What is it about?

The registration of a trademark in several states or in a region can be a repetitive and complex process. The 1994 Trademark Law Treaty (TLT) facilitates this process by encouraging states and regional bodies to harmonize and simplify their trademark registration procedures. The provisions of the TLT regulate applications for registration, changes after registration and renewal; they simplify the procedure for authorizing powers of attorney and revise documentation requirements. This Treaty does not apply to hologram marks and to marks not consisting of visible signs, in particular, sound marks and olfactory marks.

Why is it relevant?

The implementation of simplified and uniform procedures reduces the costs linked to the registration of trademarks and the risk of error.

Additional Information
