What follows on this linked Biddington's page is a sort of vintage chart for patented objects: it cross-references the patent number with the year in which the patent was issued . If an item was produced over a long period of time, this chart will tell you the earliest date it could have been made . If an item was only a flash-in-the-pan, then the age becomes quite specific .
The numbered sequence runs from GB1 of 1617 to GB14359 of September 1852 . Before October 1852, details of granted English patents were simply recorded (enrolled) in the Patent Rolls at the end of a long, cumbersome and costly application process . No numbering system was in place .
Dating British Clocks by Their Patent and/or Registered Design Numbers . Parts found in many British clocks may be marked with one or more British patent numbers or registered design numbers . However, the British patent numbering system and the manner in which patent registration was displayed on the item is much more complex than the American system .

The patent issued date then will give you an approximate age of the antique . If you used patent pending numbers like we did for this Hotchkiss stapler, then the age of the antique is probably going to be earlier than the patent date . So for our example we looked up the pending patent number "2117741" and it was patented on May 17, 1938 .

The dating of British designs during the Arts & Crafts, Art Nouveau and Art Deco periods is often assisted by the use of Registered Design Numbers . This was a system which came into being in 1842 and started to decline in the early 1930s .
