So Sotomayor knows where to

So Sotomayor knows where to find a sugar mine? and a flour mine? Good examples of things that do not normally exist independently in nature but rather which must be extracted and purified to be of much use, i.e., the products of tranformation. She really is very simple minded. Personally, I would spare myself the adventure of having cookies at her house. Likely to comprise shards of cane and even whole insects for their interesting colors.

And speaking of saps, precedent is indeed that you can't patent naturally ocurring sap (as a composition of matter) but you can most certainly patent uses of sap, even without further purification.

Sotomayor said nothing to

Sotomayor said nothing to that effect, and her analogy was fairly accurate if not a bit simplistic. Ultimately, it is true, DNA is just a natural molecule extracted from another material (just like sugar), and therefore the DNA itself should not be patentable. Just as she said, one could patent uses for the DNA (and people have quite a bit), and just like Breyer said, one could patent methods for extracting the DNA (and people have quite a bit). But not the DNA itself.

"but you can most certainly

"but you can most certainly patent uses of sap, even without further purification."
I wasn't aware of this. Is it true that patent legislation allows for a novel use of a naturally occurring substance without processing. Could one patent a novel use of water?
