According to the United States Patent Office, nobody had ever thought of making a stick that a dog could fetch before March of 2002.
Why do you care?
Well, if you ever start a business that makes such chew-toys for pets, and Ross Eugen Long III decide to sue you... you're boned.
This should start to clarify the idiocy of the United States Patent System... and the effect it has on shutting down small businesses. What small business that might want to start making animal toys could afford to battle Eugene Long in court, when defending a Patent Infringement lawsuit runs about $3,000,000?
