good question and one that has not been talked about as far as I know. I assume the J-3 has copies of the letters in their possession for sure or the" inventorship defense" would not have come about.
There was one letter from Fish that talked of separating the patents and he did "on paper". Then he went further to toot his own horn by basically saying his were the important inventions and Moores were secondary. I didn't like the letter at all.
What we don't know is how they proceded from there and I hope they then dotted all the i's and crossed the t's so that this subject or my "risk factor " is absolutely moot. joe
