St Patrick's Day Charms

For every holiday, there are inventions, trademarks, and copyrights created to serve those celebrating the holiday. St Patrick's Day is no exception, for example the term leprechaun has been used in hundreds of different trademarks. Every green hat, streamer, flag, and other party favors used by merry-makers during the parade was created by an inventive mind. Take a look at few shamrock shaped design patents.
