body: The fictional example below replicates my situation: 
  
  
  * A company already creates websites and owns a trademark with a pattern like XXX4 (e.g. "WEB4").
  * My company builds websites for children and I want to give it a name like xxxForyyy (e.g. "WebForKids")
  
  
  Cann I use "webforkids" for my company? 
  What do I risk if I do so?
  
  
  
title: trademark with digit - likelihood of confusion
