Subject: RE: [rights] An effort to clear up the confusion over CG patent c laims
All,
There has been some confusion, in
part based on recent inaccurate media coverage, of XrML's relationship with
ContentGuard's IP claims. ContentGuard's intellectual property consists of
patents describing DRM technology.
Only one of the many technologies described in the patents is a rights
language. The connection between
the patented technologies and XrML is their common original source:
ContentGuard. XrML itself is not
mentioned in those patents. XrML
represents an instance of a rights language (and the best one created to
date). A licensing agreement with
ContentGuard is necessary for using the technology described in the patents, not
for using XrML. We believe that our technology provides a superior platform upon
which to build an XrML-based DRM system.
We recognize the possibility that DRM implementations using XrML may
theoretically not infringe the patents.
We have also outlined much of this on our website at:
