Ok, I want to use a name, but I'll use this pseudonym for this question (YYY ZZZ). I want to register this as a COMPANY NAME and WEBSITE that I will be making soon. I searched it on USPTO.gov and got this:
Goods and Services (ABANDONED)
Mark Drawing Code (4) STANDARD CHARACTER MARK
Filing Date April 22, 2008
Type of Mark TRADEMARK
Register PRINCIPAL
Live/Dead Indicator DEAD
Abandonment Date September 26, 2009
Since it is inactive, can I proceed to use it?
