Munich Regional Court finds Innoscience GaN chips infringe further Infineon patent - JUVE Patent

The Munich Regional Court recently ruled that Innoscience, a Chinese chip manufacturer, and its European distributor MEV Elektronik Service have infringed a German patent held by Infineon. This marks ... Read original →

The Munich ruling exposes Innoscience’s structural reliance on Infineon’s patented GaN die architecture, triggering a supply chain reassessment among downstream power module makers—especially in automotive and industrial applications. Operationally, Chinese GaN suppliers lacking robust IP portfolios will face escalating legal exposure and compliance costs in Western markets. Strategically, Infineon’s acquisition of GaN Systems has enabled a litigation-driven moat: its 450-patent family acts as both shield and sword, constraining non-Western competitors’ global reach. Rivals like Navitas and Transphorm may deepen partnerships with European OEMs to avoid collateral risk. Over the next 12–24 months, the GaN power semiconductor battleground will shift from wafer capacity to intellectual property dominance, potentially confining under-licensed Chinese firms to domestic and select emerging markets.
