RealNetworks has applied for one or more patents on technology related to

disclose those patents and license them under openly specified and
non-discriminatory terms, and furthermore will not enforce those patents
necessary to comply with the RTSP specification when used solely to implement
RTSP. This will apply irrespective of whether or not the licensee has any
business relationship with RealNetworks. Given where RealNetworks is in

RealNetworks intends to disclose such information as soon as it is
