Been down the patent road. A serious effort at writing the patent is about as fun as writing a published paper. Over and over and over again till everyone believes the i's are dotted and the t's are crossed. It is very enlightening to view prior art patents kind of humbles you down. Also becomes a matter of opinion. Someone technical in the art, in my case me, and someone new can come up with different lists of pertinent literature. Shakes your confidence a bit. I my case the patent was with an organization and I was one of several names on it. (But i was the poor bugger who got the short straw and had to write it!) I wasn't pursuing the 'Murican Dream so I wasn't facing the typical stakes and objectives.
Many times people have told me to patent my power ascender. Knowing the art, and the hassle I have no appetite for it and it remains camera shy. Heading up 8 years now. I have described it verbally and would feel sufficiently whatever(?) undefined(?) if it ever became a thing knowing I originated it. I'm a simple folk.
On the other actual patent it came to my attention someone else was pursuing doing it commercially. I informed the organization and they said it's up to you to do something about it. Not the situation for me. Washed my hands of it.
Listen to the beady eyed dude on Dragon's Den / Shark Tank to get your business mindset. "You're a cockroach in this space waiting to get stepped on" "Show me the money"
There is a certain satisfaction in knowing you got the only one of your special whosit, too
