Anthropic Bites The $10,000,000 Hand That Feeds It In New Logo Lawsuit Over An ‘A’
Artificial intelligence giant Anthropic sued a major paying customer for trademark infringement over a similar logo.


Artificial intelligence giant Anthropic sued a major paying customer for trademark infringement over a similar logo.
Anthropic demanded in a July 1 lawsuit that Abnormal remove the parallel slash from its logo, so consumers do not confuse it for Anthropic’s logo, Axios reported. All Abnormal employees use Anthropic’s Claude, and Evan Reiser, the AI security platform’s CEO, projected it will spend $10 million on Anthropic this year, according to an Abnormal blog post.
“This additional element in the Infringing Logo is not merely an insignificant alteration; it is the defining feature that creates confusing similarity with Anthropic’s Anthropic Marks, and its introduction fundamentally changes the commercial impression of the mark,” the lawsuit said.
Anthropic, Denise Howell, Anthropic’s outside legal counsel Morrison & Foerster, Reiser and Abnormal AI each did not immediately respond to the Daily Caller News Foundation’s requests for comment.
“Abnormal was built by inventing, not copying … he accusation that we copied another company to deceive customers is so personally offensive. It is the opposite of who we are,” Reiser said in the blog post.
“I have been a major Anthropic user and advocate. My personal Anthropic account will spend ~$1M this year (Abnormal will be >$10M),” Reiser added.
