You are exactly right.  Once a method or technology has been published and sent to
public domain cyber space, I don't see how it could be patented.  Of course it must be
referenced if used.  I once looked into patenting a mixture of GMA which was developed
by a Polymer Chemist I was working with, the patent lawers told us that if the mix or
even a similar mix had ever been published we could not patent it.  My understanding
was that you had to prove to the patent office that you invented this product, so my
question to the company who claims to have a patent on Tyramide use, is did you not
disclose all of the published material already out there on this substance?
If they do have a patent I think this has been given out without proper
consideration.  I think patents and FDA approvals are being given too easily these
days.  We have FDA approval of  IHC methods for tests that are used in determining
treatment for patients when these tests have little or no room for error in an
enviroment not set up to operate without errors (histopathology).
My opinion.
