presumably not free. Even though the patent holders have never even
tried to start legal action on mp3 codecs anywhere, and have said that
they have no intention of going after anyone, they also have not
released them under GPL or any other "free" license.
The fedora home page does have this to say on the subject though:
"The goal of The Fedora Project is to work with the Linux community to
build a complete, general purpose operating system exclusively from free
software."
Since mp3 is not free, redhat won't use it. Presumably this would also
apply to code that is copyrighted, but not patented too.
Disclaimer: IANAL.
There are three matters.
1. Trademarks.
Trademarks have to be enforced or they're lost. Australian companies have
been making ugg boots for 30 years or so to my memory. Now some American
company is claiming it as a trademark. I predict they'll lose if a court
adjudicates, but of course the "infringers" may not have enough money to
spend on it.
2. Patents.
Patents require registration and renewal in all jurisdictions, and have a
limited lifespan. Patents can be enforced discriminatorily: IBM can choose to
not enforce patents against some people (say OSS developers) and go after
others (say Bill). I would trust IBM to do just that, whereas I expect Bill
will sue all.
Note that most countries do not recognise software patents.
3. Copyright.
In most jurisdictions, an author owns copyright unless his wok explicity
denies this ("this work is in the public domain"). The major exception is
commissioned work: if I hire you to paint me a picture of Bill receiving a
pie in the face, I own the copyright unless our contract says otherwise.
In some jurisdictions (eg .de), copyright cannot be assigned. A copyright
owner can impose restrictions on the use of his work: he permits its use
under a licence.
In public domain works, the author disclaims all rights of ownership. As I
understand "public domain," I can take a public domain work and claim it
(perhaps with minor modifications) as my own.
A complete work can have many copyright holders. Think of a performance by the
Boston Pops Orchestra. The composer holds copyright on the score. Then
arranger has copyright over the arrangement, Importantly, each performer
(annd conductor) has copyright over her contribution. And if the performance
is recorded, there are more copyrights there too.
It is copyright law that underpins all OSS licences.
Patents tend to lie in hiding (eg Amazon's one-click patent) and can be
destroyed by prior art. OSS developers cannot keep up (indeed corporates
can't), and for the moment I prefer to ignore them until they pop up. OTOH I
do not recommend "fingers in ears."
