It looks like this could go either way. On one hand the surname Purdue has been around since the 1500's or so, well before the University. Furthermore I don't think that you can trademark a surname. Now if you had used PurdueUOnline.com then that is a clearer case against you. The only thing I would do is remove direct references to "Purdue University" from the page. Which in a way defeats the purpose of the site as a resource. You can check out the site http://www.netpolicy.com/ as they may be able to help you find counsel. DO NOT GIVE UP! Far too many people are rolling over when it comes to this. There will come a time in the near future where the courts will have to do some serious re-evaluation of the trademark process. If it keeps going like this you'll have people trademarking words like "the" or "and" and trying to charge royalties. Come on!
