| Popis: | 93 This study modifies the methods presented by Brockhoff(1992) and Ernst(1998) to analyze patent portfolios. To analyze patent portfolios, the previous methods used two aspects: company and technology. In the aspect of company, this study use six indicators instead of five indicators proposed in the previous methods to evaluate the patent activities and quality. Furthermore, this study use factor analysis and cluster analysis to divide and confirm patent position of important companies in Magnetic Random Access Memory (MRAM) industry. In the aspect of technology, this study introduces an emerging method, called text mining, to clarify the technological fields and to replace the manual classification in previous methods. The technological fields are classified based on the similarity between patent documents. After classification, patent performances of each technological field is analyzed and compared according to the commonly used patent indicators proposed by CHI Research Corporation. Based on the results using the modified method, this study analyzes the patent performance, R&D focuses and technological ability of important companies in MRAM industry. |
