I think Tomoko Fuse et al. has a patent on some of her origami bowls. Go to this page, scroll way to the bottom and follow links within: http://www.origami-resource-center.com/origami-kitchen.html I once saw a decoration, a bauble with an origame crane inside it, this was patented. But I don't know where the link is anymore. If you go to google search, there is an option under "more" which allows you to search for patents. Diana
