What!?!?!? Soccer blue.
I used to wander through I brainstorm. I ended up designing a circuit around one chip I found in the early 90's. I got an article published (and some cash) out of that one. I may have been able to patent the device, but was a poor broke college kid at the time.
I built alarm systems from the stuff there. You can buy better stuff now from China that did what mine did in the 90’s. Cheaper as well.
Patents are not all they are billed to be. Look at Polaroid suit against Kodak over the instant film. Would have been farther ahead to put the effort into marketing.
