Being There : Patent Class Contrast and the Impact of Technological Innovations
نویسندگان
چکیده
We build on recent research on the effects of category contrast to gain new insights on why some patents have more impact than others. Analyzing forward citation patterns of almost three millions patents of USPTO, we show that the distinctiveness of the class to which a patent belongs affects the number of citations received in two ways: first, patents classified in high-contrast classes, on average, exhibit a higher impact compared to those belonging to low-contrast classes; second, the impact of recombinant patents is reduced when they belong to a high contrast class. The paper elaborates on the theoretical link between the sociological literature on categories and innovation research.

متن کاملNot All IT Innovations Are Equal: Evidence from Medical Device Patents
We develop a patent analysis approach to discover types of IT innovations and examine their technological and economic impacts. Our empirical investigation is based on 73,120 patents in the medical devices industry filed between 1996 and 2005. Rather than relying on pre-established classifications of IT innovations, we apply textual analysis to patent abstracts and map the extracted IT innovati...

متن کاملWhat do Inventors Patent
Legal disputes, such as the Blackberry case, suggest that patent rights may become vital to the economic survival of even the most successful innovations. Although it is obvious that inventors do not choose to patent all their innovations, what or why they patent is poorly understood. This paper introduces a new data set of more than 7,000 American and British innovations at three world’s fairs...
