Do you need to respond to a refusal to register your mark, including (but not limited to) a possible finding that your mark appears to be:
likely to cause confusion with another mark(s)
merely descriptive (or generic) or deceptively misdescriptive
primarily merely a surname
geographically descriptive or geographically deceptively misdescriptive
deceptive
functional
multiple marks instead of a single mark
a protected symbol (e.g., a flag, the Red Cross)
used in a manner that would not be perceived as actually being a trademark/servicemark*
