Patent expiration into the public domain is already “the ruling class seizing inventions” in the same sense (in the sense that it isn’t — in both cases, the goal is to make nobody profit from the patent any longer; not to transfer the profits to the government.)

Patents only exist as a concept, as a way to construct an equitable compensation for invention, to incentivize invention, that allows the market to determine what the total compensation over the legal lifetime of the patent should be, by licensing it or refusing to at given prices.

Insofar as an equitable compensation / patent “value” can be determined analytically on a one-off basis, you don’t need the patent system; the government can just buy out at that price, and the same goal will have been achieved.

Theoretically I agree completely. However in practice, analytically figuring out a dollar amount that isn't over or under paying seems nearly impossible. I fear that the gov would be buying out a lot of useless patents. That would also create an even bigger incentive to get BS patents through, because you don't even have to prove the value in the market, you just gotta convince a bureaucrat that it could be beneficial to humanity.

Why do you expect this? This doesn't happen with existing uses of eminent domain — lobbyist landholders aren't going around convincing the government to buy out useless land to their profit.

Eminent domain on real estate is only used as a last resort — it's invoked to buy out real estate where the government has some pre-existing plan that requires the use of the land; and there's no reasonable alternative to using that specific land; but the owner of the land doesn't want to sell it to them on the open market for a reasonable price (i.e. the price that they'd charge an arbitrary private buyer.)

I would assume eminent domain on patents would be the same: it would only be used if the government has a top-down plan that works out to require licensing a specific patent; with no reasonable alternative; but the patent owner is being obstructionist to licensing the patent for a reasonable price.

If we are only talking about patents for whom

Then I fully agree. In your previous comment where you said "you don’t need the patent system;" that threw me off thinking you were basically talking about every patent. Where you said "insofar" at the beginning of the sentence, I interpreted that to mean essentialy "since" or "because" but I see what your original intent was now, and I think we are in complete agreement.

Exactly. Ideally we wouldn't have patents, but would have a "Star Trek" luxury space communism economy. Until then, if an invention proves to be highly beneficial to society after a few years, I would entirely support governments buying out patents early. In the end, information is a public good (non-rival, non-excludable), so let's start treating it that way.
