In an ongoing high-stakes lawsuit, Tesla has now asked a judge for emergency permission to serve subpoenas on numerous tech firms, including Facebook and Dropbox. Tesla believes these companies hold data connected to a recently-fired technician that the auto company says stole its trade secrets.

US Magistrate Judge Valerie P. Cooke in Nevada had already granted Tesla permission on Monday to serve Microsoft, Google, and Apple with similar subpoenas in the case filed against Martin Tripp, whom CEO Elon Musk has suggested is a saboteur.

Tripp previously worked at the Gigafactory in Sparks, Nevada, which manufactures Tesla’s batteries. The former employee insists that he is a whistleblower. He has previously told Ars that he witnessed large quantities of waste and that “punctured” cells as part of batteries were allowed to ship.
