Puzzle Patents

Many of the puzzles listed on this site are patented. On the page of any particular patented puzzle it usually mentions the inventor and the patent publication date and number, and has a link to a pdf file of the patent itself. On this page I have collected all those links together.

All the patents listed here are of actual puzzles, or are patents of historic interest that are mentioned in the Cubic Circular or the Circle Puzzler's Manual. Many patents exist that have never been made into real puzzles, or that are minor variations of existing ones. For a nice collection of such patents, you should visit Joshua Bell's Puzzle Patents page.
