If I was him...
I'd smile sweetly and have my lawyers state that Crapple stop using any chip that has any of my IP in it tout suite or pay me a big fat royalty for every single one that's sold. $100 per individual chip should do it
Because if Crapple have given up on a lawsuit that means they know its got as much chance of success as the Electrobigot has of being likeable, ie zero - which means they've wasted everyone's time, caused innumerable amounts of unnecessary stress to lots of people for no reason and generally been Apple grade assholes all round. I'd want to make sure they think twice about doing it again for the n-th time...
Nothing personal you understand...
