-to program. For our safety (which includes yours), we try to avoid
-using algorithms and techniques that we know are patented in the US or
-elsewhere, unless the patent looks so absurd that we doubt it will be
-enforced, or we have a suitable patent license allowing release of free
-software.

-Beyond that, sometimes the GNU project takes a strong stand against a
-particular patented technology in order to encourage everyone to
-reject it. For example, until the GIF patents expired in 2006, we
-specified that GNU packages and web pages should not include GIF image
-files, and that equal or better support for other image formats such
-as PNG and JPEG was crucial. (These other formats remain superior, so
-there is still no particular reason to use GIF's.)

-Software patents are not the only matter for ethical concern. A GNU
-package should not recommend use of any non-free program, nor should it
-require a non-free program (such as a non-free compiler or IDE) to
-build. Thus, a GNU package cannot be written in a programming language
-that does not have a free software implementation. Now that GNU/Linux
-systems are widely available, all GNU packages should function
-completely with the GNU/Linux system and not require any non-free
-software to build or function.
+to program. There are so many software patents in the US that any
+large program probably implements hundreds of patented techniques,
+unknown to the program's developers. It would be futile and
+self-defeating to try to find and avoid all these patents. But there
+are some patents which we know are likely to be used to threaten free
+software, so we make an effort to avoid the patented techniques. If
+you are concerned about the danger of a patent and would like advice,
+write to @email{maintainers@@gnu.org}, and we will try to help you get
+advice from a lawyer.

+For example, the MP3 audio format is covered by a software patent in
+the USA and some other countries. A patent holder has threatened
+lawsuits against the developers of free programs (these are not GNU
+programs) to produce and play MP3, and some GNU/Linux distributors are
+afraid to include them. Development of the programs continues, but we
+campaign for the rejection of MP3 format in favor of Ogg Vorbis format.

+should it require a non-free program (such as a non-free compiler or
+IDE) to build. Thus, a GNU package cannot be written in a programming
+language that does not have a free software implementation. Now that
+GNU/Linux systems are widely available, all GNU packages should
+provide full functionality on a 100% free GNU/Linux system, and should
+not require any non-free software to build or function.
+The GNU Coding Standards say a lot more about this issue.
