They have been pushing for a lawyers opinion on this, so here is one. http://www.avvo.com/legal-answers/what-does-it-mean-to-disclaim-a-word-in-a-trademar-359289.html
" A disclaimer means no rights are claimed to the word disclaimed except in the way the applicant uses it." (emphasis added)
If they continue to police this they will end up in court. The have won their trademarks but they have LOST the term. And they need to just focus on making their bears and leave everyone else alone.
