upon somewhat more heavily by larger firms now than in the early 1980s. For the protection of product innovations, secrecy now appears to be much more heavily employed across most industries than previously. Our results on the motives to patent indicate that firms patent for reasons that often extend beyond directly profiting from a patented innovation through either its commercialization or licensing. In addition to the prevention of copying, the most prominent motives for patenting include the prevention of rivals from patenting related inventions (i.e., patent blocking'), the use of patents in negotiations and the prevention of suits. We find that firms commonly patent for different reasons in discrete' product industries, such as chemicals, versus complex' product industries, such as telecommunications equipment or semiconductors. In the former, firms appear to use their patents commonly to block the development of substitutes by rivals, and in the latter, firms are much more likely to use patents to force rivals into negotiations
Lens or prism? : patent citations as a measure of knowledge flows from public research by Michael Wayne Roach( Book )

4 editions published in 2012 in English and held by 8 WorldCat member libraries worldwide

This paper assesses the validity and accuracy of firms' backward patent citations as a measure of knowledge flows from public research by employing a newly constructed dataset that matches patents to survey data at the level of the R&D lab. Using survey-based measures of the dimensions of knowledge flows, we identify sources of systematic measurement error associated with backward citations to both patent and nonpatent references. We find that patent citations reflect the codified knowledge flows from public research, but they appear to miss knowledge flows that are more private and contract-based in nature, as well as those used in firm basic research. We also find that firms' patenting and citing strategies affect patent citations, making citations less indicative of knowledge flows. In addition, an illustrative analysis examining the magnitude and direction of measurement error bias suggests that measuring knowledge flows with patent citations can lead to substantial underestimation of the effect of public research on firms' innovative performance. Throughout our analyses we find that nonpatent references (e.g., journals, conferences, etc.), not the more commonly used patent references, are a better measure of knowledge originating from public research -- National Bureau of Economic Research web site
What makes them tick? : employee motives and firm innovation by Henry Sauermann( Book )

5 editions published in 2008 in English and held by 2 WorldCat member libraries worldwide

Abstract: We examine the impact of individual-level motives upon innovative effort and performance in firms. Drawing from economics and social psychology, we develop a model of the impact of individuals' motives and incentives upon their innovative effort and performance. Using data on over 11,000 industrial scientists and engineers (SESTAT 2003), we find that individuals' motives have significant effects upon innovative effort and performance. These effects vary significantly, however, by the particular kind of motive (e.g., desire for intellectual challenge vs. pay). We also find that intrinsic and extrinsic motives affect innovative performance even when controlling for effort, suggesting that motives affect not only the level of individual effort, but also its quality. Overall, intrinsic motives, particularly the desire for intellectual challenge, appear to benefit innovation more than extrinsic motives such as pay
