Analysis of patent documents with utility mining: a case study of wind energy technology

Abstract

Purpose This study aims to propose a novel approach based on utility mining to find the associations among wind energy technologies. Design/methodology/approach The proposed approach uses patent documents and utility mining. Associations among wind energy technologies have been evaluated to show how the proposed approach works in practice. Findings Determining the relationships between wind energy technologies provide essential information to investors and decision-makers. Therefore, a real-life case study of wind energy technology is performed to show how the proposed approach works in practice. The proposed approach founds technology classes associated with wind energy technology. Furthermore, the strongest associations among technologies are also obtained by the proposed approach. The results of the case study show that the proposed approach can be easily used in practice. The maximum size of itemsets is 18-level itemsets. Y02E and F03D cooperative patent classification (CPC) codes appear on all itemsets. As the technologies of Y02E and F03D are directly correlated, they will be mutually developed in the future. Additionally, the number of patent corresponding to Y02E and F03D CPC codes are 7,494 and 6,577, respectively. Originality/value This is the first study that applies the utility mining-based approach to patent documents. Different levels of importance among technologies based on patent citations and the number of repetitions of each technology class are considered in the proposed approach.

An optimized model for open innovation success in manufacturing SMES

“…In terms on research limitations, three main restrictions including: (1) Lack of integrated software to perform calculations of fuzzy DEMATEL technique increases the time of calculations and the probability of errors in calculations. (2) The impossibility of checking the accuracy of the answers is another limitation in studies which data is formed according to the respondents' opinions. (3) Using the concept of OI in MSMEs in developing countries such as Iran is considered as a new approach and this makes it not only difficult to find competent people to answer research questions, but also different dimensions are still needed for study.…”

“…However, in OI paradigm, which was first introduced by Henry Chesbrough in 2003 [5,47], knowledge is transferred easily from inside and outside of the organizations [25,28]. Thus, firms cannot rely on their internal research and they can benefit from purchasing innovations or licenses from other companies if necessary [2]. In fact, OI is a process, in which external ideas are welcomed as well as internal ones [29] and the borders between organizations and environment are penetrable, which facilitates knowledge transfer [33].…”

“…In OI model, companies must discover new opportunities beyond their borders and their limited resources [43] by cooperation with other organizations including universities, suppliers, partners, customers, rivals, and internal usage of IP or patent permissions [1,2,40]. Exploring new opportunities to achieve new knowledge and technology [30], especially in Small and Medium Enterprises (SMEs) helps overcoming innovation obstacles [31,35,41], since they are not able to do independent research on account of their limited resources, size and target market [32,42].…”

Identifying Firm Significance and Positions in the Patent Innovation Based on Centrality Measures’ Clustering Approach

“…Patent data can be analyzed to identify multiple dimensions of an innovation landscape. Using patent analysis, previous studies have identified trends and trajectories of evolving and established technologies [3][4], technology convergence and divergence, and firm innovation capabilities. Patent citation analysis is employed to assess the knowledge flow [5][6], as well as knowledge providers and absorbers [7] across the technology trajectory.…”

Technological patterns in the wind power industry: a study based on patent deposits

“…• Development of new analysis methodologies using patents documents on wind and other renewable energy as application examples (Daim et al, 2012;De Rassenfosse et al, 2013;Altuntas & Gök, 2020).…”
