Sontag specifically claimed that there is "significant copyrighted and trade secret code within Linux".

When asked for examples of infringement, Sontag said, "It's all over the place" but did not characterize any one subsystem as containing more infringing code than others. Infringement is present not only in distributions and vendor kernels, but in the official kernel available from kernel.org. Code has been "munged around solely for the purpose of hiding the authorship or origin of the code", he said.

"I can't at this point lay out all the evidence", Sontag said [....]

[...] "We specifically excluded the BSD-derived code", Sontag said. "There is post-BSD UnixWare source code origined [sic] with SCO, and that is of issue."-- Chris Sontag, 2003-05-15
