Funny you mention it, but MP3 does have several patents covering aspects of it that expire between 2007 (fine) and 2017 (not so fine). There have been various companies at various times that have claimed licenses are required to encode/decode it. Fraunhofer Institute being a good example - they earned 100million euros in 2005 from mp3 licenses. In1998 they sent a lot of letters out to developers of software using mp3 stating that they needed a licence.
I guess the difference from G729 is that a) enough people in the general public use it and want to continue using it and b) the patent holders have declined to enforce license fees on free/foss software, only focussing on commerical software, so there's plenty of stuff around that can use it without worrying too much about the patents.
