This study is intended to suggest the necessity to establish the valuation system for software (SW) copyrights and the related issues to it through the valuation of intellectual property rights, which has recently become increasingly important. As the appraisal of development expense computation has limitations in conducting valuation for copyrights, the necessity for the valuation of practical SW copyrights is proposed in this study. In addition, considering issues arising from the valuation system for patent rights, a brief approach for the establishment of the valuation system for SW copyrights is outlined here

Software compliance is an essential process when Open Source Software is included in software development to avoid such as license violation issue. However, analyzing quite big software which involves many developers requires enormous time and hard difficulty. To resolve these kinds of problem, SPDX formalizes and standardize the metadata about the software package. When the use of SPDX is activated, software package analysis would be simple and could contribute fair Open Source Software distribution. In this paper, we develop blockchain based SPDX distribution platform which fulfills the requirement of SPDX lifecycle to provide SPDX database which does not depend on particular centralized service but serve as distributed ledger and control by user's certification and their purpose. Moreover, to contribute invigoration of blockchain based SPDX distribution platform, we develop SPDX document generation plug-in for integrated development environment such as Visual Studio.

Copyright evaluation is a work for seeking the similarity between original product and suspected one. Generally, objective materials of both should be submitted to the official authority, but suspected one be declined with uncomfortable status. Especially in case of related to hardware material, such as circuit diagram, PCB gerber file, and elementary part list, there is only hand over a market released final system. In this paper, we show a case study for guideline threshold to decision of evaluation for hardware materials.
