To determine whether a trademark agency is the best choice, you can refer to the following indicators:

Whether it is a registration agency unit of the State Trademark Administration.

Whether the agency's own brand trademark has been registered.

Whether the company has been established and operated for more than 5 years.

Look at whether the legal person of the company has passed its 30th anniversary, at the same time, whether the legal person has strong connections, and whether the legal person has excellent character.

Whether it has been operating at the same office address for more than 3 consecutive years.

Whether to implement ISO system management.
