Under what circumstances is it invalid to register multiple trademarks:

In trademark practice, the expression of "invalidation declaration" is often seen. So, what is invalidation? Under what circumstances does an enterprise need to declare a trademark invalid? Combining with specific cases, the author of this paper explains the specific scene and application of trademark invalidation in practice, which is helpful for trademark owners to better use legal means to safeguard their legitimate rights and interests. It is hereby published, so please pay attention.

The invalidation of a trademark refers to a system in which the Trademark Office declares the trademark invalid ex officio or the Trademark Review and Adjudication Board decides whether to declare the trademark invalid at the request of the obligee after the trademark is registered. Generally speaking, there are mainly the following situations that need to start the invalidation procedure.

(1) According to the new Trademark Law, which came into effect on May 1, 214, if a trademark is challenged but failed, it will be registered directly. The original objector can only file a further declaration of invalidation after the trademark registration.

(2) Some trademarks were not monitored by the obligee during the announcement period of preliminary examination. After the registration was approved, the obligee found that the trademark was detrimental to his own rights and interests and filed an invalidation.

for example, the graphic trademark No.777442 is similar to the graphic trademark (cited trademark) of Tongwei Group, but it is not easy to be monitored during the announcement period because it is a graphic trademark. After the registration was approved, the obligee found the trademark, filed an invalidation declaration and got support.
