others have been investing into biotechnology in such a way that
patents have been taken out on indigenous plants which have been used
for generations by the local people, without their knowledge or consent. The people then find that the only way to use their age-old knowledge is be to buy them back from the big corporations. In
Brazil, which has some of the richest biodiversity in the world, large
multinational corporations have already patented more than half the

To be patentable an invention must be novel, inventive and have a
commercial use. Controversially though, the US and European patent
offices now grants patents on plant varieties, GM crops, genes and gene
sequences from plants and crops. The current WTO patent agreement,

who want to have it reviewed, but are being somewhat blocked by the
wealthier nations from doing so.
