“…This means that the basic patent analysis method, with several indicators (patent application, patent priority, patent assignee, and so on), is still the mainstream method of describing and estimating the stage of the technology life cycle. Conversely, some refined analytical methods based on the traditional patent indicators sound vigorous and novel, for example, the patent alert system (PAS), the fuzzy regression of PAS, and function-based patent analysis (Daim et al 2013;Park et al 2013).…”

In terms of technology evolution pathways, patents, articles and projects are the traditional analytical dimensions, particularly patent analysis. Analysis results based on traditional dimensions are used to present the evolutionary stage based on the theory of the technology life cycle (TLC). However, traditional TLC is insufficient to explain the inner driving force of technology evolution; instead, it just describes the process. Promoting ideality degree, one of evolutionary principles in the framework of Teoriya Resheniya Izobreatatelskikh Zadatch, is combined with patent and article analysis, and then a novel three-dimensional analytical method is introduced. In a case study with one curial material and novel technology, graphene attracted the attention of all types of organizations, but the development prospects of the graphene industry are not clear, and its potential abilities and applications should be deeply explored.

“…Patents have been widely used as a variable for measuring "output, technological innovation activity, or the strategy of technology management" [21][22][23][24][25][26][27][28][29][30][31]. They are also seen as one of the data sources that are capable of assessing technological capabilities of competitors [32].…”

Abstract:The chemical industry provides essential goods we use in our daily lives and key ingredients for many diverse industries. On the other hand, their production and use require serious attention while they may be seriously harmful to local air quality. The Clean Air Act (CAA) and its subsequent amendments regulate the emissions of hazardous air pollutants to protect public health and welfare in the U.S.A. since 1970. This study aimed to assess the impact of CAA on the rate of patenting in the chemical industry. With this in mind, basic chemical utility patents were analyzed to detect the effects of CAA on the patenting activities. Subsequent to the fitting of the ARIMA (Autoregressive Integrated Moving Average) model (producing the least square of errors), a significant outlier was detected with the Dixon's r22 Ratio Test. This outlier was the number of patents granted in 1972. Contextual queries in the text of those patent documents have shown that there was a considerable increase in the patents of chemistry which takes the sustainability relevant terms (air, emission, pollution, etc.) into consideration. It was concluded that companies in the chemistry industry adapted themselves very rapidly to the changes and CAA was an important incentive to create novel technologies.

“…Recently, a Social Network Analysis (SNA) on the link information of a patent has been widely used to understand the complicated interactions in technological evolution (Constant, 2002;Devezas, 2005). The SNA of patent data not only explains the complex interdependency among different technologies but also offers some insights on trends in technological interaction and changes by industry (Biju and Soumyo, 2001;Murray, 2002;Phene and Almeida, 2003;Han and Park, 2006;Daim et al, 2012;He and Fallah, 2009;Choi and Park, 2009;Lee et al, 2009a;No and Park, 2010;Lee et al, 2009bLee et al, , 2010Gress, 2010).…”
