A federal patent lawsuit filed in East Texas indicates that massive quantities of Chinese crystal-pulling equipment are bound for Texas to build out a 10 GW solar production line.

Court filings and public records tie the multi-hundred-million-dollar machinery deal to Tesla’s planned $10.1 billion vertically integrated solar gigafactory in Fort Bend County, highlighting the U.S. solar industry’s continued reliance on imported heavy machinery to establish domestic ingot and wafer manufacturing.

Linton Crystal Technologies, an equipment maker based in Rochester, New York, filed a patent infringement complaint in the U.S. District Court for the Eastern District of Texas against Chinese machinery manufacturer Zhejiang Jingsheng Mechanical and Electrical, known as JSG.

The legal dispute centers on high-precision industrial furnaces called Czochralski crystal pullers. The machines melt raw silicon and grow monocrystalline silicon ingots, which are subsequently sliced into thin wafers to make solar cells. Ingot pulling represents the foundational first step in the entire solar manufacturing chain.

Linton alleges that JSG infringed on its patented designs for specialized seed-lifting and rotating systems used inside high-temperature crystal pullers. The systems carefully regulate the growing silicon crystal as it is drawn out of the molten material to ensure uniform structure and diameter.

According to the court complaint, Linton and JSG competed directly to supply crystal-growth furnaces for a major photovoltaic project in the United States.

Linton claims JSG secured the supply contract by utilizing contested designs and subsequently began importing the hardware into the country.

To establish personal jurisdiction in Texas, Linton cites public market reports showing that JSG secured a massive contract to supply crystal pullers and associated equipment for a 10 GW photovoltaic production line in Texas, with deliveries scheduled in 2026.
