6. Some Minnesota candy company trademarked “Chicago Mix”
Of the Gopher State's transgressions over the past few decades (starting Tarvaris Jackson, etc.), this one is by far the most boo-able. Back in 1992, a small St. Paul-based chain called Candyland patented the trademark for "Chicago Mix" and even sued Garrett this year for using the name of the product they created. While the official name of the caramel/cheddar blend is now "Garrett Mix", if "Sears" and "Comiskey" are examples, old names die hard with locals.
