I am wondering what is novel in US Patent 7938262 for a potpourri holder:
I offer a variety of early American string holders, used in stores to hold a ball of twine or string for ease of packaging. Some were designed to sit on a counter while others hung. Some were hinged, some not. Some cast iron, some wire, but many materials were used. Hundreds of designs were made. It appears that this patent is solely to prevent anyone from selling an antique string/twine holder to hold potpourri?
My wife bought one of these and it's exactly the same as an old string holder that was in my grandfather's shop 70 years ago, except the materials are cheaper, it's made of wire instead of cast iron, but that doesn't appear to justify a patent. I was amazed to see a patent number on it when it doesn't appear to have anything new to it. It looks almost exactly like, and functions exactly the same, as the first image below.
