Clarence Ernest Holt
Clarence Ernest Holt was an aero inventor whom patent data first has filing from Henryetta, Okmulgee county, OK.[1]
We have him later filing from Ada, Pontotoc county, OK.[2]
Incidentally, both of the patent documents we presently have on hand make reference to an earlier filing date 23 Aug 1918, using serial number 251184. Patent US-1918-1371204 results from the initial filing having been "divided", whereas Patent US-1921-1370445 purports to result from the early filing being merely "renewed". We are exploring these practices, both patterned cases and possible wildcards on page serial number. There is substantive difference in emphasis between the two patents.
