Strange article over that the Washington Post. If I read this article correctly I come away with the following.
1) Spam junk email is the reason why these little cars are hyper hot.
2) Tomy & Hobbyco are banking on copywrite to curtail clone sales.
#1 makes no real sense.
And #2 did they give up on the FCC side?
A copywrite is only for a specific designed etc. A RC car is too vauge to patten even under US laws. And with the unlimited different designed around would take every dime they have to even try to put a stop in the flow. Time will do it for them. Esp if they went to stop RS.
