在這近幾年間,積層製造的技術發展快速,透過專利的申請使得該技術獲得法律上的保障,也可對向行使權利來進行訴訟,而目前美國於積層製造產業的產業領導公司為Stratasys與3D Systems,其中Stratasys的熔融擠製技術相對於其他積層製造技術,具有技術門檻較低、使用機台與材料的價格較低的特點,對於想要進入該產業領域的公司而言,相對為最佳的選擇,因此市場規模發展快速。本文將對Stratasys的專利技術做深入的分析與探討。
本研究整理美國熔融擠製技術(FDM)的專利,做一巨觀分析,分析其專利概況,再特別聚焦於該技術的領導公司Stratasys,並做其微觀分析,從以下幾個面向進行探討:(1) 運用專利技術功效矩陣來分析Stratasys佈局策略;(2)藉由專利技術與申請年份矩陣來找出由本體圖所分類出的技術源頭與專利申請趨勢;(3)藉由專利原創性、普遍性、Citation lags、平均被引用數等指標,來評估與比較關鍵專利與各技術源頭專利表現;(4)檢視Stratasys專利訴訟策略,探討Stratasys訴訟專利是否運用於訴訟中,同時參考積層製造產業的其它專利訴訟案件,了解目前該產業的專利訴訟概況;(5) 從Stratasys公開專利的功效矩陣,分析其近年來的技術佈局重點,並預測未來技術發展走向;(6)總結Stratasys的專利佈局與公司的發展策略,提供積層製造相關產業的參考與發展建議。
In recent years, the development of Additive Manufacturing (AM) has attracted considerable attention and achieved substaintial commercial success. Patents endow the owners of developed technology with a set of exclusive rights, as well as an offensive litigation tool. Currently Stratasys and 3D Systems are two leading companies in this industry. The Fused Deoposition Modelling (FDM) developed by Stratasys has various advantages compared to other AM technologies, such as lower technologicial complexity, cheaper and multiple materials, affordable prices. All these factors contribute to the rapid growth of this type of sysyems, especially for the new start-ups. As a result, it will be of great interest to investigate the patent portfolio of Stratesys and analyze its technological features through patent mapping.
This thesis focused on the US patents of FDM technology and Stratasys. So the research unfolded as follows. (1) Technology-fuction matrix was applied to analyze the patent portfolio of Stratasys. (2) Based on the ontological structure, source patents and key patents for each type of technologies were identified by the analysis. (3) Key patents and source patents were evaluated by different patent indicators, e.g. originality, generality, citation lags, and number of citations. (4) Referring the the litigation cases in 3D industries, the IPR strategies of Stratasys have been extensively reviewed. (5) The possible developing trends of this technology were also proposed by analyzing the patent applications. (6) Finally, the patent analysis and development strategy of Stratasys were summarized.
