I cannot find a good source of information in regard to the legal status of some libraries and applications in Ubuntu 11.10, and I am hoping to find some answers here.
Firstly, it seems Ubuntu includes libjasper1 by default, the legal status of which in the United States, as I understand it, may not be in the clear, as JPEG-2000 may not be free to distribute. What is the story here? If the U.S. cracks down on software patent infringement, will this affect Ubuntu deployments in the U.S.? I really don't care about people's opinions on the legitimacy of such laws, nor do I want any advice to the effect that I should ignore them. I want a straight answer about reality as it is now.
Secondly, even when you disable Multiverse, software like Audacity and Inkscape are still available, I guess in Universe, and can easily be installed along with legally questionable dependencies. Audacity should not be packaged with mp3 import support by default in Ubuntu, but it is, having libmp3lame and libmad0 as dependencies, which encodes and decodes mp3. My understanding is that even decoding mp3 is not legal in the United States and Japan among others. Inkscape requires Imagemagick, which also includes JPEG-2000 support. Thus, perhaps there are packages that should be in Multiverse that are not.
Certainly Audacity's libmad0 is a functioning mp3 decoder that is not exclusively in Multiverse, and libmp3lame (which I believe allows encoding) is also easily available with Multiverse disabled, and are also unnecessary dependencies for Audacity. Fedora, for example, just builds Audacity without mp3 support. Furthermore, libjasper1 is a dependency of nearly everything in the default Ubuntu system, which is odd. It seems that you cannot open or save .jp2 files in ImageViewer.
Anyhow, I need to know what the legal status of these libraries and programs are so that I can safely install Ubuntu and travel with Ubuntu. I hope to get an answer soon.

The best advice that can be given is that the user makes their own decision, based on their conscience, the country they are in, and taking into account the following:
http://en.wikipedia.org/wiki/MP3

While you can legally distribute and use the MP3 format, the content of these files is what gets you "in trouble" i.e. you can't distribute Copyrighted Content such as Songs and make profit but of course you can use (listen to) them.
don't license end-users).

If you live in a country where it is legal to use this format, to encode MP3s, you can use Sound Juicer which uses gstreamer and the LAME mp3 encoder. The following should also work with other programs that use gstreamer:
ubuntu-restricted-extras
(which is not included by default, it is the end-user that chooses to install it).(It is illegal to copy music from a CD and redistribute it unless you have the copyright owner's permission).
You can legally use the Fluendo MP3 decoder available in the Partners repository.
If anything you are better of using:
Ogg Vorbis, and FLAC are patent free.

JPEG 2000 Legal issues
JPEG 2000 is by itself licensed, but the contributing companies and organizations agreed that licenses for its first part—the core coding system—can be obtained free of charge from all contributors. The JPEG committee has stated:
However, the JPEG committee has also noted that undeclared and obscure submarine patents may still present a hazard:
Because of this statement, controversy remains in the software community concerning the legal status of the JPEG 2000 standard.
However, many Linux distributions include a JPEG 2000 library

“GPL” stands for “General Public License”. The most widespread such license is the GNU General Public License, or GNU GPL for short. This can be further shortened to “GPL”, when it is understood that the GNU GPL is the one intended.
