I bought some Wise Hawk mini blocks (about 100 pieces) for me and my family in Hungary online from China. But the customs office has seized it, saying it is an unlicensed copy of LEGO and I committed a crime. I asked my supplier from Alibaba, who told me these pieces are of a smaller size than LEGO and thus need no licence. But LEGO wants to sue me and want to destroy my stuff at the customs. Is that true, did I commit a crime when I ordered this toy online?
AFAIK you did not commit any crimes, as buying conterfeit products is not considered a crime - even if your wares were counterfeit, but they are probably not, since the basic brick design is not patented anymore and these blocks are decidedly made different and incompatible.
Can you post the original message you received from the Hungarian customs agency? I happen to know Hungarian, and others might too. Maybe they are misinterpreting something.
Anyways, I'd answer the customs agency by telling them about the intentional design differences, the expired patent of the studs-and-tubes brick design and attaching the answer you have received from your Alibaba seller. The surefire way would be to acquire the assistance of a local lawyer, but cost-wise that would probably not be worth it.
