The rules keep changing over whether plants or plant products
obtained by means of an essentially biological process are
patentable in Europe.
Under Article 53(b) EPC (and Article 4 Biotech Directive),
European patents shall not be granted in respect of plant varieties
or essentially biological processes for the production of plants.
Originally, this was interpreted to extend to plants and plant
products obtained by means of an essentially biological
process.
This was challenged in Broccoli/Tomatoes I (
G 0002/07 &
G 0001/08) and Broccoli/Tomatoes II (
G 0002/12 &
G 0002/13), following which, it was allowable
to have a product claim directed to plants or plant material such
as a fruit, even though the plant or plant material might be
obtained by an essentially biological process, which is not
patentable.
