Vapor Group Inc (VPOR)

[Master-of-Disaster]

So unlike mCi*(r), VPOR (tm) is not a registered trademark then.

Yep I just had to stop by and give you guys grief.

TM v. (R)
The U.S. Patent and Trademark Office website has the best explanation for it:

"Any time you claim rights in a mark, you may use the "TM" (trademark) or "SM" (service mark) designation to alert the public to your claim, regardless of whether you have filed an application with the USPTO. However, you may use the federal registration symbol "®" only after the USPTO actually registers a mark, and not while an application is pending. Also, you may use the registration symbol with the mark only on or in connection with the goods and/or services listed in the federal trademark registration."

The R-in-a-circle means that the trademark is registered with the United States Patent & Trademark Office. That involves filing an application with a fee, and establishing that the owner is entitled to exclusive use of the mark in connection with particular goods and services. One may not use the R-in-a-circle sign without a registration.
