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.
