The other main change in Part 1 is the definition of "essentially derived variety", referred to as an "EDV". This is a new concept introduced by UPOV 91. If a new variety is essentially derived from an initial variety, then the rights holders of that initial variety also have rights over the EDV and they will come between them to some kind of agreement as to how those rights can be exploited. The definition in the introduction version was, arguably, quite narrow in an attempt to provide more clarity to what is a somewhat ambiguous definition in UPOV 91. Ultimately where the select committee landed in response to submitters was that, actually, it was better to leave the UPOV 91 as it was, as our trading partners have done. So the select committee made that change to the bill.
