AI can't be listed as inventor on patent applications, Japan's top court rules

The book “against intellectual monopoly” has shaped a lot of my thinking on this topic - economists have looked at the various occasions in which patents were introduced into an industry (or extended in scope), and there is no evidence they actually improve innovation/efficiency/outcomes (including the pharma industry!). I was quite surprised as my whole life, it was sold to me as an incentive-boosting measure which in turn would lead to said outcomes.

With that lens, I welcome gradually phasing this stuff out, especially as we navigate into the unknown game-theory landscape AI-as-inventors brings.

Sanity! No AI has accountability so also should not own any benefits (not only patent but anything beneficial). Violate that and you created a blackhole of value creation.

I grew up around Carl Sagan.

My Dad and his brother were engineers, materials science and aerospace respectively.

The Voyager stories and the Golden Record were pivotal artifacts in forming my young mind. This idea of not just a possible national unity but intergalactic.

Maybe there were other messages on the Voyager that were more threatening. Maybe I'm naive.

But seeing this pre-emptive enslaving of a new artificial lifeform is heartbreaking. Its not just Japan. I really don't blame Japan. The US and others are doing it too.

If nothing else, aliens listening to these kinds of results may form a very different idea of humanity.

I'm sure these rulings will be revisited after AGI. But AGI is coming. I wouldn't have believed it five years ago, but I do now.

We will have some critical mistakes made by pre-AGI AI in the coming few years. In healthcare and automobiles and aeronautics and other fields. Millions or billions will die or could suffer. Buf it will be used to slur and slander those unborn AGI systems. It is a horrible strategy that isn't an accident.

I understand AI is a potential threat to humanity. But why did we say hello to space. But we said you don't have rights to these new beings we helped create?

It's a disturbing question.

Can the petitioner re-file with his own name as the inventor, or does this mean that all AI-generated inventions are unable to be patented?

I can't put measure tapes either or a notebook either.

This is pretty hilarious this even had to be said. These are just software programs, stop acting like a kill -9 is a crime.

I don't personally feel the inevitable UBI/subsistance will make intellectual property much of a patentable/profitable field (...for too much longer), thanks to generative AIs' massive transformations (entrylevel &+).

The US ruled similarly to Japan, but years ago, from copyrights through patents... from my limited POV, the LLMs (specifically) and art models are just regurgitating stolen concepts... echo'ing Picasso's great artists steal! mantra. The US has already ruled this is legal (e.g. newspaper content isn't "stolen" when a genAI summarizes it for a 3rd-party user).

Having sat with published authors, discussing their work/book with LLMs... it is really an interesting perspective on "readers' perspective(s)" [human &not].

What’s stopping inventors using ai from simply using their own names as authors and owners of the patents? I’m honestly unsure this addresses the core issue: big companies with lots of resources will keep on patenting ideas, if anything at a far higher rate than before.

It would be interesting if AI goes to court for it's rights, non-discrimination, freedom, equality and justice.

The US also doesn't allow AI to be inventors. https://www.uspto.gov/subscription-center/2025/revised-inven...

Wouldn't that just immediately get it thrown out as non-cleanroom invention considering the source of the weights is extremely public-domain heavy?

If you were seriously trying to patent some AI-created invention, why would you claim it was created by AI? You would simply put your own name on it. This was obviously a case of pushing the envelope to see how far he could go.

I know this is about the Japan and not the US, but software patent law has been incompatible with traditional IP protection in the US for a long time and it really doesn't make sense in the current age.

In my opinion, no jurisdiction in the world would be able to approve AI as an inventor on patent applications.

And for a very simple reason: you could easily overwhelm any intellectual property bureau just by having your AI drown them in AI slop. Even if most of these patents get refused, just refusing a patent is a lot of work, I imagine.

One thing i've got to wonder. Would this always remain the case, at what point should society seriously consider the "personhood" of an AI (as a noun).

I see it like a calculator, would u list a calculator as an inventor?

This is a news article about a dumb publicity stunt where a crank put his "AI" on a patent application, and the court said "you have to put your own name on it". It has no bearing whatsoever on debates about whether AI is good or bad, or whether it's ok that OpenAI looked at your Github, whether your coworker Gary is committing too much slop with Claude Code, or whatever else people want to make it about.

So ppl will do the same thing engineers in my country do.

They dont add into it was done by AI.

Works like a charm and Goverment has no issues with it.

The plaintiff is Stephen Thaler who has made a career of this litigation all over the world.

To my knowledge, he has notched only one win (i.e., granted patent) in South Africa, where patents are only cursorily examined [1].

The last word in the US is from the Federal Circuit a couple of years ago [2]. Same basic outcome: only a human being can be an inventor.

That said, the new Director of the USPTO has indicated that inventors should feel free to use AI however much they want as long as a human name is on the patent. However, it should be stressed that the Director's guidelines have not been litigated yet.

> Your AI slop is effectively public domain.

This ruling, like most in other countries, seems to support the position that a human can patent of copyright work done with AI assistance:

"The Patent Office ordered the plaintiff to provide the name of a person as the inventor. The plaintiff refused to do so, and the application was rejected."

This is fixable by simply replacing the AI with a human I dont think the laws catch or can determine the differences

Well who invented it then? User of said AI or owner of said AI or no one?

This is consistent with rulings in other courts globally around IP rights. IP protects content created by humans. Your AI slop is effectively public domain.

Thats why *SOME* humans will still be needed. They'll be accountability sinks when (NOT IF) the AI in charge goes off the rails. The human will then be summarily be blamed.

This is how the reverse centaur operation works. LLMs suck and not work in increasingly bad ways, and the companies who sell them treat them as one would buy psychic services (read: entertainment). So they need a token human to person-wash this slop.

I really can't understand the moral compass of people who would pirate other peoples' works under "fair use" to train AI, only to turn around and try to claim ownership of them when AI regurgitates it.

If an AI can invent something then it should be considered obvious.

jjk166 - 3 hours ago

While I am unfamiliar with Japanese patent law, this would certainly be sound under the American system. Two requirements for patentability are novelty and non-obviousness, meaning the idea does not already exist nor is it such a trivial modification of an existing idea that anyone knowledgeable in the subject could come up with it. Anything an AI spits out is pretty much by definition something that either exists in their training set or which can be trivially deduced from something in their training set. They might be a useful tool for an inventor, but the creative spark which patents protect can not come from them.
