Well no system can work that way - if judges in court were overworked and making invalid judgements, then the legal system would fail no matter what kind of laws you have and no matter what police does
An overworked Supreme Court does not lead to more Supreme Court decisions.
Former USPTO patent examiner here. I'll answer why an overworked USPTO will lead to more patents at present, but I make no claims that it should be this way.
The effective default is to grant patents. Why? Because the examiner has a finite amount of time for each application and has to have some sort of justification for a rejection. Unless there are some formal problems with the patent application, "I couldn't find prior art" means that a patent will be granted. Examiners could try "official notice" to basically say that they don't think it's novel or non-obvious without providing a reference, but that's easily defeated by attorneys. Examiners must provide a clear justification for a rejection.
If the amount of time an examiner has is too low (and it's far too low), that increases the chance that no prior art will be found, and consequently increases the chance that invalid patents will be granted.
Contrast that with the Supreme Court: The Supreme Court can decline to see a case. You can't do that as an examiner. You can try to have an application transferred, but that will just give it to another overworked examiner!
The path of least resistance makes appearance once again. If we don't understand that this guides the default final state, we would argue about nothing constructive.
Interesting. Did you enjoy it? Why did you stop?
I stopped for the simple reason that the job was far too difficult, and poorly paid on top of that.
Suppose an institution is overworked, it has two options - long queue or rush the job.
Courts understand their role is important, so you have a long wait, but they d0 the job properly.
Patent office, perhaps, rushes the job. Now whether they issue too many or too few patents is maybe equally bad, in my view, it’s screwed up either way.
And the wealthy and powerful use that wealth and power to influence how government functions.
Thus, the current situation.
