You simply can't write it anymore without an R inside a circle or (R) [parenthesis]. Or something like that.
Attorney Dave Barry filed suit to challenge the NAR's use of the term "Realtor." Apparently, it also had something to do with ownership and sale of the realtor.com website. Go figure. Someone wanted money.
In any event, the Trademark, Trials and Appeals Board thought the term was trademarked by the NAR. The argument was over whether the term "Realtor" was generic or unique. Apparently, unique won out.
I guess "real estate agent" is still available for those of you who are looking for help buying a house.
