知識經濟時代背景下,無形資產為公司競爭優勢的來源。而專利能夠確保公司創新在法律上享有一定時間的壟斷權,為公司最具有專屬性之無形資產,提升公司的經營績效與市場價值。先前有許多研究分析專利與公司市場價值兩者之間的關係,顯少研究探討公司對於專利的終止行為是否能正向影響其價值。欲維持專利的法律地位公司必須定期支付龐大的維護費用,因此若是未適當地放棄一些不再對公司具有價值的專利,可能帶給公司價值負面的影響。有鑑於此研究缺口,本研究將以美國生技公司做為研究對象,以演化理論來解釋公司透過專利申請與終止行為來提升自身價值的動態過程。希望找出能提升公司價值的專利策略,協助公司以及決策者在專利策略的制定。
Patents are important knowledge assets that contribute firms to defend rivals and earn the returns in competitive environment. Additionally, firms can signal their R&D capabilities through patent application and thereby enhance the value perceived by market investors. However, previous studies do not consider firms enhance value from patent expiration. To maintain the legal rights of patents, firms must regularly pay renewal fees which burden R&D investment. A large amount patents may induce stockholders concern about firms’ future cash flow. So firms cautiously expire patents which cannot benefit them anymore is necessary. This study argues that firms should enhance their value from a sequence of patent application and expiration. This study draws on evolutionary theory to explain how firms dynamically proceed with patent application and expiration and thereby improve market value. The result is based on publicly biotechnology firms in U.S. This study hopes to provide useful information for firms to undertake R&D planning.
