This thread.. i have seen things on this before but the link to patents was neat.. (thanks shadokat).
I looked up Pi Phi and found out that we have the design of how our letters apear on our badge trademarked. I dont think you can have the letters but I guess a specific design. It would be interesting to know if there are more things that we have patented or trademarked.
Back to the post.. I know that it would be frustrating to see someone with the same name as your organization, but there is really nothing you can do unless they are trying to portray themselves as you.. which it doesnt appear like they are doing. All those freedoms we have.. gosh
(I am just going off my own knowledge of the matter.. I could be wrong)
