長江存儲與美光自2023年11月起展開全球3D NAND專利戰,雙方在多國互控侵權。

中國記憶體大廠長江存儲(YMTC)與美國美光(Micron)的全球3D NAND專利戰出現重要進展。外媒報導,德國慕尼黑法院認定,美光侵害長江存儲2項德國實用新型,核發禁制令,要求停止在德國銷售涉案產品。

據報導,這是長江存儲自2023年11月與美光展開全球3D NAND專利戰以來,首次取得具有實質市場約束力的禁令勝利,目前另有3件德國案件尚未作出實體判決。對此,美光已上訴並稱將挑戰權利有效性;禁制令是否執行,待高等地區法院是否裁定暫停。

據專利訴訟媒體《ip fray》報導,慕尼黑第一地方法院第七民事庭9月18日針對長江存儲提出的2項德國權利作出有利判決,分別涉及「三維儲存裝置的階梯結構」以及「3D NAND字線接觸的阻障層」技術。法院據此向美光核發兩項禁令;另外3件在慕尼黑提出的訴訟則尚未作出實體裁判。

不過,這並不代表美光所有記憶體產品都遭到德國全面禁售。此次禁令針對的是被認定涉及相關權利的特定3D NAND產品,而且案件仍有後續司法程序。ip fray指出,除非慕尼黑高等地方法院在上訴程序中暫停執行,相關禁令可能很快進入執行階段。美光則表示不認同判決,將提出上訴,並繼續挑戰相關權利的有效性。

報導指出,這場爭端並不限於德國。美光向美國證券交易委員會提交的文件顯示,長江存儲已在美國、英國、德國以及歐洲統一專利法院等司法管轄區,對美光及其子公司提出多項專利侵權訴訟,其中慕尼黑就有5件案件涉及特定3D NAND產品。

雙方的專利戰可追溯至2023年11月,長江存儲當時在美國加州北區聯邦法院控告美光部分3D NAND產品侵犯8項美國專利,之後又進一步擴大訴訟範圍。美光則透過美國專利審判及上訴委員會等程序挑戰長江存儲專利有效性,使這場爭端逐漸從單一市場擴大成跨國專利攻防。

此次德國判決的重要性,在於長江存儲不再只是尋求損害賠償,而是取得可能直接限制競爭對手產品銷售的禁令工具。若禁令最終維持,將提高長江存儲在後續全球3D NAND專利談判與訴訟中的籌碼;但在美光上訴以及相關權利有效性爭議尚未落幕前,這場專利戰仍遠未結束。
