- This patent is actually one a moderate number on which Espacenet only gives exceedingly slight data. In fact, the filing date and patent number are all that we may absolutely gather from the addition on which we have more data. That the patent's original title matches that of the addition is a matter of extreme likelihood, as is the year granted, in this particular case, and indeed, even that the patent was filed in collaboration between both of the inventors named on the addition, even this is only a matter of extreme likelihood.
Espacenet does give IPC and CPC classification data. We do have every reason to believe that the patent existed, of course, and its having been granted is a matter of significant likelihood.
