gradalis playing hardball or business as usual

In its latest patent application, 20120183955, Gradalis makes no reference to BLT or any of the Graham or Waterhouse patents. Is this a sign of where things are at with them or just them sticking to the template they have used previously?

HC won't let me post the web address so here is the portal address where you can search for Gradalis.
