They have been researched and are called "X-Patents" when found. Not all have been found and consolidated into the new list. Officially patents of this era have an "X" at the end of the patent number, but that is not always the case. Research online often put the "x" in the front of the number, and we have used that system Fractional numbers are designed to update patents, but keep them in sequential order. |
