An anonymous reader shares a report: Nikola Tesla invented alternating electrical current. Nikola Motors is a mobility company working on a hydrogen-powered semi truck. Tesla makes fully electric vehicles and last December unveiled its EV Semi. Nikola Motors is suing Tesla Motors over patent infringements, according to Electrek. Nikola alleges that Tesla infringes on three of its patents: fuselage design, a wraparound windshield on a semi truck and a mid-entry door. Nikola claims that these design similarities have "caused confusion" among customers and stolen away over $2 billion in business, and that if problems arise with Tesla's Semi (like battery fires or glitches with autonomous driving), they'll be attributed to Nikola. Typical patent troll stuff.
