Thats not how IP works. Unless Atsuko Sato is going to get behind a legal challenge against 3 other Neiro tokens. You would literally have to take all 3 on. 

2 of solana own the ticker $NEIRO on a few exchanges. 

2 on eth do too. You’re gonna challenge them all with what “IP”? Ticker IP? 

Considering @neirowoof was the first to use the ticker and the first to file trademark in the USA. That will be interesting.
