This study was conducted to evaluate the technical value of 19 intellectual property rights held by the Korea Research Institute of Bioscience and Biotechnology, and the purpose of this valuation is to promote commercialization by acquiring the technology transfer or exclusive license for the intellectual property rights. This study examines the theoretical and practical aspects of the valuation methods and procedures of the income approach that are useful for valuing intellectual property. Assuming that bioscience and biotechnology firms receive license transfer of intellectual property held by a foreign company, the valuation analysis of intellectual property based on the profit approach is based on business plans and financial statements of domestic companies. After calculating the operating profit from the gross profit of the company in detail, the corporation tax and the capital cost are taken into account and the depreciation cost is increased or decreased to calculate the excess profit and multiply the present value by the present value. We propose an income approach model and a case analysis to obtain the ultimate value of intellectual property by multiplying the contribution by this factor. It is not easy to predict future cash flows and estimate various financial statements, and there is a limit to the possibility that the evaluator will be subject to the estimation of the appropriate discount rate. More detailed and partial complementary research classified by the industry size is to be left as a future study.
