According to Jiwei.com, a jury in the West Texas Court of the United States announced a verdict on December 5 that European chip manufacturer STMicroelectronics must pay Purdue University US$32.5 million in compensation for infringing a transistor technology patent.

The jury agreed with Purdue University that STMicroelectronics' use of silicon carbide metal-oxide semiconductor field-effect transistors (MOSFETs) in electric vehicle chargers and other products infringed Purdue's use in "high-voltage power applications." transistor patent rights.

A spokesman for STMicroelectronics said, "The company will appeal the verdict." Michael Shore, a lawyer at Purdue University, said the evidence against STMicroelectronics is "overwhelming" and that the company may have to wait until 2026 for the patent to be issued. More than US$100 million in patent fees were paid before the deadline.

It is reported that MOSFET is usually used in electronic products to control and amplify current. Purdue University sued STMicroelectronics in 2021, alleging that its MOSFETs used in solar HVAC systems, car charging stations and other renewable energy products infringed on two patents related to transistor technology.

Purdue's patents, covering semiconductor and MOSFET technology innovations for high-voltage power applications, were filed by former Purdue professor James Cooper and his then-student Asmita Saha.
