| Summary: | 博士 === 中華大學 === 科技管理學系(所) === 97 === This study aimed at the basis of patent law and proposed a valuation model for the monetary legal value of patents. The damage awards of patent infringement lawsuits were deemed to be the legal value of patents. 65 effective samples of patent infringement lawsuits were extracted from 4,289 patent related lawsuits in U.S. district courts of Delaware, California and Texas. 17 patent indicators were summarized to describe quantitative dimensions of a patent. For discussing the linear and/or the non-linear relationships of the 17 patent indicators and the damage award, quantitative approached including the linear regression analysis, the multi-regression analysis, the factor analysis, the gray relational analysis, and four kinds of artificial neural networks were applied. It is therefore to construct the patent valuation model via these approaches. The proposed valuation model was validated to have the predictive power by error analysis. The valuated damage award of the patent was also constructed to be the integrated evaluator by z-score transformation. The integrated evaluator improved traditional patent valuation models. The proposed patent valuation model accommodated to valuate the possible damage award or to negotiate the settlement fee in disputing patent infringement lawsuits. It also contributed to patent transaction, patent licensing and hypothecation of intangible assets, etc.
