Hello there,
I just wondered if it may be a problem in case I pick a "similar" name but not in fashion of "Call of Duuty". More like similar to name of series, something like for example "SimPlanet" which may remind Sim Series from Maxis. Can I use it if they have no trademark?
Considering even Google had problems with GMail, ( http://en.wikipedia.org/wiki/Gmail#Trademark_disputes )
Is it "even" wiser than usual to trademark anyway to avoid any problem. In case of having trademark, does it have to be US one to avoid Maxis?
Also does applying first at any country give you any advantage? Or just have to apply asap in all countries to protect it? (I read some about Madrid Protocol but still not sure)
