Well, it looks like the $450 million patent dispute settlement didn’t actually settle things between Research in Motion and NTP, the Virginia based holding firm that owns several patents on “Push” mobile email technology.  The two companies had been entrenched for years in a heated patent infringement battle which was settled in March of this year to the tune of $450 million.  It seems like now the two companies can’t agree upon what they agreed upon earlier. 

RIM, which helped popularise mobile e-mailing with its thumb-operated BlackBerry, said on Thursday it has asked a U.S. court to enforce the terms of the deal the two firms announced in March because NTP “refuses to honour all of its obligations.”
