Hi!

You're confusing what derived works are.  If a document calls for a
given font, and the user must provide that font on their computer,
it's not a derived work.  If the document contains a *copy* of the
font so that the user *doesn't* have to have a copy (this is what the
web would have to do), that's a derived work.  If the document
contains the *results* of using the font (PDF does this), it's not a
derived work.

If you print out that document and give it away, there are lots of copies of the glyphs on the paper.

In the case of gschem symbols or pcb footprints, the project file
contains a *copy* of the symbol/footprint.  Thus, it's a derived work.
The gerber files, IMHO, don't contain a copy of the footprint (they
contain the results of applying that footprint), and an etched board
certainly doesn't.

The gerber files as well as the etched board are the result of transforming the symbol/footprints. It is like compiling the source code of a GPLed program. This does not remove GPL restrictions.

And a more appropriate example (for us) is: The use of Word to create
a document doesn't mean the document belongs to Microsoft,

Because the licence of word explicitely grants you the right to create documents using wornd and keep the copyrigth.

The GPL requires you to use the GPL for derived work. It is up to the copyrigth holder to place any restictions to its use ot not.

Similarly, the use of pcb to create a board doesn't mean the board is
limited by pcb's license, but the use of pcb's footprints *does* mean
the board file is limited by the footprint's license.

The font never changed. 

That's actually evidence that it *is* a derived work, if the document
contains an unchanged copy of the font.
