In March of this year, OpenAI filed a UDRP proceeding against the ChatGPT.com domain name at the World Intellectual Property Organization. OpenAI’s ChatGPT service has become one of the most popular artificial intelligence-driven chat platforms with well over 100 million users. The company uses chat.openai.com for its ChatGPT platform.
Prior to the filing of the UDRP, ChatGPT.com had been used by a website called ChatAI.com. You can have a look at how it was being used by visiting Archive.org. After the UDRP was filed, Whois privacy was lifted, and the Whois record showed the domain name was owned and used by a company in Puerto Rico called Site Matrix.
