Larry that same thought came up in my head but I thought, NO that isn't enough to materially change the appearance of the wheel???? But you never know. A patent attorney could probably tell you.
Take a look at the picture below very closely...what do you see changed? Both wheels are made by Coddington...the wheel on the left is what I ordered...when I got the "FIRST" set, they were made with the center on the right(rotated pentagon), I refused delivery because that's not the Campy correct design....they made a complete new set.
The centers on the right is one way to change the design enough to say its different. That is the design that some other vendors get.
