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 says that 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
