The link I posted is public information; I can't say more than that (and don't remember much in any case). Normally the "prosecution history" documents would be available online [0], because they're also a public record, but for this patent that doesn't appear to be the case (it was a long time ago, so possibly the USPTO just hasn't yet digitized the documents). It's been some time since I did patent-application work so I'm probably not up to date on USPTO procedures and resources.
