Except owning a console or game is technically not ownership in the traditional sense that most people understand it as--it is more rather a license to use the product in a very specific way, and not in other ways that allow for reverse engineering, etc...
Still hasn't stopped all the fake NES and SNES classics from being sold everywhere from Ebay to retail kiosks in malls, though, for all the good laws seem to be doing...
I which country does buying hardware not constitute ownership?
Certainly not in the United States. Here ownership means ownership and in legal way is buying a game console anything like purchasing a license.
The day game companies start licensing out their hardware is the day I stop giving them money of any sort.
I can do whatever I please with the things I buy as long as I do it privately.
The notion that you might not actual own what you purchase is a dangerous one in general because it give manufacturers too much power over the consumer.
At what point are corporations not allowed to say they own the products you bought from them?
That would never fly in the US. Primarily because part of our patent and copyright laws includes measures to prevent such actions because they stifle innovation.
Take the clone NES consoles that have come out.
Those are all legal because the patents on the hardware used in the NES all ran out.
Now that doesn't mean you can recreate the original NES hardware exactly as it was, but you can make a similar machine that has the same hardware specs with no issues.
Not sure if that's the same case yet for the SNES, but eventually it will be.
