YMTC Wins Injunction in Germany as Micron Loses NAND Patent Case
nashnova research
A Munich court ruled Micron infringed two YMTC NAND flash patents and issued two injunctions — Micron's European NAND shipments now face direct legal risk, with the next focus on a possible appeal and actual sales impact.
What did the court actually rule?
Munich's Regional Court I found that Micron Technology infringed two NAND flash patents held by YMTC (长江存储) and granted two injunctions.
This means → Micron's affected products are now legally barred from sale and shipment in Germany.
The ruling is the latest front in the YMTC–Micron patent war, which has now expanded from the US and China into Europe.
Why does this case matter?
Germany is one of Europe's largest semiconductor markets; the injunctions directly threaten Micron's NAND business across the continent.
In plain terms = the patent fight used to be a US-China affair. Now a European court has sided with YMTC, turning Micron's two-front pressure into a three-front problem.
Micron is already under pressure on multiple fronts; the German injunctions escalate its legal exposure further.
What to watch next?
First, whether Micron appeals in Germany — and whether the injunctions are stayed pending appeal, which would directly affect shipment timing.
Second, whether the injunctions bite in practice — i.e., whether they actually block Micron NAND products from reaching European buyers.
This signals that Chinese memory makers' patent capabilities are going global, potentially reshaping competitive dynamics in the worldwide NAND market.
