Ugh Lego and trademarks. My wife and I had Lego threaten to sue us for trying to import "legos" of mass destruction, it seems. We ordered a lego-compatible kit, which is ok I think, since it's only the lego figure that is patented Lego, the logo and name of course trademarked to Lego, and any brand cooperation to respective rights holders (eg Star Wars).
However, a kit without Lego names or logos, and without Lego-figures, and without any branding or copy of existing Lego-kit, should be ok.
But no. In some way, our customs withheld the package and we had lawyers for Lego threaten to sue us if we claimed rights to the package. They attached the Lego figure patent with the threat. We said, burn it, forget it, and acknowledge that we can sleep at night again please, but they forgot the last part.
It was a kit worth about 10€, and we have hundreds of €'s of Lego. Now we've stopped buying Lego. Also, less plastic crap.
Not to sound bitter, but the big friggin majority of kids toys industry is shit and the world would be a better place without it. Sorry for the steam :S.
