SCO seeks more code from IBM

The SCO Group appears to be experiencing difficulties in identifying the specific lines of code, which it alleged IBM improperly contributed to the Linux operating system, according to court documents.

In the filings, SCO asked the court to order IBM to produce more materials documenting the development of its AIX and Dynix operating systems, and argued that the files that IBM has produced to date are "incomplete".

In March, courts ordered IBM to provide SCO with source code to the two operating systems. SCO now claims that "the files previously produced by IBM pursuant to this court's order show that IBM improperly contributed code to Linux".

However, SCO's filings provide few details on the nature of these "improper" contributions.

Since launching its multibillion-dollar lawsuit against IBM last March, SCO has provided some examples of alleged intellectual property (IP) violations within the Linux source code, all of which have been strongly disputed by the open-source community.

The question of whether or not SCO even owns the copyright to the Unix System V source code is unanswered, and SCO and Linux supplier Novell are engaged in a legal dispute over the matter.

The court has also ordered SCO to respond to IBM's discovery demand that it identify the specific lines of code that it claimed IBM contributed to Linux.

SCO has, apparently, had difficulty accomplishing this task. The filings list a number of steps SCO has taken to identify the IP violations, but added, "these efforts have not, however, yielded much of the information required for SCO to further respond to IBM's discovery demands".

"SCO has attempted to follow IBM's scattered path through the winding history of countless alterations, derivations and revisions, but the task is nearly impossible without a map, a map so easily accessible to IBM," the filings said.

More documentation of IBM's source code and developer contributions is needed for SCO to respond to IBM.

The filings raise questions about how much evidence SCO actually has about any IBM wrongdoing with respect to Linux, given that SCO already has access to the open-source Linux source code, said Jeff Norman, an intellectual property partner with a Chicago law firm.

"We're talking about open-source code. The code is out there," he said. "For them to say that they can't respond to IBM's request to identify specific items of code they are infringing, I just don't understand that. I don't think the judge is going to understand that."

"Either they know that there's code that's infringing or they're just fishing," he said.
