> But, it needs to be for real inventions that took time and effort to develop thru costly processes

Be careful with this. I have a friend who has a patent (might be expired by now) that basically came to be because I asked him a question about a battery charging design he wanted me to write some code for. It didn't make sense to me but in the process of explaining it, a lightbulb went off in his head and that was the basis of the idea. It's actually funny remembering the sudden excitement crossing his face as he realized he was on to something no one had thought of before (he had years of experience in the field).

At the time I was already an experienced EE and I can assure you that the idea was definitely "not obvious to a skilled practitioner in the field" but yet it didn't take much development (we had it working about a week later).

Found the patent here: https://patents.google.com/patent/US5894212A/en

[edit] looks like it's been cited by quite a few other patents since then! I never asked him how much he sold it for.
