“Where judgment was given in an English court that a patent, whether English or European, was valid and infringed, and the patent was subsequently retrospectively revoked or amended, whether in England or at the European Patent Office, the defendant was entitled to rely on the fact of the revocation or amendment on an inquiry as to damages in respect of the unamended patent.”
