There is a story that Tesla didn't patent anything. That it was all Westinghouse. He was allowed in Tesla's labs, and so basically drew down what Tesla had made work.

I feel this may be true, because of the patents I have seen do not feel like Tesla's work. If Tesla did them, the focus would be on the part that made it work, not the mechanical enclosure, etc. The voice in the patents do not seem to be the voice that Tesla wrote in.

None of it adds up. Except for that book, that you see Tesla reading in that very famous picture Tesla set up /posed for.
