In an invalidation trial with respect to the Basic Patent on Electrodeposited Copper Foil for Lithium Ion Batteries held by Furukawa Electric Co., Ltd. (Furukawa Electric, hereafter), the Japan Patent Office has delivered a decision up遊雅堂 おすすめゲームlding Furukawa Electric's patent.
Background and 遊雅堂 おすすめゲームtails
Lithium ion secondary batteries are widely used in consumer fields such as mobile p遊雅堂 おすすめゲームnes and notebook PCs, and with the widespread adoption of electric vehicles, demand is forecast to grow even further in the future. Furukawa Electric developed an electrodeposited copper foil capable of improving battery performance for the anode material of lithium ion batteries, and was awarded a patent for the technology in 2005. Furukawa Electric's NC-WS electrodeposited copper foil for lithium ion batteries enjoys a world-leading share of roughly 40% of the global market.
The lithium ion secondary bat遊雅堂 おすすめゲームries currently manufactured and sold in Japan mainly use electrodeposi遊雅堂 おすすめゲームd copper foil, and use of this basic pa遊雅堂 おすすめゲームnt is considered mandatory.
While the validity of t遊雅堂 おすすめゲームse rights were challenged in 2010 when the Japan Patent Office was asked to conduct an invalidation trial for the patent, this past February 17, the Office delivered the decision that the patent s遊雅堂 おすすめゲームuld be upheld (decision of validity).
For its part, Furukawa Electric will continue to expand sales to bet遊雅堂 おすすめゲームr meet the demands of customers, and at the same time seek to crea遊雅堂 おすすめゲーム and utilize useful in遊雅堂 おすすめゲームllectual property rights.
