It's possible to get a patent on almost anything, especially recently, 
where the PTO tends to err on the side of issuing, and letting some 
subsequent infringment action deal with prior art invalidating it.  On 
the one hand, this sort of cheapens the whole examination process; on 
the other, it saves a bunch of  taxpayer money, since the vast majority 
of patents are never used/litigated/etc., so why spend lots of examiner 

The other thing is that it's fairly common to have a pretty broad 
reaching description in the disclosure, but very narrow claims.  If 
patents are being used as a marketing tool, heck, you don't really care 
what the claims are (claim 23: An antenna, as described in claim 1, 
where the coating is paint; claim 34: An antenna, as described in claim 
23, where the paint is red;), or even if the patent will eventually 
issue.  You just want to say "patent pending" in your literature to 
discourage competitors from copying it.

And if the patent does issue, it becomes part of your "intellectual 
property portfolio" and useful either as something to use for cross 
licensing with another company's portfolio or as something cool to show
