I was checking a couple links and found a 404, so I tried them all(tab browsing is nice). The following links are 404 or "article gone". I didn't verify the actual contents of the other links, but at a brief glance they seemed to have the appropriate subject matter.
Q4 Patent Suits - Wall Street Journal - Microsoft faces host of patent suits
Q6 Sendo Sues Microsoft - Reuters - Sendo Sues Microsoft
Q7 Intertrust Suit - The Register - InterTrust sues Microsoft (on just about everything)
M1 Marketing - The Register - Experiences at a Firm Hostile to Free Software

The reference #s also seem odd - some start with 1, others 0, one section begins with 5. In the X section there's two 41s and lots of #s skipped.
