Outline of Research at the Start

企業のオープンイノベーションへの取り組みを進めるうえで、技術市場の確立は重要な問題である。本研究は、技術市場の一例として特許市場に注目し、特許ライセンスの戦略の実証研究を通じ、技術経営の観点から企業の知的財産権ライセンス戦略及び技術市場のメカニズム（自社技術を外部に公開、または外部技術を自社に取り入れ、等）を明らかにする。

Outline of Final Research Achievements

This project was proposed to anlayze patent licensing. After reviewing prior studies and received advice from practitioners, this project made a comparison analysis of patent bundles that are licensed. It is found patent bundles with high similarity are licensed.
A patent is an exclusive right over new inventions. In this sense, it is an interesting finding that patent bundles with high similarity exist. Future studies may investigate why highly similiar patents exist. Does the patent system not work as it is designed? Is inventing something similar a result of a knowledge creation mechanism? Although this project did not progress as it was originally planned. However, it produced a new research question.

Academic Significance and Societal Importance of the Research Achievements

当初提案した特許ライセンス戦略に関する新たな発見はなかった。しかし、分析の過程で類似性の高い特許の存在を発見した。この発見は社会的には特許制度の運営に関して、又は学術的には知識創造メカニズム解明に関して、今後さらなる研究の必要性を示している。
