Would the real XChat be able to sue X-Twitter for name infringement?
Man, I remember being an IRC regular during the transition from XChat to HexChat. Now I learn HexChat is also dead :( [0]
Maybe? XChat would have to show an established market in commerce in each market that x is infringing that they have an established commercial precense in. Also it's harder if xchat doesn't have a trademark in each of those regions.
No, they would have to show an established market in commerce in ONE market that X is infringing.
