Disclaimer: There is no evidence of a pending or approved trademark for "Grok 5" in the USPTO database as of now. xAI’s pending "Grok" trademarks may cover "Grok 5" as a version of their AI product, but no specific filing for "Grok 5" exists. The presence of other "Grok" or similar marks (e.g., "Groq") suggests potential challenges if xAI seeks to register "Grok 5" separately.The term "Grok" has faced multiple trademark challenges, which could complicate any future filings for "Grok 5." For example:

  - **Groq Inc.**: An AI chip company, Groq, holds a federal trademark for "Groq" (filed in 2016) and has issued a cease-and-desist letter to xAI, alleging potential confusion due to the phonetic similarity between "Groq" and "Grok."

 

  - **Bizly**: Another startup, Bizly, claims to have applied for a "Grok" trademark in 2021 for an AI-powered app, asserting prior use.

  Additional companies, such as AVIK Partners, LLC (trademark registered in 2012 for online software) and Advanced Micro Devices, Inc. (filed in 2016, later abandoned), have also filed for "Grok" trademarks in various tech-related categories.
