The US International Trade Commission upholds its ruling that Innoscience infringed Infineon's gallium nitride patent. An import ban on the Chinese firm's GaN chips into the United States now takes effect after the presidential review window closed. The decision protects Infineon's position in power electronics and fast-charging markets.

A final US International Trade Commission determination targeting Innoscience has been upheld once the presidential review window closed, confirming that the Chinese gallium nitride chipmaker infringed a patent owned by Germany's Infineon Technologies.

The ITC ruling imposes an import ban. The decision bars Innoscience from importing its gallium nitride chips into the United States. This follows the conclusion of the presidential review window on the ITC's earlier findings.
