Some SR's have not been updated since being assigned

I have 3 SR's from 2 & 3 weeks ago that have been assigned but have not had any fuirther updates and I was wondering if anything further was going to be done with them.  The SR's are as follows:

1-2206343229, 8/24/2011, Assigned but nothing added to SR

1-2206343222, 8/24/2011, Assigned but nothing added to SR

1-2196452699, 8/16/2011, Assigned but nothing added to SR
