I am not sure what these patents add to the ones already out there.

I dont know what is new with these patents, but the fact that they keep on filing them shows they are working on improvements.

I took a look at the first one, and I'm with you on that one Lawrence. I've seen so many patents they are all blurred at this point. Anybody know what significance these have?

I believe these are patents that were originally posted as "patent applications" that have now been granted after review.
