An example is the photocopy machine in public libraries. Another is the long-time tradition of making audio tape copies of music from a radio broadcast. Another example is time-shifting TV broadcasts for later viewing.
The USPTO says that copies of copyrighted materials can be sent to them under "Fair Use" when applying for for a patent, even though this is a commercial example: http://www.uspto.gov/about/offices/o...xamination.pdf
Also, Google indexes copyrighted materials found online, and Gogle books are also put online with (page count) limited access (and without permission), under "Fair Use".
So, even some forms of commercial "Fair Use" are allowed (but with less freedom than for personal use).
