            Jewelry Patents 1961 – 1971

            Dotty’s friend Mary Walden-Till of the UK is responsible for these pages of utility patents. Her dedication in searching the US patent website and willingness to share her findings is greatly appreciated.

            Definitions:

            • A Design Patent only protects the appearance of an article, not it’s structural or functional features, and is usually used for decorative items.
            • A Utility Patent protects the structure and function of the invention.

            1911 – 1929
            1930 – 1939
            1940 – 1959
            1960 – 1979
