• Tari Labs sued Lightning Labs for trademark infringement over the use of the name "Taro" for its protocol that allows users to issue assets on the Bitcoin blockchain.
• Judge William H. Orrick issued a temporary injunction forcing Lightning Labs to halt further development of Taro until the project has been sufficiently rebranded.
• Tari argued that it and Lightning compete in the same digital blockchain ecosystem, provide similar goods and services, and market to similar developers and users.
• The lawsuit has drawn criticism from members of the open source community who insist that trademark enforcement has no place in free and open source software.
• Tari Labs launched Tari, a blockchain protocol that focuses on digital assets, in April 2020 and subsequently registered the name as a company trademark.
• Lightning Labs announced Taro two years after Tari's debut, and a test version of the software was released last September.
• The injunction means Lightning's development of Taro has been halted and Lightning Labs will have to rebrand or appeal the decision before moving forward.
