on initial rejection of claims of RSA patent
Diffie, via "L.":
# No. But after all, the RSA patent was filed from MIT by people
# (R, S, and A) that I didn't know well till much later. There may have
# been some hankey pankey I didn't know about, but I certainly don't
# recall the New York Times article you refer to. The statement that
# ``They just got the application back rejected.'' Doesn't sound right
# to me. I presume that the Patent Office has to state why an
# application is returned. It's decisions, after all, are a constant
All four of the PKP patents mentioned in RFC1423,
Cryptographic Apparatus and Method
("Diffie-Hellman")............................... No. 4,200,770
Public Key Cryptographic Apparatus
and Method ("Hellman-Merkle").................... No. 4,218,582
Cryptographic Communications System and
Method ("RSA")................................... No. 4,405,829
Exponential Cryptographic Apparatus
and Method ("Hellman-Pohlig").................... No. 4,424,414
had all of their claims either "rejected" or "objected to" on the first
pass by the patent examiner. I have been told this is not unusual.
The patent examiner gave reasonable technical reasons whe he rejected
them. Nothing looks fishy to me, that is part of the record.
I have a copy of [almost all of] the "full wrappers" on these four
patents, and am making them available to the CA cypherpunks (CA,
because I live here). (They're not online, there's a lot of
handwritten pages & annotations & forms that would not OCR, and it's a
6" stack of legal paper, so it's not easy for me to provide them
online, sorry.)
