Can I use the name of a fictional company
<p>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.</p>

<p>You can check the <a href="http://tmsearch.uspto.gov/bin/gate.exe?f=searchss&amp;state=4810:5rami.1.1" rel="nofollow noreferrer">USPTO trademark database</a>, to see if it is a registered trademark. You could also ask <a href="https://www.lexcorp.io/#/about" rel="nofollow noreferrer">LexCorp</a> 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</p>

<p>LexiCorp was registered then abandoned. See details below.

<p>The reason of giving up this trademark was not clear.</p>
