I was doing some trademark search in TESS. I sew the following description.

Goods and Services: IC 038. US 100 101 104. G & 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

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

I believe its more like subclasses. But i'm not sure.

Can someone tell me where I can get that details in USPTO?


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


I think they are US classification at USPTO. Please refer to:
