"Under Section 73(1A) your patent has been reviewed by a Deputy Director on behalf of the Comptroller who considers that claim 1 is not novel in view of US 3485037 and also not inventive, in particular in view of US 2007/175209 and EP1439310.
Before beginning revocation proceedings, you are invited to amend your patent and/or to comment on the citations before [7 October 2015]."This is the first time the new provision under section 73(1A) has been used to initiate action. The proprietor, JC Bamford Excavators Limited, now has two months to decide what to do to try to avoid getting their patent revoked. I will, of course be keeping a close watch to see what happens.
