The stated goal at http://www.uspto.gov/about-us/organizational-offices/office-under-secretary-and-director/intellectual-property-iconathon was “ to create a set of internationally recognizable icons that will help increase communication around intellectual property.”
The word equivalents provided for the above symbols are:
Utility Patent*Patent Pending*Plant Patent * Pro Se
Invention* Maker*Intellectual Property*Design Patent
Infringement*Trade Secret* Micro Entity Inventor*Service Mark
The icons are imaginative and interesting. Are they sufficiently intuitive to be the communication tool hoped for?
