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.
