Tesla Patents
An overview of key patents that have shaped Tesla's technological advantage in electric vehicles, battery technology, autonomous driving, and manufacturing.
Tesla's Patent Strategy
In 2014, Elon Musk announced that Tesla would not initiate patent lawsuits against anyone who "in good faith, wants to use our technology." This "open source" philosophy aimed to accelerate sustainable transport adoption while Tesla continues to innovate and file patents for cutting-edge technology.
Despite this "open source" stance, Tesla maintains a substantial patent portfolio that provides insight into the company's technological direction and priorities. This page highlights some of Tesla's most significant patents across various categories.
