- Linton Crystal Technologies sued Zhejiang Jingsheng in the US District Court for the Eastern District of Texas (Marshall Division) on September 22, asserting two US patents (No. 11,255,024 and No. 11,814,746) covering seed-lifting systems in Czochralski crystal pullers, and seeking damages, treble damages for willful infringement, and a permanent injunction.
- Jingsheng reportedly won a roughly 3 billion yuan (~$420 million) Tesla order for crystal pullers earlier this year and disclosed the suit to Shenzhen investors on September 24, saying its products use "technical solutions entirely different" from the patents and that it expects no material business impact.
- Tesla is not a party to the lawsuit, but its $10.1 billion "Project Crystal Sun" solar factory in Fort Bend County — filed in August with production targeted for early 2029 — depends on the ingot-pulling equipment now at the center of the dispute; the first patent was granted in February 2022 and runs until 2040.
- Chinese trade-press reporting cited by Electrek lays out a timeline of Tesla's tender: closed in February, contracts signed in March, shipments starting in April, with full delivery planned for Q3 — and Linton, a direct puller competitor, did not win the order.
- Both suppliers are financially squeezed amid China's solar manufacturing glut: Jingsheng's revenue fell about 40% year-over-year in H1 2026, and parent Dalian Linton posted a small loss over the same period.
- Electrek's analysis notes that patent cases in the Marshall Division typically take years, making an injunction against equipment already shipping to Texas a long shot, with a settlement or licensing deal the likelier outcome.
Why it matters: Tesla's 100 GW US solar target — roughly 300 times its current Buffalo output — can only be hit by buying Chinese production lines, and the lawsuit exposes how that strategy inherits Beijing export approvals, supplier disputes, and financial fragility from China's overcapacity crisis. Even if the case settles, the fight illustrates that Tesla's "American-made solar" pitch rests on equipment and IP flows it doesn't fully control.
