I think you can see that this is an
area where there is
lots of
prior art and
products in the market place. We now need to
narrow our
area of focus. Let's go back to
mackgadget's earlier post:
I am thinking of ideas for feeding, watering, bathing, grooming, litter boxes, pooper scoopers etc. Also ways to keep pets off furniture etc. as well as the doggie door.
Let's go with the
doggie door for a while but expand it a bit to
include cats. Try a search argument like:
pet door cat dog and let's just stick with:
for now. Have you tried that? Google Patents does not allow us to select the patent Abstract or Specification only. So let's go to:
and enter the search argument to search the
Abstract of the patent database only. The search argument (just copy and paste) will be:
ABST/pet and ABST/door and ABST/cat and ABST/dog
Now while you are there, change the search argument to search only the
Specification:
SPEC/pet and SPEC/door and SPEC/cat and SPEC/dog
The
Title and the
Abstract are where you want to search first, and then the
Specification. Play with that for a while and
see if ideas are forthcoming.
