Never-the-less the patent office saw fit to issue a patent on it. This
is despite the requirement that a patent be "not obvious to a practitioner
in the field".
It is ironic that one of the grievances that the founding father's had with the
crown was the arbitrary awarding of patents.
Although I know this patent exists, I don't know the date it was awarded on.
Can anyone supply that information? Also, when was it applied for? These can
be very far apart in the US, unlike overseas where the filing of a patent
application is public knowledge and the public can comment (which means, of
course, that the award has to be timely to be effective)
