| Interesting. I looked it up and found the patent, US# 7,125,382.

I liked reading their reason for the rise in diabetes -- "sedimentary lifestyle, particularly in children...." They obviously are just reading what the media has to say, and don't seem like a medical device company. The fact their stock went up shows that untrained investors are thinking that a patent number gives rise to a company, but it never works that way.
In fact, if somebody else happens to overlap in any of the technology that they "claim" (which is probably a vaporware product, seeing that it's never been tested, it must be!), we will see them sueing for money quicker than ever.
The "images" of the 25-document page were not showing up for me, so I couldn't see what their numbers referred, but for some reason, it just seems like a vaporware product, sort of like that other company that claimed to offer a non-invasive meter using electromagnetic waves to measure glucose (Paragon??). *sigh*  |
