How could quoting a spec NOT be >considered fair use. A) Fair use is what a US court says it is. The law provides factors for courts to weigh but no bright line rules. Anyone who says that a particular usage definitely is or isn't fair use without a court decision to back it up doesn't understand the law. B) Court decisions have been all over the place. In one extreme case, use of a single sentence was found to be infringing. (It was from a medical text, quoted in a cigarette ad.) C) Copyright litigation is fantastically expensive, and in the U.S., even if you win, you usually still have to pay your own costs. Don't go there. D) Fair use only applies in the U.S. Some other countries have Fair Dealing, but the rules are different, so if something is fair use in the US, that doesn't mean it's fair dealing elsewhere. Most other countries also have moral rights which further constrain what you can quote without permission. It's not unreasonable for an SDO to want clear permission about what it uses. R's, John
