Seems that a paralegal has taken up the task of researching the SCO lawsuits, claims and FUD and documenting them on a website. I like the approach the author takes:
SCO Scoop. When you want to know more about the story but don't know where to look. IANAL. I am a paralegal, so if you have a legal problem and want advice, this isn't the place. Hire an attorney instead. Research is, however, what paras do, so here I am sharing things I have found in my research.
Lot's of interesting information including a link to IBM's copyright infringement counterclaim.
