Pot Patent # 6,630,507

Patenting plants is legal and has been since The Plant Patent Act 1930s. Oh wow, look at that. If your a history buff you should go back and look at everything that happened in that period. 1930s isn't that before we knew about DNA?

Yes corperations like Monsanto and Dupont can patent plants, and they have been for a long time. You know cannabis wasn't the only plant outlawed in the US. The Native Americans had some very great strains of various colors of cotton that were pest resistant and more attune to the soil. These strains of cotton were eradicated when the new white strain of cotton was developed.

There may be some connection between the plant patent act and cannabis.
The Native Americans were advanced farmers, it may be that they were genetic engineers before biotechnology. Native history has some record of a "Mother Plant" I believe Cannabis is the "Mother Plant"

The native's would use certain plants in their garden to ward off certain pests. Now in science we are discovering that plants communicate signals to each other and the organisms in their environment.

I have bought patented roses, so I am not so sure that is a correct statement.

Each and every genotype potentially could be patented, but would take genetic testing to be able to do so. Way beyond what my financial means will ever be.

It is such an interesting topic tho.
