That almost made sense in the age of the cotton gin. It does not any more. All patents are abuse. Always. Every time.
Case in point: you “invent” something (which is guaranteed to be something - or a combination of somethings - that are already extant, btw)… a corporation…
Already has a similar patent and crushes you with the sheer legal corruption and power that comes with ostentatious wealth.
Files the patent before or via other loophole supersedes your filing… and THEN crushes you with sheer legal corruption and power that comes with ostentatious wealth.
Either way, they win. And even if you win, chances are you’ve merely stolen some concept that should always have been public domain, anyway.
You see this as a way to fight against wealthy corporations, but no matter how you swing it, it’s theft. It’s plain old theft from society and the public… and the bigger and wealthier you are, the more you can steal. Just because “little guys” can sometimes engage in such legally-protected theft doesn’t make it any less theft.
