The quid pro quo for granting patent protection is the making public of the invention to a degree of specificity that one skilled in the art CAN repeat the invention.
That is the essence of the deal we make. IF the patent does not sufficiently disclose the invention then the patent should not be allowed by the patent office nor enforced by the courts.
Eg. Say an ingredient is left out of the secret sauce. That would be a fraud on the patent office or inequitable conduct sufficient to invalidate the patent.
