Greg,
These charts with their captions would be a nice addition to someplace in our growing patent information sites.  Maybe on the new PDF page?  Thanks Ray for posting them.

Ray,
we need to get you to join WAGS.  We have a pretty extensive list of cookware patents that we have started already.  Thanks for the link.
