There is a growing awareness that the success of many firms does not only rely on the tangible assets, but also on technological innovation which has grown increasingly important for firms in every industry. Firms must develop and increase their market values by focusing on the use of the patent indicators to advance their patent portfolios in the market. The objective of this research is to examine the influence of (1) Patent Counts, (2) No. of Assignee, (3) No. of Assignee Country, (4) No. of Inventor, (5) No. of Patent Reference, (6) No. of Patent Citation Received, (7) No. of Claim, (8) No. of IPC, (9) No. of UPC, (10) No. of Non-Patent Reference, (11) No. of Foreign Reference upon the firms' market value of the top market value firms. The market value data of this research are obtained from the COMPUSTAT database. In addition, the patent data are downloaded from the United States Patent and Trademark Office (USPTO). The panel data created in this research contains patient data and market value spanning the period from 2001 to 2010. A panel data model is used to examine the relationship between patent value and market value. Furthermore, this research finds out that 'No. of Patent Reference', 'No. of Claim', 'No. of Non-Patent Reference' and 'No. Of Foreign Reference', are significantly positively correlated with firms' market value.

在知識經濟時代中,企業的核心競爭價值已由過去以勞力、廠房及資本等有形資產為基礎,轉變至技術創新為核心。企業藉由專利指標的運用促進專利佈局並發展及增加市場價值。本研究目的為利用專利指標評估專利價值與企業市場價值之間的相關性,其中,專利指標包括: (1) 專利數量, (2) 所有權人數量, (3)所有權人所屬國家數量, (4) 發明者數量, (5) 專利引證數量, (6) 專利被引證數量 (7) 專利範疇數量 (8) IPC 數量 (9) UPC 數量 (10) 非專利引證數量 (11)國外專利引證數量。其中,市場價值數據來自 COMPUSTAT 專利資料庫、專利數據來自美國專利商標局資料庫 (USPTO)。本研究的市場價值和專利數據的縱橫資料為 2001 年至 2010 年 並利用縱橫資料模型來實證市場價值與專利價值的相關性。,研究發現,1) 專利價值與市場價值相關性具有產業相依特性、2) 專利引證數量、專利範疇數量、非專利引證數量和國外專利引證數量四者專利指標與市場價值有顯著相關、3) 訴訟後的專利引證數量、專利範疇數量和國外專利引證數量與市場價值高度相關。
