According to Tom's Hardware, Elon Musk's Terafab semiconductor project has hit a legal obstacle before producing its first chip. A small U.S. company called Tera-print has sent a cease-and-desist order and filed a trademark lawsuit over the use of the name Tera-Fab.
Tera-print says it has sold Tera-Fab-branded tabletop lithography tools for more than a decade. The source reports that this existing commercial use of the name is central to the dispute, as the company moves to block Musk's project from using a similar trademark in the semiconductor space.
Since only one source was available, there are no differing accounts to compare. The reported facts come entirely from Tom's Hardware's coverage of the trademark conflict.
