10 Myths About Copyright
1) "If it doesn't have a copyright notice, it's not copyrighted."
This was true in the past, but today almost all major nations follow the Berne copyright convention. For example, in the USA, almost everything created privately and originally after April 1, 1989 is copyrighted and protected whether it has a notice or not. The default you should assume for other people's works is that they are copyrighted and may not be copied unless you know otherwise. There are some old works that lost protection without notice, but frankly you should not risk it unless you know for sure.
2) "If I don't charge for it, it's not a violation."
False. Whether you charge can affect the damages awarded in court, but that's main difference under the law. It's still a violation if you give it away -- and there can still be serious damages if you hurt the commercial value of the property. There is an exception for personal copying of music, which is not a violation, though courts seem to have said that doesn't include widescale anonymous personal copying as Napster. If the work has no commercial value, the violation is mostly technical and is unlikely to result in legal action. Fair use determinations (see below) do sometimes depend on the involvement of money.
3) "If it's posted publicly on some site it's in the public domain."
False. Nothing modern and creative is in the public domain anymore unless the owner explicitly puts it in the public domain. Explicitly, as in you have a note from the author/owner saying, "I grant this to the public domain." Those exact words or words very much like them.
4) "My posting was just fair use!"
The "fair use" exemption to (U.S.) copyright law was created to allow things such as commentary, parody, news reporting, research and education about copyrighted works without the permission of the author. That's vital so that copyright law doesn't block your freedom to express your own works - only the ability to appropriate other people's. Intent, and damage to the commercial value of the work are important considerations. Are you reproducing an article from the New York Times because you needed to in order to criticise the quality of the New York Times, or because you couldn't find time to write your own story, or didn't want your readers to have to register at the New York Times web site? The first is probably fair use, the others probably aren't.
5) "If you don't defend your copyright you lose it." -- "Somebody has that name copyrighted!"
False. Copyright is effectively never lost these days, unless explicitly given away. You also can't "copyright a name" or anything short like that, such as almost all titles. You may be thinking of trade marks, which apply to names, and can be weakened or lost if not defended.
You generally trademark terms by using them to refer to your brand of a generic type of product or service. Like an "Apple" computer. Apple Computer "owns" that word applied to computers, even though it is also an ordinary word. Apple Records owns it when applied to music. Neither owns the word on its own, only in context, and owning a mark doesn't mean complete control -- see a more detailed treatise on this law for details.
6) "If I make up my own stories, but base them on another work, my new work belongs to me."
False. U.S. Copyright law is quite explicit that the making of what are called "derivative works" -- works based or derived from another copyrighted work -- is the exclusive province of the owner of the original work. This is true even though the making of these new works is a highly creative process. If you write a story using settings or characters from somebody else's work, you need that author's permission.
There is a major exception -- criticism and parody. The fair use provision says that if you want to make fun of something like Star Trek, you don't need their permission to include Mr. Spock. This is not a loophole; you can't just take a non-parody and claim it is one on a technicality. The way "fair use" works is you get sued for copyright infringement, and you admit you did copy, but that your copying was a fair use. A subjective judgment on, among other things, your goals, is then made.
7) "They can't get me, defendants in court have powerful rights!"
Copyright law is mostly civil law. If you violate copyright you would usually get sued, not be charged with a crime. "Innocent until proven guilty" is a principle of criminal law, as is "proof beyond a reasonable doubt." Sorry, but in copyright suits, these don't apply the same way or at all. It's mostly which side and set of evidence the judge or jury accepts or believes more, though the rules vary based on the type of infringement. In civil cases you can even be made to testify against your own interests.
8) "Oh, so copyright violation isn't a crime or anything?"
Actually, in the 90s in the USA commercial copyright violation involving more than 10 copies and value over $2500 was made a felony. So watch out. (At least you get the protections of criminal law.) On the other hand, don't think you're going to get people thrown in jail for posting your E-mail. The courts have much better things to do. This is a fairly new, untested statute. In one case an operator of a pirate BBS that didn't charge was acquited because he didn't charge, but congress amended the law to cover that.
9) "It doesn't hurt anybody -- in fact it's free advertising."
It's up to the owner to decide if they want the free ads or not. If they want them, they will be sure to contact you. Don't rationalize whether it hurts the owner or not, ask them. Usually that's not too hard to do. Time past, ClariNet published the very funny Dave Barry column to a large and appreciative Usenet audience for a fee, but some person didn't ask, and forwarded it to a mailing list, got caught, and the newspaper chain that employs Dave Barry pulled the column from the net, pissing off everybody who enjoyed it. Even if you can't think of how the author or owner gets hurt, think about the fact that piracy on the net hurts everybody who wants a chance to use this wonderful new technology to do more than read other people's flamewars.
10) "They e-mailed me a copy, so I can post it."
To have a copy is not to have the copyright. All the E-mail you write is copyrighted. However, E-mail is not, unless previously agreed, secret. So you can certainly report on what E-mail you are sent, and reveal what it says. You can even quote parts of it to demonstrate. Frankly, somebody who sues over an ordinary message would almost surely get no damages, because the message has no commercial value, but if you want to stay strictly in the law, you should ask first. On the other hand, don't go nuts if somebody posts E-mail you sent them. If it was an ordinary non-secret personal letter of minimal commercial value with no copyright notice (like 99.9% of all E-mail), you probably won't get any damages if you sue them. Note as well that, the law aside, keeping private correspondence private is a courtesy one should usually honour.
11) "So I can't ever reproduce anything?"
Myth #11 (I didn't want to change the now-famous title of this article) is actually one sometimes generated in response to this list of 10 myths. No, copyright isn't an iron-clad lock on what can be published. Indeed, by many arguments, by providing reward to authors, it encourages them to not just allow, but fund the publication and distribution of works so that they reach far more people than they would if they were free or unprotected -- and unpromoted. However, it must be remembered that copyright has two main purposes, namely the protection of the author's right to obtain commercial benefit from valuable work, and more recently the protection of the author's general right to control how a work is used.
While copyright law makes it technically illegal to reproduce almost any new creative work (other than under fair use) without permission, if the work is unregistered and has no real commercial value, it gets very little protection. The author in this case can sue for an injunction against the publication, actual damages from a violation, and possibly court costs. Actual damages means actual money potentially lost by the author due to publication, plus any money gained by the defendant. But if a work has no commercial value, such as a typical E-mail message or conversational USENET posting, the actual damages will be zero. Only the most vindictive (and rich) author would sue when no damages are possible, and the courts don't look kindly on vindictive plaintiffs, unless the defendants are even more vindictive.
The author's right to control what is done with a work, however, has some validity, even if it has no commercial value. If you feel you need to violate a copyright "because you can get away with it because the work has no value" you should ask yourself why you're doing it. In general, respecting the rights of creators to control their creations is a principle many advocate adhering to.
