電動車用之新興鋰電池市場 / Depletion of oil, Increasing of oil price and rising of regulation for the environmental protection are leading the demand for the electric vehicles which are much more eco-friendly automobiles. Li-ion battery is most commonly used rechargeable battery for various mobile application devices and also can be used for the electric vehicles. The Li-ion battery market for EV will grow rapidly in near future. To succeed in the emerging Li-ion battery market for EVs below 4 conditions should be satisfied in advance. First, technology innovation should be achieved. The achievements of safety, high power and long life span are most important. Second, cost reduction and long-term sourcing plan for Lithium are necessary. Now the Li-ion battery is still much expensive compare to NiMH battery of which is used for current HEV Toyota Prius. The application of low cost raw materials and economies of scale can reduce cost a lot. The pre-emptive preparation for Lithium resources are necessary because the amounts of natural Lithium are limited and the price can be fluctuated. Third, strategic alliance to win this emerging LIB market of EV is mandatory. The joint venture and alliances among automobile companies and Li-ion battery companies can help each other because stable supplies of LIB and securing of large customers can be attained at the same time. Last, developing the new business related to the EV should be progressed in parallel. Launching of battery exchange station and charging station will affect to positively for expansion of Li-ion battery marker for EV market.

現代人類的文明生活中，不論使用何種能源，絕大部分皆會轉換成電能被使用。基本上，文明社會為一「電」的社會。有鑒於電能儲存裝置對於生活的必要性，本文選定其為發明專利侵權問題之研究標的。 本文首先分析美國之發明專利制度與發明專利侵權成立要件，了解美國法院對於上述要件之看法。其次，針對電能儲存裝置之產業狀況與發明專利申請、布局和侵權訴訟等進行分析，了解此產業中主要的訴訟議題。並配合實際之美國的電能儲存裝置發明專利訴訟案例，了解產業實際的發明專利訴訟問題。且配合台灣廠商之研發與製造情況，針對台灣相關產業在此領域所遇到或可能遇到的訟訴困境提出因應之道。 本文認為台灣電能儲存裝置廠商因整場輸入技術與設備的經營模式，擁有較少的自有技術。對於下ㄧ代之薄膜太陽電池與燃料電池的開發，如能妥善規劃資源投入，並建立關鍵技術，則台灣上述廠商有機會掌握到下ㄧ波產業的先機。 本文經由比較太陽電池與燃料電池的專利申請狀況，發現台灣太陽電池的廠商在專利布局上有所不足，其相對於燃料電池，在美國的專利申請數量較少，且近年來於美國之專利申請數量銳減。發明專利能保護技術研發的心血，完善的專利布局更可讓發明人之技術受到完整的保護，此應為以後台灣廠商進行智慧財產權管理與規劃時，所應深慮的事項。
