Unclear

This data group is evolving as a natural response to the issues we face vis-à-vis the handwriting legibility of patent agents, on American patent originals in particular. This entry in the patent agent field on patent pages usually stands alone, though it has occasionally been mixed with attempted decipherments drawn from the original documents. The data displayed below is in no way comprehensive.
