Re: [ATM] Too Small Optics-( and flex produced optics)

Bill,

In this thread, you said:
>Alan, who controls the patents ...

Mike dug around for us and turned up ONE patent (not plural). It deals specifically with a puller in the middle. Yet to do what was discussed in the thread would require a pusher in the middle, puller on the perimeter. Your patent claim does not address this, apparently, as your perimeter seems limited to compression.

Also, as Bob pointed out, you can't patent the idea of flexing before or after polishing. You can only patent the specific device with which you do the flexing. 

So, are there more patents?

Or, just the one?

John
