Olympic related domain names

[Takwa]

I am from London, and recently registered two Olympic related domain names.
I then tried to park it with Sedo, then got told it was TRADEMARK, so i had to cancel them.

Anyway I check and found it on Nominet

and

http://www.london2012.com/about/our-bran...-brand.php

They even tried to Trademark 2012, a number and a date, I wonder how will they able to do that?

Olympic is a tradition from thousand of years ago, it's like getting "Christmas" or "New Year" trademark, not going to work is it?

Also the London2010 logo is making me go blind!
