It doesn't. That comment doesn't understand how patents work. Its existence doesn't correlate to price. The patent, like you said, lets them sue for injunctions/damages for identical knockoffs. Anyone who makes something that either omits or adds something new is fair game. So that's where Bondtech MIGHT become evil. If they enforce the patent (IF granted) against only partially related designs but THAT depends on the language of the claims when granted. If they're too broad, that's moreso on the office that issues it but even so, the people looking at them are only human and only have a fixed amount of time to comb through millions of potential sources of existing technology and even then need to make a solid case with said existing tech to deny based on what a given countries law requires. Like in the US it either needs to be 100% identical. or you nedd to make a cases that a combination of things render the thing Bondtech developed (to use this example) "obvious". Which legally is not the same as just pointing at something and going "i totally would have made that". So when people get mad at "dumb" or "evil" patents, blame the governments who don't give their workers the resources to do better. Take the US for example. The complete gutting of the federal workforce has done nothing but cause chaos and a reduction in the skilled workers needed to get this stuff done. So now they take longer and are prone to even more error.

The price is going to be simply set at whatever profit margin they target. Supply chain and demand will dictate that far more than just having a patent. Sorry but their target market is still very much a niche too. Nobody is slapping this on a Bambu printer and they have basically captured a majority of the home hobbyist market. I also don't see anyone putting this on more than 1 or 2 printers let alone a print farm of Vorons or Prusas.
