In Europe, a limitation in a granted patent that is later found not to have been disclosed in the original application leads to the revocation of the respective claim(s) (art. 123 (2) and (3) EPC).
What is the legal consequence of the same situation in the US?
Claim 1 after changes during examination: A car with 4 wheels.
The description is silent about any wheels, the examiner still grants the patent due to an error (or whatever).
Will the patent die or is there any remedy?
