trademark
Is it legal to use the TM symbol?
<p>I am making a game, and I have a worries is it legal to use the Trademark Symbol in the logo of the game?</p>

<p>The ™  symbol, is similar to the (c) symbol. There are both used to assert trademarks and copyright respectively. ™ is for unregistered trademarks, while (r) is.</p>

<p>As Dale points out, it's illegal to assert or use a trademark that isn't yours, as it is false and misleading. Using a trademark that is not yours is known as <a href="https://en.wikipedia.org/wiki/Brand_piracy" rel="nofollow">brand piracy</a>.</p>
