YMTC wins Munich injunctions against Micron over two 3D NAND utility models

A Munich court found Micron infringed two German utility models held by YMTC covering 3D memory staircase structures and barrier layers for word line contacts, ordering a halt to sales of the products in Germany. Micron said it disagrees, has appealed and is challenging the rights' validity; enforcement depends on whether the appeals court stays the injunctions.

• Munich court barred Micron from selling infringing products in Germany
• The rights cover 3D memory staircase structures and word line contact barrier layers
• Micron has appealed and is challenging the validity of the rights
• Three other YMTC Munich cases were adjourned to 2027
