Clark, I don't remember whether all of them were public or PM's with Lurgio or other IDCers. In general I don't like to burst bubbles in public, but if asked, ... . In total I've looked in detail at between 10 and 15 IDC patents over the last 2 or 3 years, many documented on SI (either public or PM). But I'll concede most aren't as bad as the one you referenced. Given that I do not keep an archive of my own posts, I'll leave it to you to find them. Sorry.
Don't mean to interrupt your conversation with Darrell, but I thought I could be of use providing some patent info compiled by renntech on RB.
The following does not include many other patents that have been applied for but have not been recorded.
Also, note patent no. 5991332. I think I read that this is the matched filter for air interface method and will be required in all 3G WCDMA systems.
