More precisely H.323 - and the related signalisation protocols - have no
patents, but H.323 can make use of patented audio and video codecs. SIP
has the same problem. 

However, GnomeMeeting/OpenH323 do not make use of any of those patented
codecs, which doesn't prevent interoperation with other H.323 endpoints
as the use of those patented codecs is optional. You are entirely free
to use whatever codec you want with H.323, patented or not.
