Based on the information that you’ve provided here, I think you were correct and your neighbor was wrong. The definition of an easement is “the right to use the real property of another for a specific purpose.” In the case you describe, the easement benefitted the utility companies. HOWEVER, you have to be very careful to avoid an easement being created by the course of use. If you allow easement type use of your property for a sufficient period of time, an easement may be created. The laws are different in different jurisdictions, but it’s always good to let people know that although you are allowing them to cross your backyard (or whatever) you have no intent to create an easement. It’s kind of tricky . . .
