Not (just??) the use of the name, the use of the data structures necessary to R/W the file are copyrighted.

From the PDF spec. (Hopefully a "fair-use" situation)

"The only condition of such copyright permission is that anyone who uses the copyrighted list of data structures and operators in this way must include an

appropriate copyright notice. This limited right to use the copyrighted list

of data structures and operators does not include the right to copy this book,

other copy-righted material from Adobe, or the software in any of Adobe's products that use the Portable Document Format, in whole or in part, nor does

it include the right to use any Adobe patents (except as may be permitted by

an official Adobe Patent Clarification Notice)."

My apologies for speaking from ignorance.

It's a pretty common misconception in the industry...

I have found the PDF File Format document on Adobe's site, and it appears that all that is required to R/W PDF is a Copyright notice in your application.

A copyright notice on the name "PDF", that's true. But isn't the name "TIFF" also a copyright of Adobe? (although they should really be trademarks not copyrights, but ...)
