Except it is a copy - Paddy still has the full order he placed with the manufacturer.
Press charges against the factory owner, not the people buying locos from Ebay - sure how are they to know anyway?
Same as going after the drug dealers instead of the users/addicts
I get the whole Intellectual Property (IP) thing - the factory are the ones running off extra copies to sell themselves, taking all the profit. This is who should be charged.
Example - One of your relations knows you are into modelling Irish railways. As a present, they want to get you a model loco. Seeing them sold out on the Irish shops, they go to Ebay, and lo and behold, there's Irish locos for sale. They purchase one from the Chinese seller - should they be charged with handling stolen property? Should you if you received it from your aunt/uncle whatever? Daft...
