body: I recently stumbled upon a product patented in the 1950's--let's say it's a beard comb called the "Drongle"
  
  
  After the patent expired, another company trademarked "Drongle" in 2006 and began selling the beard combs.
  
  
  In 2013, the new manufacturer's "Drongle" trademark was cancelled--although they still manufacture and market their beard combs under the same name.
  
  
  Two questions:
  
  
  \*Is it permissable to manufacture beard combs and market them under the "Drongle" name?
  
  
  \*If so, should I file for a trademark on the name "Drongle?"
  
  
  
title: Can I use a cancelled trademark if the owner is still manufacturing the product?
