Copyright and License Primer

Recently a case involving software licensing and copyright was discussed on an engineering list. Reading the discussion it became clear to me that it is likely that a majority of people don’t know how copyright and licensing go together. So I thought I’d write a brief primer on the basics of copyright in the 21st century. The particular case in that article illustrates how the wrong choice of license can lead to the loss of some rights that the copyright holder did not intend.

But I’m getting way ahead of myself here, let me start with the basics. First a disclaimer, I am absolutely, positively, not a lawyer. If you have any doubt about any copyright issue that could cost you money consult a copyright lawyer. Second point, I only know about US copyrights, the copyright laws in other countries may be very different. Final point, in this post I’ll be using the terms work and works to indicate any writing, painting, photo, video, music, graphics, software and other types of creative output that is protected by copyright law.

For readers closing in on 50 years old like me or, already past it, I’ll start with how it was before 1978. When I first learned about it the law of the USA was the Copyright Act of 1909. This law specified that copyright was something you had to intentionally place on works if you wanted protection. If you distributed a work without attaching a copyright notice and filing for copyright protection the work was considered public domain. With the adoption of the 1976 Copyright Act, which went into effect in 1978, this situation was reversed. Since 1978 any work a person creates receives full copyright protection immediately without any filing or adding of notices. This means that even a finger paint drawing a three year old creates is automatically protected as a copyrighted work of the three year old the moment it is created.

This gives us the two ends of the copyright spectrum, fully protected and public domain. Public domain works can be used in any way by any person with no restrictions. This means that if someone wants to they can take your public domain work and sell it for money without giving you any credit or money. Full copyright protection prevents everyone from doing almost anything with the work unless they previously were granted permission by the works creator. There is an exception to this known as “fair use” that does give some limited usage rights to critics, reviewers, buyers of the work and others. Fair use is a complicated topic that I don’t have time to cover in this post, see the Wikipedia article for more information.

Often the two ends of the spectrum don’t provide a content creator with a usable option. Putting your work in the public domain makes it difficult to earn a living from your works. Enforcing full copyright on your work severely limits your distribution options because you need to individually grant rights to your customers. When you want to retain control of your works but not burden yourself and your customers with individually granting rights, the solution is to apply a license to the work.

A license for a copyrighted work is a way to take some rights away from the copyright holder and give those rights to the customer. An example of a right most software companies and developers want to give their customers is the right to make archival copies for backup purposes. Without a license granting this right it could be a violation of copyright law for your customer to make a backup copy of the CD you gave them when you sold them the software. (Note fair use doctrine may give some archiving rights to the customer)

You should put a good deal of thought into choosing a license for your works because the wrong license could turn into a big problem. You can create your own license with the help of a copyright lawyer and this is what big businesses usually do. However the costs can be large and if there is a mistake in the license you could lose some of the rights you meant to retain. So, for individuals and small businesses the best solution may be one of the pre-made licenses that are freely available. The Free Software Foundation created and maintains the GNU General Public License (GPL) for software. While this is an excellent license created by some great legal minds it is very restrictive and may not be what you want. So other licenses have been developed such as the LGPL, BSD, Apache and others. For non-software works until recently there were not many choices other than full protection and public domain release. Thankfully the Center for the Public Domain recognized this need and has created the Creative Commons licenses for non-software works.
