the NAR is very aggressive defending their trademarks, they somehow managed to get a TM for the word Realtor, which I think is fishy and I would hope someone would take them to court over it, but very few people have the $$$$$ to fight a lawsuit, I think some things are not right there, the way they got this trademark and how they defend it.. they dont allow anything with the word realtor in it, its a big lobby with deep pockets, but maybe a california jury would decide in your favor..
