Computer software is generally copyrighted just as a book is. Unlike a book, it is difficult to use just a small portion of it and call it fair use. Computer software can be sold, licensed or freely distributed. Just because software might be free, does not mean it is not copyrighted or that there is no license dictating terms of use.
A license is a legal agreement between you and your software publisher. The license spells out what you can and cannot do with the software. It might specify the number of computers on which the software may be installed or address resale rights. Software may include a validation feature as a check on proper use. There are several categories of software and licenses.
Common Types of Software and Licenses
Common types of Software and Licenses
Shared source - Microsoft developed “shared source.” There is not one standard license for shared source, there are several. When using this software, read the accompanying restrictions on use.
Shareware is proprietary software that is distributed freely or at low cost as a way for users to test drive copyrighted software they are interested in purchasing. Shareware will usually come with a license and registration. Shareware often distinguishes between commercial and non-commercial use.
Freeware – Although free, this software is copyrighted. It may have proprietary code or it may be open source software. It could even be in the public domain. Look for possible restrictions on use.
Open Source (OS) software is copyrighted, but the copyright holder ascribes to the OS license principles. OS comes with a license that uses special criteria known as Open Source Definition (OSD) established by the Open Source Initiative. See OSD for the ten principles. This is non-proprietary software. It can be downloaded, modified and redistributed. Commonly known OS software examples include Apache and Mozilla.
Implied License - This sort of license may appear on the box or in the printed information that comes with purchased software. There will be wording that states that your use of the software implies consent to the terms of use. (Simpson 88)
Shrink Wrap Licenses- These licenses are found after the buyer tears off the shrink wrap and opens the box. While “shrink wrap” licenses have been found to be unenforceable in some cases, one cannot assume this is will always be true.
Click Wrap License- Also known as “click through,” this is similar to a Shrink Wrap license, but we find these all over the web or on CDs. The user is required to agree to terms before using the service.
Copyleft License- This liberal license retains copyright for the creator, but allows the user to modify and distribute the software with the understanding that “downstream” users will be equally generous. GNU (General Public License) is a copyleft type of license.
Public Domain software – this is software that has no copyright restricting its use, no license, it’s free for you to use any way you wish.
Copyright Law and Software
If computer software is wrapped inside so many types of licenses, what does the exemption in the law allow me to do? ( Copyright Law, Title 17, Chapter 1, Section 117 Limitations on exclusive rights: Computer Programs)
The purchaser of an original copy of a computer program may “make or authorize the making of another copy or adaptation of the computer program provided:
(1) that the new copy or adaptation is created as an essential step in using the program on one’s computer [an ephemeral copy] and that it is used in no other manner, or
(2) that such new copy or adaptation is for archival purposes only and that all archival copies are destroyed in the event that continued possession of the coputer program should cease to be rightful.”
The making of an archival copy permitted under this section of the law does not apply to software that is licensed unless the license allows it. (Simpson 89)
If a computer needs maintenance or repair, section 117 allows the owner or lessee of the computer to make a copy of a computer program in order to make the repair. This extra copy made in order to repair the computer must be destroyed immediately after the repair is made.
Original copies of software and copies made from originals may be “leased, sold or otherwise transferred…only as part of the lease, sale or other transfer of all rights in the program.” Adaptations “may be transferred only with the authorization of the copyright owner.” However, if your license speaks to the lease, sale or transfer of software, you must abide by those stated restrictions.
Computer software is tangible material and can be copyrighted. The Doctrine of Fair Use applies to computer software.
