I'm confused about the patent renewal problem.
He got the patent in 1981 and then the 'same year' Paul McCartney pays to renew them?
And then apparently in 1988 he's supposed to renew them again and doesn't have the money.
What's the story here?
I saw that too... and wondered. Usually patents were 17 years, I think. I wonder if the reporter has confabulated the need for cash to DEFEND his patents... if he could not bring a suit against an infringer, his patent could be invalidated due not not pursuing it agressively.
