| Summary: | 碩士 === 中原大學 === 企業管理研究所 === 95 === In knowledge economy era, the intangible asset gradually becomes the valuable asset of the enterprises. The intangible asset and the Intellectual Property Rights (IPRs) unify closely in together. IPRs include patent, copyright, trademark, lay-out and trade secret. Patent is the major income of the intangible asset. Patent rights can protect the result of research and development. If enterprise wants to gain a new technology by buying or licensing from patents, it is an important issue to choose the valuable and suitable patent. This research develops a multi-dimension hierarchical system to evaluate the patent and apply to the nanometer titanium dioxide technology. And the alternative of this evaluating system is using patent analysis method by USPTO (United States Patent and Trademark Office) database. Therefore, this study uses fuzzy integral to calculate the evaluating value of aspects and alternatives (patents). The results show that Business Environment (B) is the most important factor and Patent’s aspect (D) is the lattermost concerned to evaluate patents. In Patent’s aspect (D), US 5,616,532 performed better than US 5,755,867 in quantification’s criteria. We first discuss the patent of US 5,755,867; all of companies think it performed the best in Business Environment (B) aspect and secondary is in Technology (A). However, one of the companies thinks it performed the best in Technology (A) and secondary is in Risk (E). About the patent of US 5,755,867, all of companies think it performed the best in Technology (A), but one of the companies thinks it performed the best in Risk (E). In conclusion, the results as compared with two patents, all of companies prefer the patent of US 5,755,867, but one of the companies prefers the patent of US 5,616,532. The results show the preference of all aspects and patents. Therefore, the evaluating system that we provide in this research can become a good tool for enterprises to evaluate patents in the future.
