Beijing IP Court denies Innoscience’s appeal against EPC’s compensated-gate patent
What happened
The Beijing IP Court denied Innoscience's appeal, upholding the validity of EPC's Chinese patent for a compensated-gate GaN transistor fabrication method. This ruling strengthens EPC's intellectual property position in the Chinese market for GaN-on-Si power devices. Neutral: This legal affirmation does not immediately alter supply, demand, or pricing for GaN components, but may marginally benefit EPC's competitive standing long-term.
