The buyer of the domain appears to be the German Computer store, notebooksbilliger.de
The domain name NBB.com is just being forwarding to the .de site.
The site notebooksbilliger.de gets plenty of traffic already, has a PR of 5, an Alexa rank of 4,318 worldwide
Since buying the domain name last year, Notebooksbilliger.de AG , applied for a US trademark on the term NBB on March 22, 2011 for the class:
“Data processing equipment and computers, in particular desktop computers and laptop computers”
This is a good example of how to properly use domains and trademark law to protect your IP.
Congrats to the buyers on a domain that now looks like a cheap acquisition.
