Add on a "use it or lose it" policy and I'm onboard. If the patent holder isn't building products with their IP or licensing it as the original author than they shouldn't be allowed to hold it. It would disable "defensive" patent strategies where companies don't patent their actual technology, but the path to it, which is against the spirit of patents, and disable patent acquisition as an IP strategy. Meanwhile companies like ARM, which live off IP licensing but wouldn't be punished because they're the original patent authors.
