As I walked down the aisle in the supermarket shopping for a particular brand of hot sauce, I realized the price differences among the more popular varieties. When I looked at the more expensive hot sauce brands I noticed something peculiar: the premium hot sauces have more distinctively shaped bottles. So I developed an intellectual property hypothesis right on the spot! (o.k. I need to get some hobbies…)
My Hypothesis: The more expensive and distinctive hot sauce bottles will have 3-D shape trademarks to secure their unique look and feel.
I later verified this (at http://www.uspto.gov) and found that the two more expensive brands with unique design features indeed have registered trademarks. The first one is the Cholula brand with a trademark on its distinctive wooden top. The other is the Tabasco brand with a trademark on its unique red cap and green label on the neck. The other brands listed below have no such packaging trademarks.
