There is more about the in's and out's of the whole thing here:

Regarding model kits: the Inspector was partly right: you won't see Boeing's name on any model kits unless the model company paid for the right to do so. It may sound reasonable at first, but what the aircraft companies are doing is asserting more rights than they have: trademarks exist to prevent brand confusion. Since there is little danger of confusing a 1:32 scale plastic model with a real 707 built by Boeing, it should not really qualify for trademark protection. It is, in fact, possible to hold a trademark for an identical name in one of over forty different trademark categories. Sadly, the categories are not well thought out, and the trademark office suffers from the same lack of sensible warm bodies that the patent office does, so it is easy for companies to trademark stuff that shouldn't even qualify for trademark protection. (Like "B-24")
By charging licensing fees they are not entitled to, they are stifling the efforts of smaller model manufacturers and game developers who cannot afford such fees. This is also why existing model kits cost so much more today than they used to.
Grumman tried the same stunt with Ubisoft games, effectively preventing them from including the TBM in their otherwise excellent flight sim, Pacific Fighters. As is typical in these cases, the smaller company caved to the threat of a costly legal battle that Grumman most likely would have lost had it actually gone to trial.
Here's an interesting thread on the issue, albeit an old one.

I'd be curious to hear how the proposed legislation is coming along...anybody know?
Edit: This is the latest thing I can find on the issue:
