How could I possibly know if I can use the name 'LexCorp' for a real company. LexCorp is the company of Lex Luthor in the comic books of DC.

You can check the USPTO trademark database, to see if it is a registered trademark. You could also ask LexCorp about their claim that it is a registered trademark of DC comics or WB, though their CEO appears to be a criminal mastermind and might not tell the truth. There is some unclarity as to the latter point (criminality). USPTO includes a "don't rely on the database" disclaimer, so maybe it is registered and it just doesn't show up


LexiCorp was registered then abandoned. See details below. enter image description here https://huski.ai/trademark/78509802

The reason of giving up this trademark was not clear.

  • LexCorp, or LexiCorp?

    Given that LexCorp in real life has a Spanish language description for a law firm in the advertisement displayed, it seems likely that the person using it didn't know of its comic book connotations originally and eventually found those connotations to be a drag and found another name.
