Category:Techtypes
This category uses the form Techtype. These designations are pertinent to our Smart, or Advanced, or Classification Espacenet searches. A great deal of this material, pertinent to the years just preceding, and long-following, 1900, was found by way of this resource, largely using the designation "B64" (in the IPC and-or CPC fields), cross-referenced with of timespans of interest. The IPC and CPC categories were applied much later to the patent in the early-aero time period, not at the time of the patent application. We do not yet know when they were applied or by whom exactly. The parent pages over all these, to which the others link, is Techtype, and most of them are linked to Patent classification systems.
