Navitas Files Second Patent Suit Against Renesas

The latest case was filed in a Texas district court and targets the Japanese semiconductor firm. The claims concern gallium nitride, or GaN, technology, which can replace traditional silicon in semiconductors used to power electronics and other devices.

Navitas filed a separate suit against Renesas in August, alleging that the company’s GaN product lines infringe Navitas patents. Renesas announced a new GaN product in late September and unveiled a family of GaN power transistors in October. Both lawsuits remain pending.
