Without spending a whole lot of time thrashing through the past and how the things look, Google WebOS and Google gears both appear to match the descriptions of the VCSY patents. The Google WebOS (GoOS) seems to fit the way patent 6826744 would work. Google Gears appears to fit the way patent 7076521 works. Without being able to dig into both Google products, it would be very difficult to say for sure, but, the form is similar to the patent structures and the activity is the way the patents would typically be used in their most basic forms.
Both GoOS and Gears have been shoved to the background by Google since early last year and have been eclipsed by Google choosing to adopt Adobe AIR instead of pushing ahead with Gears.
Gadget Ads appears to be similar to the way Silverlight would work since both are fit to be associated with graphic and video content with on-board (integral) automation for making the “ad” interactive. Silverlight is Microsoft’s effort to abandon activeX controls on the web.
