“…Based on this, for the development of innovation, it is necessary and important to study the innovation elements in the process of technology innovation. Based on the collecting and analyzing on the relevant knowledge and information of the ontology, environment and process of innovation [11][12][13], in the way of document retrieval and patent mining and through implementing the matrix and semantic analysis for the innovative knowledge, innovative mechanism and innovative principles in multiple innovation areas, this paper finds that innovation changes with the change of innovative elements, structure, system, environment, boundary conditions, time and space changes parameters. At the same time, the new model is constantly generated and transformed into a new form.…”

Abstract. In order to improve the efficiency of innovation, the process of technology innovation has caused the attention of experts and scholars day by day. But in the process of technology innovation, the research on the extraction and classification of innovation elements needs to be further specific and systematic. Based on the full research on the innovation activities and innovation elements in many innovative fields, this paper elaborates the general process of the formation of innovation principle, and clusters innovation elements in many fields to form nine innovation dimensions, and then segments each innovation dimension into several sub dimensions of innovation. This paper aims to provide theoretical support for the research of innovative methods, and provide help for improving the quality and efficiency of innovation.

“…Jensen and Webster (2006) used patent data to study the relationship between firm size and patent intensities in Australia. Bessen andMaskin (2009) andGeradin et al (2011) found that the number of patents is highly correlated with firm size, and larger companies tend to treat patents as a competitive niche (Kim et al 2008;Blind et al 2009;Trippl, Maier 2010).…”

Abstract. Many recent studies have discussed the appropriateness of various patent measurement indicators, as well as the differences in the positioning of patented technologies, while there is little discussion on the risk transmission of enterprises when faced with infringement litigation. This study used the bivariate EGARCH (Exponential Generalized Autoregressive Conditional Heteroskedasticity) model with DCC (Dynamic Conditional Correlations) to investigate the dynamic risk transmission of patent litigation between market competitors in the smartphone industry. Empirical results revealed that when facing lawsuits from market challengers, the market leader faces fewer risks when handling patent infringement litigations. In addition, the risk reactions of competitors during patent wars may widely differ. Investors should consider the patent infringement litigations when measuring the dynamic risks of share prices, and determining the optimal configuration of asset portfolios in response.

“…Jun and Park [11] also defined the representative technology of the clusters as the most frequent IPC. Kim et al [13] suggested the patent map of a semantic network based on the terms' frequency and filing data. However, there are some limitations to defining technology because the definition of technology with unfiltered terms or IPC frequency could contain noise and false or unspecific terms.…”

“…This was followed by principle component analysis (PCA), which was adopted to reduce the high dimensionality of patent data and to map the patent documents. Kim et al [13], Jun et al [14] and Jun [11] developed the technology clusters using k-means clustering based on Euclidean distance, and Jun et al [15] formed technology clusters using k-medoids clustering. However, there are some limitations-PCA is inefficient for patent mapping in terms of visualization; k-means clustering and k-medoids clustering necessitate the determination of the number of clusters beforehand, and the results of k-means clustering are greatly influenced by the value of the initial cluster center.…”

This study explores technology clusters through patent analysis. The aim of exploring technology clusters is to grasp competitors' levels of sustainable research and development (R&D) and establish a sustainable strategy for entering an industry. To achieve this, we first grouped the patent documents with similar technologies by applying affinity propagation (AP) clustering, which is effective while grouping large amounts of data. Next, in order to define the technology clusters, we adopted the term frequency-inverse document frequency (TF-IDF) weight, which lists the terms in order of importance. We collected the patent data of Korean electric car companies from the United States Patent and Trademark Office (USPTO) to verify our proposed methodology. As a result, our proposed methodology presents more detailed information on the Korean electric car industry than previous studies.
