The example from Germany was specifically referring to lawsuits regarding the sale of grain.
I did some research on the subject, after I spoke with my local member of Parliament, and found that in Germany the regulation was adopted with an exception for smaller acreage growers, varying slightly. It's somewhat complex the way they implemented it. Perhaps that's part of the issue there; I'm not sure.
Saatgut-Treuhandverwaltungs GmbH, the organization in Germany that is responsible for the enforcement of UPOV 91 regulations, has made itself very hostile to small farmers. There are between 2,000 and 3,000 lawsuits against small farmers around this legislation. I can't speak to all of them, and I'm not familiar enough with how the legislation was implemented in Germany, but an Internet search regarding Saatgut-Treuhandverwaltungs GmbH brings up a lot of examples that can be looked to for that. Speaking anecdotally, I know that many small farmers are being harassed by that organization to report even though they fall below the threshold required for reporting.
Does that answer the question?
