body: I've encountered a trademark in the USPTO database which is listed as:
  
  
  
  > 
  > CONTINUED USE NOT FILED WITHIN GRACE PERIOD, UN-REVIVABLE
  > 
  > 
  > 
  
  
  What does this mean and what rights might the trademark registrant still have over the mark?
  
  
  * Does the registrant still have common law rights over the mark? If so, are they affected by this status?
  * Does this mean the registrant can never register this mark again?
  * Can another entity register this mark for the same purpose?
  
  
  
title: Trademark "un-revivable"?
