As discussed in the comments section last time, the problem with my Mom’s and Grandmother’s “invention” back in the late 1980s was that it wasn’t an invention. It was just an idea, which cannot be patented.
All patents start with one, of course.
Dog waste on the streets of any big city, like New York, is a very special problem in the summer time, when the city becomes a tropical “paradise,” albeit with world-class dining and entertainment, together with daily bus tours. Before the “pick up after your pooch” laws were enacted some 15 years ago, the heat could “cook” the waste, rendering the streets virtually unpassable to pedestrians. Except for real New Yorkers, of course!
As one reader, or expert, commented two weeks ago, dog waste will naturally decay into dust. But this process can take weeks, which would seem like centuries to New Yorkers. The public interest is to get rid of it instantly. It would be possible, for example, to torch it with flame throwers, but this could introduce new, stranger, potentially unsafe possibilities.
