Is it okay to mention a certain brand in an essay?

<p>Is it okay to mention a certain brand(food, clothing, etc) in an essay? I'm just using it as an example to compare something. Would that have copyright issues?</p>

<p>of course its fine, you can mention brands when talking to people, can’t you? right.</p>

<p>Even if you published it in a novel, there would be no copyright or trademark issues.</p>

<p>Thanks! :-* </p>
