History Lesson
Sometime ago, we wrote about a U.S. patent being enforced in Puerto Rico – yes, Puerto Rico is part of the United States. Now, we write about a U.S. patent which is not being enforced in an Indian reservation, in Oklahoma, because the reservation is a separate nation and, in that respect, not part of the United States.
