Yes, there are two issues there. Issue number one, is XYZ actually confusing with XYZA? There are many factors that the professional looks at in determining that. The other is the nuances, as Ms. Fuhrer was suggesting, of doing actual searching. I've been practising for over 30 years and I don't do trademark searching. I have a professional trademark searcher who does all of my searches for me because I would not hazard a guess at how that could be done comprehensively by someone just walking up to a computer and searching. So I actually have a searcher who lives here in the Ottawa area, who does all of my trademark searching.
