You're wrong, I know for a fact that you can (and should) register your product (including the name) in Europe. I guess what you're saying only applies to US but the author is European, hence my advice.

When you register you specify your work, the name and the sector it belongs to (films, novel, web sites, etc.) and you get a document that testifies your rights over it. I know this because I used my filing to have Google remove a clone of my app from the store. It was a lengthy process, but with the registration you can have leverage.

"In general, registration can serve as prima facie evidence in a court of law with reference to disputes relating to copyright."
