Can someone explain what these number means in trademark description?
<p>I was doing some trademark search in <a href="http://tess2.uspto.gov" rel="nofollow">TESS</a>. I sew the following description.</p>

<blockquote>
  <p>Goods and Services:   IC 038. US 100 101 104. G &amp; S: Communications
  services -- namely, transferring of electronic messages for groups of
  two or more people by means of a global computer network. FIRST USE:
  19980120. FIRST USE IN COMMERCE: 19980120</p>
</blockquote>

<p>While I do understand <code>IC 038</code> means international class code, I couldn't figure out what these numbers means <code>US 100 101 104.</code> </p>

<p>I believe its more like subclasses. But i'm not sure.</p>

<p>Can someone tell me where I can get that details in USPTO?</p>

<p>These are for US trademark classes. You can safely ignore them. The international classes are what count.</p>

<p>I think they are US classification at USPTO. Please refer to:</p>
