There were several comments from Dagmar and Francois. I tried to integrate.
Further, I was a little cautious on animals. I deleted the examples which might have caused debates about revoked or lapsed patents, I kept it more general.
I took over the idea from Dagmar to summarize the first part for the petition. I think we should have an explanatory text (first part) and a shorter text which is the real petition.
There was the idea to demand to restrict the patents to regulated genetic engineering. I would avoid this, because these legal frameworks are separated and I think it is important to explain this (again) to those which want to have random mutations to be regulated as genetic engineering. There is not much in common between GMO regulation and patent law.
on the text for the visual. How about:
Internationale Konferenz um Patente auf Saatgut stoppen!
International Conference to stop patents on seeds!
I continue to work on english verion and draft PR.
