So I have a software application that I’ve been selling via shareware for a few years, but the current name is not trademark-able (already in use by other applications). I want to change the name and trademark the new name. Assuming that I have found a name that the US PTO website indicates is not currently trademarked, I then have two options: 1) I can apply for the trademark under “intent to use”, wait to see if I am granted it, and then change the name of my application; or 2) Change the name of the application, then apply for the trademark under “current use”.
What I’ve read on the PTO website seems to indicate that number 2 is the more common and more preferred method. Other than the obvious risk of changing the name and then not getting the trademark, are there any reasons not to go ahead with number 2? Any advantages to number 1, in this kind of a situation?
