Quizplus · Accepted Answer

A fundamental principle of trademark law is first in time equals first in right.Under the principle of first in time equals first in right,priority ordinarily comes with earlier use of a mark in commerce.It is not enough to have invented the mark first or even to have registered it first.This is because of the territoriality principle,which says that priority of trademark rights in the United States depends solely upon priority of use in the United States,not on priority of use anywhere in the world.Earlier use in another country usually does not count.
