The amish and mennonite ladies have used the symetrical pleating style for many years only no-one has thought to patent it. This style has been in the public domain for years well before utilkilts came along.

If you think about it, most kilts are pleated this way as Jeff has said it's just the location of the box pleat. Either you have it at the side or in the centre or any combination.
Just want to clear any question that Utilikilts were first to come up with this style of pleating, they weren't. They just hold an American patent.
