Utility patents show how a mechanism works... Design patents are for the way it looks. Jim Katz downloaded almost all the jewelry design patents from 1867 through 1965 and after 1955, the amount of jewelry design patents tapers way off in comparison to earlier years.

Coro and Trifari are responsible for almost half of all jewelry design patents up through the middle 1950's. Philippe for Trifari patents seem to disappear after about 1954, and Katz for Coro after 1965.

Jewelry Design Patents - (all approximations):
From 1858 - 1925               1,203 Jewelry Design Patents Granted
From  1925 - 1955                6,528 Jewelry Design Patents Granted
From 1955 - 1965                  450 Jewelry Design Patents Granted

As you can see from the following information, patents are still being granted but after 1965 the jewelry design patents from all the large manufacturer's all but disappeared.

All patents  - not just jewelry - (all approximations)
By 1971 there were approx.  220,000 design patents granted
By 2003                                470,000 design patents granted
By 1971                                3,600,000 utility patents granted
By 2003                                6,670,000 utility patents granted

PLEASE NOTE: Regretfully, it is no longer possible to respond to individual questions regarding jewelry history, identification or value, or to offer written or verbal appraisals or opinions. The demand for this kind of information is absolutely too overwhelming for one dealer to fill. 
I love jewelry, but appraising and selling are two entirely different businesses, and I choose selling as my business.

Instead, articles are added on a regular basis to JEWEL CHAT on line Magazine, a wonderful reference for  information on many makers and styles of vintage jewelry.
