So does a design patent only apply to a specific design. IE. jointed lexan billed hard plastic rodent with rubber tail and profile of rago's rat? If not, I am pretty sure the heddon meadow mouse has been around for many years before rago's stuff.Don't see why a quality bait maker such as Rago needs to patent his stuff when no one else can do what he does anyway. Not to mention that there are like 12 different rat baits out there now.
