The U.S. Patent Office has approved some truly bizarre ideas over the years. Patents for things like an umbrella for dogs, a banana-shaped suitcase, or a motorized ice cream cone have all been filed. These quirky inventions make readers laugh and share the content with friends. At the same time, patents are a serious legal matter, so combining humor with real-world examples makes for an engaging and credible entry. This subject is interesting, evergreen, and not too crowded in terms of competition.
