A Utah judge has <A HREF="http://news.zdnet.com/2100-3513_22-6090252.html?tag=zdnn.alert">thrown out hundreds of claims</A> made by SCO Group in its Linux lawsuit against IBM, finding that SCO failed to specify many of Big Blue's alleged misdeeds. In a ruling filed this week in district court, Judge Brooke Wells agreed with an IBM motion to limit the scope of claims filed by SCO last year. The company launched its initial suit against IBM in 2003, claiming Big Blue's contributions to the Linux operating system included Unix code owned by SCO. IBM doesn't believe its Linux work infringed on any SCO copyrights, and it has questioned the validity of those copyrights.
