There is some prior art in the field. US 3429265 A from 1960 for example.
Also CA 2367192 A1 from 2002 by inventors Anthony J. Cesaroni, Michael J.
Dennett, Jeroen Louwers
There seems to be a distinct lack of reference to Prior Art in modern patents.
Have they dropped that criteria so I can patent the wheel now?
Cheers,
