選擇權於專利技術鑑價分析與工程應用實例

指導教授 : 楊宏智

摘要


傳統進行專利技術鑑價之法則有四種:經驗法則、比較法則、淨現值法則以及實質選擇權法則。然而,經驗法則並沒有考量到不同產業或技術的差異性,而僅利用一統一概念進行鑑價,無法提供適當的鑑價標準。比較法則所需之技術移轉或專利授權資訊大多屬於機密資料,無法隨處可得,而且於進行數量化的依據與標準如何確定亦是一大問題。淨現值法則過度仰賴「專家意見」,且忽略了真實商業世界中決策的易變性。是故,有學者認為實質選擇權理論是最適合用於專利技術鑑價。其中,選擇權模式中的B-S Model被廣泛地應用在專利技術鑑價。然而,當應用B-S Model於專利技術鑑價上時,其在再投入成本上會產生與真實商業世界不符的問題。 本論文採用了複合選擇權模式(Compound Option),利用有限差分法求其數值解,並撰寫程式實際評估。同時本論文利用現行商用之鑑價方法,實際操作鑑價案例,以相互比較B-S Model及複合選擇權模式於鑑價結果之差異。本論文發現傳統使用B-S Model之鑑價結果會高估了專利技術之價值,並且由敏感度分析中發現鑑價相關參數對鑑價結果之影響。

並列摘要


Option pricing theory, including the rule of thumb, the rule of comparison, the rule of NPV, the rule of real option…etc., is wisely applied in the patent/technology pricing. Wherein, in the rule of real option, the B-S Model is immensely applied in the patent/technology pricing. However, when applying the B-S Model in the patent/technology pricing, a problem, which the further cost does not conform to the activity of practical commerce world, is found. This paper proposes a compound option model for a possible solution. The finite difference method is devised to solve the compound option model. Several case studies are made, and the difference between the B-S Model and the compound option model is addressed in this paper. The pricing result of the B-S Model for the patent/technology pricing is highly evaluated in comparison with the compound option model. This paper also addresses the influence of the pricing results for the patent/technology pricing by each related parameter from the sensitivity analysis.
