The submarine patent person finally realizes how everything works, modifies his claims, and perfects the patent. Oh, you've mentioned it, Mr. Lehman, many times, and in a loud voice. And this is your biggest lie of all. Lehman's notion that inventors deliberately delay patent issuance, willingly not getting revenue and letting their term expire is nonsense. Submarine Patents, a phrase that came out of Japan, first appeared in Lehman's 1994 testimony to Congress.
Problem is that no one has ever managed to find one.
Detailed study of decades of patent patent filings shows that submarine patents probably don't exist, and certainly are not a problem. Published response to interview. Lehman resigns .
