Trifari PAT. PEND. This is one of the earliest Trifari marks you will see (there were a couple of earlier signatures, but they are quite rare). Prior to 1955 the U.S. copyright law did not extend protection to jewelry designs, so the major manufacturers, who employed talented jewelry designers, protected their investment with U.S. patents.

1936 While Trifari's head designer, Alfred Philippe's, actually joined the company in 1930, these were the first patents I could find of his on record. The first one is for his version of the clip-mate which he actually called "lingerie clips". It was patent # 2,050,804. 1937 Alfred Philippe's first design patents on record were this year.
