Development of Creative Commons licenses

[Sigmascape1 AT cs.com]

Hello!

I am new to the list. This is my first post.

Over the years, I've found intellectual property issues interesting, 
especially in the entertainment world. As a comic book fan, its really 
interesting to read about issue relating to 'who owns what characters.' I 
realize that CC is primarily concerned with copyright issues, and the various 
ways to free or partially free content by using various licenses. What about 
trademarks? For example, is there any way to create, using my comic book 
interest, a character, establish a formal or informal trademark on the 
character, and then create comic book content that would be then licensed 
under some sort of CC license, and use CC or a CC-like license the entire way?

>From what I have read while researching IP, a trademark must be 'defended' 
>so that it is preserved. Wouldn't the same be true of a standard copyright? 
>If I wrote a poem, and wanted to reserve all rights to it using the current

>protect it against someone else claiming ownership?

Hopefully, I am making sense. I'm just curious how far CC and CC-like 
concepts can be pushed when it comes to complete, end-to-end concepts 
relating to some IP.

Thanks!!!
