I've discovered the name I gave to my software is already used . It's not a registered trademark and the two products although both software can't be confused. Can I ignore this or do you think I need to change the name?
the trademark can be applied at anytime and their prior use invoked and then you'll need to change the name. It's best to change it before you build up a significant userbase or awareness.
The name is reftrack, something to do with employee scheduling. It wasn't coming up on Google a few months ago when I chose the name grrr.
