Elon Musk's chipmaking venture Terafab has a naming problem, and it's not a good one.
A small U.S. company called Tera-print sent Tesla and SpaceX a cease-and-desist letter in May, arguing the Terafab name is too close to its own Tera-Fab, a beam pen lithography tool it has sold for about a decade to bioengineering and microfluidics customers, reportedly including the U.S. Department of Defense. Tesla and SpaceX, joined by SpaceX AI, counter that the two businesses aren't remotely the same: Terafab is meant to mass-produce chips for AI, cars, and robots, while Tera-print's Tera-Fab is a tabletop tool for prototyping. On paper, though, both trademarks fall under the same semiconductor-technology classification, just with different technical descriptions. The two sides reportedly held settlement talks, and Tesla made an offer, but Tera-print says Tesla wanted to keep negotiating rather than resolve things - so now it's suing to defend its registered mark.
This is a reminder that grand chipmaking ambitions can get tripped up by mundane trademark law long before a single wafer ships. It also shows the risk of rushing to file broad trademark classifications without a clearance search, especially when a decade-old registration already sits in the same bucket.
For a company promising tera-scale chip output, getting outmaneuvered by a tabletop lithography tool maker is an inauspicious start.
