No. In 2002 the watch manufacturer Rolex brought an action against Ebay in order to stop all trade in its brand on the platform and thus to prevent the sale of copies, but lost the case in the autumn of 2002. In March 2004 the decision of the German Federal Court of Justice (Bundesgerichtshof) was available: the platform operator does not have to interfere in the listings, because it merely acts as an intermediary between seller and buyer. A different outcome would have had far-reaching consequences, since any kind of trade in Montblanc writing instruments could then have been prohibited as well.
Trade mark proprietors, on the other hand, have far-reaching means of intervention. Through the programme for verified rights owners they can report unlawful auctions; the listings are then deleted and the seller receives a warning. The platform passes the seller's details on to the rights owner, so that further legal steps are possible. For Montblanc items it is Richemont International S.A. that acts as the rights owner.
Many manufacturers of luxury goods now cooperate with the platforms, which is why copies are becoming rarer there; Montblanc likewise carries out random checks and takes action against sellers offering copies.
