Protected emblems and symbols
We are unable to register any sign as a trademark if it consists of or contains an emblem that has protection under an International agreement. One such agreement is Article 6ter of the Paris Convention for the Protection of Industrial Property.
The purpose of Article 6ter is to protect, and prevent the registration and use of, trademarks that are identical with, or very similar to,
- armorial bearings
- flags and other State emblems
- official signs
- hallmarks
- other emblems
- abbreviations and names of international inter-governmental organizations
