Is "Neovim" trademarked?

This may be a random question but I couldn’t find the answer to it. I was following the Rust’s trademark… controversy, and was wondering about the usage of the name “Neovim”. I see a lot of project names like “goneovim” that references Neovim, but not sure if there’s any trademark restrictions on using the name on say new Neovim forks or other projects. Sorry if this stirs up a can of worms (since the Rust issue was quite controversial) as it’s perhaps more a curiosity.
