There's a two part answer to that. They need to make sure an IP stays with a company a lot better. Nintendo acts this way because other companies will try every angle to get Nintendo IP. It got so bad in the 90's, the president of Nintendo of America was also the company lawyer. Look up Howard Lincoln.

The second part is having the companies provide ways to fix and maintain the equipment legally after it has been abandoned. Arcade collectors often have to break laws to get the info needed to fix a machine. There needs to be allowable way to keep the patent and IP but be able to rebuild the innards of machines.
