Call Me Crazy...

What's the one thing missing from the US Trademark & Patent Office website home page? How about a copyright notice? How about a trademark notice? None of these elements is listed. For example, check out the official government logo on the upper left hand side. Notice anything missing? Look at the bottom of the page where the following copy is written: "This is the only official website of the United States Patent and Trademark Office." Notice anything else missing?

If the logo is truly official, wouldn't it be copyrighted and wouldn't the (c) be referenced on/at/near the logo or somewhere else on the page? What about the content of the site itself?

Lots of questions here and I'm sure there will be many more, especially in light of Lawrence Lessig's speech on copyright law and if we've gone too far in terms of regulation.
