I have found the patent and it is an excellent writing. It has two independent claims, (one for apparatus and one for method) and – holly patentito! – the claims do cover the pond basket like structures (with an addition requirement). The patent attorney must have been a very good one to push the claims thru.


Yes, folks, depending on what you are doing, it is possible that you are infringing on this patent.

The patent was filed in Apr 1992.
