Why would anyone believe that spare parts would need to be provided at cost? I’m a proponent of right to repair, but that would be an absurd over-step (and be a strong force to ensure that no spare parts are available to anyone).
Typically nobody would actually go through with placing any orders beyond that point, unless they’re the pentagon.
I don’t think anyone suggested manufacturers could get away with lying all the time.
my company has looked into spending billions for a chip fad of obsolete processes just to get some no longer in prodction parts. So far not worth it.
Businesses previously and will continue to negate it in practice, sometimes for legitimate reasons and sometimes not. And most of the time nobody outside of a small group will know for sure.
The cost for the part at the factory for 1,000+ units is radically different than the part for your one off garage build.
Many years ago I was servicing Maserati GranTurismos and Quattroportes of which some use a ZF 6 speed auto transmission. Since the same transmission is used in Land Rovers, I would buy parts from the Land Rover dealer which was nearby. One time I went there and they didn't have any fluid for the transmission for Land Rovers, but they did for Jaguar. The fluid was identical, but on a different shelf, and cost a lot more. The parts department said that Jaguar uses a 3rd party parts distribution contract in North America, but Land Rover does it in house, so every Jaguar part, of which many are identical to Land Rovers, costs more. They could not just bill out a Land Rover part internally to their own dealer to service a Jaguar either (they were a franchise that repaired both).
The main point I made is the upthread summary (which appears to be unreviewed ChatGPT spew, adding noise rather than signal to the discussion) of the law is incorrect in an obvious way that the actual bill is not.
The intent of a patent is that you invent something useful and get a temporary monopoly over it as the incentive for the invention. The premise is that the value of the patent is proportional to the value of the invention, and therefore the incentive we want to create for inventing it. If you invent something which is no improvement over the status quo then nobody is going to pay you a premium for it.
The problem comes when you patent an interface, like the connector between a razor handle and a blade. Because then even if the connector is nothing special, the replacement blades have to use that connector and then you get artificial demand for the connector, not because it's such a great connector but because the customer is in the market for blades for their existing razor. It's a mechanism of cheating the patent system by collecting a premium disproportionate to the value of what you invented.
This is even worse in tech products because a phone costs a lot more than a razor, so if you need a part, the amount they can stick you for because there is only one place to get the part is proportional to the value of a $900 phone instead of a $7 razor. And on top of that, they're not trying to sell you replacement parts, they're trying to turn your existing phone into slag so they can sell you a new phone.
Which is why the most important thing is that you can get repair parts from third parties, who both provide competition for parts and actually want to sell them because their primary business is selling repair parts instead of selling new phones.
That's the only kind of example I can think of.
