Unless excluded in the settlement between OU and OSU, that flag would be a violation. 

When traveling by plane, I often wear a blue blazer with an OHIO lapel pin.  After significant wins like Pitt, Michigan, etc., I often heard a Go Bobcats.  Lately though the reference has been to Ohio State.  

You're being sarcastic, right?!

The close ups of the cheerleaders and hearing them yell "let's go Ohio" just about made my head explode. I think it's time to revisit that agreement because I am sick of Ohio A&M Violating OUr name!

To succeed in any such action, Ohio would have to demonstrate that it has been zealously protecting its rights under the settlement. 

Our agreement with them permits "traditional" uses of Ohio in their athletic marketing, from Ohio Stadium to their iconic track & field uniforms, and I'm assuming those flags are included.

I'm not sure I'd make the same assumption, Tim.  My memory could be flawed - it often is - but I seem to recall that the settlement required OSU cheerleading sweaters to read Ohio State the first time new sweaters were ordered after the settlement.  My memory is not as clear on the track unis.

(Note: my memory is based on correspondence with retired Ohio legal affairs director John Burns who kept me plugged in on the settlement process as a result of my having provided some insights into registering logos and brandmarks.  But all of this now goes back how many years?  I do recall The Wall Street Journal having fun with the OU/OSU dispute and ditto Matt Lauer on his Today Show.)

Police will tell you that they get their man because of the tips they get; terrorism we are told is thwarted by the eyes of the public.  So with that in mind I encourage each of you in a non-azzwhole way of letting people know the difference.

For instance, on Saturday, a Facebook friend of my wife right before the O$U kickoff typed O-H-I-O and had lots of likes hit her comment.  I typed S-T-A-T-E?  O-H-I-O was idle.

The friend can remain ignorant or she can figure she did something... It is up to us to let those who make the error understand the difference.

Personally, I think their OH  IO cheer is lame.  It would seem to be much better to have after the two sides do their part that the entire group then yell S-T-A-T-E.  An accent on the STATE part would be ear shattering when they do it together and I'd think would sound completely BAD AZZ

Why did OHIO University wait until 1995 to trademark OHIO?

There was also the issue of traditional and historic use.  When we could supply newspaper examples dating back to the 1890s of our teams being called "OHIO" and A&M's teams wearing jerseys that just said "OSU," it was important evidence in the case.  I forget the exact term that the lawyers used for this, but it was kind of a defacto copyright in the absence of any formal grant of copyright to either party.  As John Burns told me, it was very crucial evidence in convincing the OSU attorneys that they were going to be the losers if the case ever went to trial.  I do think we gave up too much in the out-of-court settlement.  Glidden and the president of OSU Kirwin (sp?) were good buddies and, therefore, Glidden was, perhaps, a little too lenient in those final negotiations.  From my memory of the settlement, the O-H-I-O flags are a violation of the agreement as well as the band wearing little diamonds on their hats saying "OHIO."  The things that were grandfathered in included "Ohio Stadium" and "Script Ohio."  Cheerleader uniforms were not.  As Mike said they were permitted to continue to use their "OHIO" cheerleader uniforms for a few years until they wore out; which occurred a number of years ago.   Like, Mike, I played a very minor role in helping develop some evidence for this case.  

I recall seeing a thread about this specifically, but an item like this falls under a violation of the trademark agreement, no?

It's kind of hard to tell, but it looks like there might be some kind of trademark simple at the end.
