A U.S.firm Seeking International Trademark Protection

A U.S.firm seeking international trademark protection:

A) need only file one application, in English, with the PTO, which sends the application to the World Intellectual Property Organization, which transmits it to each country in which the applicant would like trademark protection. This simplified process is available under the Trademark Law Treaty.
B) must complete an application, in the native language, for each country in which it would like to obtain trademark protection.
C) must, according to the World Intellectual Property Organization of the United Nations, file an electronic application in its central office which, if accepted, automatically provides trademark protection in all countries of the world.
D) must work through the Berne Convention and the National Intellectual Property Law Enforcement Coordination Council to obtain trademark protection in other countries.
