I was just on Dutch Passion's website looking for the Automatic version of Frisian Duck. They have it listed as AutuDuck, with a registered trademark symbol. How can they do that when the term AUTODUCK has freely been used for several years. It is a common vernacular for any auto that has ducksfoot leaves. Further investigation into their site, and I see them slapping trademark symbols on auto versions of other company's seeds, many of which have been created and sold by others for years?
