I know in order to maintain your Trademark, that you have to use it in interstate commerce. The question is, how often do you have to use it? i.e. once a month, once a year, so many times within a year?
I've got a trademark for a clothing line I'm starting. But still need to send it across state lines for it to be considered in use. It is unregistered, so I'm just using the TM. But I'm still working out some details, so I was needing to know how often I have to use it so my trademark is still considered in use?
